Comp Cams XFI Hydraulic Roller Camshaft, 224/236 D, 222/234 N

*Fits: 2014-2018 Silverado 1500 5.3L or 6.2L

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 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 increase torque and horsepower throughout the entire RPM range, while providing excellent responsiveness and mid-range power over stock for across-the-board gains.

Features:

• Increase Horsepower and Torque throughout the RPM Range
• Enhance Durability and Reduce Load Loss
• Slightly Aggressive Idle
• Perfect for Mildly Modified Applications
• High Quality and Durable Billet Steel Construction

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 PCM tuning. COMP Cams GM Gen V Camshafts are available for stock to highly modified applications.
