Revolutionary GM Gen V Camshafts (LT1/L83/L86) from COMP Cams® are designed to work with the direct injection (DI), variable valve timing (VVT) and Active Fuel Management (AFM) lifters featured in GM’s new Gen V V8 engine. This means that these new XFI™ series hydraulic roller cams allow users to leverage OE technology for performance gains. Gen V Cams feature four different lobe profiles to not only allow AFM-lifter compatibility, but also to optimize intake and exhaust valve opening/closing events. COMP Cams® GM Gen V Camshafts also increase torque and power throughout the entire RPM range, while providing excellent responsiveness and mid-range power over stock for across-the-board gains. The cams must have the COMP® Phaser Limiter Kit (Part # 5456), which limits the range of camshaft movement from 62 to 22 crank degrees. Thus they require VVT program tuning. COMP Cams® GM Gen V Camshafts are available for stock to highly modified applications. Options for use include the 2014 and newer C7 Corvette, Chevy SS, Chevy Silverado and GMC Sierra, along with the 2015 editions of the Cadillac Escalade, Chevy Suburban/Tahoe and GMC Yukon/Yukon XL. The smaller cams are an ideal choice for L83 and L86 truck engines, while the larger versions are perfect for high performance LT1 applications. AFM-delete custom grind versions are also available.
