Choosing the correct spring for the correct application is the key to achieving maximum performance. Stock springs are not built with racing in mind and will not help your Hellcat Challenger/Charger compete on the street and track. Blending durability and performance, BMR has designed the SPD110 Demon Killer Drag Springs for the drag race crowd who want to the ultimate in straight-line performance.
All BMR springs are manufactured from chrome silicon high-tensile spring wire, and are cold wound on a CNC coiling machine. The CNC coiling head can adjust the spring diameter in real time to ensure that every spring is exactly the same. This guarantees that your right spring matches your left spring. Every BMR spring is compressed solid at the factory, not once, but twice. This gives the spring its permanent set, and guarantees no sag. BMR springs are stress-relieved at 750 degrees F, ensuring most stresses induced during the winding process are eliminated. All springs are then shot-peened to eliminate residual surface stresses. Many spring manufacturers skip this step, but BMR insists on this operation as part of our spring manufacturing process. Every spring is computer tested as the last step—every spring, not just a sample from each batch. Each spring is loaded in the spring tester at the factory, then compressed and the CNC load cell measures the force for a variety of spring lengths. This allows BMR to offer a LIFETIME WARRANTY against spring sag.
These springs will maintain your Hellcat’s factory height, and feature a fine-tuned spring rate (212 lb/in front, 570 lb/in rear) to give you great straight-line performance. The linear spring rate offers plenty of support, while remaining soft enough for great weight transfer. When performance is a must, rely on BMR Suspension!
