Skunk2 LMA Assembly

    Skunk2 is proud to introduce its Lost Motion Assembly Spring  Kits for the Honda B16A/B, B17A, B18C VTEC engines or B Series engines  using the VTEC cylinder head. The Skunk2 Lost Motion Assembly is an advanced spring device that is  designed to put pre-load on the center portion of the VTEC rocker when  it is in the unlocked position (VTEC is disengaged). Once RPM range that  VTEC engages, the Lost Motion Assembly (LMA) will compress just like  the valve springs and similarly to valve springs... LMA's will over time  loose their ability to function properly, become contaminated, and/ or  not be able to accommodate the camshafts lift and will need to be  replaced. Skunk2's Lost Motion Assembly Springs are manufactured exclusively  from chrome silicone steel using the latest 3D CAD (Computer Aided  Design) modeling and FEA (Finite Element Analysis) to ensure maximum  optimization. The Skunk2 Lost Motion Assembly Kit replaces the factory  piston-style LMA design with an improved design commonly found in newer  generation Honda engines and incorporate a hardened tip for added  durability. Skunk2 recommends replacing the LMA's when installing aftermarket  camshafts as a preventive maintenance measure but requires replacement  when installing Skunk2 Pro and Ultra Series camshafts or any camshafts  with a lift greater than 12.5mm.
