Jeep JK/JL/JT 4" Rear Bump Stop Extension Kit

Spec sheet

Collected from 1 supplier page - confirm fit with the supplier before ordering.

If you have lifted your Jeep Wrangler JK, JL, Jeep Gladiator, or changed tire sizes, you may need to limit the up travel of your rear suspension with our bump stop extensions. This extension kit will bolt into place utilizing existing holes in the factory lower bump stop pad (JK and JL only). As a rule of thumb a 3 inch kit is good for 35 inch tires, and a 4 inch kit for 37 inch tires, however this can vary depending on the aftermarket components installed on your vehicle. We always recommend flexing your suspension and measuring the length of the extension kit that is right for your Jeep. You will receive 2 bump stop extensions and all of the required installation hardware, the parts will ship bare and will need to be painted or powder coated before installation. To install these bump stop extensions on a Jeep Gladiator, you will need to mark new bolt holes on to your factory bump stop pad and drill the new holes.
