    Tall and narrow black colored spring with narrow wire diameter that is an example of Landrum Performance Front Drag Racing Coil Springs.

    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.

    Spring Compressor for Long Length 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.

    Gold Series Coil Springs Front and Rear
    • All front springs are closed and ground on one end to provide proper contact with the jack plate, not forged. The opposite end is either open or closed tangential to fit properly into the lower control arm.
    • All rear springs are closed and ground on both ends which insures proper contact with the jack plate and spring seat.
    • Made of the highest grade of Chrome Silicon wire found worldwide.
    • Cold wound, not hot wound. Each coil-over spring is properly heat treated and stress relieved to insure the sides of spring remain parallel during installation.
    • Standardized testing procedures.
    • Powder-coated, not plated to protect the spring from hydrogen embrittlement, a corrosive break down of the spring’s surface which decreases the spring’s life.
    • Each spring is designed with the correct pitch and height ratio to insure consistent rate throughout the entire cycle.
    • Every Landrum Coil spring comes with a dyno sheet. The dyno sheet shows the dynamic rate and force output for the spring in 0.200” increments. This allows the customer to know exactly what the spring rate is and means when you change a spring, you know exactly what change is being made.
    • Custom winding is available upon request.
    • The material and workmanship in these springs are second to none and proudly Made in the USA.

    Black Progressive Coil Springs standing on end

    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.

    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.
