Need advice on what works best with dakotas for excessive wheel spin? My 60' times are awful 2.5sec. Was told to get 15" wheels and mickey thompsons or something sticky and streetable so I don't have to change tires at the track.

The 15" rims are so that you can mount taller, flexible sidewall tires which helps cut down on the spin on the launch ... overall diameter can remain the same if you want. DOT drag tires are for the sticky, soft rubber compound. These tires have the minimal number of treads and minimal amount of tread depth to be legal for street driving. As mentioned, one brand is MT Street ET. Others are BFG drag radials and ones from Hoosiers, etc. I personally do not run them on the street because they will wear too quickly and spin easy if the surface is moist/wet. These tires also let you safely/effectively lower air pressure, down to 12 lbs for radials and lower for bias ones.
Stiffer rear shocks will also help to plant the rears hard on the launch. Adjustable ones (e.g. from Rancho, etc.)lets you dial in the stiffness for the track and take it out for street driving.

He gets slow 60' times because he is spinning. You get them because you are SLOW, so no you shouldn't feel better about it.lol

traction bars stop wheel hop, not wheel spin. stickier tires for a high performance street racer will help a lot. Changing from a large dia wheel to a smaller one with a taller sidewall will not help stop tire spin, tire spin is increased the more the tire sidewall flexes the wrong way,. ever watch a top fuel car when it breakes the tires loose? the sidewall wiggles all over the place. MT's are a eally good compromise between a street/strip tire, but don't use them for everday use as they are not so good on rainy or snowy days.

You guys are bad at this! First, stiffer rear shocks will hurt you....Think about it, you want the ass end to squat and transfer weight. Stiff shocks will keep the weight from transfering, and you will spin more. Second, a smaller rim with more sidewall will hook up better! What do you mean it flexes the wrong way? It can only flex one way if you are on the gas and in a forward gear! The Sidewall gives a little so that the tread doesn't. For all of you uneducated, that means the tire will spin if the sidewall doesn't flex! Third, why would anybody in their right mind even try to drive drag radials, or slicks in the rain? Common sense..... wide bald tires suck on anything but dry pavement! He is looking for grip at the drag strip, not the cow field, or snowy mountain! Go with the stock style 15x8 inch rims, with about a 26-28 inch tire, as wide as you can get on the rim, and under your truck! Put them on before going to the strip, and take them off when you get home! Your truck would look gay with 17 inch rt's in the front, and 15's in the back anyhow!

There is another reason for traction bars.
when the truck is under hard acceleration, the pinion tries to move up. when you have traction bars adjusted correctly that upward movement makes the trac bar hit the front leaf eye. then the axle housing has no way to go but down, that pushes the tires into the gound. on a properly setup truck the rear bed of the truck will lift instead of squat. thats the traction bars pushing the body up and the tires down...
hope I explained this correctly

If the rear end squats that means that the rear shocks (and rear springs) are not pushing the rear tires into the ground. They are just compressing. "FOR THE MOST PART" you don't want the rear to squat because you want some resistance from the rear springs/shocks to transfer the force/weight to the tires. This can be proven. Make a coil spring out of a coat hanger and place it on a bathroom scale. Push on the spring. The scale is not going to read much because you are not transferring any force to the scale through the softer spring. Now take the spring out of your car and place it on the scale and do the same thing. The scale will read more pressure because it IS transferring more force through the spring. For shocks, this means having more resistance (stiffer) on the compression stroke. More important than the rear shocks are the front shocks but this about a daily driver who wants to lessen wheel spin on the occasions that he goes to the track and what you need in a front shock for the strip is dangerous for the street. Believe it or not, up to a certain point, anti-squat will help with traction.
I'm using adjustable rear shocks with 1 being the softest compression setting. At 2, the shock is slightly stiffer than the oem shocks. Experimenting over the past 3 years has shown that setting 5 gives me the quickest and most consistent 60' times.
> Third, why would anybody in their right mind even try to drive drag radials, or slicks in the rain?
I do not know the extent of 03 R/T's knowledge with drag radials so I thought it prudent to point out their limitations. I know quite a few drag racers who prefer the "street legal" drag radials so that they do not have to bother changing them at the track. Drying to the track might be dry, driving home might not be.

Good responses guys thanks a lot. I'm gonna look for a set of 15" rims and put a set of drag radials on them and go from there. Then I'll go with the 4.56's but, I need traction first.
