Product details
RockJock Front Upper Bump Stops for JL Wrangler and JT Gladiator EcoDiesel engine models are a completely different take on bump stops! In high articulation situations, tradtional axle housing mounted bump stops end 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, you are able to guarantee bump stop contact with the bump stop pad on the axle. The vehicles factory yellow jounce bumpers are retained and relocated by reinserting 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. Bump Stop Kit; Bump Stop Kit
