Description
If you’re running a Winters Quick Change rear end in competition, the integrity of your pinion bearing support directly impacts gear longevity and differential response under load. The WIN7307 double bearing cup distributes pinion loads across a wider surface area, reducing wear and maintaining precise gear mesh geometry through multiple heat cycles. This is the kind of foundational component that separates consistent performance from costly mid-season failures.
