Rancho 07-17 Jeep Wrangler Fr and R Short Arm Suspension System Component - Box One

Rancho is known for making tough suspension parts that hold up to serious off-road use. This component, Box One of a three-box master kit, is for the 2007-2017 Jeep Wrangler JK and is designed to give you a significant boost in ground clearance and wheel travel. If you're looking to tackle tougher trails or just want your Jeep to sit higher and handle better both on and off the pavement, this kit is a solid choice.

This part of the kit includes front and rear progressive rate coil springs that are tuned for a good balance of on-road comfort and off-road performance. You also get adjustable upper and lower control arms, which are crucial for properly aligning your Jeep after a lift. These arms feature Rancho's D2 high-articulation bushings. They're designed to be maintenance-free and allow the control arm sleeve to rotate smoothly within the bushing, which helps reduce wear over time. The kit also comes with adjustable front and rear track bars to keep your axles centered under the Jeep, extended sway bar end links, and bump stop spacers. Everything is fabricated from high-strength, low-alloy steel with a bolt-on design, making installation more straightforward.

This specific box, RS66114B-1, is just one part of the complete RS66114B master kit. You'll need to order boxes RS66114B-2 and RS66114B-3 to have all the components for the full 4-inch lift. Keep in mind that for 2012-2018 models, you'll need an exhaust crossover pipe (either Rancho RS720003 or DynoMax 88347) if you're not replacing the front driveshaft. This kit is designed to fit up to 37-inch tires, giving you the clearance needed for serious trail riding. It also complies with NHTSA FMVSS126 standards.
