Possible to convert 17.5 over to 22.5

The tires themselves are 37.5" overall. However you'd need a few inches of suspension travel plus physical height of the decking.

 

I noticed looking at a few Talbert 55 on Truck Paper had a few listed as 18" height, most as mine are 20", a dealer in my area had 2 in stock and when i looked at them they were 20 inch decks, i wound up going in a different direction and glad i did because when i decide to switch out my 55 i am going to go with a drop side, loosing too many jobs that are in the 14'4" to 14'6" range.

 

You can get an 18" deck height, a drop side will get you close to 12/14.

 

I was just looking on there website, the SA is 20" deck height with a 25' deck, the CC is 18" deck height with a 26' deck, salesman never told me that.
The DS/RC on the 55SA is 15.5 inch deck height, also the SA is a 50" 5th wheel height, the CC is 52". i learned more in 10 minutes reading the website then i did with the 4 hours at the dealer.

 

You can get the SA in an 18" deck height and you can get the fifth wheel height pretty much where you want it. They do a LOT more than is on their website.

 

I thought it was misleading because i have a 55SA and my 5th wheel height is higher then 50"

 

They change specs all the time, but they'll build whatever you want.

 

Good to know, Thanks.
