Difference between the 24,000k and 26,000k 2021 F-53 chassis?

[Rvlegaleagle]

Was wondering what the differences are between the 2021 F-53 24,000 and 26,000 chassis?

2,000 lbs. lol…I don’t know exactly but my guess is larger brakes and suspension parts. Hopefully someone can chime in.

wider frame a few other thingies from my early reading,, but the builder i think has all specs..

[Rvlegaleagle]

Was hoping that some of you in the know knew the differences relative to a RV off the top of your heads...lol

The brakes are larger, leaf springs I think too but the carrying cargo capacity (ccc) (24,000 versus 26,000 and the towing capacity (5000 versus 4000 although the hitch is the same at 5000 was what I was wondering about.

Presuming you will use the full 5000 hitch rate on the 26,000 what is the difference between the two?

Thanks

Is there any other factors that makes one better than the other for RV purposes?

Before the 2020 chassis update, the only difference between the 24K and 26K chassis was the deflection rate of the rear leaf springs. Nothing else was different: axles, brakes, or anything else. Not very familiar with the new chassis, but I'd be very curious why you would now have different brakes between the two when you didn't before, unless, possibly, if they are making the 24K brakes smaller??

As for towing, if you need to tow to the full capability of the hitch, and you have the 26K chassis, then you just have to keep the actual loaded weight of of your MH at 25K or below because of the 30K GCWR. On the 24K chassis, by the numbers you are never able to get to a 30K GCWR because you are limited by both the chassis and hitch weight ratings.

That is exactly what I thought...you get essentially an extra 1000 pounds of carrying capacity by keeping it at 25,000 and use of the full 5000lb hitch...

I do think the brakes/drums are a little larger on the 26,000 versus the 24,000 was hoping someone would know that There could be other differences too.

Thanks for responding

I asked Forest River the same question and the reply I got from a senior management employee is that the installation of a 5,000 lb hitch on the 24,000 chassis is solely a safety reason.

There is no 7,500 lb hitch, at least not from their vendors, and they will not install a 7,500 lb hitch on the 24,000 lb chassis even though it can tow 6,000 lbs unrestricted.

He explained that they know people only look at hitch ratings and they did not want someone thinking they could tow 7,500 lbs when the unrestricted limit was 6,000 lbs.

If I was getting close to the 5,000 lb hitch limit, even on the 26,000 lb chassis, I'd have a reputable hitch shop replace the 5,000 lb hitch with a 7,500 lb hitch to give myself more safety margin on at least the hitch. Since almost everyone attaches their safety cables and breakaway cable to the hitch itself, if the hitch fails and departs the vehicle the breakaway cable will never activate the toad's brakes.

FWIW,

That's the link to the 2018 F-53 chassis with the V10 while the OP is asking about the new 2021 chassis with the V8. There are several suspension changes and drivetrain differences between the 2019 F-53 chassis and even the 2020 F-53 chassis.

The bleeders on the calipers are the same, probably same calipers. you can probably check if the pads are the same or larger on a parts website like napa, maybe rock auto.

Looking at the 2021 Specifications link above, depending on what the TBD on the Rear Leaf Springs details turns out to be, it would appear again that Deflection Rate will be the only differentiator again this year between the 24K and 26K ratings. Rear axle, wheels, discs and calipers are the same on both.

Actually not a techie and try to avoid anything Google or Facebook...a Google search gives you about 3 weeks of reading when out of your area of knowledge leaving aside the reliability issues but I digress

Figured there are many RV experts on this forum who know the answer in about 30 seconds not being lazy rather what I think to be efficient and most of you guys are smart, knowledgeable and trustworthy

Brilliant and thanks! Someone else on here in another thread suggested getting a welder to strengthen the 5000 hitch. I will be close to that towing this beast
