The rear coil spring spacer cushions and isolates the coil spring from the suspension mounting points, helping reduce vibration and suspension noise while ensuring proper spring alignment.

 It also helps maintain the correct ride height and suspension geometry by distributing load evenly through the rear suspension assembly.

Functions & Technical Role
•  Spring insulation: Reduces vibration and noise transfer through the suspension
•  Load distribution: Supports proper seating of the rear coil spring
•  Ride height support: Helps maintain correct suspension geometry
•  Suspension protection: Reduces stress between spring and mounting surfaces
•  OEM precision: Engineered to Porsche specifications for exact fitment and durability

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

The spring spacer helps reduce suspension vibration and prevents metal-to-metal contact between the coil spring and mounting surfaces. It also supports correct ride height and suspension performance.

When to replace
•  Suspension noise or creaking from the rear axle
•  Collapsed, cracked, or worn spring insulator
•  Uneven spring seating or ride height
•  During rear suspension or shock absorber overhaul
•  Excessive vibration transferred into the chassis

This component is commonly replaced during suspension refurbishment, spring replacement, or preventative maintenance to restore proper rear suspension operation and eliminate unwanted suspension noise or uneven ride height.

The rear coil spring spacer supports and positions the rear coil spring within the suspension assembly. It helps maintain correct ride height, reduces vibration and noise, and ensures stable suspension operation under varying driving conditions.

Function
• Positions and supports rear coil spring correctly
• Maintains proper rear ride height and suspension geometry
• Reduces vibration and suspension noise
• Prevents metal-to-metal contact within suspension assembly
• Helps distribute suspension loads evenly

Over time, suspension spacers can compress, crack, or deteriorate due to repeated suspension movement, load stress, and environmental exposure. A worn spacer may cause suspension noise, uneven ride height, poor spring seating, or increased vibration. Replacing worn spring spacers restores proper suspension support, ride comfort, and chassis stability.

When to replace
•  Suspension squeaks or knocking noises
•  Uneven rear ride height
•  Visible cracking or deformation of spacer
•  During coil spring or shock absorber replacement
•  Preventative maintenance during suspension overhaul

Fits
Porsche 991 2012 Onward - Rear Only

These monoball cartridges replace factory rear shock lower mount bushings with hardened-steel spherical bearings.
The factory rubber acts as a spring in series with the shock. This rubber spring-action is completely un-damped and reduces the shock ability to control the tire contact patch. The spherical bearing allows the damper to do its job and control the contact patch.

High tolerance machined housing allow for simple press fit installation.

The kit includes 2 monoball bearings. 1 per side and inserts into the rear upright.
Order one kit per car

Weather Sealed
Monoball housing and spacers are hard anodized to protect from corrosion. Rubber seals keep the precision bearing from road contaminates for extended life of the product.

Rear shock mount kit.
1 kit required per car



Fits:
Porsche 991 12>> w/ coilovers or shocks

These shock mounts use high strength hardened steel spherical bearings and are direct replacements for the factory mounts. The Teflon lined spherical bearings used in our kit are maintenance-free and require no supplemental lubrication. Included seals prevent contamination from water or grime, thus extending bearing life.

Porsche used spherical bearings on the 991 GT3 and Cup Cars. We went one step further and added larger bearings and weather-seals to ensure longevity.

Fully Weather Sealed

We’ve designed in weather seals to keep dirt out and extend product life. This is the only shock mount suitable for street or extended track use. Dirt and water contaminate ordinary products and accelerate wear.

Improved shock / coilover performance

The spherical bearings pivot freely and eliminate the deflection that is inherent with the factory rubber bushings.
This is important for two reasons:

– The factory rubber acts as a spring in series with the shock. This rubber spring-action is completely un-damped and reduces the shocks ability to control the tire contact patch. The spherical bearing allows the damper to do its job and control the contact patch.
– The factory rubber deflects sideways under cornering loads, causing loss of camber just when you need it most. Our spherical bearings eliminate the deflection, maintaining stable and predictable camber.

These will work with stock springs and coilover suspensions.

Diagram ref no 10

The shock absorber bellow (dust boot) surrounds the piston rod and compresses/extends with suspension movement. Its primary function is to shield the damper shaft seal from contamination. When the original boot cracks, tears, or deteriorates due to heat cycling, road salt, and ageing, dirt can enter the damper assembly - potentially causing premature seal wear and fluid leakage.

This OE Match bellow is manufactured to match original Porsche specifications in length, flexibility, and fitment. It is engineered for correct operation with sport suspension dampers, ensuring proper compression travel and interference-free performance.

Ideal for installation during shock absorber replacement, suspension upgrades, or preventative maintenance.

A damaged or missing shock absorber bellow exposes the damper shaft to debris and moisture, increasing the risk of seal failure and oil leakage. On sport suspension vehicles, where damping loads are higher, proper protection is essential. Replacing worn bellows helps preserve damper performance and prevent costly shock absorber replacement.

Replace the bellow if you notice:
•   Cracked, split, or missing dust boot
•   Visible damper shaft contamination
•   Suspension overhaul or shock replacement
•   Evidence of oil leakage from damper seals
•   Preventative maintenance on high-mileage vehicles
