This 19-1716-BL Prothane ball joint dust boot set for 1979-93 Mustang contains 2 sets of dust boots. One larger set that work great on 1984-1986 Mustang SVO, & one smaller set that work great on all other 1979-1993 Mustang. They are constructed of black polyurethane for stock type looks & excellent performance.
Mustang ball joints are greatly affected by dirt, moisture and other elements. It is this reason why Prothane urethane joint dust boots are a must have. Protect this essential suspension component!
Lifted or lowered suspensions, increases in horsepower, plus-size wheels and tires can subject traditional rubber suspension bushings to forces beyond their limits. Control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks all control movement and maintain alignment but the rubber bushings they use are designed for more "middle of the road" use. Rubber also deteriorates over time, further reducing control. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane bushings can correct these conditions, and improve drivability in your Mustang or Ford Lightning.
