***Due to inconsistent quality issues, I no longer carry the 8.75" True Trac. Please consider the 6 helical gear Sure-Trac***
8.75" Eaton True-Trac fits all 8.75" castings all ratios and all stock axles.
Worm gear style traction differential locks up hard on dry pavement and operates super smoothly around turns. This unit does not require special friction modifier additive mixed with the gear lube. **When using stock adjustable wheel bearings, customer must insert differential thrust block (included) through the side gear splines before installing the third-member.
