Hey guys - I'm building an FJ55 w/ 4 link rear using factory TJ coil buckets. Since this is a wagon = want a heavier spring rate, I assumed the Grand Cherokee coils were the same config. (top & botom spring taper) as TJ's only a heavier spring rate. I guess what I'm asking is are the rear springs from a Grand Cherokee always tall & skinny or were they ever the same as TJ's (wider & small taper top & bottom) ? Thanks!
