Engine Rebuild Kits

Today’s engines are extremely durable, and last much longer than their forebears, but anything mechanical eventually wears out. If your engine is consuming oil because of worn rings or valve guides, down on power because of poor ring and valve seal and worn cam lobes, or has low oil pressure, a complete overhaul may be in order. You can choose to go with a remanufactured engine, or restore your existing powerplant with an engine rebuild kit.

The content of a rebuild kit varies according to application, the needs of the engine, and the goals of the engine builder. The most inclusive kits are master rebuild kits, which usually consist of a complete gasket set, pistons, rings, main, rod and cam bearings, camshaft and lifters, a timing set, oil pump, freeze plugs, and even Plastigage and assembly lube. Most kits come with standard size parts unless you specify oversize pistons and undersize bearings. It’s common practice to have the block bored oversize, usually +0.030”, and the crank journals ground 0.010”, to obtain the right clearances.

There are a myriad of less comprehensive kits, which enable you to get just the parts that you need. For example, if you’re sourcing your own pistons or if inspection reveals only a minor freshening of the bores is needed, than a re-ring kit may suffice. Or if you’re getting a crank kit, which includes main and rod bearings, then you won’t need a rebuild kit with those parts. The makeup of gasket sets also differs. A top end set includes head gaskets, and intake, exhaust, and valve cover gaskets, and if a conversion set is added it provides all the gaskets needed for the lower end, including rear main seal.

Even a standard rebuild with OE replacement parts will awaken the horsepower in a tired mill. But whether you’re doing a complete engine overhaul or just repairing specific areas, we have the parts that can upgrade power and reliability in the process. From mild to wild, complete engine rebuild kits with forged pistons and performance camshafts, to balanced rotating assemblies and stroker kits, we have it all. If you want a significant upgrade in power over factory, we offer complete rotating assemblies that include pistons, rings, connecting rods and crankshaft. Many of these come balanced to ensure smooth operation at all RPMs.

Street/strip assemblies generally feature cast cranks with forged I-Beam rods and hypereutectic pistons, while assemblies designed for competition have forged cranks, forged H-Beam rods and forged aluminum pistons. Couple one of these with a cam and kit and get ready for tire shredding fun! When it comes to making horsepower, there’s no substitute for cubic inches. But instead of trying to engineer an expensive engine transplant, you can gain cubic inches within your engine’s existing architecture with a stroker kit. A stroker kit consists of a longer stroke crankshaft and carefully matched oversized pistons and connecting rods. Stroker kits are available for select applications and the increase in size depends on the engine, but in some cases it can be as much as 45 cubic inches!
