1.25:1 Rocker Arm Set - Type 1 Engines

Forged 1.25:1 ratio rocker arm set for Volkswagen Type 1 aircooled engines. One of the simplest and most effective bolt-on upgrades for increasing valve lift and improving engine performance without increasing camshaft duration.

These ratio rockers increase valve lift over standard rockers, helping improve cylinder filling and overall horsepower while maintaining good drivability. Suitable for both standard and performance engine builds and can also be used with camshafts specifically designed for 1.25:1 ratio rockers.

Manufactured from forged material for improved strength and durability over cast rocker arms. Designed for use with standard rocker shafts, although bolt-up rocker shafts are strongly recommended on higher performance engines.

For best results we recommend fitting 8mm swivel foot adjusters to reduce valve train wear and improve geometry.

When fitting to stock or modified engines it is important to always check valve geometry, rocker cover clearance and pushrod tube clearance during installation.
