Landrum Performance Spring has added bump stop spring technology to their inventory. Many of you have used bump rubbers or a die spring. This is a coil spring made specifically for the bump stop applications. This spring is made of high tensile strength material as are our other VB series springs. This offers fast, easy set-up, and consistent spring rate. We offer 5 rates: 600, 800, 1000, 1200, and 1400. We will also be carrying the bump cups to help seat the spring. We will offer two cups sizes. One will accommodate 5/8 and the other 14mm shock shafts. The cups are made of high grade aluminum with an anodized clear finish.
