7.25" Damper for Big Block Chrysler ( All except early Hemi ) This damper is supplied as a neutral balance damper with two counterweights. This feature, coupled with extra TDC marks, allows one part number to fit all BB Chryslers including 351, 361, 383, 400, 413, 426 and 440 including 426 Hemi (which requires 81013 pulley spacer). Will not fit 331, 354, 392 early Hemi. Complete fitment instructions come with the damper. A tube of thread sealant is included.
PowerForce+Plus Race Dampers are made from bulletproof 1045 steel. These dampers are designed to be installed on race engines that may rev over 10,000 rpm. Optimum damping occurs in the 6500 to 7500 rpm range. The machine work on these dampers is second to none and the critical fit tolerances and balance are held more closely than OEM. All externally balanced dampers feature bolt-in counterweights. This feature allows for swapping weights between dampers (Ford) or adding them to internal balanced dampers (Chevy) if you change applications. The basic damper in any family is the same with either a different counterweight (Ford) or an added counterweight (Chevy). This provides an unlimited amount of flexibility. Plus, you can't buy a more accurately balanced damper.
What is Bonding? When dampers are bonded, what does this mean? It means that the elastomer (rubber) that is sandwiched between the ring and the hub is bonded, or vulcanized, to metal. This is similar to the process used to bond the metal motor mounts to the rubber vibration isolaters used in these mounts. This greatly increases the safety of the damper as most stock, and many inexpensive aftermarket dampers, are just pressed together and under heavy duty applications, the ring can rotate, moving your TDC mark from the true position, or fly off the engine. And that is very bad!
