description

This reman camshaft assembly follows Cat Reman rebuilding workflow, including fluorescent penetrant inspection, straightening, intake cam fine grinding and hardness sampling test. It adopts dedicated intake lift profile to control intake valve opening timing precisely, improve air charging and boost combustion efficiency. The kit includes camshaft body and thrust plate, no separate thrust part required. It is made of tough forged alloy steel, cam lobes are induction hardened, journals reground to OEM tolerance. It is intake-only design, different profile from exhaust camshaft 20R-4756, not interchangeable individually. Verify engine serial number before ordering.
