What's the difference between and inframe and overhaul engine kits?

All inframe and overhaul kits come with cylinder kits, rod bearings and main bearings. The main difference is in the gasket set. In an inframe rebuild you do not remove the crankshaft or front cover. Because of this, the inframe kit will not include gaskets for the front or rear structure of the engine. The front and rear crankshaft seals are also not included in inframe engine kits. In fact, the only lower gaskets you would get in an inframe kit would be the oil pan gasket set.

In cases where you require timing cover gaskets, crankshaft seals and/or water pump gaskets, you would need an overhaul kit. Overhaul gasket sets are much more complete and are used when the engine is disassembled completely.

Other gaskets or gasket sets you might need to purchase in an overhaul that would not be include are oil cooler installation, fuel injectors and fuel injection pump & lines. If they aren’t included in your inframe or overhaul kit, we can add them for you.

On top of the high cost for labor, high cost for parts is the last thing you want to worry about during an inframe or overhaul. Agkits is your alternative. We have a huge inventory of engine inframe and overhaul rebuild kits for your truck at competitive prices.

Remanufactured Cylinder Heads

A remanufactured cylinder head is a head that has been rebuilt with parts that are still serviceable. Some cylinder heads have been welded or repaired. All cylinder heads are pressure tested to assure a leak-free casting. New valve seats have been installed when needed. All cylinder heads have a three angle valve cut with a blade type seat cutter. Valves are ground to factory specifications or replaced if necessary. Valve springs are checked. Cylinder heads are painted, resurfaced, and reassembled.
