GPI L86 (6.2L) DI Truck Low Lift Cams - STG3 (2014 GMC Sierra 1500 5.3L / Chevy Silverado) - L86LL3
Stage 3 Low Lift Camshaft for Maximum 6.2L DI Truck Performance
The GPI L86LL3 is the most aggressive low lift option for the L86 6.2L Direct Injected GM truck platform, built for enthusiasts who want the strongest top-end power and torque gains available without stepping into high lift territory. This cam delivers a noticeable performance jump over STG1 and STG2 while still offering the durability and smooth valvetrain behavior expected from GPI's low lift designs.
Despite its increased output, the L86LL3 still maintains the quiet, reliable operation characteristic of all low lift GPI cams. It thrives in trucks with supporting modifications and an upgraded converter, and because centrifugal blowers mimic NA power curves, it also works exceptionally well in centrifugal supercharged builds.
