JEGS Billet Aluminum SFI Flexplates

JEGS Billet Aluminum Flexplates start with 6061 aircraft grade aluminum and then surface ground on both sides for precision flatness which ensures minimal radial and lateral run out. Each flexplate is then machined to accept the 168-tooth replaceable steel ring gear that is pressed and bolted on with six 1/4"-20 stainless steel button head cap screws. All flexplates are made to be as light as they can, weighing 5 pounds, while strong enough to pass all 29.1 SFI certifications. JEGS flexplates are machined to fit internally balanced small block and big block Chevys, and will work with all convertor applications.
