The amount of force exerted on the sway bar end link is staggering?especially if you?ve upgraded to an aftermarket sway bar, like BMR Suspension's SB045. The stock end links are weak and can bend or break. BMR?s ELK014 end link kit allows you to push your S550 Mustang to the limit without fear of end link deflection. BMR manufactures the ELK014s out of heavy-duty steel hex bar stock. The right and left hand threaded ball joint-style tie rods are manufactured by Proforged and offer huge advantages over other companies? end links that use rod ends. Ball joints allow for more articulation than a rod end, which is what you want when you hit the track. BMR?s ball joints are greasable, which you won?t find on our competitor?s end links. This ensures long life and flawless operation, and they make less noise than rod ends. The ball joints attach to the sway bar with 12mm studs, while the ball joints attach to the end link tubes with ?-inch studs. This combination of components gives you a huge increase in strength over stock end links.
