SPRING PLATE BUSHING

Our patent pending PolyBronze suspension bearings set a new standard for performance, ride quality and ease-of -installation. Regular polyurethaneplastic suspension bushings are obsolete!
PolyBronze is a precision bronze bearing encased in a polyurethane jacket. The combination delivers a smooth-ride with the extreme performance of a metal bearing.
PolyBronze bearings offer an excellent alternative to plastic bushing alternatives, here's why -
Suspension mounts are coarse sheet metal pressings. They tend to be out-of-round and have irregularities that deform ordinary polyurethane bushings, pinching and binding the friction surface. Polyurethane is "grippy" with an inherently high coefficient of friction and combined with pinching polyurethane bushings create a lot of friction. The result is a harsh ride and reduced tire adhesion.
PolyBronze have a rigid bronze bearing core that does not deform. The polyurethane jacket absorbs mount irregularities while the bronze inner bearing remains true, providing a free-moving machined-fit that rides on a precision race. Provided grease fittings make re-lubrication a breeze and a figure 8 groove keeps grease in place.
The combination delivers zero squeaks and friction-free suspension movement. Well suited to street or track, ride quality is smooth and performance maximized. PolyBronze bearings replace compressible factory rubber bushings.
