Take the guess work out of selecting the right shocks for ever-changing track conditions. Speedway Motors shock department has worked with several teams to develop these winning B-Mod shock combinations. They have run thousands of laps testing and have won many features. These shocks are based on the SZ Series shocks, which makes them a great choice for IMCA and WISSOTA Modifieds/Sport Mods. Speedway has tested and hand-selected the combination of valving and pistons to promote ideal handling and improved feel for any track condition. Each shock is built and dyed in-house. Each shock is individually labeled for each corner of the car with a 'Mud', 'Mid' or 'Slick' notation, making it easy to hit the right setup every time. B-Mod Right Front 'Slick' shock, 7" stroke.
