2.5" TeraFlex Budget Boost

Strongly considering purchasing one of these for my JK and 35"x12.50r15 shortly after. Should i be worried about rubbing? I also plan on replacing the bumping with this http://www.roughcountry.com/jeep-jk-...mper-1054.html . Should I add a 1.25" body lift? Some reviews on the budget boosts and your guys experiences with it would be awesome Thanks

You can clear 35's with a 2.5" BB. Shouldn't need a body lift and actually I would advise against it and strongly against one over 1".

Why would you advice against the body lift?

Ther is no need if you do the proper suspension lift. use that money you would have spent on both and get one good suspension lift that has enough clearence for the tires you want to run. I had a BB on mine with 35s and no rubbing. I am putting a BB in my New 2 door w/ 35s should not be a prob. Will post after installed if I rub but I should be ok.

JK’s don’t typically need body lifts. They can fit large tires with minimal lift with minimal trimming the larger tires you get. I guarantee you 2.5” will clear 35’s easy and if you desire more lift just change your suspension and do it right. You gain no up/down travel from a BL, just clearance for bigger tires.

Also they don’t make “gap guards” and relocation brackets for bumpers etc. for the JK. There will be a 1.25” gap between the body of your Jeep and your bumpers vs. a stock one or a suspension lifted one w/ no BL.

You can gain suspension travel from using a body lift in combination with a suspension lift. The clearance they provide for larger tires means that less bump stop is required to clear a given tire size. Reducing the amount of extended bump stop needed will increase the amount of compression which also increases the total amount of suspension travel.

When gaining tire clearance with a suspension lift alone, you must completely rely on bump stops to increase tire clearance. Suspension lift alone does not increase tire clearance. By lifting the suspension 2.5" and then installing a 2.5" bump stop to keep the tires from rubbing you eliminate all the compression you could have gained from the lift and completely eliminate 2.5" of total suspension travel. Using a body lift, flat flares, or both will decrease the amount of bump stop that is needed which increases the amount of compression and overall suspension travel.

This is also untrue. Rough country includes both a shifter correction bracket for the 6 speed to eliminate trimming and brackets to raise the rear bumper. The gap in the front isn't really noticeable, and it would be easy to hide the gap in the rear wheel well if it bothers you.
