Show original supplier description

The COMP Cams dual valve spring kit provides a comprehensive solution for upgrading the valvetrain in GM LS-series engines. Each kit features precision-matched dual valve springs manufactured from Super Clean wire, paired with durable tool steel retainers, valve locks, Viton seals, and steel seats to ensure superior strength and reliability under demanding race conditions. Designed to handle high-performance applications, these springs accommodate a maximum valve lift of .650 inches and feature a spring rate of 400 lb/in. The 1.320-inch outer diameter springs are engineered to maintain consistent valvetrain stability, effectively managing the increased lift and stress common in extreme engine setups. Every component undergoes rigorous quality control testing to meet the high performance standards required by engine builders and competitive racing teams.

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.
