| Important: These rates are good starting places. Each spring combination needs to be rated. A number of factors can influence the rate you see: 1. Location in the spring, ( middle, topbottom), 2. Installed height of the spring. 3. Coil spacing often differs between different manufacturers for the same rate spring. |
