The TeraFlex JK & TJ large FlexArm rubber Joint provides excellent off-road capabilities with articulation and durability. The rubber bushing provides superior vibration damping, reduces road noise, eliminates clunks, and maintains proper position for maximum articulation during travel. One of the major benefits of the rubber joint is the maintenance free aspect it provides. The high strength forged housing is CNC machined to exacting tolerances for ultimate performance and durability. Zinc plating will ensure that these tolerances are maintained and preserved for the life of the rod end. This FlexArm joint utilizes a 1-1/4” x 12 tpi. accepts a 9/16” bolt.
