Another quesion. how much unsprung weight

[chris mc bride]

Was looking at spring ragte calculators. Asked unsprung weight. It is 60 panel but shoul be same as PU.

Seems axle abourt 350.

wheels and tires can get easy enough.

Seems spindles,brake assmebly , would think everything not supported by springs including lover a-arms,trailing arms and probably some stuff I missed.

Anyone every weight all the stuff that tires are carrying weight of and not pushing on springs?

Guessing 700 pounds would be cinservative and hell maybe way off base. Calculations only as good as input used.

Not sure how far you're wanting to go, but unsprung rear weight in a truck is one of the most limiting factors in how well they'll handle. A panel isn't as bad since the ratio of sprung to unsprung weight is better than a truck, but it's still pretty bad.

An IRS swap fixes that problem and gives you camber gain geometry and all around better handling and ride quality. I believe at one point a crossmember was available for C10s to use Corvette IRS, not sure if that's still available or if it fits a panel.

Like a good woman I want to go all the way.LOL By bank account says that not happening. In all honesty I am looking to basically make factory equipment with improvements fun to drive very nice old truck that is not the normal old truck.
Already told dad to ride over to grave yard and see if Pa's grave site showed signs of hoim spining is his grave with me cutting sides,floors out oif hius truck. He was never the hot rodder me and dad are. So walking line between hotrod and classic decked out truck.

Only asking about unsprung wioeght because part of calculation for spring rate for coil overs. While changing springs not that expensive it is still money that could be doing somethiung else.
