DescriptionCHE Precision LS Trunnion Conversion Kits are designed for use with 3/8 or 7/16 studs on a small block or big block Chevy engine. The LS rocker arms are lighter, well respected for their design, and will help improve the stability of your valve train. In addition, these rocker arms have a ratio of 1.7:1 for the small block Chevy and 1.8:1 for the big block Chevy, which increases valve lift and changes duration. By increasing the ratio with the CHE Precision Conversion Kit, the valve opens farther and changes duration without having to upgrade your camshaft, resulting in improved airflow and more performance from your engine.
