ATI SFI Flexplates

4.59 out of 5 stars 73 Customer Reviews

Made on state-of-the-art CNC equipment, ATI SFI flexplates are double MIG/TIG-welded with certified American-made materials that far exceed SFI specs for safety. They're manufactured and toleranced from actual OEM drawings to ensure precise fit and location. Each is quality-inspected to exceed the flatness and runout tolerances of the OEM units. They are also precision-balanced on Hines digital equipment with a resolution of 1/10 oz. per inch. Available in dozens of configurations, ATI SFI flexplates can be ordered for fitment on vehicles covering every decade since the mid-1950s.
