The Engineered Performance Limited-Slip Differential for GM FWD cars is a TRUE clutch-type, pre-loaded unit that uses two clutches and a hardened steel pre-load spring/plate assembly to effectively lock the wheels together.
During normal driving, the EP LSD is imperceptible.  It creates no added steering effort, and nearly eliminates the torque-steer associated with spirited front-wheel driving.  It eliminates the tendancy for inside wheel-spin in turns, reduces unequal front tire wear, and increases wet-traction in high-output or factory-stock FWD cars. For FWD drag racing applications, it increases traction for quick starts by providing a 50/50 torque-split to the front tires, which results in quicker and more consistent 60' times and reduced ETs.

In Auto-Cross applications, it will eliminate the inside wheel spin that kills power-out on turns without the "lock-up" associated with ratchet or worm-gear type differentials.

Avaiable for GM FWD models TH125, 440T4, 4T45E, 4T60E, 4T65E and 4T80E
