Description

The Brian Tooley Racing SK001 is a Platinum Dual Spring Kit designed for GM LS-Series engines. This kit offers a 380 lb/in spring rate and has a coil bind of 1.070 inches with an outside diameter of 1.300 inches. It comes complete with locks, steel retainers, Viton seals, and seats, making it a comprehensive solution for engine upgrades. This kit is engineered as a "drop-in" for 15° LS heads and is typically compatible with LS7 heads when used with a .030” shim (Part number SS030). However, it is explicitly stated that this kit will not fit LS9 applications. Brian Tooley Racing, based in Kentucky, is known for designing and producing performance components for popular engines like LS, LT, Godzilla, and Hemi, with an emphasis on optimizing performance while maintaining reliability, all precision-machined in the USA.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
