Tight Helix Coil Springs – Elite Series
What Are Tight Helix Coil Springs?
Landrum Tight Helix Coil Springs feature more coils and tighter coil spacing. This allows for a higher spring load rate with less travel. They also achieve coil bind faster than conventional springs.
Tight Helix springs feature closely wound coils for a higher number of coils per unit length than a spring with a wider pitch. This allows for a more compact design compared to wider pitch springs.
Many racers and dealers asked Landrum to make these springs, and we delivered. Multiple test sessions were performed to ensure the perfect tight helix rear coil spring.
What Are the Benefits of Tight Helix Coil Springs?
- Reduced spring bowing which avoids shock damage that can be caused by spring contact.
- Improved handling, braking and acceleration.
- Short spring length/high load spring rate provides for a higher spring rate in a confined area.
How do Tight Helix Springs Improve Handling, Braking and Acceleration?
The increased spring rate of tight helix racing springs helps to minimize body roll when the vehicle is subjected to lateral forces during cornering. This leads to more stable and predictable handling.
Tight helix racing springs can help improve the stability of the vehicle by reducing pitch and dive under braking and acceleration. This ensures that the tires maintain better contact with the track surface.
The Best Tight Helix Coil Spring Design
Landrum high performance engineering and materials provides racers with the best Tight Helix Coil Springs.
- Designed using the latest spring design software and state-of-the-art engineering technology.
- Produced with US made High Tensile Chrome Silicon Alloy Steel for superior strength, reliability, and the ability to retain their original high-performance characteristics after repeated use.
Landrum Tight Helix Coil Springs are tested to consistently be within 2% of specification. This ensures racers get the spring rate they are expecting. We prove it with a dyno sheet provided with each spring showing the performance of the spring as it is compressed. No other racing spring manufacturer does this.

Designed for Use with our 18″ Front Drag Racing Coil Springs.
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.

Landrum Progressive Coil Springs for circle track cars give you rugged and dependable performance that’s trusted by racers nationwide.
How Do Landrum Progressive Coil Springs Improve Handling and Performance?
Landrum Progressive Coil Springs deliver rugged, dependable performance trusted by racers nationwide. These springs offer superior handling with varying stiffness throughout the suspension travel. They start soft, providing better grip and smoother handling on rough tracks. As the spring compresses, it becomes stiffer, preventing bottoming out and improving stability under high load. This balance enhances cornering ability, reduces chassis roll, and adapts to different racing conditions.
We worked closely with racers to develop Landrum Progressive Coil Springs, ensuring they deliver the performance, durability, and long-term consistency you need.
What is the Difference Between Progressive Coil Springs and Constant Rate Coil Springs?
While constant rate coil springs are wound to have equal spacing between the coils, coil spacing of progressive springs varies with narrow spacing at one end of the spring, and wider spacing at the other.
- Constant rate coil springs compress at a linear rate, meaning rate of force needed to compress the spring a certain amount remains the same. For example, a spring with a 300 pound-per-inch linear rate (also known as the rate of deflection) will compress one inch when 300 lbs. of compression force are applied. The spring will compress another inch if an additional 300 lbs. of force is added, and so on.
- With Progressive rate coil springs, the rate of deflection increases as the as the spring is compressed. The spring has a softer rate at the beginning of its range of travel. So, it can easily cushion small compression forces and shock loads. As compression forces increase the spring progresses to a higher rate to handle larger compression forces.
What is the Benefit of Progressive Springs?
When it comes to circle track racing, the initial lower spring rate allows the suspension to smoothly transfer weight as the car enters a corner, and the higher spring rate comes into play as the spring compression load increases.
What Metal are Landrum Springs Made With?
Landrum produces coil springs with the highest quality US made High Tensile Chrome Silicon Alloy Steel. This results in springs with superior strength, reliability, and the ability to retain their original high-performance qualities after repeated use.
