Supersession: Part 90037805109 is superseded by 90037805101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.
