Landrum Springs' manufacturing process ensures consistent wire diameter, coil pitch, and preload, which are critical for ride comfort and long-term durability.

This coil spring is particularly beneficial for mechanics and enthusiasts who are actively tuning suspension geometry, including ride height and anti-squat angle. Its 20-inch length provides adequate clearance in tight chassis designs while maintaining proper suspension travel. With its robust design, this spring is an excellent choice for those looking to enhance their vehicle's performance and handling characteristics.
