Now that the temps are warming up it's time to get started. We have a few minor issues to address first and then our focus will be on phase 1 of the project (the lift). We have our parts list together but wanted to get some feedback before we start buying anything. Please take a look at the list below and let us know if you see anything we may be missing. Thanks!
BDS 4-1/2" Lift
Advance Adapters SYE
Tom Woods Rear Drive Shaft
Cragar 397 Wheels
33x12.5R15 Wrangler MT/R Tires
This is one of the best posts ever:
It's great that you are doing the SYE up front - very, very nice!
Tom Woods is awesome - good choice.
I have the MT/R tires (35"), and love them - good choice.
Make sure you get the wheels with about 3.75" of backspacing. You'll need it for the 12.5" wide tires.
Some other things to think about
1) You probably don't need 4.5" of lift for 33s. I personally like to keep my COG lower - I have 35" tires, 2.5" springs and 1" body lift. There are different thoughts on this.
2) The spare tire - the weight of a 33" tire will quickly destroy the stock tailgate. But you can always carry a smaller spare.
3) Gearing - 33" tires are much larger than stock, and may cause performance issues
4) Brakes - the YJ brakes aren't great, but should be okay for 33" tires. There's not a real cost-effective upgrade for them. Maybe the double diaphragm booster upgrade.
5) Rear Dana 35 - it's a weak axle. I personally wouldn't wheel it on 33" tires, but others have and continue to do so.
6) Dana 30 front u-joints - you may want to upgrade to a one-piece passenger shaft (CAD delete), and also upgrade the driver's side at the same time to get larger u-joints.
There are a ton of threads on all these issues.
