LANDRUM PERFORMANCE SPRINGS
Demand The Best

The Industry Leader in Racing Springs Performance, Quality and Craftsmanship

Racing Springs Design Expertise

Since 1966, racers and crew chiefs have been telling Landrum what they want in racing springs, and we’ve been listening. By applying racer focused research and development, our highly trained engineers design spring solutions that give racers what they need for the best racing suspension performance.

What are the Characteristics of Top Performing Racing Springs?

Top performing racing springs are characterized by aspects including:

Use of High-Performance Materials

Materials used for racing springs must not only be durable, but also help to maintain original spring performance. Chrome silicon alloy steel wire meets and exceeds these requirements as exceptional tensile strength makes it highly durable under heavy loads and high-stress environments.

• Withstands high load and unload cycles without permanently deforming
• Can endure millions of load cycles without failing
• Can take shock loads and sudden impacts without breaking or cracking

Close Spring Rate Tolerance

Being sure of the real spring rate is critical. Actual spring rates are most often higher or lower than the spring manufacturer’s stated rate. A spring rate tolerance of ±2% to ±3% of the stated rate is considered the industry standard with racing springs. Tolerances in excess of this can lead to significant error when setting up a car.

No Free Height Loss

Spring free height can be lost due to factors including metal fatigue, or if the spring has been compressed beyond its design capacity. Also known as “spring sag” or “taking a set” this condition can create issues such as:

• Lowering the ride height, affecting the car’s center of gravity and handling and reducing ground clearance
• Alteration of suspension geometry, affecting suspension component angles and camber, caster, and toe settings
• Change of spring rate, making it difficult to maintain optimum tuning for different track conditions or racing strategies
• Compromised corner weighting. Spring free height loss can affect balancing the car’s weight distribution

Landrum Produces Top Performing Racing Springs

• High Tensile Chrome Silicon Alloy Steel Wire and an intensive heat and press process ensure Landrum Performance Springs maintain free height and rate throughout a near infinite operational life
• Landrum Performance Springs hold tolerance to within 2% of specification and it is proven with a dyno sheet provided with every spring. Also, the tested rate is engraved in the spring. No other spring manufacturer does this
• Landrum springs are preset to solid height during manufacture, allowing them to be compressed to solid during use while providing consistent high performance throughout their range of travel
• Our springs are recommended by chassis builders, shock specialists and racers nationwide

Landrum Performance Springs Variety

Landrum Performance Springs offers a wide range of spring types, sizes, and rates for drag racing as well as oval dirt and oval pavement racing. Including dirt modified, dirt late model, asphalt modified, quarter midgets, Legends, Bandoleros, and stock cars.
