I've been toying with the idea of changing the suspension on '11 F350 CC LWB DRW. At 1st i was thinking agout the r4 Tech from Firestone but after talking to a few dealers that used to sell it and, after reading some threads about it, I'm looking for something else.
My main question is has anyone on here have any experience related to the Kelderman 4 link suspensions for these trucks? And, also does the system let the truck keep the mfg. gvwr and tow ratings? Any in put good/bad or just suggestions/thoughts would be greatly appreciated.
It will probably be 4-6 months before i do anything.
