My plans are the 8.8 and D35 swap. I was going to put 4" coils up front and homemade lift in rear. Run 35's with fender trimming. When money allows, I would go extended radius arms and when stock tranny or engine goes out(very soon im sure) I will drop in a 302.
The axles I have are 3.73's. Do you think Ill be able to move efficiently with 35's?
I plan to join a local riding club and get into organized trail rides. I would like to be able to drive it on the road still. I have a limited slip in the rear and im going to spool the front.
you cant just throw 4inch coil in, you need a lift of some kind to correct camber in the front.ethier a drop bracket kit, or cut and turned beams like I have.(cheap plug here"I have anouther pair of dana35 cut and turn beams sitting here on a shelf passenger side beams renforced etc")
and if you want to keep the stock stubby radius arm to let the wallet recover you will need some radius arm drop brackets as well to correct the caster. no caster= sterring on marbles.
3.73's and the 302 if your going to run a c-4 or c-6 wont be to bad with 33's
35's would be bettter off wiht 4;10's at the least if not 4.56's.
unless you purpose build a 302 to have gobs of torque right off idle to about 2400rpm tehn 3.73's and 35 could get along but you would want trun a good tranny cooler with a fan.....tranny cooler with a fan would not be a bad ideal anyway I would think on a trail truck.
for a trail truck, the chevy leafs seem to work good for people alot of flex and give 5inches iof lift I belive.
Im not a fan of posi's exept in street cars and daily driver type of trucks or a budget built desert truck(only cause jumping and skipping whoops puts alot of snap shock on little axle shafts and possibly getting stuck is alot better than a broken axle shaft in the middle of baja) that are nearly stock. Id suggest a locker over the posi in the rear for a trail truck.
If it wasnt for the 8.8 being a c-clip axle Id say spool it even.unless you drive on ice alot.then a spool may get a little scary..I dont know, I live in san diego....snow and ice dont happen much here.And when it dose I kinda seek out the ice to have a little whoo hooo fun..
the front I would not spool.the hubs on these trucks are a bit weak,like to explode the housings with just lockers.and a locker gives youa little slip vs a spool when trying to turn as well...
So Id locker it front and rear...or if your cheap weld the rear maybe.
