Help with flipping axles

I know a lot of you toy hauler guys have raised there trailers by flipping axles or building up the spring blocks.
Can somebody please recommend and good place to take my trailer to have this done in the Riverside Ca. area?
I just got a 2017 Ford F350 and it's a lot taller than my 2008. I'm not sure I can even back under it with the way the trailer is now at level.
Its crazy how high these new trucks are.

Thanks for any help.

I'm glad to see that the OP found a fairly inexpensive and effective fix to the height of the new Fords. Faced with the same thing with my new F450, I went this route:

These are 2" custom rear axle spacers (no taper) that lowered the bed height by approximately 1.5". This change, along with the same trailer spring mount hole adjustment as the OP, enabled me to tow level with 8" bed rail clearance. I use a hydralift motorcycle carrier so towing level is a little more critical for me than normal.

A update to my repairs and bed height issues. All repairs are done, and I'm very happy with the work VIP RV did to the trailer. Jim and his guys do great work. I didn't go with putting the axles under the springs. We only raised the springs to the lower spring block holes, which got me an extra 1.5". Flipping them would have been too much and on his recommendations I went this route. In the end I have 7.5" after adjusting the hitch head, pin box and springs. I'm happy with that.
They reinforced all the hanger blocks, did a brake and bearing service, some electrical repairs, fixed my AC unit and a few other odds and ends.
I highly recommend VIP RV service. Thanks guys for sending me to him.

Funny. We finally quit going to that CJ's for that very reason. We stop at Jack-in-the-Sack in Rosamond. There's a nice big dirt lot right next to it for oversized parking.


if I remember i park on the street but the lot in the back is so convenient!

I hit with my Dodge and don't want that scenario again. It was a nasty drop off at a campground. This is my golden years rig so going across the country will see major changing road conditions.
I've got to see a sweet spot somehow.

If normal on the road travel, 4-5" is fine.
Off road, going through culverts, lots of articulation etc, I would want nothing less than 6".
I have 7.75" between my bedrails and trailer.
I have come close once, but I was just crawling so I was watching it closely.

Jim @ VIP seems to think a axle flip will give me 4"/5". I think that’s all I need.
I'm going to hook it up this weekend and see what I get with the pin weight on it. That will be the deciding factor of what I need in the end.


4-5" is still real tight. I think I'm at 6" and it gets close on occasion. had the same issue when I went from 2005 Duramax to 2012. All the new trucks are taller and have deeper beds but not sure why. I assume newer trailers are taking this into account. My BIL just got a new 30' non TH fifth wheel and it fit his truck but was so low he couldn't get it in the driveway, had to actually lower the axles via a subframe, it's a little high but not too bad.
