Rear Lower Control Arm Bushing.

The Rear Lower Control Arm Bushing (FRONT) is a high-quality suspension bushing designed to restore correct mounting and controlled movement of the rear lower control arm on compatible Porsche vehicles. This bushing sits between the control arm and the chassis/subframe, acting as a flexible joint that absorbs road vibration while allowing the suspension to articulate smoothly under braking, acceleration, and cornering loads.

Over time, suspension bushings can deteriorate due to age, heat, road contamination, and repeated flexing. A worn rear lower control arm bushing can lead to clunking noises, unstable handling, uneven tyre wear, and difficulty maintaining proper wheel alignment. Replacing the bushing helps return suspension geometry to factory condition, improving comfort, stability, and overall driving confidence.

What This Product Does:

  • Acts as the pivot point between the rear lower control arm and subframe
  • Absorbs vibration and road shock for a smoother ride
  • Maintains correct suspension geometry and alignment
  • Helps control wheel movement under load (acceleration, braking, cornering)
  • Reduces noise, harshness, and vibration transmitted to the cabin

Symptoms Of Worn Or Failed Rear Lower Control Arm Bushing:
Noise & Vibration
  • Clunking, creaking, or knocking over bumps
  • Vibration through the floor or rear of the vehicle

Handling & Stability Issues
  • Wandering or unstable rear end
  • Poor cornering response
  • Braking pull or imbalance

Wear & Alignment Problems

  • Uneven or accelerated tyre wear
  • Difficulty holding a wheel alignment
  • Rear end “floaty” feel at speed

Visual/Physical Signs

  • Cracks, splits, or visible degradation of the rubber material
  • Play or movement at the bushing when pushed/pulled

Why Replacement Matters:
  • Worn bushings allow uncontrolled movement in the suspension, which degrades stability, steering feel, and driver confidence—especially in corners or sudden manoeuvres.
  • Proper bushings help maintain wheel alignment under load, reducing uneven tyre wear and extending tyre life.
  • New bushings absorb shock and vibration more effectively, reducing harshness and noise transmitted to the cabin.
  • Controlling unwanted movement helps prevent premature wear of control arms, ball joints, and other suspension parts.

About Rear Trailing Arm

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.
