What the Rear Anti-Roll Bar Hardware Kit Does
The anti-roll bar system works to stabilise the rear of the Porsche 914 by reducing body roll during cornering. This kit ensures the correct mounting and reinforcement of the bar, allowing it to function effectively.
Key Functions
- Provides secure mounting points for the sway bar
- Reinforces the rear suspension console area
- Maintains proper bar geometry and alignment
- Reduces rear-end body roll under lateral load
- Improves cornering balance, stability and driver confidence
- Ensures correct bushing and bracket fitment for long-term reliability
A properly mounted rear anti-roll bar transforms the handling of a Porsche 914—especially when combined with refreshed suspension components.
The Porsche 914’s rear suspension is known for stress on mounting hardware, especially on cars used for performance driving, autocross or spirited road use. Decades of use take a toll on original parts.
Common Failure Causes
- Aged
bushings that crack, harden or collapse
- Corrosion
on brackets, bolts and washers
- Metal
fatigue from continuous lateral forces
- Previous
incorrect installations leading to weakened mounting points
- Reinforcement
plates separating due to age or rust
- Chassis flex stressing original mounting areas
Once hardware wears or fails, the sway bar becomes ineffective—or worse, may detach entirely.
Why This Kit Should Be Replaced or Installed
Installing a fresh anti-roll bar hardware kit restores the Porsche 914’s rear-end stability and prevents further suspension damage.
Benefits of Installing This New Kit
- Ensures correct mounting and geometry of the sway bar
- Improves handling, cornering and overall stability
- Eliminates creaking, clunking or loose-suspension symptoms
- Reinforces structural areas prone to fatigue
- Provides a fresh set of all required brackets, bolts and bushings
- Ideal for restoration or upgrading non-equipped cars

The rear stabilizer bar helps reduce body roll during cornering by linking suspension movement across the rear axle.

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.
