Information
Front shock absorber bump stop.
The Genuine OE Porsche front shock absorber bump stop, part number 99134330103, is an original Porsche suspension component designed to protect the front shock absorber assembly from excessive compression under heavy suspension load. Installed on the front suspension strut, this high-quality polyurethane/rubber stop acts as a secondary cushioning element, helping to prevent metal-to-metal contact during aggressive driving, hard braking, uneven road surfaces, or full suspension travel.
Sold individually, 2 required - fits left or right suspension strut
Fits:
Porsche 981 Boxster 2012 - 2016 cars with PASM
Porsche 981C Cayman 2014 - 2016 cars with PASM
Porsche 982 Boxster 2017>> cars with PASM
Porsche 982C Cayman 2017>> cars with PASM
Porsche 991.1 Carrera / Turbo 2012 - 2016 cars with PASM (excluding standard and sport type chassis)
Porsche 991.2 Carrera / Turbo 2017 - 2019 cars with PASM (excluding standard and sport type chassis)
Diagram ref no 6
This component is essential for maintaining ride quality, suspension stability, and correct shock absorber operation. Over time, bump stops can deteriorate due to heat cycles, age, moisture, and repeated suspension compression, leading to cracking, collapse, or reduced cushioning performance. Replacing worn bump stops helps restore proper suspension protection and ensures the shock absorber can operate correctly throughout its full range of movement.
Functions & Technical Role
• Protects the front shock absorber during full suspension compression
• Prevents harsh bottoming-out impacts
• Helps maintain correct suspension geometry under load
• Reduces shock absorber and strut damage caused by excessive travel
• Assists with vibration damping and ride refinement
• Supports optimal PASM suspension performance
• OE-quality material construction for long-term durability
Fitment / Position on car
• Front suspension
• Fits left or right side
• Mounted on the front shock absorber/strut assembly
The front bump stop is a critical protective component within the Porsche suspension system. During heavy cornering, sudden impacts, aggressive driving, or rough road conditions, the suspension can compress rapidly. Without a properly functioning bump stop, excessive suspension travel can damage the shock absorber, strut mount, spring assembly, and other suspension components.
A deteriorated or collapsed bump stop may also lead to harsh suspension noises, reduced ride comfort, poor damping control, and premature shock absorber wear. Replacing worn bump stops with Genuine Porsche components helps maintain factory suspension performance, protects expensive suspension hardware, and preserves the precise handling characteristics Porsche vehicles are known for.
When to replace. Replace the front shock absorber bump stop if you notice:
• Cracked, split, or crumbling rubber material
• Suspension knocking or bottoming-out noises
• Excessive harshness over bumps
• Oil leaks or damage around the shock absorber
• Suspension overhaul or shock absorber replacement
• Visible compression damage or deterioration
• Reduced suspension damping performance
• High mileage or ageing suspension components
