Hi-Riders (1978)

aka: The Hi-Riders

Mark and Lynn (Darby Hinton and Diana Peterson) are drawn into acts of hatred and revenge after trying to collect on a bet with a “Hi-Rider,” a drag-racing car club known for “jacking up” the rears of their cars much higher than stock. When a local “hothead” (Roger Hampton) challenges the club to a race, both drivers are killed in a spectacular explosion. The local boy’s father (Stephen McNally) vows revenge, and an action-filled chase through town ensues between the Hi-Riders and the local henchman. Also with Neville Brand.
