Remanufactured Engines are fully disassembled; heads, blocks, cranks & cams are machined & wear parts are replaced. Each engine is individually tested after assembly to assure compression, oil pressure and water jacket integrity.

Product Features:

Each engine we remanufacture is essentially reverse engineered – in part to discover original factory deficiencies. If possible, our seasoned R&D personnel & QC experts make improvements. Why shouldn’t our engine last longer than your first?
Engines come with installation gasket set & oil pump unless noted otherwise. If we have important installation information it will be included on tags or in the paperwork packaged with your engine.
Engines are securely packaged in a recyclable container that will also protect your core on the return trip. Our nationwide warehouse network means speedy delivery.
Each engine is remanufactured with quality OE level components not “white” box generic parts that may or may not satisfy your needs and expectations. When you use the best you get the best results and satisfaction.
