Ok guys my good friend has a pulling truck and we need new ideas on pulling suspesion for the rear

we have stops and traction bars but still have to much movement we need 2" of suspension travel

if you have any idea please chime in and can you help me out with some air pressure ideas what is the pressure you usally run

we run 25spi in the pack and 20 up front most of the time

last night we ran 30psi in the back and 25psi up front

As much as I'd like to chime in and say run 32.79lbs in the rear and 20.95lbs in the front, I can't and I doubt anybody else will either. There's too many variables here to give you any sort of "real" suggestion. Typically you find people running the rear pressures at or above max and airing down the fronts lower than the rears. To what pressure, that's the magic number and depends on an infinite set of variables like, tire (side wall deflection, plys, etc.), weight distribution of the truck, track condition, etc. Your best bet? Start a log book and start tracking it, change pressures and see how your truck reacts. Better yet, get buddy buddy with a sled operator (or find a test and tune day) and play with pressures all day long. But keep in mind, that's for that track, not another track. This is an art form of slip and grip. You air things down too much and have too much grip, it can hurt you if you don't have the power. Air the tires up too much, you set up on top of the track and never have the grip to begin with.

we have a long book but this is our first main season in pulling last year was practice this year for points

i guess we will have to find a test and tune that will be fun

thanks for your answer and help

Are you talking tire pressue? If so then 60 psi in the rears and 25-35psi (depending on track/weight etc.)

halerazor

what justin said 20-30 front and 60 or so in the rear you want the rear over inflated beleive me there will be plenty of traction on the rears

CTD03

dang thats alot of tire pressure in the year we usally run 30 psi maybe we are getting to much traction we have slow wheel speed the truck is built for speed we just cant find it out.

i guess your right there is plenty of traction being put down on the year when the sled come in play
saterday is the next pull new combination is coming out to try

i will keep yall posted on that one thanks for the great answers

post the trucks info...

CTD03

what are you thinking i cant do that

its a runner thats for sure

CTD03

pics of the truck its drag racing and that my friends dad running it.

that the same set up we have for pulling as we do for drag racing. but no weights in truck

Redline Ram

good luck then.

Do yourself a favor and quit being cocky about your truck.

You ask for advice about pulling and you have several people on this thread who can pull with the best out there in the street class who are willing to help.

We dont need to hear "its a runner"

When Randy "redline ram" asks you about your truck its to gather info so he can respond with some helpful information to accomplish your pulling goal.

So just be upfront and if you dont want advice dont ask for it.

i was writing him a pm about it so calm down there is tons of info i am writing i am in the process of doing it.

whats the point of drag racing a stick truck anyway? on the street for fun I can understand but a truck with same mods thats an automatic is gonna win everytime. I owned a 6speed before and an auto truck with half the mods could keep up with it no matter how quick you can shift.

Do the rules allow pulling with a front-mounted winch?

...as long as the weight class is adhered to?
