Overview

The GSC Power-Division Conical Valve Spring Kit (GSC5076) is engineered for Subaru DOHC EJ Turbo engines. This comprehensive kit includes 16 conical valve springs, 16 titanium retainers, and 16 chromoly spring seats, designed to precisely manage elevated RPM and boost pressures.

Featuring a tapered coil profile and progressive spacing, the conical spring geometry inherently absorbs valvetrain shock and suppresses harmonics. This design enhances stability, reduces wear, and extends component life, particularly in high-output turbocharged applications. Each spring undergoes a patented multi-step heat treatment and a super-polished surface finish, ensuring durability and support for aggressive cam profiles and high RPM operation.

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.
