    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.

    Rated 5 out of 5 by from Can't review this yet. I would like to properly review this differential, but I am still waiting on axle bearings I ordered a month ago. So once those show up and I get this installed I may revisit this review.
