    Four wheel drive engines have special needs and requirements that most street performance camshafts just can't properly satisfy. Comp Cams Xtreme 4x4 cams produce tremendous off-idle torque and throttle response as well as big torque throughout the entire operating range without sacrificing necessary vacuum.

    Features:
  • Improved throttle response and increased low & mid-range RPM horsepower for towing and off-road
  • Designed for use with common restrictive factory exhaust systems, including OEM exhaust manifolds
