Description
Quick-change differentials are essential for racers who need to swap gear ratios between sessions without dropping the rear end. The SCS 615 set gives you two proven ratios—4.11 and 4.33—so you can optimize for acceleration on tight courses or top-end speed on longer layouts. With 6-spline engagement and professional-grade steel construction, this system delivers the reliability required in competitive racing environments.
