RockJock Adjustable Front Bump Stops for JL/JT front as well as JK front are a completely different take on the concept of bump stops! So unique in fact that they were awarded SEMA's 2023 Best New Off-Road/4-Wheel Drive Product of the year! In high articulation situations, an axle housing mounted bump stop ends up rotating inward toward the center of the vehicle, often missing the upper bump stop entirely.

By lowering the front bump stop, and being able to adjust it’s length, you are able to guarantee bump stop contact when and where you need it. Our adjustable kit features billet aluminum components and 5/16 inch thick steel shims that are able to be added and subtracted for fine tuning, while the bump stop assemblies are on the vehicle.

You simply put a socket on the upper bolt to hold it in place, loosen the bump stop body with the supplied spanner wrench, add or subtract bump stop shims as needed and then tighten the assembly back up!

The vehicle's factory yellow bump stop cushions are retained and relocated by inserting them back into the bottom of the new aluminum RockJock bump stop bodies. This provides factory feel when the bump stops make contact.

Finish is clear anodize on the aluminum and zinc plating on the spacers and bolts.
