how much diffrence is the tow capacity of 1/2 ton front coils and the 3/4 springs... i want to lower my 4x4 in the front 2 or 3 inches.

 

A. This is in the wrong section.
B. Your truck is gonna ride like complete crap with springs made to support a 318 when you have a Cummins in there.

 

I agree, a 318 weighs what, not much, our cummins weighs over #1000. would not work well.

 

Jimmy Smith's drag truck that run's mid 9's uses half ton springs up front. Im pretty sure you can just bolt them in and go. They should get the few inches lower that you are looking for from it. His truck also has a set of monster twins, data system, and plenty of other extra stuff that weighs the front end more, and he hasnt had any problems with them yet. Those that havent tried it wont know if it will work or not, and are just guessing at it.

Here is a video of a 9.7 run.

whats the truck going to be used for? if its just a drap truck then maybe. most drag trucks are light in the right end. my 2wd wieghs 6300 lbs

 

I have not seen too many potholes & driveways on dragstrips yet have you ?

 

its not going to be drivin much at all just a lil pulling.

 

So, that means you're just going to add MORE weight to the front. And, you're on dirt, which isn't as smooth as asphalt the last time I checked. What I would do, (take this as you want) would be to get a set of one ton springs and cut them down a few coils.

Ok, did some research for ya on google since I'm bored as hell at work.

Numbers's on left are "tag numbers". And the number's to the right are load ratings in pounds PER SPRING. Half ton on top, 3/4 on bottom. I found this on a snowplowing forum.. So, I'd take it with a grain of salt.. But, if these are correct, there is a 1000+ lb difference between 1/2 ton and 3/4 & 1ton front springs.

If anything it will soak up the bumps better

As long as you still have enough room for some axle travel(which could easily be measured before you did anything), then it should be fine.

 

the way i c it is i only asked a simple ? and yall blew it out of frame... thanks rodp 99 u acualy anwserd my question.

 

Glad I could help. So what are ya gonna do?

 

i think ima run half ton coils and strap th front end during pulling and just stock stuff during the rest of the time.
