2188417PEX | Paccar MX13 EPA17 Cylinder Head, New | 2184940PE

Engine / Application
Designed for use in the PACCAR MX13 EPA-17 (HHP) engine (used in Kenworth, Peterbilt, and other PACCAR-powered trucks).

Material & Construction

• Cast from high-strength vermicular iron (or similar advanced iron alloy) to improve crack resistance and thermal stability under heavy duty use. 

• Equipped with Inconel intake and exhaust valves (or other superalloy valves) for superior high-temperature strength, oxidation resistance, and durability in exhaust/combustion conditions. 

• Precision-machined ports, combustion chambers, valve seats, and surfaces to meet strict tolerances for sealing, flow, and thermal balance.

Features & Benefits

• Direct replacement fit — built to match OEM dimensional and mounting specs so that installation is straightforward. 

• Improved thermal endurance — superior materials and design reduce risk of cracking, warping, or failure under sustained high load and temperature cycles.

• Enhanced valve life — superalloy valves hold up better to thermal fatigue, oxidation, and repeated opening/closing cycles.
