The Suretrac Diff. is made by AP Racing. The same company as the big
kits and performance clutches.

I have AP's catalogue in front of my and I will tell you what it says;

- Excellent packaging results in a direct replacement for the open
- Proven durability on road, road simulation and race track.
- Senses torque, does not require prior wheel slip
- Operates in conventional lubricants including ATF.
- Constant performance with respect to speed, torque, and temp.
- ABS compatible
- Supplementary to, and compatible with, electronic traction control

".. The suretrac device itself sustains differential torque across
axles and directs the greatest torque to the tire with the best grip,
offering improved differential action particularly in adverse conditions
enhance handling and cornering"
" Suretrac utilizes an arrangement of opposing cams and followers which
enables the device to transmit whatever unequil torque the tire contacts
withstand, upto a torque limiting ratio set by the design"

Hope this helps you guys out,
