The Koni Yellows that I have are designed for the OEM front housings and OEM springs. They aren't the same as the race inserts. Koni part numbers: Front 8641 1364Sport, rear 8040 1226Sport.

Front shock shaft diameters, measured with a digital caliper: 21.75 mm main shaft, 13.39 mm top. Above the top section is a short taper, and then the threads for the top nut(s).

Rear shock shaft diameters: 11.75 mm main shaft, 9.91 mm top. There is a bead between the body and the top section; it's a few mm wider than the main part of the shock shaft.

Will the Vorshlag spring perches and the Tein mounts fit on these shocks?
