Nice install!

Having been up close and personal with the frame Keystone uses on the Passport line, I would be skeptical if would handle some shock mounts without a lot of reinforcing. OP doesn't say the year, but prior to 2013 they used a frame made by Dexter, after 2012 Lippert, two different animals there. The Dexter frames were stout, the LCI are recycled soup cans.

The nice thing about Torsions is the tube acts as an additional crossmember adding overall strength. In the case of the Passport if it is a model with the LCI frame, the OP would want to add a tube to the bottom of the frame rail at least 2" X 2" X 4', probably top to bottom flange gussets inside and out at the end of it, and probably the Dexter 2-3/4" lift bracket between that and the Torsion. I would doubt he can not get enough ground clearance without doing if only counting on the start angle.

Haylet RV has a good video walk around and you can see that the spring hangers are welded to a 2"x2" tube spacer already.
I'm not sure the OP can actually lower his TT. Looks like the 2"x2" tube spacer is there for tire clearance.

Shocks, drop axel, depending on the actual weight of the trailer, lower psi in tires
Springs can also be designed to be softer. Is go with 5-6 leafs vs 4 with the same overall thickness.
Not sure of tire size. Example, if you have 235-85-16 10 ply tires, go to a 245-75-16 tire. About 1/2" smaller rsdious,, but carry the same wieght per tire. If you're using a 15" rsdious tire, there might be a smaller diam one, or ene a 14" that will carry 2500 or so lbs per.

More than on way to skin said cat issue.

Try this:
Dexter 5,500-7,000 torflex axles

What exactly are you trying to "fix" with the torsion axle?
As already suggested, adding shocks goes a long way towards calming things down suspension wise.

I would add shocks - makes a huge difference. I think you will be fine with it after that.
Lowering it a couple of inches isn't going to make a noticeable improvement.
