the front springs on my K20 are worn badly. so badly, that its a pain to drive with the blade off, as they're constantly bottoming out on the bumpstops. i was thinking about replacing them. it would be cheaper to buy a set of small lift springs for it. i'm thinking about a 2.5" lift, and when the tires need replaced step up to a set of 33s. what springs would you recomend for a truck that carries a plow?
