What Makes Gold Series Racing Coil Springs Different?
High-Tensile Chrome-Silicon Steel
Gold Series racing coil springs are manufactured from USA-made high-tensile chrome-silicon alloy steel selected for strength, durability and consistent spring performance through repeated compression and extension cycles.
Spring Engineering and Design
Landrum uses advanced spring-design software and proven engineering principles to develop Gold Series linear-rate springs that provide consistent, predictable performance throughout the spring’s working range. We also work closely with racers and chassis builders to design and produce springs that meet the specific requirements of their racing applications.
Individually Rate Tested
Every Gold Series racing coil spring is individually tested to verify its spring rate and is supplied with a dyno sheet documenting spring performance through compression.
How Are Gold Series Racing Coil Springs Tested?
Each Gold Series racing coil spring is compressed through its working range and tested to verify that its actual spring rate is within ±2% of the specified rate. Testing measures the relationship between load and spring travel to confirm the spring performs at its intended linear rate.

This Spring Compressor makes it easy to install our 18” Front Drag Racing Coil Springs. Standard spring compressors just aren’t long enough to properly compress 18” springs, but our spring compressor is. The spring compressor is inserted through the top shock absorber opening and a long length threaded rod allows the compressor fingers to reach down to the bottom of the spring. A position adjustable bearing located toward the top of the rod seats on the top of the shock opening so the threaded rod turns freely when the spring compressor is tensioned or loosened.
