The EP
Limited Slip Differential
(Patent
Pending)
Beware of imitators!
High performance LIMITED-SLIP DIFFERENTIAL for GM FWD
cars.
Immediately available for most GM FWD automatic and manual
transmissions.
Applications include:
- Hydramatic 125 3-speed
- 440T4
- 4T40/45/60/60E/65E/65E-HD 4-speed
- Getrag 282 5-speed
- Isuzu 5-speed/Muncie 4-speed coming Summer 2004
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 front 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 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. |

Pontiac Grand Prix GTP Daytona Pace Car. 3.8 SC, 3.4" pulley, SLP
ram air. Stock ECU. |
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!

There are TWO
versions of the Engineered Performance Limited Slip Differential:
The STREET VERSION is for cars which primarily drive on the street and
see very limited track use (once or twice a year for exhibition).
The RACE VERSION is for any car which sees regular track time and runs
drag radials or slicks, even if it is a daily driver.
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.
