ProComp/ Rubicon Express Jeep JK Spacer System 2.5″ with Shock Extensions

The ProComp Rubicon Express Jeep JK Spacer Lift System 2.5 Inch is a clean and budget-friendly lift solution for 2007 through 2018 Jeep Wrangler JK and JK Unlimited owners who want 2.5 inches of front and rear lift, clearance for larger tires, and a properly supported installation without replacing the factory coils or shocks. The included shock extension brackets allow the factory shocks to be retained throughout the lift, and the kit addresses proper suspension travel with bump stop extensions and extended sway bar links. At IMM Hawaii Parts, we carry this kit for JK owners who want a practical and accessible bolt-on lift that delivers weekend trail clearance and daily driver comfort without the cost of a full coil spring replacement system.

ProComp Rubicon Express Jeep JK Spacer Lift System 2.5 Inch Retains Factory Shocks

The shock extension brackets included in this kit are what make this a genuinely practical lift solution for budget-conscious JK owners. Rather than requiring new shocks as part of the lift, these brackets reposition the factory shock mounting points to allow the existing factory shocks to continue operating within their correct travel range after the 2.5-inch lift is installed. 

This approach preserves the factory ride quality and damping character that the JK was designed with and eliminates the cost of four new shocks from the total investment. For JK owners who are satisfied with the factory ride and simply want more lift height and tire clearance, keeping the OEM shocks with properly extended brackets is the right practical choice. Customers at IMM Hawaii Parts who want a cost-effective lift for their JK regularly choose this kit for exactly that reason.

2.5 Inch Front and Rear Coil Spring Spacers for Added Ground Clearance

The 2.5-inch front and rear coil spring spacers deliver a balanced lift across both axles of the JK Wrangler, raising the front and rear by equal amounts for a level and confident stance that improves ground clearance for trail use and creates room for a meaningful tire size upgrade. The spacers install over the existing factory coil springs without replacing them, which keeps the spring rate and coil geometry working as originally designed while adding the lift height needed for larger tires and improved approach and departure angles on the trail.

Extended Sway Bar Links and Bump Stop Extensions for Proper Suspension Travel

This kit includes extended sway bar end links or sway bar relocation hardware to correct the sway bar geometry after the 2.5-inch lift is installed. Running the factory-length end links on a lifted JK creates bind that limits articulation and compromises the sway bar's ability to control body roll, so the extended links are an essential part of making this lift work correctly on the trail and on the highway. Bump stop extensions are also included to restore the correct bump stop clearance after the lift, preventing premature contact at the top of the suspension stroke and allowing the JK to use its full range of suspension travel for maximum articulation on technical terrain.

Compatible With Rubicon and Non-Rubicon JK Models

This spacer lift system is designed to work with both Rubicon and non-Rubicon JK Wrangler models covering 2007 through 2018 in both 2-door and 4-door JK Unlimited configurations. On Rubicon models, this kit retains the electronic sway bar disconnect function, which is an important compatibility feature for Rubicon owners who rely on that system for off-road use. All required hardware and brake line relocation components are included as needed for a complete installation, and a professional alignment is recommended after the lift is in place.

Clears 33 to 35 Inch Tires

This 2.5-inch spacer lift system typically clears tires from 33 to 35 inches in diameter on the JK Wrangler with the correct wheel backspacing. Achieving clearance for 35-inch tires may require minor trimming or bump stop tuning depending on the specific wheel and tire combination.
