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

Diagram ref no 8

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

Diagram ref no 8

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

Check fitment for your specific vehicle (model, year, engine) before ordering.

Required Quantity
Two washers are specified across the rear shock absorber and coil spring assemblies for the applicable chassis configurations.

What Is This Part?
This is the lower concave washer used within the rear shock absorber and coil spring assembly. Its dished shape provides a seating surface for the adjoining components, so its profile and fitted orientation matter when the assembly is rebuilt. It works alongside the damper, spring and associated seating hardware rather than providing damping itself. OE Match is a Porsche-focused replacement-parts brand; this washer should be selected against the vehicle's chassis equipment as well as its model and year.

What Does This Part Do?

• Provides a shaped seat: Forms the lower spring-disc interface within the applicable rear suspension assembly.
• Supports correct assembly: Works with the adjoining spring and damper hardware in their intended arrangement.
• Maintains the seating profile: Provides the concave contact surface required at this position.

Why Replace This Part?
Replacement may be appropriate if inspection finds corrosion, cracking, distortion or damage to the seating surface. A washer that has lost its intended shape may no longer sit correctly against the adjoining components, so it should be assessed when the rear spring and damper assembly is dismantled.

Renewing a damper does not automatically mean this washer must be replaced. Check its condition alongside the spring seats, mounts and other hardware, and replace any component that is damaged or unsuitable for reuse. Rear suspension noise should be traced to its cause rather than assumed to come from this washer.

When to Replace This Part?

• Visible deterioration: Significant corrosion, cracking or loss of material around the seating surface.
• Distorted profile: Bending, flattening or other damage that prevents correct seating.
• Damaged contact areas: Pronounced wear or fretting where the washer meets adjacent components.
• Incorrect or missing hardware: Inspection confirms that the lower washer is absent or the wrong version has been fitted.
• During suspension dismantling: Inspect the washer when access is available and replace it if its condition makes reuse unsuitable.

Where Is This Part Fitted?
Location: Within the rear shock absorber and coil spring assembly, at the lower concave washer or spring-disc position. Retain the correct component order and orientation when rebuilding the assembly.

Required Quantity

Two mounts are required across the rear shock absorber assembly for the matched Porsche 991 and 992.1 applications.

What Is This Part?

This is the upper mounting component in the rear shock absorber assembly, also described as a shock absorber bearing. It works with the damper and associated fixing components to support the damper at its upper attachment. The surrounding assembly includes separate spring supports, inserts, protective bellows and other hardware, whose condition should also be checked during dismantling. OE Match is a Porsche-focused replacement-parts brand whose component selection considers original references, application, fit and function.

What Does This Part Do?

• Supports the rear damper: Forms part of the upper attachment that holds the shock absorber in its fitted position.
• Locates the mounting connection: Works with the associated inserts and fixings to maintain the intended seating of the upper damper assembly.
• Limits unwanted mounting movement: A serviceable mount supports a secure connection, rather than allowing looseness at the attachment point.

Why Replace This Part?

A worn, damaged or poorly seated rear upper mount can contribute to knocking or rattling around the damper attachment. Replacement is appropriate when inspection confirms deterioration, damage to the fixing area or play within the mount itself. Renewing the mount addresses the mounting fault rather than leaving a damaged attachment in place when other suspension work is completed.

Inspect the mount when replacing a rear damper, but do not assume that every suspension noise requires a new mount. Worn bushes, drop links and loose hardware can produce similar symptoms. Establish the source of the noise and check the associated fixing components before deciding which parts need replacement.

When to Replace This Part?

• Confirmed mounting noise: Knocking or rattling over bumps has been traced to the rear upper damper mount.
• Visible damage: The mount is cracked, distorted or otherwise damaged.
• Excessive play: Inspection identifies movement within the mount rather than elsewhere in the suspension.
• Poor seating: The mount or its fixing area no longer seats correctly with the associated components.
• During damper removal: Dismantling reveals deterioration that makes the existing mount unsuitable for reuse.

Where Is This Part Fitted?

Location: At the upper attachment of the rear shock absorber assembly, where the damper connects to the vehicle's mounting structure. It works with the upper fixing hardware and adjoining mounting components.

FAQs

• Should I replace the mounts with new rear shock absorbers?
  Inspect them while the dampers are removed. Replace mounts that are worn, damaged, noisy or unsuitable for reuse rather than automatically retaining them.
• Does rear suspension knocking prove the mount has failed?
  No. Mounts, bushes, drop links and fixing hardware can produce similar noises. Inspection should identify the source before parts are replaced.
• What else should be checked during this repair?
  Check the adjoining inserts, fasteners, bump stops and protective bellows, and replace any items found to be damaged or deteriorated.
