D16 VTEC Lost Motion Assembly

Lost Motion Assembly LMA for Honda D-Series VTEC

The Lost Motion Assembly is an advance spring device that is designed to put pre-load on the center portion of the VTEC rocker when it is in the unlocked position (when VTEC mode is disabled). During extended operating conditions, the contaminants in the oil will more than likely cause the piston to seize resulting in the VTEC rocker rattling when VTEC is not engaging or when the vehicle is in idle.

Lost Motion Assembly (LMA) kit replaces the factory piston-style LMA design with an improved spring design commonly found in newer generation Honda engines. Replacing LMA's are recommended when installing aftermarket camshafts and required when installing high-lift camshafts.

Each Lost Motion Assembly Kit includes a set of 4 assemblies for an entire Honda D-series VTEC engine and are compatible with all camshafts. When using camshafts with +12.5mm lift, LMA's are an absolute must

Each chrome silicone steel spring features a hardened tip for added durability.
