The Brian Tooley Racing truck camshafts are an excellent choice for GM trucks and SUVs equipped with 4.8L, 5.3L, and 6.0L engines. The camshafts are designed to increase power without sacrificing low-end torque and are great choice for heavier vehicles such as: Avalanche, Escalade, Sierra, Silverado, Suburban, Tahoe, Trailblazer, and Yukon.
These camshafts are a 3 bolt design and will fit Gen III and IV engines from 1999 and up. If your engine has AFM or VVT, those will need to be deleted in order for this camshaft to work.
