Landrum Dirt Late Model Coil Over Springs give you the winning edge.
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.
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.
Landrum offers other springs for dirt late model cars:
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.

Achieving peak performance in quarter midget racing requires precise suspension tuning. Racers depend on setups tailored to track conditions including track size, banking angles, and surface grip. They rely on lightweight, durable springs that maintain consistent performance and are available in a wide range of spring rates. Landrum Quarter Midget Springs are designed to deliver exactly that—optimal performance, durability, and reliability for every race.
Landrum Quarter Midget Springs are crafted from US-made High Tensile Chrome Silicon Wire, known for its high strength-to-weight ratio. The wire’s unique alloy mix makes for springs that are lightweight yet exceptionally strong, ensuring superior performance without adding unnecessary mass.
Quarter midgets depend on finely tuned suspension setups due to their lightweight and sensitivity to track conditions. Choosing the right spring rate for track surface, driver weight, and handling characteristics is essential for optimal performance. To achieve consistent and predictable handling across varying racing conditions, racers need a wide and precise range of spring rate increments.
Landrum Quarter Midget Springs meet this need by offering 4”, 4.5″ and 5” lengths, with rates from 75 lbs./in to 125 lbs./in in 5 lb. increments and with no tolerance overlap. Providing spring rate options for consistent suspension tuning across a variety of conditions.
Please note, Landrum Quarter Midget Springs in 4“ and 5” lengths are Gun Metal Grey in color and 4.5” length are Flat Black in color.
For 1/4 midget racing, accurate spring rates without tolerance overlap are essential, making it crucial to know the exact spring rate. Each Landrum Quarter Midget Spring is rigorously tested to ensure it meets its rate specification within a ±2% tolerance and maintains that performance throughout its range of travel. A dyno sheet is included with every spring, documenting its test results to guarantee you receive the exact performance you’re expecting.
Racers look for consistency and repeatability; ¼ midget springs that can take repeated compression and rebound cycles without losing performance or free height. Landrum manufactures springs to meet these high-performance standards. Landrum Quarter Midget Springs are cold wound, not hot wound, and undergo precise heat treatment and stress relief for high durability. Preset to solid height during production, these springs can be fully compressed repeatedly without losing performance or free height, ensuring consistent performance throughout their range of travel. This design allows them to reach coil bind without taking a set, providing long-lasting, reliable performance even under extreme conditions.
Since 1966, Landrum Performance Springs has been providing racers with race winning high performance springs for racing. Using only the best US sourced High Tensile Chrome Silicon Spring Wire, Landrum springs are expertly produced at our Indiana location.
Look for springs that offer consistency, durability, and precise rate control. Because quarter midgets are lightweight and highly sensitive to setup changes, even small spring differences can impact performance.
Extremely important. The right spring rate affects handling balance, corner entry and exit, and tire grip. Racers often adjust spring rates to suit different track conditions, driver weight, and driving style.
Racers rely on springs that maintain consistent performance through repeated compression and rebound cycles. Consistency ensures predictable handling and repeatability, critical for achieving optimal race results.
Landrum Quarter Midget Springs are preset to solid height during production, which allows them to be fully compressed without losing free height, ensuring consistent performance throughout their full range of travel.
Landrum Quarter Midget Springs are crafted from US-made High Tensile Chrome Silicon Wire, which is known for its excellent strength-to-weight ratio.
Landrum offers Quarter Midget Springs in two height options: 4” and 5”.
Each Landrum quarter midget spring is rigorously tested to meet its specified rate within a ±2% tolerance. This ensures that the spring performs exactly as expected throughout its range of travel.
Whether it’s maintaining consistent rates throughout the full range of travel or ensuring quick recovery over bumps, Landrum Quarter Midget Springs are designed to deliver consistency, durability and performance lap after lap.

Landrum Progressive Coil Over Springs provide the reliable and consistent high performance you need to win.
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.
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.
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.
Since 1966, Landrum Performance Springs have helped put racers in victory lane. Racers and crew chiefs trust Landrum for the best spring performance.
