ditch the body lift. SOA will clear 37s without it. You don't need it to fit the tires, you don't need it to fit the drivetrain. Anyone who that tells you a 3" body lift is necessary for an engine swap has no business doing engine swaps.
ditch the manual. I thought about it and can't determine a reason to run one over an automatic. It does not work better in the woods, and it won't stoplight race faster than an automatic. In addition they are more expensive to buy and more expensive to make work in a 4x4 behind a Gen III V8. There are very good reasons why GM no longer puts manual transmissions in their trucks.
learn to fab or be ready to pay big $$$ to someone else who can.
disregard that abomination a few pictures above. It's a show piece designed to get ooohhss and aaaahhhhsss from the general public who doesn't know any better. Waste of an LS9, waste of a bunch of other good parts.
Hey, what's the deal with the stock D44 axles? Everyone on here states they will not support anything larger then 35's without breaking even using the stock 190HP motor. They also say that even stock 60's won't support anything over 37's with a 190hp motor on open diffs.
Then the Jeep team rolls out with the new Lower Forty jeep with 390HP AND 44 inch tires WITH lockers useing a.... get this.... DANA 44 IN FRONT!!!?? According to consensus on the forum 60's could never support 44's let alone with LOCKERS and 390 HP! You would expect from what you read on the forum that the jeep lower forty would almost instantly snap the front axle the first time the power was applied offroad but the jeep performance engineers seem to disagree. Am I missing something?
You really need to search more, I run a stock 4.0 and 39's with a 60/14 bolt, stock axle's and broke a stub over the summer. Thats from a 20 year old axle and years of abuse.
1 ton yj last I knew he's still running stock inners in his chevy 60 and heck last I knew they were Neck down 60 shafts. Point is ya you can run 44" tire's on dana 44's and crouse around town, would I do it hell no. Its to much tire for such little breaks and ball joints.
The mall crawler Jeep lower forty doe's car shows and promo show's, those axle's would not last past the first rock outcrop with that much power and tire, so to the Jeep performance engineers they did there job right, built for all show and no go.
1993 YJ 4.0 60 Front, Rear steer 60, bolth spooled, 5.38's, 700r/241 39.5 iroks and beating it like it owes me money.
yes i am running stock 35 spline inners with spicer joints, 35 spline 4130 outers and drive slugs. been running this for 4 seasons, and this past season with Maxxis stickies. I got 2 seasons out of my stock 30 spline outers before breaking them
