The JIMS rocker (manufacturer ref. 2456-1) is a hydraulic tappet designed for Harley engines and vintage/classic machines, touring and roadster. Made from steel, it features the Big Axle™ Powerglide™ geometry with a micro-finished bore and precision machining aimed at reducing operational clearance (0.0002"). Ideal for riders looking for a robust replacement part specifically designed for roller architectures.
This part is particularly suitable for Harley Davidson Softail 1340 models (e.g. FXSTS, FXSTB, FXST 1999) — please check compatibility with your machine before installation. A reliable replacement part for roller tappets, it fits into camshafts and timing systems that accept tappets of this diameter and style.
