CJ-5 Rear Axle Upgrade

Hi,
I have a 1981 CJ-5 with a narrow track open model 20 axle. I am looking at upgrading my model 20 stock axle with a new G2 AMC 20 One Piece Rear Axle Kit and a PowerTrax No-Slip Traction System. Has anyone made an upgrade like this? If so how is it working for you. Any thoughts?

One more question. Could anyone direct me or tell me how to rewire the stock reverse lights so that when I put the transmission in reverse the reverse lights come on. Years ago the switch on the transmission shorted and I just unplugged them from the switch. Over the years the wires have dissapeared from the transmission. I just need to know where the wires go. I know one side goes to the the transmission switch. Thanks!!!

The one piece axle kit will serve you well. You might not like the behavior of the powertrax on the road. The Detroit soft locker or an actuated Locker (ected, ox, arb, etc...) would be better for a daily driver. These are all full case lockers and are more $$ for sure.

I'd personally spend an extra $20-$40 over what the G2 axles cost and get a set from Yukon or Superior (or Moser for a little more than that) G2 is just the rebranded Genuine Gear brand and Gen-u-whine didnt exactly have a great track record (now I'm sure 5 people will chime in about how great their Genuine stuff is). But the superior, yukon, and moser products have great track records and most people on here swear by them (myself included)

Phase One : 5.3L Vortec/4L60E, Moser axles for AMC20, Twin Stick'd Dana300 - Completed
Phase Two: Bedliner, Rollcage, Seats, BESRK Rear Bumper w/ tire swing, Soft Top, and a few other goodies - Mostly Complete
Phase Three: Waggy 44 front, Scout D44 Rear, 4.56's, ARB's (F/R) SOA with YJ Springs, 35x12.50x15 BFG MT - Not Even Close to beginning

Also a mostly rust-free 1970 Scout 800A That I'll get to start working on someday...

I am going to go ahead and spend the extra money for the Superior Axle kit. Do they come with all the seals and bearings needed? I have looked at the Detroit locker and you are right they are $$. The type of driving I do is street when in the city and since I live in the desert I do a lot of hauling a$$ down dirt and sand roads. Some sand hills and rock trails but not any large scale crawling or mudding. I only have a 2' lift and a 4cyl 151 engine so i think a detroit locker may be overkill for what i do. When you say daily driver, are you talking street or offroad use? The Jeep is also my second vehicle so i don't drive it daily.

any good 1pc axle kit will come with all the bearings needed. if you arent driving a lot on the street then go with a locker...you can probably replace your spider gears with a lunchbox locker and that'll be plenty... the 151 isnt powerful enough to justify needing a beefier locker back there. plus the lunchbox lockers (aussie, lock-rite, etc) are a lot cheaper and dont require resetting the gears
