Crafted of premium quality spring wire and precision wound to tight tolerances, Sure Seat Valve Spring sets are designed to be used on original equipment heads with the installation of Edelbrock Performer-Plus, Performer RPM and Torker-Plus camshafts. These high-performance springs are also used on Edelbrock Performer and RPM cylinder heads. The #5900 Series valve springs are manufactured for use with OEM valve rotators. These complete Valve Spring Kits include non-rotator valve springs, valve spring retainers and matching valve stem locks. For preservation of camshaft warranty, use only those springs recommended by Edelbrock for each camshaft application.
Crafted of premium quality steel, machined and strengthened through heat treatment, these retainers have a finish of black oxide for protection against rust and corrosion. Chevrolet LS1 retainers come in steel or lightweight titanium. Sold in sets of 16.
