DORC AG's

[Branr1]

I want to start a thread that Shows each members with Ag's rig, and give specs so others who might be thinking about buying some can have an idea of what they look like and the Specs for each different kind.

These are the tire's I'm running on Stickers#2. They work great but they'll kill stock Rockwells. My set is sized at 18.4x26 which measures out to be 18.4 wide x 57.8 tall each tire weighs 277 pounds.

These are the tires Lesli is running on her Super Duty. There American Farmer 18.4x16.1 which measure out to be 18.4 wide x 44.8 tall. They work great and there priced right. We payed $1300 for all 4 brand new. Her truck has been running these for almost 3 years now and the One Ton Axles have been holding up great. We run ours on a set of Mickey Thompson Classic II 16x12 rims.

My tires are Titan 18.4x16.1 mounted on 16.1x16" wide steel rims with custom made centers for the Superduty 8 on 170mm bolt pattern. I purchased them from Windfoot tire in Anchorage for $440/tire and $150/Rim. The tires have increased in price to $510/tire last I heard. Tire specs are here: http://www.titanstore.com/info/48D890

If I had it to do over again I would go with a aluminum rim like Branr1 has, although I think a 14" width on these tires would be perfect, 16" does not offer very good bead protection and 12" does not give you as wide of a foot print. There is a shop that will make custom aluminum 16.1 rims that I will get someday. http://www.chuckstrucks.net/parts.html

I am running stock 1 ton axles with the following modifications; 5:38 gearing and detroit/rear ARB/Front. The front axle has a Solid axle hub conversion kit on it, and a Redneck Ram hydro assist steering ram on stock tie rods.

This setup worked well for me last year, however this winter I pulled a rookie move forgeting my front locker was engaged and turning hard right with some skinny pedal I broke the short side axle shaft. So I am upgrading to Chromoly inner and outer axle shafts because I told myself I would always do that if I broke the stockers.

I'd thought it might be helpful to add my personal experience with the upgrades to my drive-trains that have been essential to run these tires with high reliability.
The 18.4x16.1 I've owned have always been run on Ford 1Ton axles. I quickly found out that it was beneficial to upgrade to 35 spline chromoly stub shafts. I also upgraded one of my rigs to Chromoly inner and outer axles and I found these to be a great upgrade. I went with Yukon Axles from Randy's Ring and Pinion they never broke and there still in use with a set of AG tires they came with a lifetime warranty. I have always run Spice 806X u-joints in my one tons and as long as I replace them every couple of years they have yet to fail me. I also upgraded both my 1ton axle rigs to Hydro Assist steering to turn these large AG tires.

With my large 18.4x26 R-2 Firestone's I'm running 2.5 Ton Rockwell axles. With a tired 350 small block and a SM465/NP205 tranny and T-case, I've been able to break 2 Stock front shafts and 2 Stock rear shafts. Tires in this size range require upgraded axle shafts in the 2.5 ton Rockwell's. My current set up now consist of RCV Chromoly shafts in the front and Oversons Chromoly shafts in the rear. I haven't tested these out yet but I think they'll be the answer to my axle breakage problems. For steering I'm running a double ended ram full Hydro set up.

In my experience with AG tires you'll need to plan to do some drive-train and steering mods to your rig in order to keep it reliable with tires of this size and with there aggressive tread pattern.

I've had to change from the RCV front shafts to Oversons front shafts do to some design flaws with the RCV axles. The Oversons cost a little less and they've been holding up great.
