Hey there fellas so I just built myself up a new ride I got a psylo xc fork from my shop and I need to stiffen it up, i know that i would need the black spring for it but unfortunatley being an older model fork the spring kits are super hard to find. Although someone told me I could just figure out the dimensions of the spring and grab another spring that will fit my fork, what i want to know is, is this possible? if so what spring should i use? also on the side of the fork on the the label is says spring: u-turn... does that mean that any "U-Turn" spring will fit?
