Landrum Dirt Late Model Coil Over Springs give you the winning edge.
What are Dirt Late Model Coil Over Springs?
Landrum Dirt Late Model Coil Over Springs are engineered for maximum travel, clearance, coil spacing and lightness to meet and exceed the extreme demands of Dirt Late Model racing. Our springs provide the performance, durability and consistency needed to win.
Coil over springs that don’t take a set
- Preset to solid height during manufacture, allowing them to be compressed to solid during use while providing consistent performance throughout their range of travel.
- Dirt Late Model Coil Over Springs are built to operate at maximum stress levels without losing free height. So, they’re able to go to coil bind and not take a set.
Proven dirt late model coil over springs performance
Landrum springs have the closest tolerances in the industry and are tested to be within 2% of specification. 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.
Top quality materials and engineering
- Manufactured with only the best grade of high tensile chrome silicon alloy steel for strength, durability, and lightness.
- Designed using the latest spring design software and state-of-the-art engineering technology.
Intensive quality control processes
- Tensile and compressive stiffness of the wire is checked before the coiling process.
- Springs undergo an intensive heat and press process.
- Each spring is individually tested for quality and consistent performance.
Dirt late model coil over spring sizes
- Dirt Late Model Coil Over Springs have 2.5” ID and are available in many different length and rate combinations.

Landrum Progressive Coil Over Springs provide the reliable and consistent high performance you need to win.
What Are Progressive Coil Over Springs?
Progressive springs provide a varying spring rate throughout their range of travel. The initial spring rate is low but progressively increases as the spring is compressed. The springs are commonly used in circle track racing applications to help control body roll when cornering.
How Do Progressive Rate Coil Over Springs Work?
Progressive rate coil over springs are produced with varying coil spacing. At one end of the spring the coils are narrow spaced and as the coils progress to the other end of the spring the spacing becomes wider.
When the spring is minimally compressed all coils of the spring are active and a lower spring rate is in effect. As the spring is further compressed, such as when a car takes a set as it enters a corner, the narrow-spaced coils collapse on top of each other until they touch, which is also known as “going solid”. When this happens the number of active coils of the spring is reduced, which results in a higher spring rate.
What Type of Steel is Used for Progressive Coil Over Springs?
We manufacture our progressive coil over springs using the highest quality US made High Tensile Chrome Silicon Alloy Steel for strength, reliability, and to maintain their original high-performance characteristics after repeated use.

Landrum Coil Over Barrel Springs avoid the bending and bowing issues associated with long length coil over springs.
High travel coil over springs with lengths more than 4 times their width have a tendency to bow when compressed. The greater the length of the spring, the more it can bow. Causing spring rate inconsistency, and possibly cause damage to shocks if they make contact. Our Coil Over Barrel Springs use a barrel shape design to prevent bowing when they’re compressed. Thereby maintaining spring performance.
How Do Coil Over Barrel Springs Prevent Bowing?
- The conical shape of our Coil Over Barrel Springs allows more even stress distribution across the length of the spring, which provides lateral stability. Making the springs less prone to bending or bowing sideways during compression.
What Are the Advantages of Coil Over Barrel Springs?
- Provide more consistent and controlled weight transfer during cornering and acceleration. Keeping tires in the best contact with the surface.
- Increased spring travel before coil bind.
- Lateral stability keeps the spring properly seated.
- Avoiding bending or bowing keeps the spring from rubbing against the shock body, which could damage the threads of the shock adjusting perch.
- The barrel shape allows for efficient use of materials.
- By tapering the spring, it can be designed to be both lightweight and structurally sound.
The Best Materials and Engineering
- Manufactured with only the best grade of high tensile chrome silicon alloy steel for strength, durability, and lightness.
- Designed using the latest spring design software and state-of-the-art engineering technology.
Intensive Quality Control Processes
- Tensile and compressive stiffness of the wire is checked before the coiling process.
- Springs undergo an intensive heat and press process.
- Each spring is individually tested for quality and consistent performance.
Dyno Sheet
- Every Landrum Performance Coil spring comes with a dyno sheet that shows the dynamic rate and force output of the spring in 0.200” increments. This allows you to know exactly what the spring rate is and means when you change a spring, you know exactly what change is being made. No other manufacturer does this.
