New Truck Too Tall to Tow

**Grandesigner** · 10-17-2022, 03:02 PM

Just got back from picking up the new F350 4x4 and bad news is that it is 2.5" taller in the bed above the axle and 4" taller at the rail above the axle, than my old F250.
With my old truck, the 5th wheel already tows a bit nose high, so it looks like mods will have to be done before towing with the new truck.

The new truck has 2" blocks under the leaf springs so what are my options to lower the suspension a bit?

Also, I may need to raise the 5th wheel a bit since the hitch itself is already in the lowest position. I was thinking taller tires before raising the suspension on the trailer.

Thoughts?

Has anybody here raised their 150 Series 5th wheel a good 3"?

Were the blocks on the TV dealer added? There's a ford dealer in Ottawa that modifies they're truck as soon as they roll in and then forces the customers to pay for it or walk.

Nope, completely stock.

Here are some lifts for the axles on the trailer.

Pretty common issue with trucks and fifths. In my case, when picking up my old fifth, the dealer installed a "lift kit" on the fifth to get it up to the proper height. Most good trailer shops should be able to do the same, easily. No need to modify your truck.

Depends on what trailer you have and how tall it already is. Many of these trailers are already pushing 13 and a half feet.

How high are the bed rails ?

That was one of the reasons we bought a Dually, Normal Sized Tires. The single rear wheel trucks have 21" - 22" inch tires in them making them too tall for our 5th wheels. Additionally, the larger tires make the truck harder to get into.

PS: Our Dually has 17 inch tires.

Those are rim sizes which doesn't always corollate to the overall height (the important measurement) which has an effect on truck height.

The OP has a 150 Series 260RD. GD specs show a height of 12' (I don't know if there's an option for a second AC up front). Sounds like there's room to grow.
