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.
Fits:
Porsche 911 1974 - 1977

• Quantity: Set of 4 pieces
• Inner Diameter: 16 mm (designed for 16 mm sway bar)
• Function: Supports and isolates the anti-roll bar from the chassis while allowing controlled movement
• Position: Front suspension — stabilizer bar mounting locations (two per side)
• Symptoms of wear: Squeaking, knocking, excessive body roll, looseness, or sway bar movement
• Benefits: OE-spec material hardness and fit, quieter ride, reduced vibration, restored bar performance, and long-term durability
• Installation: Fit each bushing over the stabilizer bar, seat securely in the bracket cradle, and fasten using the correct factory clamps or straps
Over time, stabilizer (sway) bar bushings are subjected to continuous twisting, compression, and exposure to road debris, heat, and oils. The rubber material gradually hardens, cracks, or deforms, reducing its ability to cushion the stabilizer bar and maintain tension. When this occurs, the bar can move or rattle inside its mounts, leading to reduced cornering stability and increased noise during driving.
Replace this set when:
• You hear clunking or squeaking noises from the front suspension
• The car feels less stable in corners or exhibits excessive body roll
• The bushings show visible cracks, tearing, or softness Performing front suspension repairs or sway bar service
Installing a new set of 4 bushings restores the proper preload and isolation in the stabilizer system — reducing roll, eliminating noise, and bringing back Porsche’s signature steering precision and balance.

This kit is comprised of the following items:
Anti-Roll Bars (ARB’s) play an important role in a vehicle’s suspension system, helping to reduce body roll by transferring cornering load from one side of a vehicle to the other.
Often mounted to the vehicle’s chassis with rubber bushes, these bushes ensure the bar works as intended. To prevent the anti-roll bar from moving laterally within its mounts when turning, OE manufacturers will either bond the bushes to the bar, add dead-stops to the bar itself, or rely solely on the clamping pressure of the rubber.
But what happens when those bushes wear and need to be replaced? Often anti-roll bars with bonded bushes come as a costly complete assembly, so the alternative is to fit a more cost-effective unbonded polyurethane replacement, like the many we offer.
In most cases, friction from the bush will prevent any side-to-side bar movement. Still, when turning aggressively or cornering at higher speeds, a laterally shifting anti-roll bar decreases the efficiency and effectiveness of the bar, changing the dynamics of your suspension system in unpredictable ways. It also poses the risk of the bar fouling on other areas of the vehicle or suspension system.

Kit Contents
2 x Rear stabilizer bar drop links — 99633306904
2 x Rear stabilizer bar bushes — 99633379227
4 x Stabilizer bar bush clamp bolts — 90037805501

The rear stabilizer bar helps reduce body roll during cornering by linking suspension movement across the rear axle. The drop links connect the stabilizer bar to the suspension, while the bushes and clamps secure the bar to the chassis. Replacing these components together helps restore correct rear anti-roll bar operation and rear axle stability.
Functions
• Replaces rear stabilizer bar drop links
• Replaces rear stabilizer bar mounting bushes
• Includes stabilizer bar clamps and fixing bolts
• Helps secure the rear anti-roll bar correctly
• Supports stable rear suspension and handling response
• Helps reduce rear suspension knocking, looseness, and vibration
• OE Match repair kit for Porsche 996 Turbo rear stabilizer bar service.
Why Replace This Kit?
Rear stabilizer bar components are exposed to road dirt, moisture, suspension load, vibration, heat, and age. Drop link joints can wear or develop play, bushes can crack or compress, clamps can corrode, and bolts can seize or become damaged during removal. Worn components may cause rear suspension knocking, increased body roll, vague handling, uneven response, or failed inspection. Replacing the drop links, bushes, clamps, and bolts together helps restore a secure and balanced rear anti-roll bar assembly.
When to Replace This Kit
• Rear suspension knocking or clunking is present
• Rear drop links are worn, loose, noisy, or damaged
• Stabilizer bar bushes are cracked, split, compressed, or missing
• Clamps or bolts are corroded, seized, or damaged
• Rear anti-roll bar service or suspension refresh is being carried out
• Handling feels vague or body roll has increased
• The vehicle is undergoing Porsche 996 Turbo suspension restoration.
Where it fits on the car
This kit fits on the rear stabilizer bar / rear anti-roll bar assembly on Porsche 996 Turbo models. It services the rear bar link and mounting points across the rear axle.
