Im in the process of specking out a new truck, and dont know what rear end gear ratio would be ideal. Tranny will be 6 spd Ford manual. What do you suggest for light duty pulling...almost exclusively pulling a mowing trailer which will be 16' enclosed with 2 mowers. Truck may be used for plowing in the future (far off if ever) Thanks for the help. ;)

Depends a lot on the truck/engine choice. In a Dodge, with a Cummins engine, I think a 3:55 is best, unless you'll be doing a lot of heavy towing. Then 4:10 would be best.
What trucks/engines are you considering?

My new F250 has 3.73 gears in it. Seems to have plenty of pulling ability. Gas mileage isn't great, but not as bad as 4.10's would be.

It would depend on which engine?And if its 4x4,what size tires I was planning on running.

I bought my GMC with a 4:10. It is rated to tow up to 2000 lbs more than the 3:73, 10,400 total. It also gets 12-14 mpg, better than my Dodge with nothing in tow. I would see what the total towing weight is you are going to be hauling. I have actually been getting better gas mileage with a heavier truck, bigger engine and lower geared rear end. Go figure.

thanks for helping me along so far.

Truck in question is a '03 F350 srw 4x2 with 5.4 gas and the 6spd manual. As i said, trailer should amount to approximately 5000 pounds maybe? (16x7 enclosed, 2 wb mowers, not much else). it wont haul anything more than that but maybe twice a year. It will be primarily a mowing truck. Hope that helps you help me. hehe

5.4 a 4.10, with 6cogs it'll still run a 100.-a 6.8 is just 600.00 more.A 3.73 would get a couple more mpg,unloaded,but in a gasser I like a 4.10..I'M going to be honest with ya--PUT a 1 ton ford under a load 5.4,6.8,3.73,4.10 it dont matter,you wont get 10mpg.SO get some motor and gear.OR spend 5more k and get a powerstroke.

I have 3.73's also, brother has 4.10's in his, gets alot less fuel mileage then mine. But I cut out the muffler and put a airraid intake on mine. sounds great and helps with the towing power.

If your going to be pulling alot get the 4:10's. if your concerned about gas get a powerstroke.

thats the best thing to do, get a P/Ser, heck my enclosed trailer weighs more empty then most fully loaded.:)

I'd go with the 4.10's a buddy of mine has this combo in a 250 and he pulls 10,000 rugularly and has no problem. I hope you get your order in soon I picked up a brochure from ford and in '04 it only shows two engines the 6.0 and the v-10

If you have any thoughts of ever plowing with the truck get an automatic and 4x4. As far as the rears, i would go with 4:10's.

After owning 4 of them since 96 you can avr. 13mpg.

Pulling a 5000 lb. trailer, I would get the 4:10 in that truck.

I'm more concerned about why you want a manual transmission than what the rear end ratio will be. The auto trannys today have come along ways and will probably be less maintenance than a stick will be. Pulling just a mowing trailer is no big load if your concerned about pulling power or ability. Our International dump truck is stick only because it was what they had on the lot. Next time, I'm ordering an automatic. The big Allison trans in those trucks are just about indestructible and work quite well from guys that have them and shop maintenance records.

I have a 3900 lb trailer (empty) loaded with all misc hand equipment, a hydro w/b #650, a 1150# and a 1350# ztr rider mowers. I have 3.73's and very, very seldom will it kick off the O/D. But this is a P/Ser, so with a gasser you will probably need all the help you can get. I had a 99 f-150, with the small 4.6, honestly a good gust of wind would make it kick down.

I think i will, along with the v10 and 4x4. If im going to buy, i might as well make sure it will suit me for a loooong while seeing as i put 2000 miles on my truck this year.
