Sold each.
Fits:
Porsche 996 1998 - 2005
Porsche 997.1 2005 - 2008
Porsche 997.2 2009 - 2012

Thread size / spec: M14 × 1.5 × 100 mm
Supersession: Part 90037805109 is superseded by 90037805101
This bolt secures the rear suspension control arm to the wheel carrier or subframe, providing the clamping force needed to maintain accurate suspension alignment and minimize movement under load.
Over years of service, high torque loads, vibration, and exposure to road conditions can weaken or corrode suspension bolts. A compromised bolt may lead to improper alignment, handling instability, or noise under braking and cornering.
When to replaces:
• During control arm replacement, alignment service, or rear suspension rebuilds
• If original bolts show corrosion, stretching, or thread wear
• As part of preventive maintenance when reassembling load-bearing suspension joints
Replacing with Genuine Porsche hardware ensures structural integrity, precise fit, and lasting performance.

Sold each.

Supersession: 90037805109, 90037805101
Since the control-arm mounting bolt bears major structural loads and undergoes vibration and torque stress, it can become worn, stretched, corroded or fatigued over time. This reduces its ability to maintain correct alignment and clamping force - potentially resulting in handling issues or component wear. Replacement is especially important when performing rear suspension service, control arm replacement, or alignment work. Installing the correct bolt restores reliable mounting integrity and ensures the rear axle geometry remains stable under load.

Porsche Rear Track Control Arms | Design911 Suspension Components for Alignment, Grip & Handling Stability
Rear track control arms are vital suspension components that maintain your Porsche’s precise wheel alignment, handling balance, and stability under cornering and braking. These arms connect the chassis to the rear wheel hubs, allowing controlled suspension movement while keeping the wheels correctly positioned relative to the road. High-quality track control arms ensure consistent tyre contact, optimal geometry, and the responsive, agile performance that defines Porsche handling.
At Design911, we stock a wide range of rear track control arms and related hardware — precision-engineered for strength, durability, and perfect fitment. Crafted from reinforced steel or lightweight aluminium alloys, these components provide lasting rigidity and improved performance. Whether for suspension servicing, alignment correction, or performance upgrades, our control arms restore confidence, stability, and cornering precision to your Porsche.
What Do Rear Track Control Arms Do?
Rear track control arms play a key role in ensuring stable suspension geometry and consistent handling.
Core Functions:
• Maintain rear wheel alignment and suspension geometry.
• Control lateral and longitudinal wheel movement.
• Enhance traction, grip, and cornering stability.
• Distribute load and stress evenly across the chassis.
• Reduce vibration and improve overall ride comfort.
Properly functioning track control arms ensure precise steering response, improved grip, and the balanced handling Porsche vehicles are renowned for.
Why Do Rear Track Control Arms Fail or Degrade?
Rear control arms are subject to high loads, constant motion, and environmental exposure, which lead to wear or fatigue over time.
Common Causes of Failure Include:
• Worn or perished rubber or polyurethane bushes.
• Corrosion weakening the arm’s structure.
• Ball joint wear leading to play or noise.
• Impact damage from potholes or curbs.
• Fatigue or cracking under heavy cornering forces.
When rear control arms wear or fail, symptoms can include uneven tyre wear, vibration, poor handling stability, and rear-end noise — all of which affect safety and performance.
Why Replace or Upgrade Your Porsche Rear Track Control Arms?
Replacing worn control arms restores your Porsche’s precise handling, ride comfort, and alignment accuracy. Upgraded arms offer stiffer construction and improved adjustability for performance driving or track use.
Key Benefits:
• Restores correct wheel alignment and suspension geometry.
• Improves traction, cornering balance, and braking stability.
• Eliminates noise, vibration, and harshness.
• Available with rubber or performance bush options.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Panamera, Cayenne, and other models.
• Ideal for maintenance, restorations, or performance upgrades.
Design911’s Porsche rear track control arms combine strength, precision, and reliability — ensuring your Porsche delivers the control and composure it was built for.
Highlights
• Premium Porsche rear track control arms and components.
• Engineered from high-strength steel or lightweight alloys.
• Restores suspension geometry, handling, and alignment.
• Available in fixed or adjustable performance designs.
• Perfect for both classic and modern Porsche models.
• Ideal for servicing, suspension upgrades, or race preparation.
