I'm assuming you don't have #s from before you replaced the shims. See what SPC has on their website for shims, you can do the math now that you have #s to work with and put what you need in to bring it back out to where you would be satisfied. It's a really informative website. Also, as stated here many times, heavy truck shops are a better bet than a normal alignment shop or dealer.

it actually was a truck shop. The one we use for our company trucks.
I don’t have stock numbers and I don’t have leveled before shim numbers.
just the ones posted above where they didn’t touch caster. What are the chances this truck is tapped out the way it rolled in there and they could t add any to it?

The only way they could change caster would be different shims.
Not sure, the most I've seen mentioned are 2.6*. I wouldn't think there to be too much more than that. Were the sleeves included in the kit SPC, and does it say the degree on them?(Pic is blurry)

Looking at SPC, the highest degree that comes up for your truck is a 2.6*. Obviously that wont make a difference over your 2.5* shims. Looks like you may need to look into the radius arm drop, although it would be nice to know why yours has such low caster.

Agreed, very strange where your #s are right now. I wouldn't rush on buying something, research the options. I do know that more adjustable the aftermarket parts are the better off you will be. When you look at the really tricked out trucks, everything has lots of adjustment. You'll end up with a really great set up when all is said and done, you just may have spent a little more money than you expected. But hey, vehicles are the worst investment out of all major purchases.
They do drop the rear of the bracket but not as low as the axle attachment. So I really don’t think you loose clearance. You will hit your axle before the drop bracket becomes a problem. Supper easy to install. And takes the bow out of your springs.
I see a couple positives here but they also leave me with a few questions.
1) how much caster do the bds arms correct for on a 2021 truck?
2) says they’re built differently than oem arms and allow a little more tire clearance. That could be a huge plus….think I could fit 37x12.5 on stock wheels without rub using these arms?

That screen shot is from the 2015 product release. They do include those, or similar radius arms, in their radius arm lift kits, but do they also sell them separate? They claim to offer caster correction and they would keep larger tires from rubbing on the radius arms.
There isn't a lot of caster in these trucks from the factory. The shims you removed should have markings on them. These were mine.
You lose roughly 1° of caster for each inch of lift with the spacer. So if you installed 2.5° shims on a 2" lift you should have ended up with roughly .5° of caster on top of whatever is there with a 0° shim.
In other words, those shims put you back pretty close to stock. The drop brackets are a better solution, especially because they will reduce or eliminate the angle on the coil springs.

are some of the 2021 trucks coming with roughly 2° caster from the factory?
