New from Boninfante Friction – the one-piece billet high-performance flexplates. These flexplates are machined from high-strength steel alloy and track tested in the highest level of door slammer drag racing. See more details below.
Official Release:
The “Clutch Kings” of top fuel and funny car drag racing, Boninfante Friction, have taken their manufacturing expertise and applied it to the automatic transmission racing world by developing the absolute best flexplate in existence, with a reasonable price point.
Born out of the need for a bulletproof flexplate in automatic transmission-equipped cars making 5,000 horsepower or more, Boninfante Friction’s one-piece billet flexplates are machined from high-strength steel alloy and track tested in the highest level of door slammer drag racing.
“We picked the best material in the real-world price range and applied the best processing to it. The prototype was raced for two seasons with no cracking, no hole deformation, no surface deformation, and is still running in the car today” said Rob Boninfante, president of Boninfante Friction.
Boninfante Friction uses the same materials and manufacturing processes for all of its products to create a diverse and safe range of applications for maximum effort Pro Mods and Street/Strip hot rods alike. The MEGAFLEX series, starting at $845.00 USD, was custom-designed for full-tilt door slammers and features design elements to withstand extreme horsepower and torque. The SUPERFLEX series, starting at $386.00 USD, is the more affordable, detuned, option for the everyday racer.
