What ProTorque does
ProTorque, founded in 1983, is a Philadelphia-based manufacturer of high-performance custom torque converters for drag racing and street/strip performance vehicles, operating as a division of Boninfante Friction (Boninfante Group). The company designs and builds its converters using CAD/CAM engineering and CNC machining, with proprietary features that include 7075 T6 billet aluminum bolt-together drive covers, custom billet stators machined from solid billet steel or aluminum, Safe-D indexed fastener technology using aerospace-grade 4340 studs, furnace-brazed turbine assemblies, silicon bronze TIG welding on blades, and Torrington-style bearings replacing phenolic washers. The product portfolio spans street/strip converters (Street Muscle from $387, Pro Drive from $587, LSXT from $1,387), competition-grade series (Bullet Race from $1,187, UX Series from $1,887, EV Series from $2,422 rated up to 5,500 HP), a Pro Diesel line ($987-$1,487, up to 1,500 HP), and Boninfante flexplates (MEGAFLEX, SUPERFLEX, STREETFLEX from $149-$925). Supporting offerings include branded apparel and gear, service requests (freshen-ups from $197), and a Torque Converter Recommendation Engine on the e-commerce website for guided product selection.
The company generates revenue primarily through one-time hardware sales of torque converters and flexplates priced by series and horsepower rating, complemented by service and repair work, custom-engineering quotes based on detailed vehicle specifications, and a three-tier affiliate program (5%/10%/20% commission) that drives referral sales. Go-to-market combines a 237+ authorized dealer network spanning all 50 US states plus international distribution in 10+ countries (Australia, New Zealand, Canada, UK, Dubai, Finland, Saudi Arabia, Kuwait, Pakistan, Netherlands), direct e-commerce through protorque.com, custom-built direct sales, and the #TeamProTorque sponsorship program that uses sponsored racers as brand ambassadors. Customer segments include professional drag racers (NHRA Factory Stock Showdown, Street Outlaws participants), street/strip enthusiasts, diesel performance owners, and performance shops/tuners. Brand exposure is amplified by Discovery Channel's "Street Outlaws" (estimated 3.5 million viewers in its 10th season), where multiple sponsored racers run ProTorque-equipped vehicles.
ProTorque operates with 1-10 employees from its production facility at 555 Industrial Park Drive in Philadelphia, Pennsylvania (relocated there in early 2020 following the Boninfante Friction partnership), with a mailing address in Whiteville, Tennessee, and a Yeadon, PA RMA/warranty returns address. The company is privately held, has no disclosed funding rounds or institutional investors, and is led by founder Joe Rivera, President Joe Rivera Jr. (former TCRA President), and Director of Motorsports and Sales Tom Kundrik (hired April 2021). Recent strategic activity has centered on expanding the product line (X8 Series in 2021, X10 Series in 2022), digital tooling (TCRE in December 2022), and broader distribution into modern OEM transmission platforms and diesel applications.
