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 tendency 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 availabl

Two wheel traction on dry or wet pavement! Speaking of 60' times!
While attempting a big smoky 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!
