Replacement reference: 90037827909 → 90037827901

Control arm mounting bolts endure high forces from cornering, braking, and road irregularities. A bolt that’s worn, corroded, or reused may not hold correct torque or clamping force - compromising alignment and suspension performance.

When to Replace:
During front suspension removal, control arm replacement or realignment.
 If the original bolt shows corrosion, thread damage, or distortion.
 As part of preventative maintenance on high-performance or heavily used vehicles.

Using a new bolt restores proper torque specification, secure mounting and ensures your Porsche’s suspension operates reliably and precisely.

About Cross Member & Parts

Porsche Suspension Cross Member & Parts | Design911 Precision Components for Strength, Alignment & Stability

The suspension cross member — also known as a subframe or suspension carrier — is a structural component that supports key elements of your Porsche’s chassis, including the suspension arms, steering rack, and drivetrain mounts. It provides rigidity, alignment, and load distribution, ensuring that suspension geometry remains consistent under braking, cornering, and acceleration. A properly aligned and structurally sound cross member is essential for precise handling, comfort, and safety.

At Design911, we supply a full range of suspension cross members, mounts, and associated components, engineered for accuracy, strength, and corrosion resistance. Manufactured using reinforced steel or high-grade aluminium, these parts are designed to maintain chassis integrity and suspension precision. Ideal for repairs, restorations, or performance upgrades, our cross members and hardware deliver long-lasting strength and the stability your Porsche deserves.

What Do Suspension Cross Members Do?

The cross member serves as the main support structure for the suspension system, keeping all critical components properly aligned and securely mounted.

Core Functions:
• Support the lower suspension arms, steering rack, and drivetrain.
• Maintain correct suspension geometry for accurate alignment.
• Distribute loads evenly across the chassis.
• Increase torsional rigidity for better handling stability.
• Reduce vibration and noise by isolating components.

A strong, undamaged cross member ensures that your Porsche’s suspension and steering systems work together seamlessly for maximum performance and comfort.

Why Do Suspension Cross Members and Parts Fail or Degrade?

Despite their strength, cross members are subject to stress, corrosion, and fatigue over years of driving, especially in high-performance or harsh environments.

Common Causes of Failure Include:
• Corrosion from road salt, water, or debris.
• Impact damage from potholes, kerbs, or collisions.
• Metal fatigue or cracking under extreme stress.
• Worn or damaged mounting bushes or bolts.
• Misalignment caused by chassis distortion or improper repairs.

When these issues arise, drivers may notice poor handling, uneven tyre wear, clunking noises, or instability — all signs that inspection or replacement is required to maintain safety and control.

Why Replace or Upgrade Your Porsche Suspension Cross Member?

Replacing a damaged or corroded cross member restores chassis alignment, strength, and suspension performance. Upgraded or precision-engineered replacements ensure long-term reliability, improved rigidity, and enhanced handling characteristics.

Key Benefits:
• Restores correct suspension geometry and alignment.
• Improves handling, safety, and steering response.
• Reduces vibration and structural flex.
• Constructed from corrosion-resistant steel or aluminium.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Cayenne, Macan, and Panamera models.
• Ideal for restorations, structural repairs, or performance upgrades.

Design911’s Porsche suspension cross members and parts combine precision engineering and durability, ensuring your Porsche remains strong, balanced, and responsive on every drive.

Highlights

• Premium Porsche suspension cross members, mounts, and bolts.
• High-strength steel and alloy construction.
• Precision-engineered for alignment and rigidity.
• Enhances suspension geometry and vehicle balance.
• Suitable for both classic and modern Porsche models.
• Perfect for restoration, servicing, or performance tuning.
