Information
Control Arm Lower REAR
This suspension kit includes two rear lower control arms (2 × 98133104303) designed for Porsche 981 / 982 Boxster and Cayman models. Each arm is engineered to the exact specifications of the original Porsche component, providing precise wheel-carrier positioning, correct suspension geometry and balanced handling on both sides of the rear axle.
SET OF 2.

Diagram ref no 25
• Position on Vehicle: Rear axle — lower control arm (support/fork), left + right
• Function: Controls rear wheel-carrier movement, maintains geometry and supports precise alignment
Replacing both arms as a matched pair ensures the rear suspension behaves consistently on both sides, preventing imbalance caused by uneven bushing wear. It provides equal camber and toe adjustment range, making alignment more accurate and stable. The result is improved rear-end stability, better cornering feel and more even tyre wear.
When and why to replace:
• You experience clunks or knocking from the rear when going over bumps or during cornering.
• Uneven wear on rear tyres or inability to keep rear alignment within spec.
• Bushings or joints show play or corrosion.
• The vehicle is high-mileage or has been subjected to high stress, track use, or suspension removal.
• As part of a full rear-suspension refresh or rebuild.

Information
Rear control arm hexagon head bolt, M 14 X 100.
Designed for the rear axle control arm on Porsche 996 and 997, it provides exact factory fit, strength, and corrosion resistance.
Sold each.
Fits:
Porsche 996 1998 - 2005
Porsche 997.1 2005 - 2008
Porsche 997.2 2009 - 2012
Diagram ref no 18
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Supersession: Part 90037805109 is superseded by 90037805101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.

Rear control arm hexagon head bolt, M 14 X 100.
Built to factory specs for the rear axle control arms on 996 and 997 models, they deliver the fit and strength your high-performance suspension deserves.
Sold each.

Thread size / spec: M14 × 1.5 × 100 mm
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.
