Description
Quick-change gear sets let you dial in your rear axle ratio between rounds without swapping the entire differential—critical for drag racing, road racing, and dyno tuning where track conditions and weight distribution demand precision. The Winters 8500 Series delivers this versatility with two proven ratio combinations (4.12 and 4.86) built from steel that withstands repeated heat cycling and shock loading. If you're running a 10-spline quick change center section, this is the multi-ratio solution that keeps you competitive across varying track conditions.
