OE Match racing-specification silent block set for the rear axle subframe on Porsche 996 and 997 models. Each set contains three bushes to service one side.
Fits
- Porsche 997
- Porsche 996
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
These bushes form part of the rear subframe mounting arrangement. They are replacement mounting components, rather than a complete subframe or its structural side sections.
Functions
- Provides replacement bushes for the rear subframe mounting locations.
- Allows renewal of the mounting bushes on either side using the same set specification.
Technical Details
- Specification: racing version.
- Position: rear axle subframe.
- Contents: three bushes per set, covering one side.
- Application: suitable for either Left or Right.
(Set of 3 bushings for one side) for Left and Right, 2 Sets required
Symptoms of Fault
Knocking at the rear, mounting play, inconsistent alignment or irregular tyre wear can warrant inspection of the subframe bushes and surrounding components. These symptoms do not establish that the bushes alone are at fault.
Why Replacement Matters
Renewal addresses worn mounting components during rear suspension repairs or a planned racing-specification build. Inspect the subframe, fixing points and associated hardware before fitting; replacement bushes do not repair corrosion or structural damage.
FAQs
Does one set cover both sides?
No. One set supplies three bushes for a single side; two sets are required to service both.
Is this the standard specification?
No. This is the racing version. Match the specification to the intended suspension setup rather than assuming standard mounting characteristics.
Should alignment be checked afterwards?
Include a geometry check when planning subframe or suspension work.

OE Match rear axle subframe silent block set for Porsche 996 and 997 models. Bush hardness is increased by 37% compared with the standard street version, with three bushes supplied for one side.
37% Harder than standard street version.
Fits
Porsche 997
Porsche 996
Check fitment for your specific vehicle (model, year, engine) before ordering.
What This Product Does
These bushes form part of the rear subframe mounting arrangement, providing a compliant connection within the assembly. This set replaces the bushes rather than the complete subframe or its side sections.
Functions
- Provides compliance at the rear subframe mounting points.
- Accommodates movement within the mounting assembly.
- Offers a harder bush specification than the standard street version.
Technical Details
- Application: rear axle subframe.
- Contents: three bushes for one side.
- Hardness: 37% above the standard street specification.
- (Set of 3 bushings for one side) for Left and Right, 2 Sets required
Symptoms of Fault
Rear-end knocking, movement at the mounting points, vibration or difficulty maintaining wheel alignment can warrant inspection. Uneven tyre wear may also indicate suspension wear or incorrect geometry. These symptoms are not specific to the bushes, so check the surrounding assembly before deciding which components need replacement.
Why Replacement Matters
Deteriorated mounting bushes can allow unwanted movement within the rear assembly. Replacement addresses bush wear, while selecting this harder specification should form part of a considered suspension setup. Inspect the subframe, mounting points and associated hardware during the work; new bushes do not repair corrosion or structural damage.
FAQs
- Does one set cover both sides?
No. Each set contains three bushes for one side; two sets are required for left and right. - Is this the standard-hardness version?
No. Its specified hardness is 37% above the standard street version. - Should alignment be checked afterwards?
Yes. Arrange a wheel alignment check following rear subframe work.

OEMatch Rear Sub Frame — Control, Stability, Comfort
The rear sub frame is the structural support for a Porsche’s rear suspension and drivetrain, locating suspension arms, differential mounts and fixing points so geometry is preserved under load. OEMatch offers replacement and upgrade options prepared for Porsche models to restore alignment, reduce vibration and recover handling balance.
Available Types- Replacement rear sub frames sized for direct chassis fitment
- Reinforcement and performance sub frames to reduce flex
- Mounting kits including bushes, brackets and fasteners
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original rear sub frame.
OE (Original Equipment) refers to parts matching original specifications for the rear sub frame and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM rear sub frame engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The rear sub frame supports suspension arms, differential and drivetrain mounts, and helps maintain correct suspension geometry during cornering, braking and acceleration. It also helps control vibration and transmits loads into the vehicle body. OEMatch provides a wide selection of Porsche-suitable rear sub frames, replacement parts and mounting hardware and catalogues over 4,000 part numbers with more than 8,700 OE cross‑references to aid correct application choice.
Benefits Include- Restores correct suspension geometry and alignment
- Improves chassis rigidity for steadier handling
- Reduces vibration and irregular tyre wear
- Corrosion and rust that weaken metal structure
- Cracks or distortion following impact or overload
- Worn bushes or degraded mounts allowing excess movement
Replacing a degraded rear sub frame restores alignment and structural support so suspension components retain their intended geometry. That recovery of rigidity and locating accuracy helps return predictable handling, prevents premature tyre wear and reduces noise and vibration transmitted into the cabin. Choosing correctly sized replacement parts and genuine mounting hardware aids a straightforward refit for Porsche models.
Advantages- Options for corrosion-resistant finishes and reinforced designs
- Parts selected for compatibility with Porsche suspension layouts
- Availability of accompanying mounting hardware and bushes
