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.

Landrum Performance Conical Coil Over Springs taper from a 5.0” OD to a 2.5” ID to prevent bowing that can occur with long and slender coil over springs. Using the proper hardware, the high travel, low-rate conical spring can be used as coil-over springs or conventional mount springs.
Durable and consistent Landrum Performance conical coil springs are designed for circle track, dirt late model, and pavement late model cars.

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.
