Better Traction Off-Road or On the Trail.

For a distinct advantage off-road or on the track, count on Spicer performance spools for the ultimate in traction. Spicer spools keep the left and right axles spinning together, so you get constant traction and peak performance that lasts.

Spicer performance spools offer tremendous advantages for racing enthusiasts and hardcore off-roaders, providing features and benefits that standard differentials cannot offer. Spicer performance spools replace the need for a differential case, thus eliminating failures from high-torque, high-impact situations.
