Product Information
This Porsche Genuine OE Shock Absorber Upper Base is an original factory rear suspension mounting/support component designed for the Porsche 911 (991 generation). Also referred to as a support element, upper base, or upper spring/shock support, this component forms part of the rear shock absorber and coil spring assembly.
Sold individually, 2 required - fits left or right suspension strut
Fits:
Porsche 991.1 Carrera 2012 - 2016
Porsche 991.2 Carrera 2017 - 2019
Porsche 991 Turbo 2014 - 2016 (I352 / I475)*
Porsche 991 Turbo 2017 - 2021 (I352 / I475)*
* I352 - for cars with electronic damper control for PASM and PDCC
* I475 - for cars with PASM electronic damper control
Diagram ref no
The upper base supports the upper section of the rear shock absorber assembly, helping position and stabilise the suspension components within the rear axle setup. It works together with the shock absorber, spring, and mounting hardware to ensure proper damping operation, load distribution, and vibration isolation. On PASM-equipped cars, it also supports the electronically controlled damper system.
Functions & Technical Role
• Suspension support: Provides upper mounting support for the rear shock absorber assembly
• Load distribution: Helps distribute suspension forces into the chassis
• Vibration control: Assists in reducing vibration transfer through the suspension system
• PASM compatibility: Designed for Porsche Active Suspension Management systems
• OEM precision: Manufactured to Porsche factory tolerances for exact fit and handling performance
Fitment / Position on car
• Fitting position: Rear axle
• Location: Upper section of rear shock absorber / spring assembly
• System: Rear suspension / damping system
Suspension mounting components are constantly subjected to:
• Road impacts
• Suspension movement
• Vibration and load transfer
Over time, wear or deterioration can lead to:
• Suspension noise or knocking
• Reduced ride quality
• Excessive movement in the damper assembly
• Poor handling stability
Replacing worn components with genuine Porsche OE parts restores correct suspension operation and preserves factory driving dynamics.
