Supertech is proud to introduce its Lost Motion Assembly Kits for Honda’s B-series VTEC engines. Supertech Lost Motion Assemblies will fit any B-Series DOHC VTEC engine (Type-R/GSR B16A, B17A, B18C).
The SupertechLost 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.
Each Supertech Lost Motion Assembly is manufactured exclusively from chrome silicone steel using the latest 3D CAD (Computer Aided Design) modeling and FEA (Finite Element Analysis) to ensure maximum optimization. Each chrome silicone steel spring features a hardened steel and carbide coated tip for added durability. Supertech engineers improved upon other LMA on the market by applying their decades of spring experience to this quality replacement.
The Supertech Lost Motion Assembly Kit replaces the factory piston-style LMA design with an improved 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 8 assemblies for an entire Honda DOHC VTEC B-Series 4-cylinder engine (Type-R/GSR, B16A, B17A, B18C) and are compatible with all camshafts. When using camshafts with +12.5mm lift, LMA's are an absolute must, and Supertech Lost Motion Assembly springs are 3 percent stiffer than ITR springs.
