Urethane sway bar mount bushings deflect less for better handling. Urethane resists oil and temperature changes for longer life. Sold in pairs.
Polyurethane is an ideal material for performance suspension bushings, motor and transmission mounts. Don't get us wrong, Mustang rubber suspension bushings and mounts are a proven compromise. However, additional horsepower, plus size tires, lowered canyon carving street setups all mix with normal atmospheric conditions and undercar grit and grime to stress rubber bushings beyond design limits.
Polyurethane bushings are firm enough to control movement and maintain alignment in sway bars, control arms, and other stressed suspension components without the harshness or resonance associated with solid metal suspension bushings. We believe that after experiencing the precise steering, road feedback and the added firmness PROTHANE polyurethane bushings offer, you'll never go back to rubber bushings.
* * * NOTE- All sway bar mount bushing applications are suggested. To Verify proper fit, you must measure your sway bar before ordering! This can be accomplished by using a dial caliper or by tightening an asjustable "crescent" wrench on the sway bay and using a measuring tape/ruler to measure the distance between the jaws of the wrench.* * * .
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.
