Porsche 911 Control Arm Rebuild Service

"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


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
  • • Smooth ride quality
  • • Easy installation
  • • Integral Grease fittings and grooves

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.

Porsche 912 Polybronze Bushings & Bearings

"Hi Chuck, I've been running with the new suspension for about 2 months now and am completely in love with how it changed the car! You were right; my concerns about increased harshness from the Polybronze bushings and dampers was completely unfounded."
