SADEV Splined Hub for Renault Clio 3 Cup Input Shaft

Why a worn splined hub can condemn your SADEV gearbox?

The splined hub is a precision component that ensures the mechanical connection at the end of the input shaft. By ignoring the wear or marking on your current hub's splines, you accept a progressive degradation in shift quality. A defective hub causes mechanical play that eventually damages the gears and, in the most severe cases, snaps the input shaft of your ST75-14 gearbox. Without replacing it with a genuine SADEV part, you expose your Clio 3 Cup to a major failure in the heat of competition.
