Prothane Rear Differential Bushing Kit
Add some stiffness to the rear suspension of your 05-14 Mustang with urethane upper control arm bushings to reduce flex and increase grip. This is the Upper axle bushing located in the center of the top of the axle housing & is the mounting point for the upper control arm on 2005-2014 Mustang. This bushing will help decrease wheel hop and stabilize your rear end.
When installing, the use of the outer metal sleeve is REQUIRED
Fits 2005-2014 Ford Mustang
The suspension bushings included with this part can only be lubricated with PTFE grease, also referred to as "Marine Grease". PTFE grease is a very sticky, opaque grease that is water proof and will not degrade the bushing material. If lubed properly at installation, these bushings will not need to be lubricated again. Use of any other grease on these bushings will cause the bushing to fail and any bushing warranty to be voided.
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.
