High-Performance SFI Approved Aluminum Flexplates
JEGS Billet Aluminum Flexplates start with T-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 153-tooth or 168-tooth replaceable steel ring gear that is pressed and bolted on with six 1/4 in.-20 stainless steel button head cap screws. All flexplates are made to be as light as they can, weighing 5-7 pounds, while strong enough to pass all 29.1 SFI certifications. JEGS flexplates are machined to fit internally balanced small block and GM LS engines, and will work with select torque convertor applications.
