good and bads on gm 12 bolt

[strangeKowboy]

Just picked up a couple axels from a buddy and one is a GM 12 bolt rear. Just curious what people think of them. I have a cj7 with the amc 20 now but want to udgrade to a wider stance. The biggest tire i will be running is a 37 and i am not hardcore offroading it for a few more years. So yea let me know what ya think

The bad is that there's nothing good about a 12 Bolt. Really, they break with 35's on them and they are c-clip axles, so the shafts come out if you break one. The shafts are the same size as a 10 Bolt. IMO it's not an upgrade over an AMC 20... and an AMC 20 isn't that great.

My experience is that gm puts a little grenade inside every one. I had one built a few years back and pulled it off the trailer with no miles on it and kaboom, parts everywhere. This would be the third time i had seen it happen( not on the same rig).

Why not a 14b? find one in a van or C&C and there only 62.75" wms to wms?

Got a buddy thats been running a 12 bolt for about 7-8 years now with 38" swamps and has never broken it!

All bad, no good....Just a 10 bolt with a bigger r/p. We all know how I feel about 8.8's, but I'd run a 8.8 LONG before a 12 bolt!!!!!!!!!!!!!!!!!!!
