Assault Racing Products Harmonic Balancer W/ ARP Balancer Bolt

Big Block Chevy V8 - Internally Balanced

396 400 402 427

KMJ Performance is proud to sell the Assault Racing BB Chevy Harmonic Balancer! This damper is unique in our line in one respect, it is the only damper not made to the original factory diameter. The original 396/427 dampers were 7" in diameter from G.M. When the 454 came out, G.M. switched to an 8-inch damper. We elected to use the 8-inch diameter on our 396/427 model to maintain consistency and also because we use these dampers in conjunction with a bolt-in counterweight to create the 454/502 model. Although we list this as a 396/427 damper, it will also work on any displacement big block engine that has a neutral balance rotating assembly. These dampers feature 60° of easy to read timing marks plus engraved marks each 90 degrees of the circumference. Comes with ARP 135-2501 balancer bolt.

We are happy to combine shipping on Ebay auctions when possible. Normally it will be the highest shipping amount plus half the shipping amount on other items, sometimes better on orders of small items. Some items are not combined due to size or weight such as crankshafts, torque converters, radiators, cylinder heads, etc. On multiple item purchases the shipping amount is not figured automatically during checkout so please request a new invoice or wait for us to send a combined invoice so we can adjust the total.

We may have auctions that state free shipping when purchased with certain items. If purchasing items with free shipping, please request a new invoice before paying. The shipping amount is not figured automatically during checkout. We are unable to refund your Paypal once payment has been sent. If you have any doubt what your shipping will be please feel free to message us through the ebay message system.
