The Supertech dual valve spring kit for Nissan VG30 is a replacement spring set matched to VG30 engines. Offered as a dual-spring configuration, it is suitable for head servicing or rebuilds where tighter valve control is desired compared with a single spring. Install this kit when refreshing the VG30 cylinder head to restore consistent valve movement and seating for that application.
