Daystar Rear Upper Control Arms

Daystar Poly Flex Control Arms are designed for Jeep enthusiasts by Jeep enthusiasts. Constructed of heavy-gauge tubing, these arms use a combination of Poly Flex Joints and Poly Joints to maximize suspension travel and articulation. Poly Flex Joints feature a spherical ball encased in a special blend of polyurethane. Housed in a steel outer shell, the joint allows for a greater range of control arm movement without binding in its attachment points. Unlike a traditional heim joint, the Poly Flex joint does not make noise and is completely rebuildable. At the other end, the Poly Joint features a Polyurethane bushing that is specially designed to move and deflect as the suspension articulates. Daystar's Poly Flex Control arms are also adjustable to dial in caster and driveline angles. Designed to work on suspensions with 0" to 6" of lift, the Daystar Poly Flex Control Arms are a beneficial upgrade for any off-road enthusiast.
