We all know what to do to the motor and tranny but for the chassis. Take a 2500HD RC LB 4wd and shorten the frame then put a short box on it. Take out the 34 gallon tank and run a stock 26 gallon tank or a fuel cell in the bed. Have a custom length driveshaft made up for the shorter wheelbase. Take the thick lower overload spring out of the rear spring pack. Add lowering hangers and shackles to the rear of the truck to level it with the front end after the torsen bars have been dropped. Ditch the stock shocks for a set of stiffer ones. Don't forget to beef up the stock tie rods. Pull out the spare tire, tailgate, receiver hitch and PS battery to save weight. Replace rear bumper with rollpan. Put in a rollcage and a set of upholstered racing bucket seats with 5 point harness. Add front and rear drivshaft loops along with a set of traction bars. Finally, put a set of slicks on a set of 16X10 aluminum rims on all 4 corners. I think I'll call it the Duramax SS. The SVT lighting and cobra guys won't know what hit them.

Add a front and rear drivshaft loop along with a set of traction bars and that should do it. I think I'll call it the Duramax SS. The SVT lighting and cobra guys won't know what hit them.
So Ah your new truck is in,I see !!!!!!

Use a composite bed, with the fuel tank over the rear end. How hard would it be to swap a Duramax into a 1/2 ton. The frame will weigh alot less. The main thing would be to get weight transfer with that heavy engine in the front, then 2wd could be used. How would slicks on all 4 corners handle? Wouldn't it get kind of hairy at the big end?

I think swapping a Duramax/Allison into a 1/2 ton would be more trouble than it's worth. That would also put the truck in the DHRA modified class instead of the street class.

The 4wd traction is hard to give up.

You'll have to ask kingD about handling, he's run 4 slicks on his truck at the track. It should handle just as good or better because there's more rubber on the ground than street tires.

While you are putting it on a diet, the rear axle from a 1500HD or 2500LD should be 50-70lbs lighter and still be plenty strong.

i gave up the 4 slicks in the 1/4 deal the front tires or slicks just dont have enough load capacity to handle the weight of a diesel and the thought of the tires letting loose at over 110mph have put a stop to 4x4 1/4s for me.maybe there a street slicks with better load ranges than what i have ,,,just dunno....jess

Don,t worry about the weight loss program.


Just make more HP!


7000# truck+(725-750 HP range) should be close.

Michael,


You have to retain the original wheelbase in Street Diesel and Pro Street sir.


It will take almost 900 hp to send a 7000# truck into the 10's. The aero dynamics pay a big part.


Michael, build a truck that is 5500 lbs and can easily be dropped with some lighter body panels to 4500 in the future, hint, hint, hint....
