Brian Tooley Racing is proud to introduce the next innovation in the GM performance truck industry. Our all new V2 series was born from the demands of an ever changing market. From toy haulers to trucks turned street rods, our V2 truck cam lineup has an answer for your needs. We have partnered with an OEM Tier 1 supplier to supply steel camshaft cores, each V2 cam is born from its own specific cam core. NO GENERIC CORES USED. The end result is a revised camshaft that provides more average torque, higher peak power, and a maximum depth heat treatment for reliability. We grind these camshafts in-house on one of our Landis LT-1 grinders and finish them with an isotropic polishing so they have maximum durability. The Stage 4 grind is a popular choice for those looking to delete DOD/AFM, or just add some pep to your trucks step. With great power gains and driving characteristics, this camshaft works well with 2800-3200 stall torque converters with an aggressive idle. Made in the USA!
