This new design is a direct replacement for the stock OEM damper. The heart of this unit is the tried and true "damper within a damper" design that has put ATI ahead of the rest. The outer shell is machined to utilize the factory serpentine 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. The factory lower timing cover will need to be trimmed for hub clearance.
