How much lift in the rear for RC 3.5 lift kit for JT?

[Top_papi]

Hi guys,

I installed a 3.5 rc lift on my 2023 Gladiator sport s and I am now fixing the weaknesses in that particular lift. One of the weaknesses imp is that the rear does not come with a rear adjustable track bar or bracket. It is recommended to install an adjustable track bar for a lift that is more than 2 inches. The lift raises the truck 3.5 in the front but I don’t how much the rear is lifted. The vehicle from the factory had a rake, I’m not sure how much, but with the lift the truck is leveled. I want to know how much the rear tire a lifted on the rc lift kit to know if I should purchase an adjustable track bar.

Doubt you'll get an accurate answer to the amount of lift. I have a 3.5" on my JTM and it has settled at 4.0". Depends on how much weight you have added or not. Many lift heights are assuming you'll be adding a lot of bumper/winch/armor/bed rack stuff. You also didn't say whether it was the 3.5" spring kit or the spacer kit. That could affect your final lift height as well.

If you have your front track bar adjusted correctly so that your front tires are even with the body, side-to-side, then look down from the front at the passenger and driver side rear tires. The rear axle has likely been pushed to the passenger side after the lift. You might be able to correct with a rear TB relocation bracket. Depending on how much lift you actually get out of the 3.5", you may need an adjustable TB. Or you may want both. I have a 2006 Rubicon with a 2.5" RK lift, with no rear axle adjustment (stock TB). When I hit a big enough bump at speed, it shoves the rear body to the passenger side enough to where you really feel it.

You can hopefully get a few of the more learned folks on here to tell you any implications by have a rear axle not aligned with the front (side-to-side).

Get a level, put it on the side of a rear tire, plumb the level and measure to the outside of the rear fender flare. Repeat the process on the other side.

If the numbers are within 1/2" of each other, just drive.

If the numbers are greater than 1/2" of each other up to about 1-1/4" get a relocation bracket.

If more than 1-1/2" get an adjustable rear track bar.

Keep in mind, even just driving on the street your axle will travel a little side to side. So if you're totally OCD-AR you'll never be satisfied.
