I own a 2019 Crew Cab F-350 Diesel. FX4 package and Lariat Sport package. I do tow. Currently it is a bumper pull 8,500 lbs loaded trailer. I plan to upgrade to a Fifth Wheel Toy Hauler at 16,000 lbs loaded. I'd like to lift my truck (3-4 inches) for some 35s or 37s, and would like to keep the rake so that once loaded it sits level, without compromising towing ability, within reason. I'd like the lift to include upgraded suspension (schocks and springs) that is better for loads than what I have from the factory. Also what are best the best looking AT tires that are just as good if not better for heavy loads compared to my factory tires. I would be keeping my factory rims, because I love the black lariat sport 20's.

I'd like to see what you all have done, and what I can expect to pay. Pics and experiences are most welcome.

 

I’d caution you about lifting your truck if you plan to tow a 5th wheel. Even stock, many people have had issues trying to keep their 5th wheel anywhere close to level since these trucks are so tall in the rear. Even with various types of hitches on their lowest settings, the trailers can still be nose high. Slightly nose high is normally fine, but add in another few inches and it’s very hard on the trailer suspension.

 

I agree with what slapshot12 has just stated....plus....you are already going to be pretty close to the payload capacity of the truck with a 16,000 lb fifth wheel trailer. In fact, I would venture an educated guess that you will be overloaded when you are fully loaded on the trailer. 20% of the 16K is 3200 lbs, plus the weight of a 5ver hitch will put you close to another 200 lbs. You can check the door sticker on your truck for the payload capacity, but again, a guess is going to be 3400 - 3500 lbs of payload. That pretty much leaves you with zero extra for passengers, and anything else that you put in the truck or in the bed of the truck. In most instances, 16,000 lbs of trailer would be better served using a Dually for a tow vehicle.

 

Unless you also lift the trailer, it's not going to sit anywhere close to level. You would likely have clearance issues also.

It isn't always an either/or answer, but usually it's either tow a fifth wheel trailer OR lift the truck. How you lift the truck can also make a difference. Some of the aftermarket leaf spring packs that provide lift can be very soft, which usually means lots of squat when weight is put on the rear axle.

 

I hate being the weight police, but lifting the truck could totally screw up the suspension ratings. Just like airbags do not raise the ratings, even though the increase capabilities, unless the lift manufacturer has gone through everything to get the GVWR increased for you truck, you really do not know what it is capable of towing, or how much weight whether pin weight, tongue weight or cargo weight it can handle.

 

like they said above..keep it stock if you are going to tow a 5th wheel.

 

You dont need a lift for 35s or any of the metric tires between it and 37s.


If you do like 1 inch for looks I get it but maybe avoid lifting the rear because of the 5th wheel.

 

I think FoMoCo *lowered* the SRW truck in 2020 because they found out they were too damn high practical for 5th wheel use.
If you MUST have a lifted truck, just buy another truck to pull 5th with, or spend bucks to lift trailer to match truck, and with many 5th wheels already being 13’6” high, proceed with caution.


There *might* be places you can’t get to with a lifted 5er.
