COMP Cams XFI Xtreme Truck Camshafts

Release the incredible horsepower and torque hidden inside your vehicle's engine with COMP Cams XFI Xtreme truck camshafts. Available in three different profiles (XFI 260, 261, and 266), they utilize advanced camshaft technology used in fuel injected engines to deliver improved throttle response and better mid and upper rpm power. COMP Cams XFI truck camshafts (for the GM Gen III engines) are compatible with the factory computer systems and wiring, but deliver the best performance when used with upgraded COMP Cams valvetrain equipment, including valve springs, retainers, and locks. Computer tuning is required; use a Fast Flash Cam Tuner Programmer for best results. Show Less
