Hotchkis Sport Suspension (25116) 2015+ Ford Mustang (S550) Sport Sway Bar End-Links. Many performance minded S550 Mustang owners upgrade their cars with stiffer sway bars, but often these upgrades cause the factory end-links to fail. Experiencing this issue during our Hotchkis Sport Sway Bar testing and development, we met this challenge with our premium Sport End Links. We tested many end link combinations before finding the best solution. Our Sport End Links have high articulation THK resin ball studs for maximum range of motion, waterproof protective seals, CNC Machined Center Sections with wrench flats, and left and right hand threads for quick on car adjustment. For the optimum end link leverage length, they offer an adjustment range of approximately 8.7" - 9.3" (220mm-235mm) (Center to Center) in the front and 4.3?-4.9? (110mm-125mm) (Center to Center) in the rear and are finished in great looking gold zinc plating. For the ultimate performance handling upgrade for your S550 Mustang, we recommend installing our complete Hotchkis Sport Sway Bar package (22116) and our Sport End Links (25116). Install our premium Hotchkis Sport Adjustable End-Links and increase your Ford S550 Mustang sway bar effectiveness and end link strength.
