Upgrade your valvetrain with these precision-engineered billet alloy rocker shaft spacers. Hand-crafted in-house, these spacers replace original fragile springs to provide a more stable and reliable platform for high-performance and racing engines.

Product Specs

• Material: High-grade Billet Aluminium
• Manufacturing: Machined and hand-finished in-house
• Design: Precision-tolerance spacers for rocker shaft alignment

Why Choose Billet Alloy Spacers?

• Enhanced Stability: Replaces the standard spring spacers which can allow rockers to move laterally under high RPM, ensuring consistent valve timing.
• Superior Durability: Machined from high-strength billet aluminium to resist wear and thermal deformation in the harsh environment of the cylinder head.
• Reduced Friction: Provides a smooth, precise mating surface that keeps the rocker arms perfectly centred over the valve stems.
• Specialist Craftsmanship: Each set is hand-finished in our own workshop to ensure the highest quality control and a perfect fit for your specific engine.

Installation Tip: When installing these spacers, ensure your rocker shaft is clean and free of scoring. We recommend checking the side-clearance of each rocker arm once the shaft is torqued down to ensure smooth, unhindered movement.

Lead Time: Each set is hand-made to order. Please allow 2–3 working days for dispatch.
