Push your LS build to the limit with the Brian Tooley Racing Stage 4 V2 Camshaft Kit, designed with one goal in mind—maximize naturally aspirated power. Featuring a 233/243 duration, .636”/.636” lift, and 111 LSA, this hydraulic roller cam delivers an aggressive lope at idle and brutal top-end power from the midrange all the way to 7,000+ RPM. Spintron-tested and dyno-proven, this cam is BTR's most aggressive offering for cathedral-port LS builds. Ideal for LS1, LS2, LS6, LQ4, LQ9, and L33 engines, this grind demands proper valvetrain support—dual valve springs, hardened pushrods, and a 3200+ stall torque converter for automatic transmissions. When paired with ported heads, long-tube headers, and a free-flowing intake, this cam delivers 500+ WHP with no boost required. Whether you're daily driving a street beast or running heads-up at the strip, this cam brings signature BTR attitude and unmatched performance to your build.
