ATI Performance Products, Inc. is proud to introduce its all new Super Damper (Part # 917278) designed for the 1997-2013 Corvette LS1, LS2, LS6 and LS3 without dry sump engines for both street and high performance racing applications. The new aluminum shell underdrive damper is a direct fit replacement for the stock OEM unit and is capable of handling a wider variety of driving habits specific to individual Corvette owners. Plus, this damper will eliminate the damper wobble common with the factory GM dampers. The aluminum design eliminates weight while the underdrive is designed to improve engine performance by underdriving the ancillary engine accessories including your alternator, ac compressor and power steering pump.

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.

The patented ATI Super Damper is the only crankshaft damper designed exclusively for high performance Chevy engines. Check out these features:

  • Eliminates torsional crankshaft vibrations
  • Exceeds SFI 18.1 specs
  • Black zinc chromate finished
  • Tunable, rebuildable, and extremely efficient at ALL RPM
  • Laser engraved 360 timing marks
  • 6.78" Diameter
  • 4.50 lbs total weight
  • 6 -rib serpentine pulley design w/10% underdrive

ATI Performance Products, Inc. specializes in producing and maintaining high performance harmonic balancers for street and strip applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail, and rigorous testing under race conditions.

Note: Always replace the damper bolt with a brand new bolt when replacing the harmonic damper. The LS series damper bolts are known as TTY bolts and they are made to only be torqued one time. Use TKO part #   2133      harmonic balancer bolt for LS1, LS2, LS3 w/o drysump and LS6 Corvettes. Requires new Goodyear main serpentine belt and A/C belt to complete installation. This balancer will not fit the LS3 engine with dry sump oil system.
