The DK-GML5P-CHL arrives fully assembled with a complete new valve train, so you can get your truck back on the road faster. It includes new black nitride-coated valves, valve springs, valve seats, valve seals, retainers, and keepers — everything you need for a confident bolt-on installation.

Key Features & Benefits

• Fully Loaded & Ready to Install — Saves hours of labor. No need to disassemble, inspect, or reassemble valve train components from your old head.

• Precision CNC Valve Job — Ensures excellent valve-to-seat sealing and long-term reliability under heavy towing and high-load conditions.
• Black Nitride-Coated Valves — Added durability for demanding diesel applications.
• No Core Charge — Brand new part means you keep your old head (or sell it/scrap it). No return hassles or extra fees.
