The Brian Tooley Racing .660" LS Dual Valve Spring Kit with Titanium Retainers is a high-performance upgrade designed for Gen 3 and Gen 4 LS engines. Featuring dual springs with seat pressures ranging from 155 to 400 lbs and a max lift of .660", this kit prevents valve float and ensures stable valvetrain operation at elevated RPMs. Titanium retainers reduce reciprocating mass, enhancing RPM capability and durability. Ideal for aggressive camshafts in street, strip, and boosted LS builds, it offers a direct drop-in fit for all 15° LS heads, backed by Brian Tooley Racing’s proven expertise.
