Description
It offers increased street and trail power by optimizing the engine's RPM for mechanical energy conversion. The 4.88 gear ratio is particularly beneficial for vehicles with larger tire diameters, compensating for the increased turning radius and improving fuel economy while enhancing off-road capability. The kit includes a ring gear with 8 bolts and a 26-spline pinion.
