COMP Cams XFI AFM Hydraulic Roller Camshaft, 274PIIHR18 (2014-2015 GM LT1/L83/L86 Gen V 8 Cylinder)

Revolutionary GM Gen V Camshafts from COMP Cams® are designed to work with the direct injection, VVT (Variable Valve Timing) and AFM (Active Fuel Management) lifters featured in GM’s Gen V (LT1/L83/L86) V8 engine. This means that these XFI™ series hydraulic roller cams allow users to leverage the OE technology for performance gains. Gen V cams feature four different lobe profiles to both create AFM compatibility and optimize intake and exhaust valve opening/closing events. COMP Cams® GM Gen V Camshafts also increase torque and horsepower throughout the entire RPM range, while providing excellent responsiveness and mid-range power over stock for across-the-board gains.

These cams must have the COMP® Phaser Limiter Kit (Part #5456), which limits the range of camshaft movement from 62 to 22 crank degrees thus requiring VVT program tuning. COMP Cams® GM Gen V Camshafts are available for stock to highly modified applications. The smaller cams are an ideal choice for L83 and L86 truck engines, while the larger versions are perfect for high performance LT1 applications.
