KMJ Performance is proud to sell the Professional Products LT-1 Chevy PowerForce Harmonic Balancer!  These dampers will not fit 1996-97 LT4 Corvette and Camaro or 1992-96 LT1 Corvette. These dampers do fit 1993-97 LT1 Chevy Camaro, Pontiac Firebird, 1994-95 Chevy Caprice, Impala, and Buick Roadmaster. To identify an LT4 from an LT1, the LT4 VIN number has the eighth digit as a "5" and the LT1 has it as a "P." This damper includes a high strength steel hub, spacers for various engine applications and high quality damper to hub attachment bolts in two different lengths. It is highly recommended to use a new factory crankshaft bolt, GM #9440024. Ths damper has a keyway and a supplied key plus 60° of timing marks. The stock damper does not use a key, but the crank has a keyway in it. For high performance applications, use of the key is recommended.

Advantages of Professional Products Dampers

Price: Yes you can buy less expensive dampers but not at this quality level. We have tested a number of lesser priced dampers. In most instances they are not accurately balanced and in every case that we tested, the external balance was not only off, it was in the wrong position.

Applications: We have yet to find a competitive company that offers the wide range of applications that we have. We have dampers for nearly every performance engine currently available.

Universality: We are able to fit more applications with fewer part numbers than any other damper manufacturer. As a result of some of our universal features, we fit engines that on one else does.

Quality: Despite our extremely attractive prices, the quality of our dampers is equal to or, in most cases, exceeds that of any other harmonic damper manufacturer. You wont find any damper that is more accurately balanced or more closely machined than what you will find in the line of Powerforce and Powerforce+Plus dampers.

Features: The Professional Products line of dampers offers features not found with any other damper manufacturer. For example, our small block Ford dampers are made to the early short length. This permits the engine swap of 1982 and later 5.0L engines (with the 50 in. oz. damper) into early Mustangs or street rods where the longer late damper might not fit. We offer a line of inexpensive spacers that allow the use of a wide range of pulleys that permit proper belt alignment. Additionally our SB Ford dampers have both three and four bolt pulley patterns to accept either early or late pulleys. They also have three sets of easy to read timing marks which will align with any of the various timing pointer locations that Ford has used. Our small block and big block Chrysler plus our AMC dampers all come with extra counterweights which allows the same damper to fit a wide variety of different model engines. Some of our Chrysler weights allow fitment to limited production engines that other damper manufacturers have chosen to completely ignore.

Easy to Read Timing Marks: Our dampers all feature clear, white, easy to read timing marks against a painted black background. In addition, most models have engraved marks every 90° which many engine builders find to be a very important feature.

Warranty: Unlike many of the competitive dampers, we have a full one year limited warranty on both our street and race dampers. Most companies do not warranty any product used in racing.

Bonded Construction: All of our dampers feature a bonding process which adheres the elastomer to both the O.D. of the hub and the I.D. of the inertia ring. Through subsequent research and develoment we have perfected a new process that uses a stronger adhesive along with an improved elastomer that creates a much stronger bond. It now takes twice the force to separate the hub from the ring as it did with our previous bonding procedure. Our current design is practically indestructible.
