Want to experience precision driving, faster lap times, improved road feel and feedback?

Our patented PolyBronze suspension bearings set a new standard for performance, ride quality and ease-of-installation. Regular polyurethane/plastic suspension bushings are obsolete!

PolyBronze bearings are superior 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.

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.

  • No squeaks or binding
  • Extremely smooth ride quality
  • Easier to install than rubber bushings
  • Integrated grease fittings and grooves
  • Note – 1967 spring plate bushings changed mid-year. The following ’67 chassis numbers transitioned to the late style ’69-’89 style bushes.
    • ’67 911 from Chassis Serial Number 307 325
    • ’67 912 from Chassis Serial Number 354 938
    • ’67 911 S from Chassis Serial Number 305 101 A
  • All earlier ’67 chassis numbers use the early ’65-’66 style bushes.
  • “After 5000 miles the difference is truly amazing. I was worried about the polybronze being too harsh, why I was worried I have no clue, the suspension is now like butter, I’m now driving roads that I couldn’t even think about driving before the change.”Greg in Clovis, CA – Control Arm Service w/ PolyBronze
  • “Wow, German craftsmanship from you! What shall I say… just perfect. THANK YOU THE PARTS ARE DEFINITELY WORTH THE PRICE!”Manfred P. – QC Springplate, PolyBronze Bearings
