Landrum 13in. x 5in. x 100# Rear Spring J100

If you're building a dedicated track car or street/strip machine, suspension geometry demands precision—and that starts with a properly-rated rear spring. The Landrum J100 delivers a firm 100 lb/in rate in a compact 13-inch package, giving you predictable load transfer and consistent chassis balance through corners and under acceleration. This Gold Series coil spring is engineered for repeatability, making it the choice for racers who need their suspension to respond the same way, lap after lap.

Whether you're tuning a drag setup, road racing platform, or weekend warrior build, this spring provides the stiffness needed to control squat and maintain ride height without sacrificing reliability. The gold powder coat resists corrosion, ensuring longevity even in harsh environments.
