Rear axle weight with links and small tires: 482 lbs
Front axle with some stuff: 294 lbs
Tires and wheels: 161lbs ea
puts me around 1420 lbs unsprung, leaves me about 2980 lbs for sprung weight. figure prolly 60/40 weight split would be 1788 front and 1192 rear.
calcumates to 87 lb/in for the rear so 150/200
and 131 lb/in for the front so 250/300
i need to order springs, and that is rather convinient because i'll have pretty much every combination i'd need to dial in corners when all said and done that way. right or wrong, i should only need to swap springs one time if i'm guessing wrong when it is all done
edit: after talking to 4wheelunderground briefly through emails, he thinks those numbers are a bit high, especially in the front. i've reproposed 150/200 (86 lb/in) for the front and 125/175 (73 lb/in) for the rear. changed my weight bias guess to 55/45 and took an average using 10" and 9" compression for a 'goal rate' of 87.25 in the front and 71.25 rear.
math follows
![Homersimpson :homer: :homer:](https://data.irate4x4.com/assets/smilies/homersimpson.gif)
3000lbs * 0.55 = 1650 lbs/2 = 825lbs sprung per corner front
3000lbs * 0.45 = 1350lbs/2 = 675lbs sprung per corner rear
825lbs / 10" = 82.5 lbs/in for 3" preload and 7" shaft exposed, centered 14" shock
675lbs / 10" = 67.5 lbs/in """"
825/9 = 92 lbs/in for 2" preload
675/9 = 75 lbs/in ""
(82.5+92)/2 = 87.25 for about 2.5" preload front
(67.5+75)/2 = 71.25 ""
