These two dampers are 6-3/4" in diameter and approximately 1-1/8" thick. These are our most popular dampers for internally balanced small block Chevys. These dampers are dimensionally identical to the stock G.M. 6-3/4" damper. They have 60° of easy to read timing marks and engraved marks every 90 degrees. The Powerforce high performance street model weighs approximately 8-1/2 pounds and the Powerforce+Plus race model weighs 9.3 pounds. The Powerforce high performance street model is also available in a polished stainless steel version suitable for street rods and show vehicles. See listing at the bottom of this web page for details on SB Chevy polished stainless dampers.

This unique design damper is for use on externally balanced small block Chevy engines. This would typically include 383 and 400 cid assemblies. Only a few damper manufacturers offer a small 6-3/4" damper for these engines and those dampers are usually very expensive. Our models, like all of our dampers and other products, are very high quality products at very affordable prices. Note that although this model damper features a bolt-in counterweight, the damper cannot be used without the weight. Due to the windows cut in the front face of the damper, if the counterweight is removed, the damper is still not a neutral balance damper. If you need a neutral balance 6-3/4" damper, use our 80000 or 90000 models.

These are both terrific all around high performance dampers. The 80002 makes a great damper for high performance street applications, and the 90002 is the choice for racing when you want maximum damping to protect the rotating parts as well as the timing gears, timing chain and valve train. Optimum damping means your engine will run as smoothly as possible, and you are getting accurate valve timing. An improperly dampened engine can result in premature crank failure, as well as incorrect valve timing, thus robbing your engine of power. The Powerforce street model is very similar to the much more expensive G.M. Performance malleable iron 8-inch damper except ours is made of stronger nodular iron with more timing marks.

This damper is intended for use on externally balanced 383 or 400 small block Chevy engines. They feature a bolt-in counterweight which can be removed for neutral balance applications. These dampers are actually identical to the 80002 and 90002, except they also include the bolt-in counterweight. Both dampers have 60° of easy to read timing marks and engraved marks every 90 degrees. These are ideal dampers for high performance street or racing applications, and their somewhat heavier weight provides maximum damping characteristics. These dampers, especially the Powerforce damper for high performance street applications, are extremely reasonably priced and yet are very high quality.

This is our smallest (6.1" O.D. x .75" thick) damper for small block Chevys. The high performance street Powerforce model weighs 5.08 pounds, while the Powerforce+Plus race model weighs 5.7 pounds. Both models are made of 1045 steel (all other Powerforce dampers are nodular iron). Keep in mind that the inertia ring weight is what performs the actual damping of the rotating assembly. A light weight damper like this will not achieve the degree of damping that heavier dampers do. But many racers or performance enthusiasts want the lightest damper they can get that will still do the job, and these two dampers fill that requirement. Both models include 60° of timing marks with engraved marks every 90 degrees.

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." Both of these dampers include 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. Both dampers have 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.

Polished Stainless Steel

These dampers are basically the same as our 80000 (350) and 80001 (400) models but made of fully polished stainless steel. They have one engraved TDC mark. Intended for street rods, street machines and show cars these are still high performance dampers.
