Hey don cant help you with XHD, but I had my springs done on my 67 Coronet..BIG BOAT and they lasted for years...lifted the *** end up about 1 1/2" gave it a real nice lean...they had the car for a couple hours and I think it was around $150??? I was happy with them give them a shout...Moi Parry Spring Service in Peterborough 705 742 2329 talk to Kevin. He also did the springs for my cuda....but like everything else with it, I havent put them back on yet. I took them in and he charged $100 with new bushings in the back end
