I am planning on installing a 2.5 lift on my Jeep. I purchased an adjustable JKS rear track bar because I didn't want to deal with the brackets failing, etc. What length should I set the bar at for this height? Thanks

 

You need to measure how far off your axles is and then set the trackbar there is no standard length I can give you.

thanks. I will measure before and after

 

Just curious, why measure the length of the track bar at all? All that matters is that you center up the axle.

 

Just wanted a base to start from so I'm not adjusting it 50 times before I get it right.

 

Start with about a half-inch longer than stock (measuring hole to hole) and see how it looks.

 

Sounds good. I'll run a plumb line and mark the axles and frame before I lift it to have a reference point

 

Just put a straight edge vertical against the wheel and measure the gap to the fender on either side.

 

Make the new track bar the same length as the old one. Or make it a 1/2-inch longer; it really doesn't matter. Put it on. Measure the offset of the tires by (as previously posted) placing a vertical straight edge against the tire on each side and measuring to the same respective place on the fender on each side. Divide the difference between those measurements in half. Add or lengthen your trackbar, based on what you need to either move the axle left or right. That should get you extremely close. Remeasure to see if you need to do it one more time.

This job is most easily done with two people--one to put the trackbar on, the other to push the vehicle to either side to help line things up. Some folks have used a ratcheting tiedown to replace that second person and allow the vehicle to be pulled one way or the other.

Good luck!

 

Do you need to "loose" all control arms' bolts to go easy on the bushings, right?
