ScienceofSpeed LMA Kit - Honda VTEC B-Series Engines

Description

The lost motion assembly (LMA) is a spring device that puts pre-load on the center VTEC rocker when it is the unlocked position (when the engine is not in VTEC mode). The original Honda VTEC B-Series LMA is a piston design lubricated by engine oil. Over time, contaminants in the oil cause the piston to seize resulting in the VTEC rocker rattling when not in VTEC (such as while idling). The loose VTEC rocker can result in damage and loud tapping sound while idling.

The ScienceofSpeed LMA Kit replaces the factory piston design with a revised design found in newer Hondas, including 2000-and on NSX.

A coil spring is installed with high precision machined billet stainless steel inserts that sets the coil to the correct engagement height for Honda VTEC B-Series engines. This design is not only more durable, the design allows for an increased 28% stroke and a larger rocker contact patch making it ideal for factory or high lift camshafts.

Kit includes a set of 8 assemblies for an entire Honda VTEC B-Series 4-cylinder engine.
