Rear Upright Spherical Bearings (RUSB) Group Buy

Payment instructions posted at the end of this post! Deadline extended to July 7th!

Introduction

This is the ultimate chance at getting true top quality parts for your S chassis or Z32 to replace ALL the rubber bushings in your Z32 rear uprights with low friction, no play spherical bearings. These spherical bearings use high quality USA-made QA1 teflon-lined spherical bearings and 6061-T6 aluminum machined parts made by a top notch USA machine shop that primarily works in the Aerospace field. I’m a Mechanical Engineer in the Aerospace field, and have personally designed and tested these parts on my own car as well as over a dozen field testers. Expect huge improvements in how the rear of the car responds and feels when you eliminate the binding and friction inherent in the factory rubber upright bushings.

I contacted Mike and Juan(ManoNegra here) who work at the machine shop that offered the well received Skull and Bones KA oil adapter block Skull And Bones KA Oil Adaptor Block - Introductory Group Buy, and begged and pleaded with them to offer bargain basement Nissan pricing on more high quality machined parts. They have numerous CNC controlled machines that offer tolerances of +/- 0.0005”(that’s really tight!), and tons of machining experience. So you can thank these guys for helping make this group buy a possibility, as I’d sooner not make any parts than sell low quality junk. There are no middlemen here, so I’m passing the savings for high quality made in the USA parts onto you guys.

I’ll go ahead and apologize for the long post, but I want to start this GB off with a solid explanation of the parts involved to hopefully answer any questions you’d have. Please bear with me, and fully read through this post if you have any questions. Pricing and schedule information is at the end of the post.

The Details

There are two products here to completely replace ALL rubber bushings in your Z32 rear uprights with spherical bearings:

1. Control Arm Bearing Set – This set contains three pair(6 bearings total) to replace your camber, toe and traction arm bushings on the uprights. Includes new ½” Grade 8 bolts and lock nuts. These bearings go in the upright, not the LCA.

Each bearing can withstand a 19,875 lb load to ensure long life and reliability! Eliminate the binding/friction and huge spring effect that the small stock rubber bushings create. If you run a shortened traction arm for a better toe curve then you are surely binding up the limited movement of the stock bushings. These bearings allow for over 10 degrees of misalignment each way, and significantly reduced friction in your suspension.

NOTE: You must drill your current control arms out to ½” on the upright side. This is a very small amount of material to remove(going from 0.473” to 0.500”), and can be done with a cordless drill in about 10-15 mins total for all arms. This had to be done as high quality 12mm bearings don’t exist to fit in the stock bores of the uprights at a price anybody could afford. The new fasteners exceeds the strength of the stock hardware due to the larger size and same material strength. The new bolts and nuts use the same 19mm socket/wrench size as the stock bolts so you keep Nissan’s easy bolt-sizing scheme intact.

No modifications are needed to the upright! This is only a small amount of material removal on the ends of your camber/toe/traction arms where the bolt holding them to the upright goes.

Here are a few sleeves that have already been machined, as Juan and Mike are already hard at work on this:

2. Shock Mount Bearing Set – This set contains one pair(2 bearings) to replace the big, soft bushings that mounts the shock. This spherical bearing will eliminate the binding that is seen when using Z32 uprights on an S14 chassis due to the shock angle. Getting rid of the excess compliance and binding/friction caused by this bushing on S chassis cars will allow your rear shocks to work better and actually control the rear wheel movement without the floppy bushing letting the wheel mostly do what it wants in an uncontrolled fashion.

This bearing set utilizes your stock 12mm shock mount bolt and will work with any shock mount designed to work with the stock Z32 rubber shock mount bushing. Each shock mount bearing can withstand 47,880 lbs for an absolutely huge margin of strength and reliability.

Diagram explaining where each go:

Installation/Maintenance

These rear upright spherical bearings require you to press or cut out your stock rubber bushings and press these in. The bearings are held captive in the sleeve by a high tensile strength snap ring, and use a commonly available spherical bearing size for easy replacement in the future. These are true “race car parts,” and as such they require regular inspection, and in the unlikely event a bearing develops play you can easily go through and replace the bearings.

Pricing

For this Group Buy, I’m going to pass the savings of buying bearings and machined parts in bulk onto you guys. So everything is $10 off per set at what I’ve been able to price them before:

Control Arm Set: $290/set

Rear Shock Mount Set: $165/set

Shipping: flat $15 to lower 48 no matter how many sets are ordered

If at least 40 sets(of any combination of control arm or the shock mount sets) are sold total, I’ll give everybody an additional $10 off per set(at the time of shipping, 290/165 pricing is in effect when payment is collected). So get the word out, as this pricing is super low for this much machining and only available in large quantities. The parts are just too expensive to have them sitting on the shelf, so there will not be significant stock of these after the GB. In other words, if you want an affordable set of RUSB, go ahead and get in on the GB now.

Schedule

I’m going to take interested names and answer any questions for 3 weeks from this posting date. After this time, I’m going to lock in the GB pricing of $290 for control arm set and $165 for the rear shock mount set. Payment will be required at this point for machining to begin on the parts. Payment will be made through Paypal for ease of tracking(please include your Zilvia screen name and the RUSB sets you are ordering with the Paypal transaction). Delivery date should be approximately 6-8 weeks from there to allow enough time for machining and assembly.

Payment Required Date: Monday, July 7

Payment Instructions - Due July 7th

Paypal your calculated total for the sets you want to thedefone@yahoo.com. Remember to include your Zilvia screenname and the RUSB sets you are paying for in the Paypal subject line to help me keep track of all of this.

Pricing examples:

Control Arm + Shock Mount + Shipping to US 48 states: $290+165+15 = $470

Shock Mount + Shipping to US 48 states: $165+15 = $180

Remember, the deadline is July 7th!

Just want to be clear; the price for the Control Arms is just for the knuckle pickup points not including the Shock Mount? I'm also assuming the Lower Control Arm pickup points at subframe are not offered; Correct me if i am wrong.

Thanks

FRpilot · 06-14-2009, 03:04 PM

can you post pictures of each of the bearings in the z32 rear upright?

the control arm bushings are replacement bushings on stock arms right?

The CA bearings go in the upright to replace all the rubber bushings in upright excluding the shock mount. Using these, you can have ALL spherical bearings in the rear suspension with rod ends on all your control arms(camber, toe, traction and RLCA).

The RLCA bushings are slightly different dimensions than the upright bushings, and at the price I'd probably recommend just going with some sort of RLCA that you could adjust the roll center with as well.

The somewhat poor camera phone pic above shows the toe arm bearings and shock mount bearing. I added a diagram of the locations to help show where the bearings go. And yes, I know that's an S13 steel upright, but you get the idea.

The control arm bearings go in the upright. All these bearings go in the upright. The name just describes the location they are installed.

HOP ON THIS SHIT PEOPLE

Def, can you describe maintenance procedures a bit more? Would I need to clean the bearings with say, WD40 every so often? What sort of inspection are you referring to, visual to check for damage, or pulling it off the car and checking for play?

Thanks for doing this man.

You should just inspect them every so often as you would any teflon lined rod end/spherical bearing. Check them for play and binding, if you find any, replace the bearing/rod end. The teflon liner makes them self lubricating, so no lubrication is required. Don't spray them with anything, as that just attracts dust/grime.

Nothing that you wouldn't have to do if you had a full set of rod end arms in the rear as tons of people do now.

As you can see, the safety factor is pretty huge on these bearings, so the likelyhood of them developing significant play is very low given the loading they see.

*GSXRJJordan* · 06-14-2009, 03:48 PM

I'm so glad you've started this Def! I remember talking about it in Aron's (racepar1) thread I think... good on ya!

Not a bad price considering the cost of good bearings, and the machine work required for the sleeves! If I had Z32 uprights, I'd be in there like swimwear.

SPiG · 06-14-2009, 03:56 PM

Very excited about this. I couldn't get the money together for the first run, but hopefully we can get a big batch together.

Can't wait to be able to drive with these in.

There is a ton of machine work involved. 18 pieces in just the control arm set, and the shock mount is pretty large material so cost goes up on that end.

I know lol ~ I can get the bearings cheap enough, and thought about replacing my spindles and going spherical joints (for the reasons you listed - the rubber bushings don't allow for the necessary misalignment for proper travel/arcs), but the machine costs were too high.

For a truly badass rear suspension, this is definitely the way to go.

McCoy · 06-14-2009, 06:15 PM

I installed Def's RUSB's a few months ago and have about 2K street miles and two track days now. Well worth the money for what your getting here...

RUSB bearings as you'd receive them from Def...

Installed... I ran out of time, so just paid a local machine shop $50 to press them all in.

*Def* · 06-14-2009, 06:37 PM

Thanks for the pics Monty. Just to clarify on those, that is the v1 design which just used anerobic adhesive to hold the bearing. The new v2 RUSB will use snap rings to hold the bearings in.

Because of the misalignment issues, were you worried the suspension arms would work the bearing out? Or was it just for ease of maintenance's sake?

Seems like if it's pressed in there with some anerobic sealant, it should stay put but still be able to be pressed out? Just curious

The misalignment is pretty small, so it's almost a pure radial loading situation(not axial). The adhesive was Loctite bearing mount, which is spec'd at 600 psi shear strength on aluminum, which provides plenty of strength around the whole perimeter.

Forgot to add - a quick bit of torch action makes the bearing mount release and you can press the bearing out after that.

so would these fit in s13 uprights?

I have not tested that, as honestly, Z32 uprights are about the easiest way to save 12 lbs of unsprung weight off the car.

They use the same bushing, so I'm inclined to say yes, but it's such a small market I haven't tested it. I still have my stock uprights sitting around, so I can burn a bushing out and take a measurement.

aa87 · 06-15-2009, 10:36 AM

tempting, id have to find uprights from a junkyard and pray that pbm has some lower z32 coilover brackets

*OptionZero* · 06-15-2009, 12:44 PM

To be fair . . . doesn't the z32 e-brake assembly add back the weight savings, give or take some pounds?

You can still use stock brakes on the Z32 uprights.

*ManoNegra* · 06-15-2009, 07:37 PM

So it's finally official.
Guess we really have to make them now.

FRpilot · 06-16-2009, 12:02 AM

I let az240 know about this groupbuy since i usually see him make threads about z32 uprights and this issue.

Should fix this problem for you s14 guys. No one ever did know answer to my question though.

Z32 rear uprights on S14. Will sphericals help my problem??

Anyways, count me in for 1 set for now, but possibly a few more sets. I'm not sure yet. That's 10 sets of SM / CA combination on the list so far. Only 30 more sets to go for additional group buy discount. COME ON PEOPLE, dont' sleep on this.

The list is filling up! Whoohoo!

*Def* · 06-19-2009, 08:59 PM

Just wanted to update that there's been enough interest expressed so far to warrant further upgrades to the design(at no extra cost of course). We are going with Zinc Chromate plated 4140 Chromoly steel for the misalignment bushings/spacers. This will further increase the ruggedness of the design, since this material is very strong for this application(good thing).

Would I need to clean the bearings with say, WD40 every so often? What sort of inspection are you referring to, visual to check for damage, or pulling it off the car and checking for play? Thanks for doing this man. __________________

I remember talking about it in Aron's (racepar1) thread I think... good on ya! Not a bad price considering the cost of good bearings, and the machine work required for the sleeves! If I had Z32 uprights, I'd be in there like swimwear. __________________ TEAM SUSPECT is alive. www.JordanInnovations.com*

Just to clarify on those, that is the v1 design which just used anerobic adhesive to hold the bearing. The new v2 RUSB will use snap rings to hold the bearings in. __________________ Z32 Rear Upright Spherical Bearing Group Buy!

Just want to be clear; the price for the Control Arms is just for the knuckle pickup points not including the Shock Mount? I'm also assuming the Lower Control Arm pickup points at subframe are not offered; Correct me if i am wrong. Thanks

Well worth the money for what your getting here... RUSB bearings as you'd receive them from Def... Installed... I ran out of time, so just paid a local machine shop $50 to press them all in.

FRpilot Post Whore! Join Date: Apr 2003 Location: Fremont, CA Posts: 3,084 Trader Rating: (3)	I let az240 know about this groupbuy since i usually see him make threads about z32 uprights and this issue. Should fix this problem for you s14 guys. No one ever did know answer to my question though. Z32 rear uprights on S14. Will sphericals help my problem?? Anyways, count me in for 1 set for now, but possibly a few more sets. I'm not sure yet. That's 10 sets of SM / CA combination on the list so far. Only 30 more sets to go for additional group buy discount. COME ON PEOPLE, dont' sleep on this. 1. cheeky14 - SM 2. OptionZero - SM, CA 3. SPiG - SM, CA 4. MangoDorifto - SM, CA 5. cdlong - SM 6.

I put a few track events on them as well. Car felt much more smoother over bumps. +1 for me __________________ .25 till 3

Def Doctor Chips Join Date: Apr 2004 Location: Fort Worth, TX Posts: 1,105 Trader Rating: (0)	Just wanted to update that there's been enough interest expressed so far to warrant further upgrades to the design(at no extra cost of course). We are going with Zinc Chromate plated 4140 Chromoly steel for the misalignment bushings/spacers. This will further increase the ruggedness of the design, since this material is very strong for this application(good thing). __________________ Z32 Rear Upright Spherical Bearing Group Buy!
