Product Description

Brian Crower BC1030 dual valve springs are engineered for high-RPM Honda H22 and Nissan SR20 engine builds. Wound by PAC Racing from the highest-grade chrome silicone alloy, these springs deliver consistent seat and open pressures for reliable valve control with aftermarket camshaft profiles. The dual spring design provides the pressure needed to prevent valve float at elevated RPMs while supporting cam lift up to 0.510". An ideal upgrade when installing performance camshafts or building a high-revving naturally aspirated or turbocharged SR20 or H22 engine.
