ATI has designed a 6.325" damper for the 1G/2G DSM, 4G63 and 4G64 for high horsepower street & race use. This new design is a direct replacement for the stock OEM damper. The outer shell is machined to utilize the factory belt set-up and mounts to the factory crank via a custom hub which replaces the stock timing gear. The damper's outer diameter is 12% larger than OEM.
Install Notes:
The factory lower timing cover will need to be trimmed for hub clearance.
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
