ride with the diesel coils is slightly stiffer then what the hemi's will feel like (i know b/c my buddy has the same truck w hemi coils), but its barely noticeable in my opinion (he agrees with me as well). Either set is a huge improvement over stock. and my buddy actually wishes he had put in the diesel coils b/c he plows as well, and there is a little too much sag in his front, and sometimes his 35's rub a little, where as i don't at all. Also with the plow his truck rides alot rougher compared to mine b/c of the extra weight. So my advice to anyone running a 2500 hemi should get diesel coils if they ever plan to run a plow, or add a heavy bumper/winch. so all in all, everyday driving hemi vs. diesel coils the difference is barely noticeable if at all, but the difference with added weight (plow or bumper) the difference is HUUUGE! and by the way, the hemi coils end up costing another $30 extra sometimes, and are harder to get b/c carli manufactures 1 set of hemi coils to every 3 set of diesel coils. I can get you some pictures end of next week at the earliest b/c I'm actually on vacation right now.
