What This Product Does:
- Linking the two sides — It helps distribute load between the left and right lower control arms, improving how the rear axle reacts to cornering or uneven surfaces.
- Maintaining relative geometry — By coupling the motion of the trailing arms, it stabilizes toe and camber changes under load, improving predictability.
- Reducing compliance / slack — The bar and its bushings resist unwanted movement in the lower control arms, preventing them from moving independently in undesirable ways.
- Improving handling balance — Helps reduce unwanted rear-end movement, contributing to better rear grip and more consistent behavior over bumps or transitions.
- Clunking, knocking, or banging noises from the rear suspension over bumps or during load shifts
- Rear-end looseness or vagueness — the back of the car may feel less planted or predictable
- Uneven or accelerated tire wear on the rear, due to geometry variations
- Changes in alignment under load, especially during cornering or when the car is unsettled
- Loss of consistent rear grip, especially on transitions or during spirited driving
- Restores rear stability and predictability — with rigid, properly bushing-supported linkage, the rear behaves more reliably
- Eliminates noise & slack — worn linkage causes audible play; a fresh bar or good bushings cure that
- Preserves alignment / geometry under load — prevents misalignment changes mid-corner
- Improves overall handling feel — better feedback, confidence, and consistency
- Prolongs life of connected parts — less undue stress on arms, mounts, and bushings

What This Product Does:
- Holds the rocker arm in place, connecting it to the chassis or subframe while allowing pivoting motion.
- Allows the rocker mechanism to articulate smoothly, transferring load between trailing arms or controlling geometry changes.
- Helps maintain consistent suspension geometry under load — i.e. when the car is accelerating, braking, or cornering.
- Reduces unwanted movement or slack in the linkage, preserving handling precision and stability.
Symptoms Of Worn Or Damaged Bush:
- Clunking or knocking noises from the rear over bumps or during suspension movement
- Rear-end vagueness or instability — the car may feel less planted or “loose”
- Uneven or strange tire wear on the rear tires, due to misalignment or shifting geometry
- Suspicion that the rear changes behavior under load (e.g. under acceleration / braking)
- Reduced handling precision, especially in transitions or fast directional changes
- Restores handling precision — replaces worn, sloppy bushings with tight, controlled support
- Eliminates noise & play — stops knocking or slack in the rocker arm linkage
- Protects suspension geometry — ensures the rocker arm acts as intended, maintaining correct alignment under load
- Prevents further wear — worn bushings transfer stress to surrounding arms, brackets, or linkage elements
- Improves confidence & stability — rear responses become more predictable, especially at higher speeds or in aggressive driving

Porsche Rear Trailing Arms | Design911 Suspension Components for Stability, Alignment & Handling Precision
Rear trailing arms are vital components in your Porsche’s suspension system, connecting the rear axle or hub carrier to the chassis. They control the rear wheel’s forward and backward motion while maintaining correct alignment, geometry, and stability during braking, cornering, and acceleration. Properly functioning trailing arms are key to preserving the balance, grip, and ride comfort Porsche is famous for.
At Design911, we supply a complete range of rear trailing arms, bushes, and associated components engineered for precision fitment, strength, and durability. Crafted from high-quality steel or aluminium alloys, our trailing arms provide the perfect combination of rigidity and lightweight performance. Whether for routine servicing, restoration, or track-focused upgrades, our parts restore suspension integrity and improve both comfort and control.
What Do Rear Trailing Arms Do?
Trailing arms form a structural link between the chassis and the rear wheel assembly, ensuring that the wheel remains correctly positioned and aligned through all driving conditions.
Core Functions:
• Control rear wheel movement under acceleration and braking.
• Maintain correct rear axle geometry and wheel alignment.
• Absorb road shocks to improve comfort and stability.
• Enhance traction, grip, and straight-line performance.
• Support suspension articulation and chassis balance.
High-quality rear trailing arms keep your Porsche’s suspension geometry stable — ensuring predictable, precise handling on both road and track.
Why Do Rear Trailing Arms Fail or Degrade?
Trailing arms operate under constant load and movement, making them vulnerable to wear, corrosion, and metal fatigue over time.
Common Causes of Failure Include:
• Worn or cracked bushings leading to excess play.
• Corrosion or rust weakening the arm structure.
• Impact damage from road debris or kerb strikes.
• Metal fatigue from repeated high-load driving.
• Loose or damaged mounting bolts affecting alignment.
When trailing arms fail, symptoms include clunking noises, unstable handling, uneven tyre wear, and poor rear-wheel alignment — making timely replacement essential for performance and safety.
Why Replace or Upgrade Your Porsche Rear Trailing Arms?
Replacing worn or damaged trailing arms restores suspension geometry, stability, and control. Upgraded performance arms enhance chassis stiffness, adjustability, and precision — ideal for spirited driving or motorsport use.
Key Benefits:
• Restores suspension alignment and stability.
• Improves handling precision and cornering balance.
• Eliminates vibration, noise, and excess rear-wheel play.
• Constructed from corrosion-resistant, high-strength materials.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, and Macan models.
• Ideal for servicing, performance upgrades, or full restorations.
Design911’s Porsche rear trailing arms deliver exceptional engineering, ensuring your Porsche drives with the strength, precision, and control it was designed for.
