I loved the 864's for my application (850, 864 with 1 1/2 spacers, ran 35 MTR, regeared)as well(before the 6''s extra heavy). 40gallon sub, drawer system, rear tire carrier, tools. Only towed once in a while. All real stable, not harsh in the rear. I beleive that the 864's are great if you have a constant load of more than 400lbs, anything less, it get jumpy, in the rear. The combo above was alot more stable on expedition type of dirt road traveling fast, then my currant set up. I some time wish I has saved the old springs and spacers for some trips that they were more suited for. later robbie
