    Product Description

    Brian Tooley BTR .685" Dual Valve Spring Kit with Titanium Retainers

    Fits 1997-2013 LS Based Gen 3/4 Engines

    When you decide to take a walk on the wild side and exceed the .660” limit of most popular spring kits, the next step is BTR's .685” Spring Kit. A higher spring rate and titanium retainers will ensure valvetrain stability with radical camshafts. This kit does NOT fit LS9 engines. LS7 engines will require shims. 

    The kit includes: Dual .685" springs, titanium retainers, spring locating seats, seals, and locks.
