Landrum Performance Stock Appearing Double Pig Tail Rear Springs are offered in 7” OD x 14” length. They’re made to resemble black painted stock double pig tail springs and are offered in a broad range of rates. Making it easy to find the rate you need for the best handling, traction, and overall performance.
Stock Appearing Double Pig Tail Rear Springs are developed for circle track and drag racing classes that require stock appearing springs and don’t require use of spacers or weight jacks.
Landrum Performance Springs are for racers who demand the best spring performance, accuracy, durability, and consistency.

Landrum Progressive Coil Springs for circle track cars give you rugged and dependable performance that’s trusted by racers nationwide.
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.
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.
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.
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.
