When the R35 first came out we rushed and made axles right away, but it seems when the cars got to about 1000HP other things started to break. Not our axles, but the inner differential stubs. The early cars never seemed to be an issue but this car is a bit heavier. This set of stubs has been designed to eliminate the conversion plate we supplied with the NI66 kits and mounts directly to the 108mm CV on the axle.The stubs are made from 300M (same stuff we have been using from Sweden) along with the billet 4340 housings will handle anything you want to put into them (these will not work with the stock axles).
Please Note: Stubs will not fit the stock axles, only the Driveshaft Shop Pro-Level kit (NI66 and NI68)
