2007-2009 GM 4.8L VORTEC/LS 3 YEAR WARRANTY

Cylinder Heads are resurfaced to assure a proper sealing surface with the block and a finish compatible with today’s new gasket materials. New valves, springs, rockers, retainers, locks, seals, and if needed seats and guides, are installed. Valve height is miked and every head is vacuum tested to assure correct valve seating. Every cylinder head recieves a premium 3-angle valve job.

Cylinder Blocks are magnetic particle inspected for cracks or imperfections. Cylinders are bored and honed and inspected to precise tolerances. Torque plate honing is performed on specific engines to eliminate cylinder head distortion after the head is bolted and torqued to the block. This process eliminates a major cause of engine blow-by. Block surfaces are machined and then inspected to ensure proper finish.

Camshafts are inspected and precisely machined to provide correct lift. We only use new camshafts, lifters, and camshaft bearings in all our assemblies.

Connecting Rods are machined to O.E.M. specifications and honed to the standard diameter of original equipment for even distribution of stress on the bearings. New bushings are installed and machined in all bushed rods. Every rod is carefully inspected for bend and twist as are all remanufactured parts.

Remanufacturing
To remanufacture is to make as close to new as possible. Most wearable parts are automatically replaced. All core material is closely inspected and checked against original equipment specifications for correct dimensional tolerances. Replacement parts are new or requalified. All parts are made in the same production processes as original equipment. Testing is performed to manufacturer specifications and original production standards. All remanufactured parts are also tested to the highest standards.

New Parts
Our rebuilt and remanufactured engines receive a standard set of new parts such as new pistons and rings, bearings, gaskets and seals, liners, camshaft and lifters, valves, springs, retainers, locks and premium hardware. All variable valvetrain and cylinder deactivation mechanisms are supplied by the original oem dealer, not an aftermarket or overseas supplier. Our commitment to using new oem or better parts assures consistent performance and reliability throughout the life of all engines that leave our facility.
