Valve Spring Locators, Spring Seat and Seal Kit for Chevy LS Series 5.3L and 6.0L, Kit

As with all other areas in the valvetrain, the area where the spring sits also takes a beating. The old standard shims and/or seats simply will not hold up to the extreme pressures and high rpm found in today's performance engines. COMP Cams valve spring locators solve this problem and eliminate failures.
