Re: 93 YJ rear end
I do want to add a locker of some type - this is a daily driver (90%) but
when I go off-road I would prefer having the confidence of a tight rear end. I've spoke with 2 shops and they both are recommending higher gears and posi-trac for about $2,000 - does this sound reasonable? thanks jaco "SoK66" <SoK66@frontier.net> wrote in message news:d1qlrb063a@enews3.newsguy.com... > > > Most manual trans 4.0L YJs came with 3.07s.

For my money I wouldn't spend a nickel on a Dana 35 rear end. Money is much better spent on a salvaged TJ D44, which you can easily adapt by cutting off the spring buckets & trailing arm tabs & installing spring pads for the YJs leaf springs. Add gears & a locker and you're rear end hassles are over up to 35" tires. If you must keep the D35, look into one of the Super 35 kits. These have Detroit Lockers which can be a handful if you're planning it to be primarily a street vehicle. |

Re: 93 YJ rear end
I have very limited knowledge of rear ends,,,,,
So you're saying that the 35 even geared up may not be sufficient,,, is the difference between a 35 and 44 axle diameter? thanks again jaco "SoK66" <SoK66@frontier.net> wrote in message news:d1qr5h02a0l@enews1.newsguy.com... > > "jaco" <jaco@wi.rr.com> wrote in message > news:6K50e.12621$gx3.7176@tornado.rdc-kc.rr.com... >>I do want to add a locker of some type - this is a daily driver (90%) but >>when I go off-road I would prefer having the confidence of a tight rear >>end. >> >> I've spoke with 2 shops and they both are recommending higher gears and >> posi-trac for about $2,000 - does this sound reasonable? >> > > It depends.
