Product Description
Rock Jock Adjustable Front Bump Stop Kit (Wrangler JK, JL & Gladiator JT 2007+)
RockJock Adjustable Front Bump Stop Kit for JL/JT front as well as JK front are a completely different take on the concept of bump stops!
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 (see diagram in the photo gallery). By lowering the upper 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 in. 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 and loosen the bump stop body with the supplied spanner wrench, add or subtract bump stop shims and then tighten the assembly back up!
Factory yellow jounce bumper is retained and relocated by inserting it back into the bottom of the new aluminum RockJock bump stop body. 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.
Kit Includes:
- Two (2) bump stop spacers (upper half)
- Two (2) bump stop spacers (lower half)
- Bump stop spacer shims
- Spanner wrench
- Necessary hardware
- See diagram in the photo gallery for minimum & maximum adjusted heights
- Fits the upper bump stop cup on all factory JL, JT and JK frames
- Intended for use with 2 1/2 in. of lift and greater
- If this kit is used with other than a stock axle, the height of the bump stop pad on the aftermarket axle must be taken into account. If it’s height differs from the height of a factory bump stop pad, you must adjust this bump stop kit to accommodate the difference
- NOT for use with JT Mojave model
- JL Extreme Recon package includes factory spacers. This kit should not be stacked or used in addition to the stock spacers
- JL 392 model feature a different bump stop height than other JLs, thus this kit will require less shim than it would on a similarly equipped non-392 model
- Required spacer amounts on a JK/JKU with similar lift height, shocks, and tire/flare combinations may not be the same as a JL/JLU/JT
