Skunk2 Honda/Acura VTEC B Series Spring Type Lost Motion Assembly Kit

If you're working on a Honda B-series VTEC engine, like those found in your 1992-2001 Acura Integra, you might be looking to upgrade your camshafts. When you do, especially with higher lift cams, you'll want to replace the factory piston-style lost motion assemblies (LMAs) with these improved spring-type units from Skunk2 Racing. These assemblies put pre-load on the VTEC rocker arm when VTEC isn't engaged, which helps prevent the common rattling noise that can happen when the factory piston seizes due to oil contaminants over time.

Skunk2 makes these LMAs from chrome silicone steel, a strong material chosen for its resilience. They've used advanced design tools like 3D CAD and FEA to optimize the spring's performance, and the hardened tip adds extra durability where it counts. These springs are even 3 percent stiffer than the ITR springs, offering a solid option for your build. They're specifically recommended when installing aftermarket camshafts and are a must-have if your camshaft lift exceeds 0.490 inches.

This kit includes 8 assemblies, enough for a complete 4-cylinder B-series VTEC engine. They're compatible with all camshafts, but are particularly beneficial for those with higher lift profiles.
