Here are some photos of my subframe. I had it done 3 1/2 years ago.

The first setup they welded across the ends of the subframe. That's not a great idea. You should never weld across a frame flange.
If you look at how the factory adds tubing to the bottom of an ibeam, it's stitch welded down each side. That lets it flex without creating a stress point.
The second why looks better buy an xbrace between them and stitch welds the sides would certainly help.

I added some tubing to an rv years ago, 1.5 inch square. Stitch welded the sides and reattached the hangers. tow another 7 years or so and it was fine.

But we all know rv frames never crack or have trouble anyway right?

I would watch the thin I beam main frame for cracking/bending next to where the old spring hangers are welded. That is a very high stress area now.
If thats the case he may have to box the I beam in the spring hanger area.
Good looking welds and job.

Thanks. I'm very pleased with his work.

I was in same boat as you a few months ago and went with the Sub-frame build over the Correct Track.

I thought I only need 2 inches but I was way wrong. My fab guy said I needed 6 inches and I am glad I trusted his judgment. I asked him to put extra holes in the new shackles for additional adjust too. It worked out great. Cost me $750 and I was more than happy to pay that after I got a quote for the Correct Track installed at over $1000.

I also upgraded from 15" ST tires to 16" LT tires which gained me another one inch in height.

Here was my thread on upgrading tires and adding the sub frame.

and I thought my 6" lift was a lot - wow

well back in line to use wfreeth lift method at the welding shop just have to wait my turn to get in. did score a set of steps today for after the lift - got the 4 step for a discount - heck bought 2 just in case my friend needs one.

Thanks Clif - they will be custom making them for this application so that should not be a problem. handy having them 20 miles away - my contact said I will be picking them up directly at the factory

Just remember the axles are arched. When you turn them over the arch is upside down. Tell Dexter what you are doing and have them set up correctly.
