New for 2015: 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:

One of our favorite aspects of this kit is that the Brian Tooley Racing Lightweight 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 lighest available for LSx dual springs, weighing in at 8.5 grams, or 11 grams with locks.

This is a drop-in valvespring kit for the following engines: LS1, LS2, LS3, LS4, LS6, L76, L92, L99, LQ4, LQ9, L33, and LSA.  This kit will fit LS7 engines with the proper amount of shimming.  This kit will not fit LS9 engines.

    .660 springs

    Posted by adam dorey on 5th Jul 2018

    I got these as a replacement to the BTR springs I had in my car and I had three that got weak. These look just as good for a few less bucks. They are not polished like the BTR, but the wire in the spring is still ultra smooth with no place for fatigue points.

    Great Product

    Valve springs worked out great for my application. Installed them myself, which is a little bit of a job, but not too bad if you take your time and have the right tools. I'd definitely recommend this product!
