BLOX Racing LMA (Lost Motion Assembly) is a necessary upgrade when your OEM lost motion assembly has become old and worn and starts making clicking sounds. Although the OEM had introduced a better design in more recent engines, it is still not considered a cost effective replacement. BLOX Racing's LMA kit is your cost effective and high performance solution when the factory pieces have become old and worn and, definitely when upgrading to high lift camshafts. Each assembly is manufactured using the same high quality materials as its valve springs for durability and reliability. BLOX Racing LMA is sold as a kit with 8-pieces. Available for Honda/Acura B-series DOHC VTEC engines. No shim/spacer/washer required.
