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.

Landrum Progressive Coil Springs for circle track cars give you rugged and dependable performance that’s trusted by racers nationwide.
Progressive Coil Springs for Circle Track Cars
In the 1960’s, Landrum Springs owner Robert Landrum, who was also a dirt oval racer, used his racing experience to engineer high performance racing springs that quickly became popular with local racers. As oval track racers nationwide discovered the performance advantage of Landrum Springs, the company became the go-to source for high performance racing springs.
Today, we continue to work closely with racers to deliver the best performing progressive rate coil springs. We ensure Landrum Performance Springs Progressive Coil Springs deliver the performance, durability and long-term consistency racers need to take the best set, every time.
What’s 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’s the Benefit of Progressive Springs?
When it comes to circle track racing, the initial lower spring rate allows the suspension to smoothly take a set as the car enters a corner, and the higher spring rate comes into play as spring compression load increases when weight transfers as the car progresses through the corner.
