These arms are used in conjunction with the RE4020 arms to convert the factory four link to a radius arm design. This change improves ride, handling, and driveline geometry in your lifted Jeep. This arm is constructed out of 2 inch x 1/4 inch wall 4130 chromoly and is nearly bulletproof. The arms are adjustable and feature our Super-Flex joints for increased axle articulation.

Q: I have a 4" procomp short arm lift on my TJ currently, will this work with it or do I have to have your product on it already? Also, can I keep my stock skid plate? Answer this question
A: This kit upgrades a 4" standard kit into a long arm kit. Its going to come with new arms and a skid plate that the arms mount to because they are longer. The long arms wont mount to the stock frame mounts they mount to the new skid plate farther back under the jeep.
