    Eaton Posi prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases, clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel. Eaton Posi units are rebuildable.

    Muscle cars, hot rods and mild off-road vehicles should look to Eaton's limited-slip differential for their traction answers. And the fact is, Eaton's Posi units are virtually bulletproof.

    Eaton Posi Differential Kits Include:
  • Eaton 12-Bolt Car Posi Unit
  • JEGS Differential Installation Kit
  • Lucas Heavy Duty Gear Oil (2 Quarts)
  • Richmond Gear GM 12-Bolt Ring & Pinion Set

    Note: Please read the more details section as some differentials require special bearings which are not included.

    JEGS Easy Kits are designed by JEGS Professionals to assist your shopping experience.

    19557-010 - Eaton Posi Differentials is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Bigger and tougher where it counts. Impressed to see more material in the case and flange areas, much more than the stock GM unit it is replacing. This Eaton unit actually cost less than rebuilding the GM case that needed everything, spiders, side gears, plates & discs, cross pin and retaining bolt, plus the mounting flange for the ring gear had wear from a loose ring gear. So I choose the Eaton unit for its cost and the Eaton name, once I opened the package I was impressed with the overall quality. I did not read the details closely, the carrier bearings are also a different size from stock, I was able to source them locally the day I installed it. Great unit!
