Description
If you’re running a quick-change rear end on the track, gear ratio selection directly impacts your launch characteristics, top-end capability, and overall ET. The Winters 8522 gives you two proven ratios in a single, precision-engineered steel package—swap between 4.12 and 4.86 setups without breaking down your entire differential. Built for serious racers who demand durability under repeated high-load cycles.
Each gear set is constructed from high-quality steel and manufactured to Winters’ exacting tolerances, ensuring consistent performance across multiple race weekends. The 19/25 tooth configuration paired with dual ratios makes this kit ideal for bracket racing, circle track, or any application where you need quick adaptability without sacrificing reliability.
