I ordered a Fabtech add a leaf kit for my sonoma to stop it from sagging so much with a loaded bed and the new kit doesnt come with u bolts. The stock ones have maybe a inch of thread left sticking out, probably less. Do I need longer ones and if so can I just buy them at a auto parts store or should I look for some better ones online?

If you're uncomfortable with 1", go to a spring shop and have them bend a set up for you...takes about 10 minutes.

Okay thanks might just use the old ones. I just looked and I'm not sure we have any
dedicated spring shops around here, I'll call around

Stealth Conversions makes a nice set of longer ones if needed. Used them myself when I installed their blocks.

S-10 Truck, Heavy-Duty U-Bolts

Stealth Conversions U-bolts have the correct dimensions for use with the S-10 axle, whereas most aftermarket lowering kits are designed for a 3" axle. Also, most aftermarket U-bolts use 1/2" threads, which are weaker than stock U-bolts and often strip with repeated use.

Those are what I was looking for. Will they fit a 8.5 axle?

I always use the old bolts as they are better quality. 8.5" axles use the same tubes as the 7.5" axles. It only swells up the tube at the differential housing.

Yeah I got the add a leaf and its about a quarter inch thick so I'm just going to use the stock ones

I did AAL with the 2" RC kit. They get on all the way, but that is it. If you wanted to add another leaf you will need longer u-bolts.

Edit: Looks like you already figured that out.
