Q & A

  • Speedway Motors and Classic Trucks teamed up to build a 1952 Chevy Truck in celebration of Speedway Motors’ 65th Anniversary. Jason and Tom take a few minutes to talk about the rear suspension the team used on the truck.
  • In this episode, Project Chevelle gets coilovers and a much-needed altitude adjustment. Watch as we install QA1 bolt-on coilover kits front and rear, then dial in the perfect stance and shock settings. Our old Chevelle is really starting to look mean!
