ATI Performance Products is proud to introduce its Super Damper for Chevy V8 LS based engine applications for Z-Body Camaro and Gen 3 & 4 Vortec Trucks. Part #918657 is an OEM sized, 7.48-inch aluminum shell damper for high performance and NON-A/C applications. The main accessory drive is a 6-groove serpentine on the outer shell, in the OEM location, and also features a bolt on, 8mm pitch HTD, 31-tooth drive on the hub in the OEM A/C location. This can be used for any aftermarket accessory of your choice. The damper comes with laser-etched timing marks, a single 3/16 keyway, 4140 Heat Treated hub, and exceeds SFI 18.1 Certification. This damper will fit in the OEM location on:
• LS3 ‘10-‘15 Camaro
• Gen 3 & 4 Vortec Truck 4.8L, 5.3L, 6.0L
• LS1, LS2 ’03-’06 SSR
• LS2 ’06-’09 Trailblazer 5.3L, 6.0L
OEM dampers are optimally tuned to a narrow band of “perceived normal driving conditions” and do not perform well outside of those limits. The ATI Super Damper can handle any engine speeds and driving conditions that get thrown at it to better protect your engine. ATI Super Dampers provide balanced dampening of torsional crankshaft vibrations through all RPM ranges especially during competition use. This damper replaces the OEM GM balancer #12675620 and #19300488 in applications with the OEM main accessory locations where the use of a rear HTD drive is needed. If you need a direct OEM replacement, overdrive, 10% underdrive, or non A/C damper please see these ATI numbers:
