GPI L86 (6.2L) DI Truck High Lift Cams - STG1 (2014 GMC Sierra 1500 6.2L / Chevy Silverado) - L86HL1
High-Lift Performance Camshaft for 6.2L DI Trucks
The GPI L86HL1 STG1 camshaft is engineered to deliver a clean idle, exceptional low-end torque, and impressive top-end efficiency for your 6.2L Direct Injected GM Truck. Designed for owners who want noticeable performance gains without compromising daily drivability, this STG1 cam is the ideal upgrade for lightly modified trucks.
Built around a proven high-lift profile, the L86HL1 requires dual .660" valve springs and a GPI phaser limiter. It was developed to work seamlessly with stock torque converters and stock heads with no milling, making installation straightforward while delivering a dramatic improvement in throttle response and pulling power.
Versatility for N/A or Future Boost
Although optimized for naturally aspirated applications, the linear power curve of the L86HL1 makes it an excellent match for centrifugal supercharger setups. This is a strong choice if you want more power today and plan to add boost later - without the need to swap cams down the road.
