5-ton front fender longer than deuce?

[rubicon_in_ga]

This is probably a total noob question, and I did a search but couldn't find anything pertaining to this... Comparing the Deuce and the 5-tonners, one obvious difference is the wheel well opening and front fender length. The 5 ton wheel well looks almost comically long to me. Just looks like the front axle should be positioned farther back/centered in the wheel well rather than having that huge gap. Is there a practical, logistical, or operational reason for this?

As you noted the 5 ton fender is longer on the M39 and M809 series truck from the Duece !! That is because the frame is slightly longer and the suspension is heavier !! also the Hood is longer on the M809 Series truck from the M39 !! The hood on a M39 should fit a Duece !!

Well, the Deuce is shorter than the M39 series both hood and fenders. And, the M39 series is shorter than the 800 series, both hood and fenders, and, the 900 series is different than the 800 series, both hood and fenders. So... parts inter changeability doesn't pertain to those parts, Roger that? JT

Its a look you will learn to like, trust me!

5 ton trucks run 11.00 20s 14.00 20s 16.00 20s and what ever you can stick under the fenders that is another reason the fenders are bigger !! Dave

I agree. I love my wheel wells on the 814. Just reach in and work on what you need.

They had to put longer stuff out there because the engine was longer.

I guess I just don't understand why they didn't shorten the wheel wells instead of running them all the way back to the cab steps. I can understand the engine being bigger and the frame longer, therefore needing longer hood, sides, etc, but why have the huge gap between the front wheel and where the wheel well terminates at the back of the fender? Don't get me wrong, I love the 5 tonners... just kinda a wierd look for me.

This is one of the aesthetic features I like most about the 5-Tons. The raked fenders give it an I-mean-business-look. But, as we all know with all things military form follows function. Seems to me, If moved father to the rear, the top loading differentials would interfere with the oil pan. It does make things easier to work on. Spencer likes to take cover under those fenders.

Great picture, Brian! Makes the truck look HUGE!

They made it so big so you can put 53's on

This is just speculation, but maybe the design and geometry of the front steering axle gives the heavier trucks more "sweep" of the knuckle and tire assembly during turns???

If the axle was moved back you lose the correct approach angle that the rest of the trucks have.

The cab of the 800 series is the same as the deuce so it was easy to just start the fender there. Im guessing the axle was moved forward for weight balance.

IIRC, The 2 1/2, 5 and 10 ton cabs are intechangeable. The fenders start at the cab and go foreward. At first, I thought the 5 ton fenders looked wierd, but after 7 years of owning and working on them, I think they're pretty cool just the way they are!

That's because they are HUGE!!!

yea thats a noob question for sure but really there are no better looking trucks in the world than all M series M series RULE!!!!!!!!!!!! so is the fender longer ? well the tire is bigger and there is more room around and behind it, ... just sayin could be... hope U have a sense of humor but really the approach angle to climb a 60 percent grade probably has alot to do with the placement of the axle, since this is the requirement of these vehicles... the load has nothing to do with it. approach angle could be..

Thanks, his Grandma took that pic of him. Spencer is actually 6 ft. tall. The pic gives one a good idea of how much room there really is under that fender.
