"The POWERTRAX® Grip Pro is the latest design in traction adding differential technology. It combines the smooth operation of a
limited-slip differential, with the strength of a fully machined, forged steel case. "
When you’re driving in a normal manner a positraction limited slip differential is pre-loaded and provides equal traction to both wheels.

"Advantages Of Gear-Type Spartan Helical Limited Slip Differential
The Spartan Helical
LSD limited slip differential provides smooth engagement, quiet operation, and requires no maintenance because there are no clutches to rebuild. The unit’s 10-pinion design has a strength advantage over an equivalently sized 6-pinion or 8-pinion gear-type unit because it has more points of contact and a greater surface contact area to deliver optimal load distribution. This LSD is built tough. The Spartan Helical LSD is a fully assembled unit featuring a forged 8620 grade steel case and stout 8620 alloy internals for superior durability."
