ESPO XHD stock or 1" drop leaf springs
You have the incorrect spring rate. You can have them dearched all you want. The spring rate is wrong.
Went through this with my bone headed cousin. After he wasted months dicking around, he pulled two leaves out and it sits correctly. If he would have listened, he would have saved a bunch of time and money.
Look up the stock spring rate and then look at your spring rate and my bet is your spring is way too stiff.
