i would call powertrax, i don't think their unit will fit an 02' there was a change mid year of 00' and the newer version last i knew they don't make one for yet.

 

your 4X4 didn't come stock with locking dif?

 

I have the Eaton w/ Strange gears.

 

No it did not come stock with it. On the sicker it said "Limited slip", and you definetly know the difference when driving it. More so on wet pavement as the stupid *** torque management ruins all your fun on dry pavement. Which kind of makes me want to ask... what good is torque management when all it does is limit power when you actually have good traction and does nothing for you in rain or snow. The answer I expect would be for the dealers. Less wear and tear because you cannot lay rubber at will with the Torque **** watching the power through your trans.

 

nothing on an 02' will say limited slip for a truck. it was locking differential or nothing.

 

E-bay, But I had to buy two couplers for it as it was for a 88-98, I've got around $225.00 in it. I am not sure of the P/N but if you call summit they will tell you.
