Information
Front Stabilizer Bar Mounting Bushing / Sway Bar Bushing
Size: 16mm
This Stabilizer bar bushing is designed to replace the original 16 mm anti-roll bar mount bush used in Porsche 911 models (1974–1977) models. It secures the stabilizer bar to the chassis, allowing proper flex while isolating vibration and lateral movement.
Sold each, 4 required.
Fits:
Porsche 911 1974 - 1977
Diagram ref no 23
• Inner Diameter: 16 mm (fits 16 mm sway bar)
• Function: Supports and isolates anti-roll bar from chassis while allowing movement
• Position: Front suspension — stabilizer bar mounting location
• Symptoms of wear: Squeaking, sway bar movement, body roll, looseness or play in suspension
• Benefits: OEM-like material and fit, quieter ride, preserved bar function, durability
• Installation: Fit over the bar, seat in bracket cradle, use correct clamps or straps
Over time, stabilizer (sway) bar bushings endure constant twisting, compression, and exposure to heat, oil, and road contaminants. The rubber material gradually hardens, cracks, or deforms, reducing its ability to isolate movement and maintain bar tension.
When this happens, the stabilizer bar can shift or rattle inside the mount, leading to poor handling balance and unwanted suspension noise.
Replace this bushing when:
• You notice clunking, squeaking, or knocking noises over bumps or during cornering
• The car feels less stable in turns or exhibits excessive body roll
• There are visible cracks, tears, or looseness in the rubber mount
• Performing suspension or sway bar service, or during a front-end restoration
Installing fresh bushings restores the correct preload and isolation in the stabilizer system — reducing body roll, eliminating noise, and bringing back that original Porsche steering precision and confidence.
