I have an old ('84) CJ-7 that has mostly stock suspension .. .. only mod
is a single add-a-leaf on all fours. It has a mildly built 350
small-block Chev. and a Tremac T-176 4 speed. It currently has 2.73:1
gears and 33X12.5R-15 BFG's. The effective gear ratio calculates to
something like 1.92:1 .. .. not good. Since swapping gears means
changing carriers also, it's getting kinda expensive to go that route,
so I'm trying to look at all my options here. Anybody want to toss out
ideas as to what they would do with this setup if it were theirs ?? ??
?? I'm thinking 3.90:1 up to 4.10:1 ratio, preferably posi./limited
slip. What fits ?? What's best ?? What's the best compromise ??
This thing is primarily (95%) street driven. I just want it to be able
to go play when I feel like it !! !! !!

thanx .. .. ..

<<<__Bøb__>>>

 

I would do a Detroit Softlocker in the rear (they don't make the limited
slip Tuetrac for the AMC 20) and an open front with at least 4.10 or better
yet 4.56 gears. Your going to have to buy carriers anyway.

With a 350 and 33's, he will destroy an AMC 20. Upgrade it to a D44 and get
4.56's.

Actually, Rambler's 400 HP Factory Experimentals never had a
problem with their AMC-20. It's only if the axles have been taken apart
and incorrectly reassemble do they fail. AMC-20 8.75" ring to the Dana
44's 8.5". Axles: http://----------.com/dana35c/amc20dana44axles.jpg
