      Boost Your Off-Road Capabilities. Boost your lifted Wrangler JK’s facilities for off-roading with the Rancho Adjustable Rear Upper Control Arms for 2 to 4-Inch Lift. These rear upper control arms are designed to work with your Jeep’s 2 to 4 inches of lift, adjusting caster and pinion angle so that these are optimized for your new ride height. The result is better articulation, particularly when going over uneven terrain. What’s more, these control arms utilize specially designed D2 bushings. These self-centering bushings require no grease and offer excellent articulation and vibration damping for improved ride quality on the highway.

      Adjustable Design. These rear upper control arms feature an adjustable design. This allows you to fine-tune your Jeep’s suspension geometry, enabling these to work with between 2 to 4 inches of lift. This way you get the best driving feel relative to your style.

      Wear-Resistant Build Quality. These rear upper control arms are manufactured from high-grade drawn over mandrel (DOM) tubular steel measuring 1.25 inches wide and with 0.188-inch thick walls. These factors offer exceptional strength and an exact fit. Meanwhile, their ends feature a forged construction for added rigidity. Finally, these upper control arms are finished in a black powder coating for superior corrosion protection.

      Straightforward Install Procedure. These adjustable rear control arms install into your Jeep’s factory rear upper control arm locations. No drilling or other modifications are necessary for most applications. Additionally, standard hand tools are all you need to complete the installation.

      Backed by a Limited Lifetime Warranty. The Rancho Adjustable Rear Upper Control Arms is backed by a limited lifetime warranty covering manufacturing defects. Please visit the manufacturer’s website for more details.

      Application. The Rancho Adjustable Rear Upper Control Arms for 2 to 4-Inch Lift fits all 2007 to 2018 Jeep Wrangler JK models.
