A closed end spring is designed to resist stretching and twisting. To “close” the ends, the space between the last two coils is reduced so they touch. In some applications, such as with Landrum springs, the closed ends are then flattened to ensure a stable contact surface. How are spring ends flattened? Flat end springs […]

Knowing the actual rate of each spring is crucial. Whenever a manufacturer sets up to run several hundred springs of one particular rate, the end result is less than perfect. Even though the winding process using CNC automated equipment is consistent, the variances in the quality of spring wire is not as consistent. As a […]
Using stacked springs allows a car to run on a very soft spring rate on entry of the turn, and progress to a heavier rate as it is needed through the middle and exit off the turn. The stacked spring concept is being used on the left rear, right front and sometimes on the right […]
A compression spring is defined as a mechanical device that produces a force when deflected and returns to its original height, ready to deliver the next repeat stroke and associated force. To accomplish this feat, the spring must produce a spring rate, a given amount of force per each inch of travel. That said, a […]
One of the most interesting phenomena of any product, promoted and sold, is the illusion of superior product exhortations. My stuff is better than your stuff. This, of course, is a core function of the sales world – to display an item, device or tool that creates a better world. This is grandly exploited in […]
We are excited to announce our new Dealer Portal on the Landrum website. This will allow Landrum Dealers and WD’s, to login, check availability and cost, as well as turn in a PO. The portal will also store the history of PO’s placed through the portal. This is a 24-hour 7 day a week opportunity […]
Long Coil Springs Can be a Challenge to Compress We know installing long coil springs can be a challenge as standard spring compressors just aren’t long enough for their proper compression. So, we have introduced a spring compressor for long coil springs, specifically designed for use with our 18” Front Drag Racing Coil Springs. The […]
