Overview

ATI’s patented Super Damper is the only harmonic balancer developed exclusively for high-RPM performance engines (6000+ RPM). Its proven elastomer design is 2-in-1: a 4″ diameter damper and a 7″ diameter damper in two shells that bolt to the crank hub. Inner and outer shells are aluminum or steel to contain the steel inertia weight. The inertia weight has eight computer-machined grooves to retain the proper durometer O-rings (installed at ATI and dyno tested for each application). O-ring life has been tested in Winston Cup competition over two million cycles and in drag racing engines for 10 years (exceeds SFI 18.1 specs). Units can be rebuilt by installing new O-rings. Shells have a black zinc chromate finish with computer-controlled, laser-engraved 360° timing marks.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
