Shock absorber bump stop. Rear axle.
The Porsche Genuine OE Rear Shock Absorber Bump Stop (Part No. 99133310502) is an original factory rear suspension buffer / additional spring element designed for Porsche 991 models equipped with PASM (Porsche Active Suspension Management). Mounted on the rear shock absorber assembly, this component acts as a protective cushion at the end of suspension travel, helping absorb heavy impacts and preventing the suspension from bottoming out. Porsche also refers to it as an additional spring or shock rubber stop.
Sold individually, 2 required -  fits left or right suspension strut

Fits:
For cars with PASM
Porsche 991.1 Carrera 2012 - 2016
Porsche 991.2 Carrera 2017 - 2019
Porsche 991 Turbo 2014 -2021

The bump stop compresses during extreme suspension movement, cushioning the suspension when the shock absorber approaches full compression. This helps protect the damper, spring assembly, and chassis from excessive impact forces.

On PASM-equipped vehicles, the bump stop also contributes to maintaining the correct suspension characteristics and ride quality under dynamic driving conditions.

Functions & Technical Role
• Suspension protection: Prevents harsh bottoming-out of the rear suspension
•  Impact absorption: Cushions heavy suspension compression loads
•  Ride quality support: Reduces harsh impacts and vibration transfer
•  PASM compatibility: Designed specifically for electronically controlled PASM suspension systems
•  OEM precision: Engineered to Porsche factory specifications for exact fit and damping characteristics

Performance-oriented Porsche suspensions often use progressive bump stops that function as a secondary spring during heavy suspension compression.

Fitment / Position on car
•  Fitting position: Rear axle
•  Location: Mounted on rear shock absorber / damper assembly
•  Side: Left = Right
•  System: Rear suspension and damping system

The rear bump stop protects the suspension and shock absorber from damage during heavy compression. It also helps maintain ride comfort, handling stability, and proper PASM suspension performance.

When to replace
•  Suspension bottoming-out or harsh rear impacts
•  Cracked, collapsed, or deteriorated foam/rubber
•  Knocking noises from the rear suspension
•  During shock absorber replacement or suspension overhaul
•  Reduced ride quality or suspension control

Shock absorber bump stop. Rear axle.
This Rear Shock Absorber Bump Stop is an OE-style rear suspension damping component designed for Porsche 991 models equipped with PASM (Porsche Active Suspension Management). It cushions suspension movement at full compression and protects the rear shock absorber assembly from excessive impact loads.
Sold individually, 2 required -  fits left or right suspension strut

Fits:
For cars with PASM
Porsche 991.1 Carrera 2012 - 2016
Porsche 991.2 Carrera 2017 - 2019
Porsche 991 Turbo 2014 -2021

This OE match rear shock absorber bump stop is a direct replacement for the original Porsche suspension component fitted to Porsche 991 Carrera, Carrera S, Turbo, Turbo S, and related PASM-equipped variants. Manufactured to OE specifications, it is designed to provide progressive suspension cushioning while preserving factory ride quality and handling characteristics.

Installed on the rear shock absorber shaft beneath the dust cover, the bump stop acts as a secondary suspension cushion during heavy suspension compression. When the suspension reaches near full travel under hard cornering, braking, uneven road surfaces, or pothole impacts, the bump stop absorbs excess force before the suspension reaches its mechanical limit. This helps prevent metal-to-metal contact and protects the shock absorber, mounts, and chassis from damage.

Function
•  Cushions rear suspension at full compression
•  Protects rear shock absorbers from impact damage
•  Prevents metal-to-metal suspension contact
•  Helps maintain stable ride comfort and handling
•  Reduces stress on suspension mounts and chassis

Over time, bump stops can deteriorate due to repeated compression, ageing, heat exposure, and moisture. A damaged or collapsed bump stop may reduce suspension protection, increase harsh impacts, and accelerate wear on shock absorbers and mounting components. Replacing worn bump stops restores suspension cushioning, ride comfort, and proper damper protection.

When to replace
•  Cracked, compressed, or deteriorated bump stop material
•  Harsh rear suspension impacts or bottoming-out
•  During rear shock absorber replacement
•  Increased suspension noise or vibration
•  Preventative maintenance on higher-mileage vehicles
