Skunk2 Lost Motion Assembly For Honda B-Series

Skunk2 is proud to introduce its Lost Motion Assembly Kits for Honda's B-series VTEC engines. Skunk2 Lost Motion Assemblies will fit any B-Series DOHC VTEC engine (Type-R/GSR B16A, B17A, B18C). The Skunk2 Lost Motion Assembly is an advanced spring device designed to pre-load on the centre 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 idling. Each Skunk2 Lost Motion Assembly is manufactured exclusively from chrome silicone steel using the latest 3D CAD (Computer-Aided Design) modelling and FEA (finite element 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 and the race track. The Skunk2 Lost Motion Assembly Kit replaces the factory piston-style LMA design with an improved design 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) are compatible with all camshafts. When using camshafts with a +12.5mm lift, LMA's are an absolute must, and Skunk2 Lost Motion Assembly springs are 3 per cent stiffer than ITR springs.

Features:

• Manufactured from Chrome Silicon Steel
• Replaces factory piston-style assembly
• Allows more LMA compression before bind
• Needed for camshafts with lift above 12.5mm
• Hardened tips for longevity and durability
• Fits all B-series VTEC cylinder heads

Note:

• This is not compatible with B-Series NON-VTEC engines.
• No shims required.
