good lord... was it really that easy?

ok so then check me....

my front gross axle weight is 3,240lbs
my spring rate is 227

so i would divide 3,240 by 2 and get 1620

then i divide 1620 by 227 and get 7.1

so each coil will compress 7" with the trucks weight on it

correct?

No.
take 3240 minus the weight of everything not held up by spring (rims, tires, axle, hydro cylinder, etc) then devide by two for each spring, then devide by 227.

so im pretty much going to be only subtracting the weight of the tires and the old IFS suspension? would 500 be a reasonable weight to subtract? i also have another question. while looking up the weight of the truck the website i was looking at stated the front gross axle weight and the rear gross axle weight. but the weights were the same. should the front be higher then the rear due to the motor?

gross weight is the MAXIMUM weight, and it has nothing to do with what you're doing.

Go get the thing weighed.
This is true.. He needs to know curb weight is the published spec that refers to the rig weight. It's not a perfect number but an okay estimate. And it is sprung and unsprung weight.
