Eaton limited slip differentials like the Posi and Detroit Locker dominate the performance market as the choice of professional racers in NASCAR, NHRA, IHRA, CORR, NMRA, NMCA and other racing associations.

Off-road enthusiasts, rock crawlers, trail riders and ATV buffs also crave the superior traction that the complete line of performance differentials provides. A heavy-duty product line of “apex” differentials built exclusively for military vehicles, construction equipment, heavy hauling, forestry and agricultural vehicles attests to the inherent strength and high quality of Eaton's entire line of premium differentials.

Beyond the rigors of every day competition, all differentials are proven and validated at Eaton's Proving Grounds in Marshall, Michigan, where it has complete testing facilities and on-road/off-road test tracks. Locker or limited slip differentials? Clutch or gear style? Automatic or electronic? Only Eaton offers them all.
