Information
Shock absorber upper base, 70 Shore A.
This Shock Absorber Base, Upper Rear is an OE-style rear suspension mounting component designed for Porsche 991 models. It forms part of the upper rear shock absorber assembly and supports proper damper positioning and suspension operation. Installed at the upper section of the rear suspension strut assembly, the base works together with the shock absorber, spring assembly, and top mount components to stabilise suspension movement and absorb chassis loads.
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 5
The upper shock absorber base supports and secures the rear damper assembly to the chassis while helping maintain correct suspension alignment and damping operation. It contributes to stable handling, ride comfort, and controlled suspension movement.
Function
• Supports upper rear shock absorber assembly
• Maintains correct suspension geometry and alignment
• Helps stabilise rear suspension movement
• Absorbs chassis and suspension loads
• Supports proper PASM damper operation
Over time, suspension mounting components are subjected to repeated stress, vibration, and road impact. Wear or deterioration can lead to suspension noise, poor ride quality, inaccurate alignment, or reduced damper performance. Replacing worn upper shock absorber bases restores suspension stability, ride comfort, and proper rear axle control.
When to replace
• Knocking or clunking noises from rear suspension
• Excessive rear suspension movement or instability
• During rear shock absorber replacement
• Visible wear, cracking, or deformation
• Uneven ride quality or vibration
