Comp Cams 'Xtreme 4x4' Hydraulic Flat Tappet Camshafts

Big Torque Cams!

Four wheel drive engines have special needs and requirements that most street performance camshaft just can't properly statisfy. Comp Cams Xtreme 4x4 camshafts produce tremendous off-idle torque and throttle response as well as big torque throughout the entire operating range without sacrificing necessary vacuum. We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs.

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
