Rohler for Porsche
Rohler parts for Porsche models from Design911
A Quick Look at Rohler
Rohler 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 Rohler 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 to choose these parts include resolving wear-related problems, restoring consistent operation, and using known, correctly fitting components during routine Porsche maintenance.
- Common symptoms that lead to replacement can include noise, leaks, play in moving parts, or intermittent electrical or hydraulic faults depending on the component type.
- Always match your Porsche model/year and, where possible, cross-check OEM part numbers to confirm you have the correct application.
- When fitting new components, replace critical consumables such as seals, clips, and bolts so the repair lasts and doesn’t have to be revisited.
- Address underlying issues like worn mounts, misalignment, or contamination so the new part is not blamed for an unresolved root cause.
Browse by Category
If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.
Engine Rebuild Parts — Engine rebuild parts are typically used during planned overhauls or when symptoms point to internal wear, such as loss of compression, excessive oil consumption, persistent leaks, abnormal noises, or contamination found during inspection. On Porsche engines, these parts are often renewed together while the engine is apart to reduce the chance of repeat strip-downs and to improve long-term reliability after the rebuild.
- Before committing to an engine rebuild, carry out compression and leak-down tests, inspect bores with a scope, and check the oil/filter for metallic debris.
- Plan to replace “while you’re in there” items like chains, guides, seals, bearings, gaskets, and critical hardware to make the most of the labour involved.
Camshaft covers / Gaskets — Camshaft covers and gaskets are usually replaced to cure oil leaks and tidy up the engine, especially on older or heavily heat-cycled Porsche engines. Hardened or shrunken gaskets, warped covers, and damaged sealing surfaces can all lead to leaks that cause smells, smoke from oil on hot components, and difficulty tracing other potential leak sources.
- Do not rely on simply tightening bolts to stop leaks; follow the correct torque settings and replace gaskets while checking cover flatness and sealing surfaces.
- Inspect the breather or PCV system and crankcase ventilation, as excess pressure can worsen oil leaks around cam covers and gaskets.
Engine Tuning — Engine tuning components are chosen to improve drivability, throttle response, and performance, or to support hardware changes such as intakes, exhausts, or forced induction on Porsche engines. Tuning is also used to smooth out flat spots, refine cold or hot running, and optimise how the engine behaves after significant repairs or modifications, provided the mechanical condition is sound.
- Before tuning, confirm good engine health with checks on compression, fueling, sensor data, cooling, oil temperatures, and that there are no boost or vacuum leaks.
- Remember that tuning cannot fix mechanical faults; resolve any underlying issues first to avoid masking problems or reducing reliability.
Camshaft Covers — Camshaft covers themselves are replaced when they are cracked, warped, or no longer provide a reliable sealing surface, often together with new gaskets. On Porsche engines this is a common job during top-end work, helping to control oil leaks, reduce smells and smoke, and keep the engine bay clean for easier inspection and maintenance.
- When renewing camshaft covers, check for warping, damage around bolt holes, and brittle seals, and follow the specified torque pattern to avoid distortion.
- It is good practice to inspect the breather/PCV system at the same time, as restricted breathing can contribute to recurring leaks around the top end.
Interior & Accessories — Interior parts and accessories are changed to refresh worn touch points, repair broken trim, or add practical storage and comfort upgrades inside your Porsche. Replacing tired components and upgrading key areas can significantly improve the feel of the cabin without altering the car’s core character.
- Many interior parts are model-year specific, so always check compatibility details and part references to ensure correct fitment.
- Use suitable trim tools and replace missing or damaged clips and fasteners during installation to minimise the risk of new rattles or loose panels.

A slim, period-correct mirror for early cars and customs with a two-hole mount that adapts to 20–71 mm centres. Reuse many legacy hole patterns - or lay out two small, clean holes for a factory-tidy install. Same compact bullet housing with custom convex glass for modern visibility.
Fits:
Porsche 911 / 912 1965 – 1974
*** Custom applications reusing or creating 20–71 mm two-hole spacing
Slim profile. Big view. Easy retrofits.
Designed for early cars and hot-rods, the Longhood/Universal uses a two-hole mount that adapts to 20–71 mm centres. Reuse many legacy hole patterns or drill two small, clean holes for a factory-tidy install. The compact bullet housing and custom convex glass deliver modern visibility with a period-correct silhouette.
Highlights
• Universal two-hole pattern: fits 20–71 mm centres
• Low-profile base with flowing arm — period-correct look
• Billet aluminium mirror + base; stainless hardware
• Optics: Custom convex glass provides near-zero blind spots when properly aimed, for driver and passenger sides
• Finishes: Satin Black, Satin Silver or Chrome
• Options: Left, Right, or Pair
What’s Included
• Mirror assembly (Left, Right, or Pair) with convex glass
• Paint-friendly gasket, universal backing plate, stainless hardware
• Layout template + aiming guide
Install Overview
Measure existing holes; if within 20–71 mm, reuse them. Otherwise, mark and drill two small holes using the included layout guide. Place gasket, position base, add the backing plate inside the door, and tighten hardware evenly for a clean, stable mount.
FAQs
• Will it hide my old holes?
Often yes if they’re within 20–71 mm; otherwise fill + re-drill for best results.
• Does convex look “too small”?
The bullet housing is compact by design; convex glass provides the wide view you’re after but just enough to eliminate blind spots.

By simply rotating the cam wheel 180 degrees during installation, you can select either the +2° or +4° timing position, making this a cost-effective performance upgrade that offers greater flexibility than a standard replacement camshaft wheel.
Even better, the price is lower than many genuine replacement camshaft sprockets while delivering real-world performance gains proven on the rolling road.
Why Adjust Camshaft Timing?
The camshaft and crankshaft work together through the timing belt to control valve opening and closing events. While Porsche factory timing settings provide a good balance for production vehicles, they are often no longer optimal after years of service or engine rebuilding.
Several factors can alter the original camshaft timing:
Cylinder Head Resurfacing
During engine rebuilds, cylinder heads are often skimmed to restore flatness. Many Porsche 944 engines have had this procedure performed multiple times throughout their lives.
Each resurfacing operation slightly alters the relationship between the crankshaft and camshaft, affecting valve timing and engine efficiency.
Hydraulic Tappet Wear
Over time, natural wear and operational changes within the hydraulic tappets can influence valve timing characteristics, reducing engine responsiveness and performance.
Manufacturing Tolerances
Even when new, production tolerances can result in small variations in camshaft timing from engine to engine.
This performance cam wheel compensates for these variables by subtly repositioning the camshaft relative to the crankshaft, advancing intake valve opening events to improve cylinder filling and increase engine output.
Dyno-Proven Performance Gains
Extensive rolling road testing has demonstrated clear performance improvements over the original factory camshaft timing.
+4° Setting
The +4° position provides the greatest torque increase in the lower and mid-range rev band.
Benefits include:
- Up to 10 Nm increase in torque
- Improved acceleration
- Stronger mid-range response
- Enhanced road driving characteristics
- Improved flexibility during everyday driving
Peak gains are achieved up to approximately 5000 RPM.
+2° Setting
The +2° position also produces a significant torque increase but is optimised for higher engine speeds.
Benefits include:
- Improved upper RPM performance
- Increased peak horsepower
- Strong high-rev power delivery
- Enhanced track performance
- Improved top-end engine response
Above approximately 5000 RPM, the +2° setting delivers the strongest horsepower gains.
Which Setting Should You Choose?
+4° Position – Ideal for Road Cars
The +4° setting is recommended for:
- Fast road use
- Daily driving
- Touring
- Improved drivability
- Enhanced low and mid-range torque
This setting delivers a more responsive engine where it is used most often on the road.
+2° Position – Ideal for Track Use
The +2° setting is recommended for:
- Motorsport applications
- Track days Competition use
- High RPM operation
- Maximum peak horsepower
Drivers seeking ultimate top-end performance will benefit most from this configuration.
Simple Installation
Unlike many performance camshaft timing solutions, this cam wheel retains the original timing reference marks on both sides.
This allows:
- Straightforward installation
- Accurate timing belt alignment
- Easy selection of either timing position
- Factory-style installation procedures
The wheel is designed to fit directly in place of the original component.
Corrosion-Resistant Construction
Manufactured from steel and galvanised for corrosion protection, the cam wheel is built for long-term reliability and durability.
The kit also includes a new locating wedge to ensure accurate positioning and installation.
Package Contents
Supplied complete with:
- 1 x Galvanised Steel Performance Cam Wheel

Porsche 928 Flexplate Clamp Upgrade - Permanent Solution to the 928 Flexplate Problem
Protect Your V8 Engine from Catastrophic Failure
The Porsche 928 V8 engine is known for its performance and
engineering excellence, but it also has a well-documented weakness known as the
flexplate problem. If left unaddressed, this issue can lead to severe internal
engine damage and complete engine failure.
Fits:
- Porsche 928 4.5L 1978-82
- Porsche 928S 4.7L 1981-83
- Porsche 928S2 4.7L 1984-86
- Porsche 928S4 5.0L 1987-92
- Porsche 928GT 5.0L 1989-91
- Porsche 928GTS 5.4L 1992-95
Diagram Ref No 25
This upgraded flexplate clamp is engineered as a functional and permanent solution to prevent crankshaft end float movement and protect the axial thrust bearings.
What the Flexplate Problem Is
In the Porsche 928 automatic transmission setup, the flexplate connects the crankshaft to the torque tube driveshaft. If the clamping system fails or loosens, the crankshaft can be forced forward under load.
When this happens:
- The axial crankshaft thrust bearings wear rapidly
- Excessive crankshaft end float develops
- The crankshaft moves forward into the engine block
- The lower block can be permanently damaged
It only takes 3 to 5 mm of forward crank movement for catastrophic damage to occur. Once the crankshaft bores into the block, the engine is effectively written off.
What This Upgraded Flexplate Clamp Does
This redesigned clamp secures the original flexplate clutch sleeve correctly and evenly, preventing forward crankshaft movement.
Unlike other aftermarket solutions, this clamp design focuses purely on mechanical integrity and correct force distribution.
Key design improvements include:
- Three precision-machined circular segments that fit perfectly around the original flexplate sleeve
- Even clamping force across all segments
- Three high-strength M8 12.9 grade socket head bolts
- Torque specification of 60Nm for secure fastening
- Compact, lightweight design to reduce centripetal forces
Why Other Designs Can Fail
Many flexplate clamp designs use two-piece clamping systems around a three-segment shaft. Basic vector force analysis shows that this design cannot distribute compression force evenly across all segments.
Uneven force distribution leads to:
- Inconsistent clamping pressure
- Potential loosening over time
- Continued crankshaft movement risk
Even Porsche’s original clamp used a simpler two-segment design with a single bolt.
This upgraded clamp eliminates uneven load distribution by using a three-part circular design with equalised clamping forces.
Why You Should Upgrade
You should strongly consider installing this flexplate clamp
if:
- You own a Porsche 928 with automatic transmission
- Your engine has never had the flexplate fix performed
- You are rebuilding or restoring a 928 V8
- You want preventative protection against thrust bearing failure
- You are experiencing signs of crankshaft end float
Symptoms of flexplate issues may include:
- Unusual engine noises
- Difficulty maintaining correct crankshaft end play
- Thrust bearing wear during engine rebuild
- Visible crankshaft forward movement
Installing this upgraded clamp holds the driveshaft securely as originally intended and eliminates the flexplate problem completely when correctly fitted.
Engineering Focused on Functionality
This clamp was developed with one goal: to solve the
mechanical weakness permanently.
- Stronger materials than factory design
- Reduced mass to minimise centrifugal stress
- Balanced clamping across all segments
- Designed for durability under high rotational loads
It provides a long-term preventative solution that protects one of the most valuable components of your 928 — the engine block itself.
Key Benefits at a Glance
- Permanent solution to the Porsche 928 flexplate problem
- Prevents crankshaft forward movement
- Protects thrust bearings and engine block
- Even three-point clamping design
- High-strength 12.9 grade bolts
- Lightweight and mechanically balanced
- Designed for long-term engine protection
