Coil Spring, 5.0 OD X 7IN PULL BAR Landrum Pull Bar Springs manage torque transfer, control wheel hop, and maintain traction during acceleration by modulating the forces transmitted to the rear axle. Pull bar springs are used as part of a pull bar assembly. A pull bar is connected between the rear axle and the chassis to help control torque application. As engine power is transferred to the rear wheels, the rear axle tends to rotate rearward due to the torque. The pull bar controls the rate of rotation and ensures that power is delivered to the rear wheels in a more controlled and efficient manner. Thereby helping to control traction. Designed using the latest spring design software and state-of-the-art engineering technology. Only the best grade of high tensile chrome silicon alloy steel is used for strength, durability, and lightness. Use of high-quality steel and an intensive heat and press process ensure pull bar springs maintain free length and rate throughout a near Infinite operational life. Landrum Pull Bar Springs are tested to be within 2% of specification. We prove it with a dyno sheet provided with each spring that shows the performance of the spring as it is compressed. No other racing spring manufacturer does this. With a range of single and progressive rate springs available, race teams can find just the right springs to fine-tune their car’s handling. High-quality steel. 5” OD. 7” Length. Made at our Indiana, USA facility.
