TRP Cathedral High Lift Stage 1 Cam is best suited for those who want a nice bump in tq/hp without sacrificing drivability or low-end torque in their 99-13 GM Truck or SUV with 4.8/5.3 and 99-07 car and truck 5.7/6.0 with cathedral port cylinder heads.
TRP camshafts are ground in USA on USA made 5150 cores that have a smooth lobe design for quiet valvetrain operation and longevity. The idle quality will be smooth with a mild lope, and the drivability will be great pulling out to 6500 RPM.
