Product Description
Brian Tooley Racing BTR .625" Lift Beehive Valve Spring Kit – BTR-SK018
Fits 1997–Newer LS-Based Engines – 4.8L, 5.3L, 5.7L, 6.0L, 6.2L
The Brian Tooley Racing BTR-SK018 beehive valve spring kit is a proven, budget-friendly choice for camshafts with less than .625" valve lift. Designed to work with BTR's beehive locators and factory retainers/locks, this kit delivers reliable performance for both street and limited racing applications. Tumble polishing reduces stress risers and provides a clean, high-quality appearance. Extensively tested on BTR’s in-house Spintron and engine dyno, these springs are built for long-term durability.
BTR recommends this kit for use with their LS truck camshafts in rectangle port 6.0L/6.2L engines (L92, L94, L96, L9H, L76, LY6) due to their heavier valves. Note: Cannot be used with OEM hat-style valve seals.
