Sas Flex

ok so i am at the point were i get to pick my ride right

i have the stock coil buckets that were atached to the frame off b/c they are coming out about 2 inches

so i was thinking about going with eather XJ or Bronco coils not stock but lift coils that have good flex. but how do i determan how much they will sag under the weight of my truck.

for example coils that are 27" unloaded length & 300 lbs per inch (? WHAT DOSE THAT MEAN?) how many inches will they sag

so i can jack my truck up to what i THINK is a good hight in regards to the tire size (40") but how do i know how much sag there will be?


Help please

im pretty sure it means that for every 300 pounds of weight (force) they will compress an inch. So say there is around 900 pounds of force at each tire (i dunno the actual force; but id guess 800-1100 sounds right) it will compress 3 inches.

and 300lbs per inch seems really stiff for a light truck, i'd try to find some softer springs.

300 isnt bad at all. I know another TTB truck (97) weighs roughly 1100 on each corner. so if you use 1100 as your corner weight thats 3.6" of sag, then expect a little more as the coils settle.

would you guys recomend move the coil buckets down more or get longer springs .. longer springs would be better for flex right?

I would just move the buckets, a 27" coil extended is a pretty long coil.
