BLOX Racing Lost Motion Assembly (LMA) springs are 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.

8-piece kit.

Engine Application: All B-series VTEC engines. No shim/spacer/washer required.
