Our Brand New CAT OEM Cylinder Heads feature a genuine CAT OEM casting equipped with brand-new sodium-filled Inconel valves. The sodium-filled design helps transfer heat away from the valve head and through the stem, while Inconel provides excellent strength and durability under extreme exhaust temperatures. All heads are pre-drilled ready for ACERT applications.
​
While lower-cost aftermarket cylinder heads may offer an attractive upfront price, our heads are built around a genuine CAT OEM casting and premium valve components for customers who value proven fit, quality and long-term reliability. When you're investing in a 3406E or C15 engine, the cylinder head isn't the place to compromise. All heads are sold NO-CORE.​
