Tick Performance proudly presents our .660" Lift Dual Valve Spring Kit for all LSx Engines, featuring only the finest components and assembled here in-house! This high quality setup is included in each of our Elite Series Camshaft Packages, and features the following components:
- 16x PAC Racing #1904 Dual Valve Springs rated to .660" Lift
- 16x Lightweight Tool Steel or Titanium Retainers
- 16x Spring Locators for Stock Guides or Aftermarket Bronze Guides (your choice)
- 16x Valve Locks

One of our favorite aspects of this kit is that the Tool Steel retainer is the lightest steel retainer made for 1.300" dual springs, only weighing 13.9 grams or 16.4 grams with locks. Those looking for the lightest valvetrain possible should upgrade to the optional Titanium retainers available at checkout, which are the lightest available for LSx dual springs, weighing in at 8.5 grams, or 11 grams with locks.

.660" springs with shims for LS7
I use these springs as an insurance policy for customers with stock Z06 heads. I've never had a problem. I highly recommend these as a replacement for the stock garbage springs. Thank you Tick, I will be a lifelong customer.
