Landrum coil over springs are manufactured in the United States with the highest-quality Chrome Silicon steel wire. Every spring is preset to solid height during manufacturing, allowing them to be compressed to solid while providing consistent high performance throughout their range of travel. Using incredibly precise manufacturing tolerances, they ensure all Landrum springs perform exactly as they were originally engineered.
Each Landrum coilover spring comes with a dyno sheet showing its dependable performance, thus the odd spring rates listed.We list the spring rate on the box/the average spring rate as shown on the dyno slip so you know exactly what you are buying!Many other springs will have a variation of up to 10% and you'll have no idea...that means if you purchase a 200# spring elsewhere you could get anywhere from 180# to 220#!
