The Skunk2 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.
Each Skunk2 Lost Motion Assembly is manufactured exclusively from chrome silicone steel using the latest 3D CAD (Computer Aided Design) modeling and FEA (FiniteElement Analysis) to ensure maximum optimization. Each chrome silicone steel spring features a hardened tip for added durability. Skunk2 engineers then tested and proved their design on the engine dyno as well as the race track.
The Skunk2 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 Skunk2 Pro Series and other 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 Skunk2 Lost Motion Assembly springs are 3 percent stiffer than ITR springs.
Note:
This is not compatible with B-Series NON-VTEC engines.
No shims required.
