The COMP Cams CS 280XFI HR‑13 camshaft kit arrives as a full K‑Kit—camshaft, lifters, valve springs, retainers, locks, valve stem seals, timing chain set, assembly lube for flat tappets, decals and instructions—for complete installation. Targeted at hot‑street builds, it requires intake, gear and exhaust upgrades and prefers a 2500+ stall converter to reach its potential.
