Description
Powerflex Rear Trailing Arm Support Plate Bushings for 1965–1967 Porsche 911.
Function and design
A suspension arm bushing forms a controlled mounting point between the arm and its supporting structure. Compliance at that joint allows movement under load; the condition and construction of the bushing influence how consistently the arm locates the wheel.
What to consider
For a suspension refresh, replacing deteriorated mounting bushings addresses movement at the joint rather than changing the spring or damper rate. Final steering and handling behavior also depends on the remaining joints, tires and alignment.
Application
1965–1967 Porsche 911.
