Increased payload

I know that modifications don't legally change any of the vehicle's official ratings or capacities, but what would be the real-world payload difference in switching stock Excursion rear springs with F250 springs? The F250 springs are rated at 3,000 lbs.

It's just like a Ram Mega Cab 1500 with its 8600lb GVWR. Just 1 lb shy of the 8601lb cutoff for HD emissions. A Mega Cab 2500 has a higher rating and the only difference is the sticker on the door jamb! It's all a numbers game. And in order to play you have to know the game. Some of us do and some don't!

Not exactly. The GAWR is based on the weakest link. Could be springs, could be tires, could be axle, could be frame. Unless you know which component it is, changing a single component might not change the payload at all.


Could just be fitting into a motor vehicle regulation and have nothing to do with the weakest physical length as well....

If you're super worried about the whole legal thing, get your truck re-registered for the front + rear GAWR. Depending on your local law, you may need an upfitter to re-certify a new GAWR, according to the axle's manufacturer's rating (not Ford's).

I switched out nitrogen in my tires for helium. It made the truck 203.662 pounds lighter which increased my payload.

Or buy tires with a lower load rating.

Friend of mine did this without even knowing it like most people do. His rear GAWR on his Ram 3500 SRW is 7,000 lbs. He went from the stock Firestone tires that have a 3,640 lb rating(enough to cover the 7,000 lb GAWR) to a 275/60R20 BFG T/A KO2 tire with a 3,000 lb rating. This essentially dropped his rear GAWR to 6,000 lbs which is 500 lbs lower than my 2500's 6,500 lbs GAWR.

Although, that sticker on the door is meant for OE tires per the law that made the manufacturers put it there. If you get something other than OE tires then that sticker is useless.


Is that the load rating for that 20" size or did he get a lower rated tire by accident? I put 18" KO2s on my truck recently and they have the same 3,640 lb rating as the stock Firestones.


Only that specific size. Some KO2 20"s have a 3,750 lb or higher rating just like some of the 18" KO2's sizes have less than 3,500 lbs rating. He should have known something was up when it said max psi was 65 on the side wall, but that is not always a good indicator for every tire.

I think he just did like most people do and just asked for specific brand or style of tire trusting the the person putting them on will get the right load rating for the vehicle.

Changing the springs does not change the anything.


Yes it does. It can change a lot of things.

Yeah, you are totally on the right track here. This is a super common swap.

Couple things to consider.

- There were about a dozen spring codes from that SD era
- After that many years under a truck, there is a decent chance that any used leafs are tired and not performing as when new.

If you have the means, any decent spring shop, should be able to make you a very nice spring pack to meet your needs for not a ton of money.

Do you have a 3/4 ton and you are putting 1 ton springs on or 1/2ton and putting 3/4ton springs on?

It's not really clear.

Well the X weighs approx. 7300lbs with no one in it. on my V-10 with its 8900lb GVWR that gives me 1600lbs of CCC. I`m not sure off hand but I believe a similarly equipped 250 is rated at 9500lbs (just below a cutoff of the 10k rating). and with an F250 being lighter than an Excursion by almost 600lbs that would give you approx. 2800lbs! maybe a bit less. I have the actual numbers somewhere from a V-10 F250. The Excursion is based on the 250/350 with 2 big differences. the frame behind the front seats is built differently to handle the body of the X and the springs were made softer to give it the mommy ride Ford was after when they built it, as well as making it lower to fit in garages. everything else is Superduty.

I run airbags on my X and it handles my 9200lb TT with no problem.
