I've got a '93 Wrangler, stock I6, auto tranny and stock transfer,@ 9" of lift between body/ springs and shackles, 37 IROKS, 4.88 gears and locked rear, just one serious weak link, the 4.88's and locker are in the stock axles! LOL, but presently working on upgrading to HP dana 60 front and LPdana 60 rear from '79 f-350, so all should be pretty stout when finished, lol. Future upgrades will be chevy 350 TBI and I am "torn" between building a strong reliable TF 727 or just doing the 700r4 thing and giving up drive line length? still undecided on that part.
