Default Coil hits bumpstop cup

Passenger side coil hits bumpstop cup. How can I do anything about this? I havn't gotten anything aligned after the lift, would that help? Also I used the fixed arms that came with the lift.

Need more info. what kind of lift how big? what do you have for track bar? yes alignment would probably help but Adjustable arms would also help with *caster and pushing the axle forward. As you lift the jeep the axle moves towards the rear of the vehicle. to fix this you run longer control arms. the other thing you can do is a grind down the lip on the bump stop cup.

There's your problem. Longer lower arms will move the front axle back where it belongs.

Another thing you can do that could help a tiny bit is shim the lower arms. There is about 3/4 inch adjustment but they are Probly already shimed and if you have fixed uppers it will lessen caster

If its hitting the side, you need an adjustable track bar. If its hitting front and rear, you need longer lower control arms, and i would still advise you to get a adj track bar so you can get your axle back to center.

I already have an adjustable track bar, it hitting on the front, so yeah, adjustable arms in the near future

alignment first and make sure the track bar is adjusted right . if it's only rubbing on 1 side something's gotta be off or tweaked. Measure the control arm lengths and make sure the axle is centered in the wheel well
