ATI Super Damper Crank Pulley / Balancer - VQ35DE

Brand: ATI



Fits models: 350Z / G35 / FX35 / FX45

Price:$389.00

The patented ATI Super Damper for the 2003-2006 Nissan 350z / Infiniti G35 is the only damper designed exclusively for high performance engines. Designed to have an OEM fitment on all models equipped with the VQ35DE platform. Will not fit cars equipped with a VQ35HR.

This is recommended for any high HP motor. Each time the air/fuel mixture inside a cylinder is ignited, the combustion that occurs creates a torque spike that is applied to the crankshaft through the piston and connecting rod. This torque spike is so severe that it not only turns the crankshaft, it actually twists the crankshaft ahead of its normal rotation and then the crankshaft rebounds. This twisting action is known as torsional vibration. When these torque spikes and forces get into phase with the natural frequency, critical torsional harmonic vibrations occur and can be seriously destructive to the bearings and the crankshaft. Dampers are designed to control those destructive vibrations.

Features:ATI Damper

  • 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
  • Race version is NOT designed to work with original belts or accessories. Custom applications ONLY.

Specifications

  • 6.780'' Outside Diameter
  • Aluminum outer shell and pulleys
  • Integral hub and inner shell (not removable)
  • Provisions for factory accessories including AC, Alternator and Power Steering
  • Built in the USA

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.
