Second trip to dunes and can't figure out why front end bucks like a bronco. I put on new ZBroz springs and have played with compression from all the way soft to mostly stiff with out much change. On the oregon dunes the trail whoops just beat the crap out of me and giving us whiplash. Not sure what to try while I'm still here. Maybe change pre-load? Or does it need valving done? Everyone claims how plush they are but not happy with setup so far either stock or new springs.
