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.
Tight Helix Coil Spring Sizes
Landrum Tight Helix Coil Springs are designed for rear suspension applications and are currently available in the following sizes.
- 5.0” OD
- Free Length: 11”
- Rates: 175, 200, and 225 lbs. per inch

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 Performance Front Drag Racing Coil Springs are designed to deliver the performance, reliability, and consistency you need to win. Landrum front drag race springs are taller than OEM springs and use softer rates to give your car the correct ride height while providing more stored energy for instant weight transfer during launch. This helps to give you increased torque control, reduced wheel hop, and faster 60ft and 1/4-mile ET’s.
Landrum drag race springs are available for the front suspension of GM vehicles and are offered in configurations to fit OEM A-Arms and Aftermarket A-Arms with no modifications required. Springs with a 5” outer diameter and 18” length are available for 1964-1972 GM vehicles, and springs with a 5.5” outer diameter and 18” length are offered for 1973 and newer models.
Front Drag Racing Coil Spring Rates
Our Front Drag Racing Coil Springs are available in a range of rates including:
- 150 lbs./in.
- 165 lbs./in.
- 180 lbs./in.
- 200 lbs./in.
- 225 lbs./in.
- 250 lbs./in.
Technical Information
All front springs are closed and ground on one end to provide proper contact with the frame. The opposite end is either open to properly fit into the lower control arm of OEM A-Arms or closed for Aftermarket A-Arms.
Landrum Performance Front Drag Racing Coil Springs are light weight, high travel and made with the highest-grade High Tinsel Chrome Silicon Steel wire.
The drag race springs are cold wound, not hot wound. Each is properly heat treated and stress relieved to ensure the sides of the spring remain parallel during installation.
All Landrum Front Drag Racing Coil Springs use standardized testing procedures to ensure the best quality and performance.
Our springs are powder coated and not plated which avoids hydrogen embrittlement, a condition that can be caused by electroplating and can weaken metal.
Each spring is manufactured with the highest tolerance in mind and is designed with the correct pitch and height ratio to insure a consistent rate throughout the entire cycle.
