99-13 GPI – Cam Package (GM Low Lift 1 LS Camshaft 4.8L / 5.3L / 6.0L)
 
The LLT1 camshaft was specifically designed for trucks that are used as trucks. They offers stable idle, excellent low end torque (1,750 rpm and up), and smooth lobe design for quiet valve train operation and longevity. We designed this cam for use in trucks with minimal modifications.
This cam does not require an upgraded torque converter or exhaust.
