Engle Master Cam Kit - W-110 Grind

These super strong and lightweight chromoly valve spring retainers are designed for use on VW Type 1 aircooled 1200cc to 1600cc engines, making them ideal for both performance builds and high-quality engine rebuilds. Manufactured from Chrome-Molybdenum steel, they offer exceptional strength while keeping overall valvetrain weight to a minimum.

Each retainer is precision CNC machined to exacting tolerances and then heat treated to deliver outstanding durability and resistance to fatigue. This ensures consistent valve control at higher engine speeds and significantly reduces the risk of retainer failure compared to standard pressed steel versions. Thanks to their strength and accuracy, these retainers are considered virtually unbreakable under normal performance use.

These chromoly retainers are suitable for use with single or dual valve spring setups, providing excellent versatility whether you are building a mild fast-road engine or a more aggressive performance motor. By reducing valvetrain mass while increasing strength, they help maintain accurate valve timing, reduce wear on valve guides and stems, and improve overall engine reliability.

Sold as a set of 8, this kit supplies enough retainers to fully equip one complete Type 1 engine.

Fitting Notes & Additional Requirements

• Fits VW Type 1 aircooled engines from 1200cc to 1600cc

• Compatible with single and dual valve springs

• Designed for performance and upgraded valvetrain setups

• Always check installed height and spring compatibility during assembly

• Professional engine building practices recommended

This heavy duty valve cotter set from ENGLE is designed for use on all aircooled Volkswagen engines fitted with 8mm stem valves, making it suitable for both standard rebuilds and high-performance applications. Valve cotters (also known as valve keepers or collets) are a critical component of the valvetrain, locking the valve spring retainer securely onto the valve stem and ensuring consistent, reliable valve operation.

Manufactured to ENGLE’s high standards, these cotters are made for strength, accuracy, and long-term durability. Their precision-machined profile ensures a positive, secure fit between the valve stem and retainer, reducing the risk of slippage or failure under high spring pressures and elevated engine speeds. This makes them especially well suited to engines running heavy duty single or dual valve springs, performance camshafts, and higher RPM limits.

Correctly fitting valve cotters is essential for maintaining valve control and preventing catastrophic valvetrain failure. These heavy duty ENGLE cotters provide peace of mind in both road and competition engines by delivering reliable retention and consistent engagement with the valve stem grooves.

Supplied as a 16-piece set, this kit provides enough cotters to fully assemble one complete aircooled VW engine using 8mm stem valves.

Fitting Notes & Compatibility

• Fits all aircooled VW engines with 8mm valve stem valves

• Suitable for Type 1, Type 2, Type 3 and Type 4 aircooled engines (with 8mm stems)

• Compatible with standard and performance valve spring retainers

• Ideal for use with heavy duty or dual valve springs

• Always inspect for correct seating during assembly

This heavy duty single valve spring set from ENGLE is designed to provide reliable valve control on all VW Type 1 aircooled engines, making it an excellent upgrade for both standard rebuilds and mild performance applications. Compared to standard valve springs, these ENGLE single springs offer increased seat and open pressure, helping to prevent valve float and maintain accurate valve timing, especially at higher engine speeds.

Manufactured to ENGLE’s exacting standards, these springs are engineered for consistency, durability, and long service life. They are ideally suited for use with performance camshafts, upgraded valve train components, or engines that regularly see higher RPM than stock. Despite their increased strength, they remain compatible with single spring configurations, making them a straightforward upgrade without the complexity of dual spring setups.

These heavy duty single valve springs work well with standard or chromoly valve retainers and are commonly used in fast-road engines where reliability and improved control are essential. They are also suitable for engines retaining stock-style heads, provided correct installed height and clearances are confirmed during assembly.

Supplied as a set of 8, this kit provides enough springs to fully equip one complete Type 1 aircooled engine.

Fitting Notes & Additional Requirements

• Fits all VW Type 1 aircooled engines

• Single spring design (not dual springs)

• Suitable for standard and mild performance camshafts

• Always check installed height, coil bind, and retainer compatibility

• Upgraded retainers and valve cotters recommended for performance use

• Professional engine assembly recommended

The Engle W110 performance camshaft is a proven and extremely popular upgrade for VW Type 1 aircooled engines based around 1200cc to 1600cc units. Designed for street use, the W110 delivers strong low and mid-range power while still allowing the engine to pull well into higher RPM, making it ideal for fast-road cars that want a noticeable performance increase without sacrificing everyday drivability.

Compared to milder camshafts, the W110 offers increased duration and lift, improving cylinder filling and airflow through the engine. This results in stronger acceleration, improved throttle response, and a wider usable power band. It works especially well in engines fitted with twin carburettors, a free-flow exhaust, and a sensible compression ratio, making it a favourite choice for spirited road-driven Beetles and other Type 1-powered vehicles.

Manufactured to Engle’s exacting standards, the W110 camshaft features precision-ground lobes and consistent timing profiles for reliable performance and long service life. When correctly matched with supporting components, it offers an excellent balance between street manners and performance potential.

These Engle 28mm cam lifters are a must-have upgrade for high-performance VW Type 1 aircooled engines, especially those running high-lift and aggressive camshafts. Designed to cope with increased valve train loads and higher engine speeds, these lifters provide strength, stability, and reliability where standard lifters can struggle.

Each lifter features a 28mm diameter head and weighs approximately 100 grams, offering an excellent balance between strength and controlled valvetrain mass. The larger lifter face spreads the load more evenly across the cam lobe, reducing wear and helping the camshaft survive in demanding performance and race applications. This makes them particularly well suited to high lift Engle camshafts and other aftermarket performance cams.

Manufactured to Engle’s exacting standards, these lifters are precision finished to ensure correct rotation in the lifter bore, smooth cam break-in, and long service life. When combined with the correct camshaft, valve springs, and break-in procedure, they help maintain accurate valve timing and reduce the risk of premature cam or lifter failure.

Supplied as a set of 8, this kit provides enough lifters to fully equip one complete Type 1 aircooled engine.
