These springs ensure a force suitable for high lift cam profiles, allowing reliable control of valve closure at high RPM. Installation does not require complex machining but does impose a precise adjustment of valve clearance to ensure the safety and longevity of the timing system. Particularly suitable for builds on classic Harley-Davidson heads (e.g. FXWG, FXSB, FXRT 1340 models from 1984 mentioned as examples).

Before installation, check compatibility with your camshaft and follow the clearance tolerances recommended by the manufacturer or your builder. This ANDREWS 272110 pack is aimed at riders looking for a reliable part to optimise lift while maintaining a simple installation.
