you never see anyone do it. Usually you see people dump the drum brakes, and get an inset rim like a hummer rim to narrow it up. But that still leaves you awfully w i d e. Am I missing something, or is there a reason nobody narrows them? I'd like to see a rockwell setup that's about 80" wide outside of tire to outside of tire. Can it be done? <IMG SRC="smilies/ghost.gif" border="0">

According to this thread:
http://www.pirate4x4.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=10&t=012821

(the post by elf), with the the hubs flipped they are 67" wide. With 4" backspacing on a 15 x 10 (the max it says is permitted), that puts the center of your tires 69" apart. With a 15" wide tire, that puts you around 84" total width, which is still narrower than my D60. Not quite 80", but close. I wonder if you could use more backspacing with a 16.5 rim? Or am I missing something? My 60/14 bolt setup is sure starting to feel inadequate lately with all this talk of portals and top loaders. <IMG SRC="smilies/blush2.gif" border="0">

Dont know about the rockwells, but I am sure it can be done. I cant remember what the axle was thats under Quagmire, that big red and white Chevy that has been in the 4x4 rags quite a bit a couple of years ago. It was even in the TTC a few years back. Anyway, they showed in the mag how they narrowed a similer axle.

unimog way lighter
and sweeter ground clearance
like the new bronco Eric at Fat City Built

the axle was built By CTM now thats something to talk about!!

My.02 cents

I think that axle in Quagmire was a 5 ton Rockwell center with like Dana 60 outers on it.

Don't see any reason it CAN'T be done. Reason you probably haven't seen it yet is that Rockwell's are typically used with VERY large tires. And the extra stability of the width is probably welcomed. And width isn't really a handicap in most situations where a Rockwell would be warranted. ARCA being the new situation where width IS a handicap.

Boyce Military Equipment has 2.5 ton Rockwells that are narrowed 7". This may be the solution to the width problem.:bounce: :bounce2:

Would it be that hard to just get a rockwell dropout make a mounting plate then weld up a housing, like the Titan? The only problem I could see would be attaching the axle tubes so that they woulden't bend. You could just use 1.5 ton (D70?) flanges and knuckles. I dont have much faberication experiance, how hard would this be?

it won't get you down to 80", but you take the rockwell housing, cut the long side tube 7", & a short side axleshaft will slide right in.
One of these days I'll have to get pics of my buddies chevy, his is narrowed, then he turned the pinion up too... pretty damn cool. & yes, the truck is huge. He's sitting over 48x25 Firestone terra tires. Scary part is it rides like a damn cadillac & drives straight as an arrow at 65mph.
And yes, he drives it on the street... don'tcha wish you lived in AZ too?

oh, & BTW, to the best of my knowledge, you cannot flip the hubs on the front axle... only the rear... all fronts were the same, the rear is flippable depending on wether it's a single wheel or dually truck. Dammit, I owned a truck with these axles for a while, but I never really paid much attention. it did have the axle narrowed by the "cut 7" method" I described above though.

Mogs

I still think Mog axles are the way to go, the CTM axles are super trick but they are 7500US or somethin like that.
I sell my Mog axles for 2500per set or 2750 for two fronts, and this includes the pinion conversion. You get all the low gears and selectable lockers with it. They weigh in at 480lbs for a front axle and 440lbs for a rear axle because there is almost no cast. I finished my disc brake conversion and it will run approx. 5500US for a pair of axles with four wheel discs, they will fit a 16" rim. These discs stop incredible, 14" rotors and 4 piston racing calipers will kick ass over any 1 ton brake setup around, no problem stopping 44's.
They have a few drawbacks like the length of pinion and only 3.5" of offset on the diffs. These problems can be taken care of though, especially if you are building a rig around them. Plus 6.25" more clearence then Dana 60's!!!

Here are few stats for those of you that don't already know the stats on them.

69" from wms to wms
Selectable locker
3.545 to 1 ring and pinion ratio
2.13 to 1 portal gear reduction
7.56 to 1 final gear ratio
Axle shaft necks down to 35mm 1.377" at smallest point Steering CV joint. Each of the two joints compares to a 1480 series u joint
Permanent front axle load (Maximum) 2,500 kg (5511pounds)
Approximately 5" of drop from Portal unit
pinion offset 3.5" to driver side
18.5" from axle centerline to end of pinion
6.25" more clearence than a standard Dana 60

Rear:

69" from wms to wms
Selectable locker
3.545 to 1 ring and pinion ratio
2.13 to 1 portal gear reduction
7.56 to 1 final gear ratio
Axle shaft necks down to 35mm 1.377" at smallest point
Steering CV joint that compares to a 1480 series u joint
Permanent rear axle load (Maximum) 2,500 kg (5511pounds)
Approximately 5" of drop from Portal unit
pinion offset 3.5" to passenger side
18.5" from axle centerline to end of pinion
6.25" more clearence than a standard Dana 60

I think Mog axles are sweet! I have a fwe questions about them and yours. 1)Are the ones your selling from the 404 or the 416? 2) If they are 404 axles what do you think about the idea that the weak spot in 404 axles is the portal gear housing. The design allows deflection between the drive gear and wheel gear. The deflection allows binding, that with a good enough shock load will blow the portal housing apart. When this happens the wheel, brake, and parts of the housing go seperate ways with the vehicle. 3) Isnt there a option for gears that are higher than 7.56:1? I want to run 38's and think that is too low to drive on the highway, esp/ with a RJ 350 pushing it.
