Front Wheel Drive Positractions for GM Vehicles

When you're serious about front wheel traction! Upgrade your non positraction differential carrier to positraction.

The EP Limited Slip Differential (EP-LSD) for your GM Front wheel drive vehicle applications. This a clutch-type, pre-loaded limited slip differential that applies power to both drive wheels all the time. It is still a full-functioning differential, not a "locker" or spool, so it is totally street driveable. The EP-LSD used two sintered-bronze clutches, CNC-machined hardened-steel pre-load plates, and custom pre-load spring rates to provide unequaled front-wheel-drive traction. Transmissions include: TH125, TH125C, 3T40, 440T4, 4T60, 4T60E, 4T65E, 4T65E-HD, 4T40E, 4T45E, 4T80E, Getrag 282. The EP-LSD is available for all General Motors front wheel drive cars, vans, and SUV's including:

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 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-x 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. The EP Limited Slip Differential uses friction clutches to allow the differential gears to "grip", not slip. The EP Limited Slip Differential uses die-stamped (Street) or CNC machined (Race), hardened-steel thrust plates and specifically designed pre-load springs sets for each of the two versions available.

Two wheel traction on dry or wet pavement!  Speaking of 60' times! While attempting a big smokey burnout, we had both tires soaked in water, the e-brake set, and both rear tires chocked and the car STILL wouldn't sit still long enough for our photo-op.  It drove over the chocks and pulled straight ahead!

Here's the EP Limited-Slip Differential in a turn.  The wheels were turned hard left and both tires STILL SPIN! The competition can't claim this!  (the car was backed up to the start for illustration purposes)
