GPI L86 (6.2L) DI Truck Low Lift Cams - STG1 (2014 GMC Sierra 1500 5.3L / Chevy Silverado) - L86LL1
Stage 1 Low Lift Camshaft for 6.2L Direct Injected GM Trucks
The GPI L86LL1 Stage 1 low lift camshaft is engineered for truck owners who want improved performance without sacrificing drivability. Designed specifically for the L86 6.2L Direct Injected GM truck platform, this cam delivers better throttle response, increased torque, and stronger midrange - all while maintaining excellent idle quality and compatibility with the stock torque converter.
This low lift design provides quiet, smooth valvetrain operation and long-term durability. It's ideal for trucks with minimal modifications and works exceptionally well with naturally aspirated setups or centrifugal superchargers thanks to their similar linear power curve.
Required Components & Install Notes
As a low lift LT truck camshaft, the L86LL1 requires:
- Stock LT1 valve springs
- GPI 4° Phaser Limiter
- No cylinder head milling without verifying PTV clearance
This cam is specifically designed to drop into lightly modified or near-stock trucks with minimal supporting upgrades.
Optimized for NA or Centrifugal Blower Builds
Although this camshaft is primarily crafted for naturally aspirated engines, the L86LL1 also performs extremely well with centrifugal blowers due to the matching power curve. It's an excellent choice for owners who may decide to add boost later.
