drive shaft angle after lift

[buck119fa]

Anyone running a 3 to 4 inch lift tell me what your drive shaft angel is after the lift and how it's running with that angle. did you shim the axle or drop the rear of the trans or ???
Looking at the angle on mine and wondering what everyone else has and if there have been any issues with it.

Depends on the driveshaft you are running? With that amount of rear lift is may be possible just to shim the rear end and attempt to create equal angles at the rear end and transfer case. Although Once my rear was lifted higher than 4" I needed a dual cardan shaft and angled the rear end directly to the transfer case.

I had about 5" of lift on a BII and needed a double cardan shaft. The front shafts from the 1354 Rangers/Explorers work great for this and are plentiful in wrecking yards, though they need to be shortened an inch or so.

I had a 6" lift on my old B2 with an Explorer front shaft (I think) could have been an early B2 rear shaft, either way, my pinion angle was fine and my lift consisted of 4 door Explorer springs, 2" blocks, and Belltech shackles.

If you do need to shim the springs, DO NOT use aluminum shims! They will crack and about 1/3 of the shim will fall out. Myself and a bunch of other local guys have had this issue. Skyjacker springs are especially prone to this because they all come with aluminum shims! The fix is either steel shims or cut your perches off and turn the axle, then weld them back on. FYI, words from the wise

I have a 5" lift on my choptop. I want to say the rear shaft is supposed to be a Tom Woods shaft for lifted BIIs. Shaft came with the one parts truck I got. I did Explorer leafs with an extra leaf and extended shackles in the rear with no shim. Seems to work just fine.

thanks for the info, I'm replacing the axle this winter and have to get new perches welded on anyway so just checking for that angle, if I have weld I might as well get the angle right without shims and such

A good way to set your pinion angle is put everything together WITHOUT welding the perches on. Snug up the u-bolts, attach driveline, then put a floor jack under the pinion yoke on the axle and jack up while you measure angles on the t-case and pinion yokes with an angle finder. Tack the perches on, disassemble, fully weld and paint. FYI
