We specialize in Cat C15 & C18 Acert & Non Acert cylinder heads. Our cylinder heads are similar to genuine Caterpillar cylinder heads. We proudly sell these cylinder heads with One Year Warranty. In order to reduce failure or cracks on the cylinder head due to overheating we manufacture these heads with 5% nickel in the casting, we enlarge the coolant passages and fortify the inner ribs. We assure 100% satisfaction.
