Type 4 Head Stud Kit

This top-quality replacement cylinder head stud kit is designed for all air-cooled Type 4 engines in 1700cc, 1800cc and 2000cc sizes. It provides a complete, matched set of studs and fixings required to securely refit cylinder heads during an engine rebuild—restoring correct clamping force and long-term reliability.

Ideal for replacing stretched, corroded, or damaged original studs, this kit is an essential component when refreshing the top end of any Type 4 engine.

What this kit does (and why it matters)

Cylinder head studs are critical structural fasteners. They clamp the cylinder heads to the crankcase and barrels, maintaining:

• Correct combustion sealing

• Stable compression

• Consistent head torque under heat cycles

On older Type 4 engines, original studs often suffer from corrosion, fatigue, or thread damage. Replacing them during a rebuild helps prevent:

• Head gasket leaks

• Uneven torque loading

• Pulled threads or head movement

• Costly repeat strip-downs

How it works

The studs thread into the engine case and provide fixed mounting points for the cylinder heads. Nuts and washers apply even clamping force when torqued in sequence, allowing the heads to expand and contract with temperature changes while maintaining a secure seal.

This complete kit ensures all studs work together as a matched set, which is especially important on air-cooled engines subjected to wide temperature swings.

Kit contents

Supplied as a complete engine set, including:

• Full set of cylinder head studs

• Correct nuts

• Washers for proper load distribution

Everything required to refit both cylinder heads on one engine.

Engine compatibility

Fits air-cooled Type 4 engines in the following applications:

• VW T2 Baywindow: 1972–1979

• VW Type 25 / T3 (air-cooled): 1980–1983

• Porsche 914: 1970–1976

Engine sizes supported:

Helpful fitting notes

• Always inspect crankcase threads before installation.

• Follow the factory torque sequence and tightening stages.

• Best fitted during a head rebuild or full engine overhaul.

Parts you may also need (recommended)

When replacing head studs, it’s sensible to also consider:

• Cylinder head gasket / sealing kits

• Barrel liner seals

• Valve train components (pushrod tube seals, rocker hardware)

• Full engine gasket set for complete rebuilds
