Why does the wheelbase matter when getting new springs and how do I find out what my wheelbase is.

Measure from the center cap to center cap on your wheels and use the closest catalog #

Wheel base matters because of the weight of the truck. That determines rating of your springs, or how much wieght they're rated for.

Okiespaniel is right, wheelbase and even engine options can affect the weight and therefore the spring rating of a vehicle. Interestingly enough, this info can also be used to provide a lifted suspension and stiffer, firmer ride for a 2 wheel drive vehicle. For instance, the 2nd gen 1500, 2500, 3500 and 3500 chassis cab rams all use basically the same front coil spring, only the spring rate increases as the gross vehicle weight rating goes up. Front coils from a heavier truck will fit in yours, but it will ride higher because the weight of the lighter vehicle will not compress the spring as much as the heavier one. You then only need to add leaves to the rear springs to bring the rear end up level with the front. I did this with my 2 wheel dr chevy suburban, I put front coils on it from a 10,000 lb GVR chevy box truck that had the standard pickup/suburban cab, giving 3.5" of lift to the front end. We then added 4 leaves to the rear leaf springs to raise the rear by 3.5", and 2 ton shocks all the way around. The result is extra ground clearance when I run my suburban off road, plus a much more controlled ride when I'm lumbering over rough terrain. The truck has much more responsive handling, cornering, and a firmer highway ride, and I can tow a 10,500 lb trailer and the rear end sags less than 3/4".

I was thinking about using a heavier rate spring cause I wanted to level it anyway. I was thinking about using some half ton 4x4 spring to keep a relatively smooth ride, should that work fine. Have you had any problems with alighnment, I ask because thats the reason I need new springs in the first place.

I'm actually not positive if the 2WD and 4WD Ram springs are exactly the same in the base and top dimensions. This is what makes them fit or not fit. All of the guys I know have 4WD ram trucks, so I have never gotten an up close and personal look at the 2WD front coils, although I think they might be swappable. One way to tell for sure is to look at a spring catalog from a parts place that has the base & top dimensions listed, and look up the spring for both the 2WD and 4wd version of the same year. If the top and bottom dimensions are the same for both, you can swap them.

Will the 4x4 springs work on a 2wd??

Absolutely not! Physicaly they're too long...

If you're trying to lift your truck buy the proper parts...spring rates can determine whether your truck is safe or an ill riding poor handling death trap.

I was fairly certain they wouldn't but I figure would ask for the op's and mine sake considering we both have 2wd

Are they too long? Tall I guess would be a better term... anyhow, never saw any coils from a 2WD, so don't really know about that. However, the 2.5 ton front coils I swapped into my 1/2 ton suburban were taller than the stock ones, (and made of thicker steel too) but the base and top were the same diameter as the stock ones, so they worked just fine, only they were a ***** to compress and get into the A frame because of the extra height. However, when all was said and done and I got 3 new leaves made for my rear springs, I ended up with a 3.5" lift kit on my 2WD chevy suburban. Handles stiffer and snappier than stock, more like my '79 corvette stingray than a suburban. Anyhow, I think stuff like that is largely subjective too, what one person likes and is looking for in ride and handling characteristics might be horrible to another person. Personally I have never liked that boatlike, dip and sway, soft cadillac kind of ride on any vehicle. So the now harder, tighter ride on the suburban was just what I was looking for. Plus, I can tow a heavier trailer, have a tighter off road ride with less dipping and bottoming over rough terrain, and I can drift her around a U turn at 45 mph and maintain control. I have lifted a lot of vehicles over the years by using heavier duty springs off a heavier vehicle (you'd be surprised a how much GM stuff is physically swappable from one vehicle to another, allowing gearheads like me to create what is and what never should be) and I can honestly say I have never had this cause a problem with control or handling. I do use heavier rate shocks to go along with the heavier springs, and of course the ride characteristics are often radically changed, but it cuts down on a lot of things that are often considered undesireable... front end dip, body roll, understeer, excessive bouncing or dipping when going over potholes or large bumps. I even had a Chevelle with a suspension from a 5000 lb vehicle on it that I managed to get airborne once with no ill effects.
