Valve Adjuster Set, Scat Swivel Foot, Set Of 8

Scat Swivel Foot Valve Adjuster Set (Set of 8) - Part #20118

Optimize Your Valve Train Geometry

The Scat Swivel Foot Valve Adjuster set is a critical upgrade for Volkswagen enthusiasts looking to improve engine longevity and performance. Unlike standard rigid adjusters that can "scrub" across the top of the valve stem, these adjusters feature a swiveling head. This design ensures that the contact surface remains flat against the valve stem throughout the entire rocker arm sweep, significantly reducing side-loading and premature wear on your valve guides and stems.

Vehicle & Engine Fitment

This set of 8 adjusters is designed for high-performance and stock air-cooled applications, including:

• Volkswagen Type 1 (Beetle, Karmann Ghia, Thing)
• Volkswagen Type 2 (Bus/Transporter)
• Volkswagen Type 3 (Squareback, Fastback, Notchback)
• Dune Buggies, Sand Rails, and Trikes using VW-based engines

These are compatible with most stock and aftermarket rocker arms designed for standard thread adjusters. They are particularly essential when running high-lift camshafts where valve train geometry becomes more aggressive.

Appletree Pro Tech Tips

Tip 1: Verify Valve Cover Clearance. Because swivel foot adjusters are physically taller than stock adjusters, they often require more internal room. Always "dry fit" your valve covers and rotate the engine by hand to ensure the adjusters do not strike the inside of the cover. If clearance is tight, you may need to use rocker shaft spacers or high-clearance bolt-on valve covers.

Tip 2: Initial Lubrication is Key. During installation, apply a high-quality assembly lube or molybdenum grease into the "cup" or ball-joint area of the swivel foot. This prevents "dry" movement during the first few seconds of engine startup before the oiling system provides adequate lubrication to the top end.

Tip 3: Account for Pushrod Length. Due to the added thickness of the swivel head, your effective rocker arm geometry will change. You may find that you need slightly shorter pushrods to maintain the correct 90-degree geometry at half-lift. Always use a pushrod length checker during assembly to ensure your valve train is perfectly aligned for maximum power and reliability.
