JeePerf CONTROL Shock Absorber Bushings Re-engineered for Control, Comfort And Responsive Steering If your vehicle is suffering from early tire wear, poor handling, or loud noises under the chassis, you could be dealing with worn out suspension bushings. Designed to attach the shock absorber to the vehicle, those bushings become an essential components of your handling and steering systems. The bushings also serve a second duty to absorb impacts from the road, smoothing and quieting out your ride. The material used to absorb impact and vibrations in OEM bushings is rubber which served the automotive industry for well over 80 years. With age, however, rubber loses its natural oils due to the elements, causing it to harden up, dry rot, crack and sag under the weight of the vehicle. It will lose its ability to absorb impacts and vibrations, and it will sag throwing off your suspension geometry and wheel alignment. When this happens, you start hearing more of the road noises, feeling more of its impacts, losing your ability to steer the vehicle as was intended and wear out your front tires. LONG-TERM PERFORMANCE At JeePerf, we HAND build each bushing to far exceed OE specifications by a wide margin. Using space age materials, we build our bushings for longevity, comfort, low-to-no maintenance requirements, precise steering and perfect fit. While the OE bushings might sag or rot away, our control arm bushings will have a very long service life. Why use JeePerf bushings? We build our bushings to achieve special design targets. They need to have a precise fit, very long, reliable service life, a steady, non-degradable performance throughout their service life, and to have better value than OEM offerings. In order to achieve that we decided to: - Use soft, specially treated, permanently lubricated, Polyurethane to provide a quiet, comfortable yet very well controlled ride. Our polyurethane compound is proprietarily treated to provide most qualities of rubber, yet have the famous long service life of polyurethane. - Use a fully floating bushing design so it will maintain a fluid, resistance free, non-binding, full range of motion. Think of our bushings as vibration dampening bearings. - Use chromoly pins to provide extremely solid engagement and reinforcement to the control arm and a solid mount to the vehicle. - Use a solid lubricant to maintain a smooth, fluid bearing like motion of the bushing without the need for regular lubrication. We believe we achieved our design goals with this design and believe you will be impressed with the results. We spared no expense designing and building these bushings which are hand built using the very best materials available. Built by enthusiasts, for enthusiasts, we invite you to consider them when ready to UPGRADE your suspension. Note: Will fit models Sebring, Mistral, Quattroporte I, Mexico, Ghibli, Indy, Khamsin Can also be fitted to the Bora & Merak, however these applications require that the ID of the bushing be reamed to 12mm.
