Flat Top Piston Set, 24mm Pin.
Restore engine performance or build a high-capacity air-cooled engine with this OE Match Flat Top Piston Set with 24mm Gudgeon Pin. Produced to OE-style specifications, this precision-engineered piston set is designed for compatible classic Porsche applications using the same engine platform where applicable. Manufactured from premium high-strength aluminium alloy, these flat top pistons provide exceptional durability, precise dimensional accuracy, and excellent heat dissipation for dependable long-term performance. The 24mm gudgeon pin configuration delivers secure piston-to-connecting rod installation, making this set ideal for performance engine builds, complete engine rebuilds, and restoration projects.

Fits:

Stroke: 71 to 78mm
Pistons: Hypereutectic aluminium alloy
Compression Height: 35.50mm
Pin: 24mm

Set includes: 4 pistons, 4 pins and a set of rings.

The piston set converts combustion pressure into rotational force by transferring energy through the connecting rods to the crankshaft. The flat top piston design promotes efficient combustion while maintaining the intended compression characteristics for compatible engine configurations. Precision-machined 24mm gudgeon pin bores ensure accurate alignment and smooth piston movement under demanding operating conditions. Over time, pistons can become worn or damaged through excessive heat, detonation, lubrication failure, or prolonged engine use, resulting in reduced compression, excessive oil consumption, piston slap, and poor engine performance. Replacing worn pistons restores engine efficiency, smooth operation, and long-term reliability.  

What This Product Does:

• Converts combustion pressure into crankshaft rotation.
• Features a precision 24mm gudgeon pin design.
• Restores engine compression and combustion efficiency.
• Supports smooth piston movement within the cylinders.
• Provides reliable sealing when used with new piston rings.
• Improves engine performance and reduces oil consumption.
• Replaces worn, damaged, or heat-affected pistons.
• Provides an OE-style fit for straightforward engine rebuilding.

Symptoms Of Wear Or Failure:

• Low engine compression.
• Excessive oil consumption.
• Blue exhaust smoke caused by oil burning.
• Piston slap or knocking noises.
• Loss of engine power or acceleration.
• Damaged piston crowns or cracked ring lands.
• Excessive cylinder blow-by.
• Damage identified during engine overhaul.

Why Replacement Matters:

• The pistons are among the most highly stressed components within the engine, converting combustion energy into mechanical power while maintaining compression and efficient combustion. Worn or damaged pistons can reduce engine performance, increase oil consumption, create excessive blow-by, and accelerate wear throughout the engine. Correct piston and gudgeon pin fitment is essential for smooth operation, durability, and reliable power delivery.
• Replacing worn pistons with this OE Match Flat Top Piston Set restores engine compression, improves combustion efficiency, reduces oil consumption, and supports dependable engine performance. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Flat Top Piston Set with 24mm Gudgeon Pin provides reliable fit, performance, and durability for classic Porsche engine maintenance, performance upgrades, repairs, and restoration projects.
