These are top quality "KING" coil springs to fit 2.0" coilover shocks. They can be used in any combination. We recommend (2) 12" springs for a 12" travel shock and (2) 14" springs for a 14" travel shock. These are typically separated by a spring slider (sold separately) and 100lb spring rate difference between top and bottom springs (IE: 250/350).
We sell them in 12" or 14" lengths by 50lb increments from 150 to 450 lbs.
EXAMPLE: 12" long x 2.5" diameter (required for a 2.0" diamters coilover shock) x 150lb spring rate = p/n: 1200.250.0150
Sold EACH.
No returns accepted after the springs have been installed!
