Information
Stabilizer bar bush set, Front, Size: 20mm.
This rubber‐bush is designed to replace the original 20 mm front anti-roll bar bushes used in the front suspension of classic Porsche 911/930 models (front axle). It fits both the inner and outer mounting points of the stabiliser bar and is suitable for left and right sides.
SET OF 4 bushes
Fits:
Porsche 911 1974 - 1986 Front axle
Porsche 911 Turbo (930) 1975 - 1986 Front axle
Diagram ref no 24.
These bushes cushion the 20 mm diameter front anti-roll (sway) bar mountings, reducing metal-on-metal contact, dampening vibration and noise, and maintaining proper bar alignment under dynamic load. With worn or hardened bushes, the bar can move excessively, causing increased body roll, clunks or changes in handling.
