In order to shed some more light on the myriad of available spring options, we’ve created a simple comparison of each. IND has each type of spring in stock and measured the overall length, coil count, and coil diameter of each spring. We also tested the spring rate of each on Fall Line’s spring rate tester, to see what the actual measured rate is.
A few notes:
- The springs shown here may have a variance in material. It is not possible for us to know the metallurgical makeup of the springs, and this will obviously have an impact on spring rate, ride quality, and other factors.
- It is my hope that this thread will improve in depth and scope in the future, as IND gathers more information and data.
- In the near future I will also measure compressed length of all of the springs, to give a clearer picture of how each spring functions.
- Calculating spring rate based on OD/ID of the springs is not necessarily possible, because nearly every spring set has a complex shape, with the exception of the KW rear springs.
