GPI High Lift LS Camshaft for GM Trucks (4.8L / 5.3L / 6.0L / 6.2L) - HLT2
High Lift Truck Cam for Maximum Power Gains
The GPI HLT2 High Lift LS Camshaft is engineered for truck owners who want stronger mid-range and top-end performance while still retaining excellent low-RPM torque and street manners. Designed for 4.8L, 5.3L, 6.0L, and 6.2L LS engines, this cam delivers a stable idle, upgraded torque from 2,250 RPM upward, and long-term valvetrain reliability thanks to its smooth, quiet lobe profile.
Ideal for trucks with minimal modifications, the HLT2 does not require an upgraded torque converter - though GPI does recommend one for maximum performance on 5.3L applications.
