SOLID Front Axle Hub Conversion Kit - Available & Installed!!
I do have some questions as to any track width increase (scrub radius definitely has an affect on both handling, the effect of power steering in the rocks, and both ball joint/wheel bearing wear)?? I tried to call Matt back before I deployed to ask those questions, hard man to get ahold of. I also am wondering if it doesnt increase the track width, if anyone knows if there is enough material to simply redrill the stock rear axle flange???
Lastly, the rotors come with the kit, can they be "made" later when a brake job is neccessary?? (Lets assume it is either not cost effective to mail order rotors from solid, or prior planning did not come into play).
I'm just talking here. I dont know the answer, . Its definetly something to look into if you wanna save some cash, and like your wheels
Got yeah. sorry about that. I would call them and see. I'm no engineer. I'm sure you get get your center hole reemed out. But how weak would that make your wheel?

I'm confused as well....
There's several people here who aren't sure of what the benefits are? What does this do for you?
You said you have to get out and manually lock them? What's different from the lockers we already have? Then another guy said you still need your lockers and this is two different things????
Can someone please give a "solid axles for dummies" explanation?

Ok lots of questions and I will try my best to answer what I know .
Stock jeep has non servicable unit bearings that are alyways "locked in"
The benifit to this set up =
-Strength- a spindle and hub which this is. Is so much stonger than a unit bearing.
-The ability to not have your front end spinning while driving thus reducing the "drag". MPG increase will be very very slight if at all. Normal wear and tear will go down.
- The ability to unlock a hub if one of your axles break.
- The ability to flat tow without putting miles on everything , I believe they are working on a rear end full float kit also.
- A Hub kit acts as a switch so that your axles do not "engage" at the wheel. No engagement meens no turning , means less wear.
If you brake a front axle shaft on the trail with your stock set up you have no choice but to get out and fix it . With this set up you can simply unlock the hub and limp out.
Also I believe the center bore of your new wheels need to be 4.250" I know the wheels for the JK are limited going to 5 on 5.5" will open up alot of new wheel designs and MFG's 5 on 5.5 has been around forever.
Also you can run CTM u-joints on a daily driven vehicle there is no problems with that we have been testing one set for over 50,000 miles now without any trouble.
Con to this set up-
Price- Lets face it it is alot of money
New wheels- If you are planning on doing this set up you may want to do it when you first lift your jeep so you dont have to buy new wheels twice.
Unlike the TJ the JK allows us to run a much bigger tire than what the stock unit bearing can handle for a long period of time. My guess is if you are on 37's your stock unit bearing will last maybe a year or two at the max. and unit bearing are not cheaper either they go for around $125-$175 each
Well that is my 2 cents hope I was able to help you out.

Lock-out hubs allow you to unlock the front drive train at the wheels. Older 4x4's all had them. Most modern 4wd systems do not have any provision allowing you to unlock the hubs which means the front axle and driveshaft are always turning. The primary advantage of being able to unlock the front hubs is to reduce wear to the front half of your drive train. It's also nice on lifted vehicles because the increased angles of the driveshafts often cause vibration. If your front shaft isn't turning it can't be vibrating.
Hope this helps.
been hoping for this,if avail for 44 sign me up(I love owning a JK,new toys and adds coming out everyday,UPS and the credit card companies must love us.read a good quote recently"you already shot yourself in the foot when you asked salesman how much for the Rubicon? so you might as well go all out and do it right"
You know I think this is a pretty good idea for a JK. MPG will certainly go up, how much is unknown, but I guarentee it will, as those axle/driveshaft/tcase input parts will not turn anymore, resulting in both a whole lot less driveline drag AND wear (4 wheeling causes sudden breakage, not longtime wear, and Ill bet it will add to the longeevity of ujoints/driveshafts and axle seals as well). I have 3 guys at home in Maine off the base waiting for this, 2 just because I touted certain gas mileage increase (small side Jeep business Ive got). I do have some questions as to any track width increase (scrub radius definitely has an affect on both handling, the effect of power steering in the rocks, and both ball joint/wheel bearing wear)?? I tried to call Matt back before I deployed to ask those questions, hard man to get ahold of. I also am wondering if it doesnt increase the track width, if anyone knows if there is enough material to simply redrill the stock rear axle flange??? (if there is additional width, can matching width spacers with the appropriate wheel pattern be found??) Lastly, the rotors come with the kit, can they be "made" later when a brake job is neccessary?? (Lets assume it is either not cost effective to mail order rotors from solid, or prior planning did not come into play).
The stock Rubi front axle wouldnt be bad at all, if someone could come up with some cost effective trussing for the weak tubes, and some weld on bracing for the inner "C"s. Think of it, 30 spline chromoly outers, the better Rubi ujoints (hopefully some aftermarket ones will be available soon, especially with this, they wont turn on the street anymore, so you could go with a bushing, CTM style, instead of needle bearings) some stout 33-35 spline inners, and a matching Detroit/ARB/OX.............just some food for thought. I certainly wouldnt want to do it all at once, if I did that, I would just invest in an aftermarket D60, but to be able to upgrade when stuff breaks!!

Let me know what time is good to call you. I know you are busy with your duties to our country, but didn't want to write an email.
The distance between the wheel mounting surface and the knuckle is unchanged. When the kit was designed I had a few parameters had to be met.
1) Retain the ESP functions using the factory sensor and have the sensor in a sealed environment.
The sensor mount is machined into the spindle and the reluctor ring is machined into the hub. I could have simply welded a block onto a spindle and a press on ring, but that's a very cheesy way to do it. I'm not saying it doesn't work, but I wouldn't of been happy with that cobbled arrangement.
2) Utilize a readily available shaft length / lockout configuration.
I chose the 9.94 long Dana 44 stub shaft.) The main reason that if a stub shaft does break, many individuals will have a spare lockout and shaft. I didn't want to see a weekend ruined from a failed special shaft. Our shafts are US made by a very well known forging house and are 30 spline.
3) Use a readily available rotor.
I chose the CJ style rotor and bore out the center to 4.00 inches. I could have used the rotor as an off the shelf product, but wanted to ensure a positive stop for the reluctor ring sealing. Since there is machining involved, they are provided. There is no machining on the OD of the rotor.
4) Upgrade to the 5 on 5.5 bolt pattern.
I did a bit of research on the 5 inch bolt pattern and decided that I wasn't comfortable having people bore out their wheels. The aftermarket offers 5 on 5.5 wheels in many configurations and styles. People that have purchased wheels can still sell them for reasonable value to other JK owners that do not want this upgrade.
Included in the kit.
2 forged spindles with inner spindle bearings installed
2 forged hubs with races installed, seals installed and the back bearings greased
2 30 spline shafts
2 v-lip seals, thrust washers, mud slingers for shafts
2 u-joints
1 Warn 30 spline lockout kit
2 spindle nut assemblies
2 rotors assembled onto hubs with studs
2 front bearings
I realize this kit is not made for everyone and didn't design it for everyone. It was designed to fill a void in the market where people need CTM u-joints, and aftermarket shafts as well as the ability to disconnect the front drivetrain.
BTW a true high pinion 60 front end retaining all ESP functions is right around the corner.
Matt
