One ton per inch doesn't sound too likely. Misplaced decimal? 210 doesn't seem terribly unlikely

oic what i did, its not the deg the shock sits at ,but the deg distance from 90deg. im guessing for the rear possibly 500lbs a corner, gives me a new rate of 80lb/in. so my dual rate would be 80/125?

I'd check the profender spring calc but that quality app just sits here



Total rate is A/2+B/2 isn't it?

for me it comes up at a 80lb primary, but no one makes an 80, so i went up to a 100lb. it says to use a lower that is 20-50 stiffer so i got a 150lb, i coulda went up to 175. so in the end i ordered a 14" 100lb upper, 16" 150 lower

1/R1 + 1/R2 = 1/Rtotal

Rtotal = 1/(1/R1 + 1/R2)

Rt = 1/(1/100 + 1/150) = 1/ (.01 + .006666) = 60lb/in

you will be soft with too much PL  (if you were shooting for 80 total rate)

80 on a 14" shaft at 50/50, with 2" preload would be 780lbs corner at ride.  F=R *X = 80(7+2) = 780lbs
60 on a 14" shaft at 50/50, with 2" preload would be 540lbs corner at ride.  F=R *X = 60(7+2) = 540lbs
