SBC 168 Tooth Flexplate SFI - Int. Balance

Manufactured in the USA on state-of-the-art CNC equipment, ATI's Flexplates are created from SFI-spec steel and are SFI 29.1 Certified and are double MIG/TIG welded for additional strength and lasting precision pass after pass. Each ATI flexplate is manufactured and toleranced from OEM drawings to ensure a precise fit and location. Each plate is quality inspected to exceed the flatness and run-out tolerances of the OEM units and is precision balanced on Hines digital equipment with a resolution of 1/10 oz-in. Superplates are manufactured from a material with a 90,000 lb. tensile and 80,000 lb. yield strength to withstand thousands of cycles. Superplates are laser machined to avoid heat and stress that stamping inflicts on the part. The crank bolt holes and center hole are bored to exacting tolerances using ATI’s in-house CNC machines. The Superplate uses the correct “grip length” crank bolts as dowels to prevent the plate from moving under high torque conditions. ATI Superplates are neutral balanced for use in internally balanced engines and exceed SFI 29.1 & 29.2 ratings. This flexplate is designed for Chevrolet Small Block engines with a 2-piece rear seal crank flange, typically found in models from 1985 and older.
