RJ-107102-101 - JL/JT/JK Front Bump Stop Kit (2 in.)

SKU RJ-107102-101


RockJock 2 Inch Front Bump Stop Kit was specifically designed for frame mounting on all JL/JK Wrangler and Unlimited and JT Gladiator models where 2 in. of boost in bump stop spacing is a good solution for your application!
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, you are able to guarantee bump stop contact when and where you need it.
We specifically use this bump stop (and include it in) our JL and JT EcoDiesel drivetrain Suspension System Systems.
Factory yellow jounce bumpers are 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.
Spacers are CNC machined billet aluminum. Finish is clear anodize on the bump stops and zinc plating on the hardware.
