Description
Powerflex Steering Column Support Bearing Bushings (PFF57-405) for 1965–1989 Porsche 911.
Function and design
A steering or locating-link bushing controls movement at the specified connection. The exact location determines whether it supports a steering assembly or locates an associated suspension link.
What to consider
Match inner versus outer and front versus rear positions carefully. A bushing for a rack mounting point is not interchangeable with a suspension tie-rod or track-rod mounting bushing.
Application
1965–1989 Porsche 911.
Choose your series
- Street: the road-oriented series; compound selection depends on the individual application.
- Black Series: the firmer series generally intended to prioritize movement control. Product-specific fitment and intended-use restrictions still apply.
