    Auburn Gear 542099 - Auburn Gear HP Differentials Details

    GM 8.2''

    Applications: Buick, Olds, Pontiac with 8.2'' ring gear. Non ''C'' lock axle-27 tooth pinion spline. Will not fit ''O'' axle with 12-bolt cover and 10-bolt ring gear.

    Techical Notes: Differential bearings provided with this differential, p/n 109-542099. Stock bearings are usually LM603049/LM603012 for the ring gear side and LM501349/LM501314 for the opposite side. Some use LM501349/LM501314 for both sides. The Auburn limited-slip differential will fit in either application. They supply 2 sets of LM102949/LM102911. Axles that have the LM603049/LM603012 bearing will still use that bearing, but the opposite side will require the LM102949/LM102911 that is included with the differential.

    Put More Power to the Pavement!

    Auburn Gear High Performance (HP) Differentials outperform all competitors in terms of torque bias... only Auburn's Pro Series provides more torque bias. Torque bias is the ability of any limited slip differential to transfer torque from the low traction wheel to the high traction wheel. It is Auburn's unique cone clutch arrangement that provides the mechanical advantage over plate or gear type limited slip differentials. Features 1-Year Warranty and 4-Year Replacement/Exchange. Made in the USA.
