Description

The Skunk2 Racing Lost Motion Assembly (LMA) Kit is a direct replacement for factory components in Honda B and H Series VTEC engines. Its function is to maintain the proper position of the center VTEC rocker when disengaged and provide additional spring force when engaged. This kit is designed with increased travel to accommodate high-lift camshafts, preventing factory LMAs from binding and wearing down the VTEC lobe.
