Which gears for 33.7" tires?
#16
the 9.75 is under any F150 that has a 5.4L
#18
whats your door code say under AXLE?
#19
the point of this thread was to help the op deside what gears to pick. not talk about the 10.25 axle in my tuck! i was trying to help him see the real would rpm he may see! if you want to know more about the 8200 gvwr f150 heavy duty you should start a new thread asking about its specifics or you could search: "how common is this? - heavy duty package" that should help you out!

you dont have a 10.25 in your truck and you dont need to be talking about stuff you dont know about.
YOU HAVE A 9.75 REAR END. YOU HAVE 3.55 OR 3.73 GEARS. IF YOU THINK YOU DONT THEN POST THE INFO I TOLD YOU. PRETTY SURE THE OP KNOWS YOU ARE FULL OF CRAP AND NOT TO TRUST WHAT YOU SAY ANYWAY. I CAN CONTINUE TO MAKE YOU LOOK STUPID. PROVE ME WRONG

Trailer Towing/Camper Information
NOTE: Refer to the 2008 RV and Trailer Towing Guide.
Snowplow Applications
Minimum required equipment:
F-150 4x4 144.5" wheelbase Regular Cab and 163" wheelbase SuperCab model
• Heavy Duty Payload Package(1)—Includes:
— GVWR—8200 lbs.
— Axle, rear—5300 lbs. (10.5 ring gear) and 4.10 axle ratio
— GAWR/springs, front—4050 lbs./4050 lbs.
— GAWR/springs, rear—4800 lbs./4900 lbs.
— Frame upgrade (.150" rail thickness)
— Super Engine Cooling
— 72 amp-hr./650 CCA battery
— 9-channel (18-plate) oil-to-water auxiliary transmission oil cooler
— LT245/70Rx17D BSW all-terrain tires (five)
— 17" x 7.5" J 7-lug steel wheels
• Powertrain—5.4L 3V V-8 engine with 4-speed automatic overdrive transmission (4R75E) (when snowplowing, operate
automatic transmission with shift lever in overdrive position)
• Fuel Tank, 35.7 (135 L) Gallon Capacity
• Snowplow Prep Package(1)—Includes:
— GAWR/springs, front—4300 lbs./4300 lbs.
• Recommended weight limits:
— Regular Cab 695 lbs. (645 lbs. removable plow assembly + 50 lbs. permanently attached hardware)
— SuperCab 535 lbs. (485 lbs. removable plow assembly + 50 lbs. permanently attached hardware)
• These snowplow weight limits are based upon a vehicle built with maximum buildable Ford option content, driver plus one front
seat passenger, 150 lbs. each, 800 lbs. of ballast weight rearward of the rear axle and additional assumptions for
commercially available snowplow assembly weights and mounting location
• Exceeding these snowplow weight limits may result in the completed vehicle exceeding its load rating as shown on the Final
Stage Manufacturer Safety Compliance Certification Label
Completed Vehicle Weight
The weight of the completed vehicle with equipment installed (and second unit body, if applicable) must not exceed the Front
GAWR, Rear GAWR or GVWR established by Ford. If sufficient weight is added such that the completed vehicle with a driver
and more than one passenger would exceed Front GAWR, Rear GAWR or GVWR, it is the responsibility of the equipment
installer to notify the customer of the appropriate use restrictions (i.e., that the user should limit occupancy of the vehicle to the
driver and one passenger while the equipment is installed). The addition of ballast weight, placed rearward of the rear axle, may
be required to prevent front end overloading or exceeding Front GAWR. If required, the ballast weight must be securely attached
to the vehicle. For Ford completed vehicles of 10,000 lbs. GVWR or less, the weight of permanently attached equipment must not
exceed the Total Accessory Reserve Capacity (TARC) as specified on the Safety Compliance Certification Label. Permanently
attached equipment includes the snowplow frame-mounting hardware, and does not include the removable snowplow blade
assembly. Exceeding TARC will require recertification.
Front-end Wheel Alignment and Headlamp Aim
Front-end wheel alignment (toe) and headlamp aim may require adjustment after installation of equipment, and is the
responsibility of the equipment installer. Failure to reset front wheel alignment may cause premature, uneven tire wear. If required,
reset to chassis manufacturer’s specifications found in the Ford Shop Manual.
Electrical Connections
Installation of any inductive load devices (i.e., electric motors, electric clutches for clutch pumps, etc.) MUST NOT be connected to
OEM wiring or fuse panels. Power for such devices should be taken directly from the battery or starter motor relay power
terminal. Control of these devices should be achieved via relays. No direct current path should exist between OEM wiring and
the installed load that is not filtered by the battery. These recommendations are intended to reduce or eliminate any induced
reverse voltage into the OEM circuitry.
Warranty
The Normal Ford New Vehicle Limited Warranty applies to vehicles with snowplows installed in accordance with these guidelines.
Consult your Ford dealer or the Owner’s Guide for any further questions.

go get yourself a camera. take a picture of the door tag... its inside the door jam.
i can pull up countless articles that say my truck should have this and that when all in all IT DOESNT.
not too hard to change any of that either. You have still proved nothing. Im done with you.

Okay, children - take your squabbles out to the playground at recess.
Long, that data sheet is for a 2008, but don't you have a 2007? You might want to check the accuracy of things you are posting when you are butting heads with other members.
Trimble, don't you have better things to do than flame other members?

Until '09, the 8,200# package had a 10.25 or 10.50 axle, along with the stuff listed above (with slight variations over the years). Until '09, they also had 4.10 gears, but the '09 has 3.73:1 with the 9.75 Sterling axle.
There's very little difference really between a 10.25 (actually called a "10.38" in the spec sheets) and a 10.5 semi-float axle. Put the ring gears side by side and I'd challenge you to tell one from another. There can be differences in the pinion, with the 10.5 having a thicker head. You can use a 10.50 gear set in a 10.25 housing if you grind a little off the 10.50 pinion to clear the 10.25 housing (which is slightly different than a 10.50 in the pinion area). It would make more sense to consolidate housings to have only one. It's possible (but I don't know) that what they have called the late model "10.25" is actually a 10.50 (what's a quarter-inch among friends?).
To answer the OP question, 4.10:1 or 4.56 would be a good choice for 34 inch tires. FYI, I have monitored trans temps tall gears and big tires, and you can see a big jump in trans temps. From 235/75R15 to 31x10.50R15 with 3.08 gears, the trans picked up almost 30 degrees of heat (on a GM truck) in a little course I designed to test the effect (more heat in the 'wheeling arena). When I went to 35s (34.5" mounted), it jumped up more than 40 degrees and 'wheeling, the trans quickly got up to 275 before I had to stop for a cooldown. When I installed 4.10s in that same truck and on the same course, the temps with 35s dropped to slightly below what the stock temps were. There's a big difference in trans temps! May not matter much for people who don't work or 'wheel their trucks, but if you do, gears could be the difference between a cool tranny and a pan as hot as french fryer.

The truck is mainly a daily driver...I have a 60 mile round trip commute to work that is about 75% highway. That commute is likely to change soon though and become closer to 50/50 highway/city. I do use the truck on occasion on my parents farm to tow hay/corn wagons or haul a load of hay or fertilizer in the bed. The towing or hauling only happens 10-12 times a year or less and it is for pretty short distances. I think you already know this but keep in mind this is also the 5.4.

Thanks for the info on the 10.25/.5 i did not know they where that close to each other!
if i have this right your truck was the one in the 4wheelparts mag! if so do you think you could start a thread with digetal copys of the articals? There is good info in there and i think it will help people.
