Upgraded my rear springs last weekend and painted my hood scoop. Went with Dobinson C59-701V Variable Rate Raised Height (75mm Lift) 150-250Kg Constant Load to take the weight from the Wilco, Spare tire, Hi-Lift jack, gas tank, water tank, ladder, and anything else I have back there. It rides WAY better. I noticed heavy bouncing and too much sag with the other Dobinson springs.
