Skunk2 Racing High-Lift Lost Motion Assembly (LMA) Kits for the Honda B and H Series VTEC engines are direct replacements for factory lost motion assemblies. The function of the LMA is to keep the center VTEC rocker in the proper position when it is not engaged, and to provide additional spring force to control the added weight off the rocker assembly when it is engaged.
When using high lift camshafts, Factory LMAs may bind and wear down the VTEC lobe. To counter this, Skunk2 Racing designed a spring style High-Lift LMA designed with more travel to accommodate high lift camshafts.
