The critical importance of a genuine SADEV crown wheel for your 11/52 ratio
In motorsport, the final drive is the last link that transforms engine RPM into pure speed. Using a low-quality or worn crown wheel on your SADEV ST66 gearbox means risking gear tooth failure under heavy load, which leads to the immediate destruction of your gears and differential. Without the precision-cut teeth of the SADEV 52-tooth crown wheel, you lose reliability and mechanical efficiency, compromising your performance on the track or stage.

Technical FAQ
Why replace the crown wheel during an overhaul?
The 52-tooth crown wheel works as a matched pair with its pinion. Even microscopic wear changes the contact patch. Failing to replace a marked crown wheel can lead to excessive gear whine and, eventually, a clean snap of the teeth due to metal fatigue.
Does installation require specific tools?
Installing a differential crown wheel on an ST66 requires precise shimming and strict adherence to torque specifications. Improper assembly will negate the benefits of your engine preparation and could lead to catastrophic failure.
