For over 35 years Speedway Engineering has been dedicated to manufacturing precision-built rear ends and chassis components for race cars. 

Founder Frank Deiny’s dedication to providing racers the best racing equipment quickly became the mission statement of the business, and under his leadership Speedway Engineering became a primary source for racers in the top divisions of NASCAR, ARCA, and many other top stock car racing categories.  Performance, reliability and first-class service became the key characteristics of Speedway’s growing product line. 

Throughout the ‘90’s and today, Speedway Engineering has grown under the helm of Ken Sapper, expanding the product line to include an entire list of suspension and drivetrain products: Ford 9” Rear End Housings, Quick Change Differentials, Axles, Sway Bars, Hubs, and a comprehensive line of suspension components.  Ken’s experience as a racer and long-standing knowledge of Speedway Engineering (one of the first employees) has enabled Speedway Engineering to continue its position as an industry leader.

Speedway’s success has been a result of its dedication to understanding the racer’s needs and filling those requirements.  All Speedway Engineering products represent the best in performance and reliability, manufactured to the highest quality standards and serviced by a staff that has the experience and knowledge to make a difference. 

At Speedway Engineering, we’re dedicated to performance.  We look forward to the opportunity to help you reach the winner’s circle.
