Product details
Replace the inner front control-arm bushes on the specified classic Porsche 911 and 914 arms with Powerflex polyurethane. The Street and Heritage options use the same application-specific polyurethane specification; Heritage changes the appearance to dark grey for a more original-looking installation.
Technical Details
- Street reference: PFF57-401; Heritage reference: PFF57-401H.
- Position: front control-arm/wishbone inner pivots.
- Four bushes are used per car; the set covers this location on both front arms.
- Referenced original arms: 91134190100 and 91134190200.
- Polyurethane replaces the rubber bushing at the specified pivot location.
Fitment & Compatibility
Powerflex lists this bushing family for 911 models from 1969–1989 and 914 models, including the 1970–1976 914 application. It does not fit the earlier pre-1969 911 control-arm arrangement. Compare the arms on a converted car before ordering.
