Shock Absorber Parts REAR
- Porsche 914 (1970-1976)
Restore secure rear shock absorber mounting and controlled suspension operation with this OE Match Shock Absorber Mounting Bush, Bottom designed for compatible Porsche rear axle applications.
This is installed on the Shock before inserting the top through the Pot for Shock Absorber (Shock Tower).
2 required per car, 1 per side
Fits:
Diagram Ref No 11
The lower shock absorber mounting bush sits at the connection between the rear shock absorber and its mounting point. It provides a resilient interface that allows the shock absorber to operate through normal suspension movement while helping isolate vibration, impact and mechanical noise from the chassis.
Every time the suspension moves, the mounting bush is subjected to compression, twisting and changing loads. Age, mileage, road conditions and deterioration of the rubber can eventually cause the bush to harden, crack, distort or separate from its metal components.
A worn lower shock absorber bush can allow excessive movement at the mounting point, potentially producing knocking noises and reducing the precision with which the damper controls suspension movement.
Replacing a deteriorated bush with this OE Match Rear Lower Shock Absorber Mounting Bush helps restore secure damper mounting, reduce unwanted movement and maintain predictable rear suspension performance.
What This Product Does:
- Secures the lower end of the rear shock absorber.
- Provides a resilient interface between the damper and mounting point.
- Allows controlled movement as the suspension travels.
- Helps absorb vibration and road shock.
- Reduces transmission of suspension noise into the chassis.
- Helps prevent metal-to-metal contact at the mounting point.
- Maintains accurate shock absorber positioning.
- Controls unwanted movement around the lower damper mounting.
- Supports effective shock absorber operation.
- Helps maintain rear suspension stability.
- Replaces a cracked, worn, distorted or separated mounting bush.
- Provides an OE Match replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Knocking from the rear suspension.
- Clunking when travelling over bumps.
- Rattling from the lower shock absorber area.
- Increased suspension noise.
- Excessive movement at the shock absorber mounting point.
- Rear suspension feeling loose or unsettled.
- Reduced suspension refinement.
- Increased vibration transmitted through the chassis.
- Visible cracking in the rubber bush.
- Rubber becoming hard or brittle.
- Bush becoming distorted.
- Rubber separating from the metal sleeve.
- Damaged or displaced mounting bush.
- Excessive play around the lower shock absorber mounting.
- Uneven or unusual shock absorber movement.
Why Replacement Matters:
- The shock absorber needs a secure mounting point to control suspension movement effectively.
- If the lower bush becomes excessively worn, the damper can move relative to its mounting rather than transmitting suspension forces through the intended path.
- Replacing a worn bush helps restore a controlled connection between the shock absorber and rear suspension.

- Porsche 914 (1970-1976)
This is installed on the Shock after inserting the top through the Pot for Shock Absorber (Shock Tower).
Restore secure rear shock absorber mounting and controlled suspension performance with this OE Match Upper Shock Absorber Mounting Bush, designed for compatible Porsche rear axle applications.
Fits:
- Porsche 914 1970-76
The upper shock absorber mounting bush forms the resilient connection between the rear shock absorber and its upper mounting point. It helps locate the damper securely while absorbing vibration, impact and small movements generated as the suspension operates.
During normal driving, the rear shock absorbers continuously compress and extend as the wheels respond to bumps, road imperfections, acceleration, braking and cornering. These forces are transmitted through the mounting bushes, making their condition important for both suspension performance and refinement.
Over time, the rubber can harden, crack, compress, distort or separate from its associated metal components. A deteriorated upper mounting bush can allow unwanted shock absorber movement, resulting in knocking noises, increased vibration and less precise suspension operation.
Replacing a worn bush with this OE Match Upper Rear Shock Absorber Mounting Bush 91433351401/1 helps restore a secure damper connection and supports predictable rear suspension behaviour.
Diagram Ref No 12
What This Product Does:
- Secures the upper section of the rear shock absorber.
- Provides a resilient connection between the damper and chassis.
- Helps locate the shock absorber correctly.
- Allows the designed degree of movement at the mounting point.
- Absorbs vibration and suspension impacts.
- Helps isolate road noise from the vehicle body.
- Reduces the possibility of metal-to-metal contact.
- Controls unwanted movement around the upper damper mounting.
- Supports consistent shock absorber operation.
- Helps maintain rear suspension refinement.
- Helps reduce knocking and rattling caused by worn mounting components.
- Replaces a cracked, compressed, distorted or deteriorated bush.
- Provides an OE Match replacement for compatible Porsche applications.
Symptoms Of Wear Or Failure:
- Knocking from the rear suspension.
- Clunking when travelling over bumps.
- Rattling around the upper shock absorber mounting.
- Increased suspension noise.
- Creaking from the rear suspension.
- Excessive shock absorber movement.
- Increased vibration transmitted into the body.
- Rear suspension feeling less controlled.
- Reduced ride refinement.
- Visible cracking in the rubber.
- Hardened or brittle rubber.
- Bush visibly compressed or distorted.
- Rubber separating from its metal components.
- Excessive play around the upper shock mounting.
- Damaged or displaced mounting bush.
- Shock absorber no longer sitting securely within its mounting.
Why Replacement Matters:
- The shock absorber needs secure mounting points to control suspension movement effectively.
- If the upper mounting bush deteriorates, the damper may move within its mounting before it can properly react to suspension movement.
- Replacing a worn Upper Rear Shock Absorber Bush helps restore the intended connection between the damper and vehicle structure.
