Speedtek 10” Quick Change Differential Gearsets
Universal Fitment
Compatible with all quick change differentials using 10-spline shafts.
Versatile Ratio Selection
Our gearsets are labeled from shortest to longest ratio, based on a 33-tooth crown wheel and 8-tooth pinion (33/8 = 4.12 final drive).
Each gearset offers two usable ratios – a Low and a High – depending on how the gears are positioned in the differential.
