I'm a newby looking for info.
I'm looking for input , but generally accepted knowledge not "well I run this and its fine "......
Let me know if this is close......
This is a general rule of thumb list for those looking for basic Tire vs lift info.
On Jeeps used for general DD and regular offroad use..
30" tires and under
May get some tire rub while turning , Add washers to bump stops as needed.
Stock suspension OK , may rub (You can trim the plastic fender extensions.)
Or a Budget Boost lift (2"front 1" back) all the way up two up to a 3" lift.
A front lunchbox locker is a good option on Dana 30 ( Lunchbox = uses existing differential carrier housing.)
BUT a rear Locker may or may not be OK on Dana 35 ... Debatable .... Juries out ...
Most TJs have Dana 30 front Dana 35 rear.
( NOTE Rubicons have Dana 44 front rear with selectable lockers and SYE .)
Stock suspension with flat tube fender kit.
OR 2.5" to 4" lift .
Getting into tire rubbing may need wheel spacers or offset rims or bump stop mod.
Drive shaft work needed for any lift over 3" and SYE = ( Slip Yoke Eliminator) (Rubicons have SYE stock).
Because of steering geometry issues your getting into Tie rod , Drag Link , Track bar upgrades.
Adjustable short arm upgrade is a good idea. Again for steering and for strength .
A front locker is still a good option.
At this point rear Lockers are Probably a bad Idea , may need to upgrade axles.
Re-gearing is almost mandatory .
???"lift with flat fenders
A 4.5" lift may need fender trim
Or 5" to 6" lift .
Now you NEED Drive shafts , SYE , Brake upgrade , Brake lines , Long arm kit , Tie rod , Drag Link , Track bar upgrades.
I'm not sure about front lockers on Dana 30 with 35" tires.???
Defiantly NO lockers on the Dana 35 with 35"tires
Any thing above 35" tires is hard core land and you should have enough experience to know what you need or Don't do it....
