A Quick Look at Porsche

Porsche information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Porsche is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons people replace these parts include maintaining originality, keeping factory specification, and choosing the latest genuine revisions for peace of mind.
  • Common real-world issues behind many Porsche repairs are age and mileage: oil leaks, cooling system fatigue, brake and suspension wear, corrosion and electrical faults from moisture or heat cycling.
  • Before ordering, confirm part numbers against VIN or option/PR codes, especially for safety‑critical or complex components.
  • When upgrading, decide whether you want pure originality or performance changes, as some aftermarket options may suit specific goals better than genuine.
  • For bigger jobs, replace related seals, hardware and consumables at the same time to avoid repeat labour and compatibility issues.
  • Where available, follow the manufacturer’s fitting and bedding‑in guidance to get the best performance and longevity.

Diagram Ref No 1

Manufactured to Porsche's exact engineering standards, this rear lower wishbone provides the strength, durability and precision required to deliver the handling characteristics, ride comfort and stability expected from a Porsche vehicle. It is an essential component for maintaining correct suspension operation and ensuring factory-level driving dynamics.  

What This Product Does:

  • Connects the rear wheel carrier to the chassis and suspension assembly.
  • Maintains precise wheel alignment and suspension geometry.
  • Controls rear wheel movement during suspension travel.
  • Helps stabilise the vehicle during acceleration, braking and cornering.
  • Supports predictable handling and ride comfort.
  • Provides mounting points for associated suspension bushes and joints.
  • Contributes to tyre wear control and overall suspension performance.

Symptoms Of Wear Or Failure:
  • Uneven or accelerated rear tyre wear.
  • Difficulty maintaining wheel alignment.
  • Rear-end instability during cornering.
  • Clunking, knocking or rattling noises from the rear suspension.
  • Excessive suspension movement.
  • Reduced handling precision.

Diagram Ref No 2

Manufactured to Porsche's exact standards for fit, strength and durability, the rear drop link is designed to withstand continuous suspension movement, road impacts and varying driving conditions. Genuine Porsche components ensure factory-correct fitment, performance and long-term reliability.  

What This Product Does:

  • Connects the rear anti-roll bar to the rear suspension assembly.
  • Transfers stabilising forces across the suspension system.
  • Helps reduce body roll during cornering.
  • Improves vehicle balance and handling performance.
  • Maintains suspension stability during changes in direction.

Why Replacement Matters:

  • Rear drop links are subjected to constant suspension articulation, vibration, road shock and environmental exposure. Over time, the internal ball joints and protective components can wear, reducing their ability to transfer forces effectively between the anti-roll bar and suspension system.
  • A worn drop link can diminish the effectiveness of the anti-roll bar, resulting in increased body roll, reduced cornering stability and unwanted suspension noise. As wear progresses, vehicle handling and driver confidence may be affected, particularly during spirited driving or emergency manoeuvres.
  • Replacing a worn rear drop link restores proper anti-roll bar operation, improves suspension performance and helps maintain the balanced handling characteristics intended by Porsche. Genuine Porsche replacement parts provide exact fitment, exceptional durability and factory-level performance for long-term reliability.

Manufactured to Porsche's exact engineering standards, this rear wishbone is designed to withstand the substantial forces generated during acceleration, braking, cornering and everyday driving. It plays a vital role in maintaining factory suspension characteristics and ensuring the vehicle delivers the precise handling and driving dynamics expected from Porsche.  

What This Product Does:
  • Connects the rear wheel assembly to the vehicle chassis.
  • Maintains correct suspension geometry and wheel alignment.
  • Controls wheel movement throughout suspension travel.
  • Supports vehicle stability during acceleration, braking and cornering.
  • Helps deliver precise handling and predictable road behaviour.

Crankcase Through Bolt O-Ring 
Sold each - 24 required per engine

The Porsche Crankcase Through Bolt O-Ring is a small but critically important sealing component used in Porsche 911 engines from 1965 to 1989. Fitted around the crankcase through bolts that secure the engine case halves together, this O-ring helps prevent oil leakage from one of the most common sealing points found on classic air-cooled Porsche engines.

Fits:

  • Porsche 911 1965-1968 2.0L / 912 SWB (F)
  • Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
  • Porsche 911 1978-1983 3.0L / SC
  • Porsche 911 1984-1986 3.2L
  • Porsche 911 1987-1989 3.2L G50
  • Porsche 911 1975-1977 3.0L Turbo (930)
  • Porsche 911 1978-1989 3.3L Turbo (930)

Diagram ref no 22

Although inexpensive, these O-rings play a vital role in maintaining the integrity of the engine lubrication system. When properly installed, they create a reliable seal around the through bolts, preventing pressurised engine oil from escaping the crankcase and helping to keep the engine clean and leak-free.

Whether you're performing a complete engine rebuild, repairing oil leaks, or restoring a classic Porsche 911, replacing the crankcase through bolt O-rings is considered essential preventative maintenance.

What Does the Crankcase Through Bolt O-Ring Do?

The through bolt O-ring seals the openings where the crankcase through bolts pass through the engine case.

Its primary functions include:

  • Preventing oil leaks from the crankcase
  • Maintaining crankcase sealing integrity
  • Supporting proper oil system operation
  • Helping preserve engine cleanliness
  • Reducing oil loss and contamination
  • Protecting engine components from oil seepage

Because Porsche air-cooled engines operate with a high-capacity dry-sump lubrication system, maintaining effective sealing throughout the crankcase is crucial for long-term reliability.

Why Does the Through Bolt O-Ring Fail?

Over time, the O-ring is exposed to extreme engine heat, oil, pressure fluctuations, and age-related deterioration.

Common causes of failure include:

  • Rubber hardening due to heat cycles
  • Age-related shrinkage
  • Loss of elasticity
  • Oil exposure over decades of use
  • Improper installation
  • Damage during assembly
  • Long-term storage and inactivity

As the O-rings age, they gradually lose their sealing ability and become one of the most common sources of oil leaks on classic Porsche 911 engines.

Common Symptoms of a Failing Through Bolt O-Ring

Signs that the O-rings may require replacement include:

  • Oil leaks around the crankcase
  • Oil residue underneath the engine
  • Persistent oil drips despite replacing other seals
  • Oil staining around through bolt locations
  • Excessive oil mist accumulation on the engine case
  • Leaks becoming worse as the engine reaches operating temperature

These leaks are often mistaken for rocker cover, timing chain housing, or crankshaft seal leaks due to the way oil travels across the engine casing.

When Should You Replace It?

Replacement is strongly recommended whenever the engine is disassembled.

The through bolt O-rings should always be replaced:

  • During complete engine rebuilds
  • During crankcase splitting procedures
  • When repairing major oil leaks
  • During full engine restorations
  • On high-mileage engines undergoing overhaul
  • Whenever the crankcase through bolts are removed
  • As preventative maintenance during engine refurbishment

Because access requires significant engine disassembly, replacing these O-rings during rebuild work is considered standard Porsche engine-building practice.

Manufactured to OE specifications for fit, function and durability, this replacement window regulator provides dependable performance and correct alignment of the window glass. It is an ideal solution for replacing worn, damaged or failed original regulators and restoring proper window operation. 

What This Product Does: 
  • Controls the raising and lowering of the front right window glass.
  • Transfers movement from the window motor to the window mechanism.
  • Maintains smooth and controlled window operation.
  • Supports correct alignment of the window glass within the door frame.
  • Helps ensure proper sealing against weather, wind and noise.
  • Restores reliable functionality of the vehicle's power window system.

Symptoms Of Wear Or Failure:
  • Window moves slowly, unevenly or becomes stuck.
  • Grinding, clicking or popping noises from inside the door.
  • Window drops into the door unexpectedly.
  • Window tilts or becomes misaligned during operation.
  • Window stops moving despite the motor operating.
  • Intermittent window operation.
  • Excessive play in the window mechanism.
  • Difficulty fully opening or closing the window.

Why Replacement Matters:

  • Window regulators are subjected to constant use, vibration, temperature fluctuations and mechanical stress. Over time, cables, pulleys, guide rails and moving components can wear, stretch or break, leading to poor window operation or complete failure.
  • A damaged window regulator can leave the vehicle vulnerable to water ingress, increased wind noise, security concerns and inconvenience. In some cases, a failed regulator may cause the window glass to become unsupported, potentially resulting in damage to the glass or door components.

Why Replace This Part?
Door mirror glass can become cracked, scratched, cloudy or damaged from impact, road debris, weather exposure or cleaning wear. Dimmable mirror glass can also fail internally, causing dark patches, stains, liquid marks or reduced visibility. If the mirror glass includes lane change assist functionality, damage or incorrect replacement glass may also affect the visibility of the side assist warning indicator. Replacing the glass with a Genuine Porsche OE aspherical dimmable mirror glass helps restore the correct field of view, factory appearance and original mirror functions, including lane change assist compatibility where fitted.

When to Replace This Part
•   If the left mirror glass is cracked or broken
•   If the glass is scratched, cloudy or discoloured
•   If the auto-dimming function has failed
•   If the mirror has dark patches, staining or liquid marks
•   If the lane change assist indicator area is damaged or no longer visible
•   If mirror heating is no longer functioning due to glass failure
•   If visibility through the mirror is poor
•   After impact damage to the exterior mirror
•   During mirror housing repair or replacement
•   When restoring the car with correct Porsche OE parts.

Where It Fits on the Car
This mirror glass fits in the left-hand exterior door mirror assembly. For left-hand-drive vehicles, this is normally the driver-side mirror. It installs into the mirror carrier inside the door mirror housing and connects to the relevant heating, dimming and lane change assist connections where fitted.
