I currently have a 79 cj-5 with the model 20 rear with 1 piece axles and its suppose to have a trac lock in it. Well the track lock is whooped. you can stop the wheel from turning with 1 finger. I am interested in a lockright, but according to the catolog, it will not work with factory traclock. Does anyone have info on this? Thanks

Yeah, It won't fit. The Trac-Lok case is not big enough, I think. You can get an open case new for about $50 or so. Too bad, I just sent my model 20 to the junk yard, It had an open case. Just remember that the 2.73 gears use a different case than any other ratio.

If you can, consider a Detroit. I know they are alot more, but it is a stronger unit. I had 3 lock-rites break on me back when they first started, but they are better now.

You should buy a new carrier for the gears you will be running. If cost is a major consideration, try a Detroit EZ locker - never broke one with 34" tires. It is a side gear locker like the lock rite - for the AMC 20 - the ez locker seems to be stronger. Someone used to make a specially heat treated carrier that was polished for stress relief for a 20 that was a bit stronger - side gear lockers exert more force on the carrier to spread "open" from side to side.

I would choose the side gear locker over the Detroit Locker unless you spent a bunch of time off road - they can be brutal on the old drivetrain on the pavement.

The lockright wont fit, but Powertrax does make their new NoSlip locker to fit into tracloc carriers. It costs about $100 more, but greatly reduces the locker probs for street driving while still being fully locked up. It is a little stronger than the LockRight as well. The worst part about the 20 is that no one makes an open carrier anymore, you have to find a used one. Good Luck.
