I checked at the dealer today the pitman arm and trac bar have the same part # for the 1500,2500, and 3500. But the control arms (upper and lower) have different part #s for the 1500 and the others. Are the control arms on the 2500 and the 3500 longer then the 1500?? if so how much?

I dont think they are any longer I think it may be a bushing change ,because aftyer market lifts such as the skyjacker and the rancho don't use different arms for 1500 or 2500
