The Racing Modular Flexplate was designed specifically for the racer or hardcore enthusiast in mind. The modular design using a laser cut 4130 steel starter ring creates a much stronger design for high horsepower applications. No welds holding dissimilar materials to fail. This laminated design also allows the Flexplate to flex as designed and helps with engine harmonics compared to other billet designs on the market. All Flexplates are neutral balanced. If your engine is externally balanced you can use one of our balance plates to keep it in balance. Flexplates are finished off in a zinc plated finish to protect from corrosion and give it a great look.
