(1) set Polyurethane Sub-frame bushings
Prothane IRS Subframe Bushings
With Prothane's polyurethane sub-frame bushings, you can drastically improve your ride in just a few hours. One of the best and most cost-effective ways to improve the handling and feel of your pride and joy is to replace those mushy and worn-out sub-frame bushings. These high-quality polyurethane bushings not only outperform even new OE rubber bushings, but they last much longer and are less prone to deteriorate. They give you extra rigidity for excellent handling, yet are forgiving enough for those long hauls.

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.
