Peterbilt 6x6 Medium Hauler

I'm surprised no one has told you to buy a 6 tooth pinion from rc4wd? I have them on both my kings and a 55turn integy and have no problem pulling trailers off road. Also on the axle get a set of spider gears and add one between the ones in the difference, that will lock the axle for full traction. A lot of us on here do that also with zero issues

No, sir! Not even close, if I'm honest. The track width is narrower, but certainly not "narrow". It's still quite a bit wider than I'd prefer, but I think this is the best I'll be able to do.

You mean as opposed to the stock 10t? I haven't looked into regearing because I think the 2.6:1 with my Axial transfer case will be low enough. I can always look into regearing later, if need be.


Got a bit more work done. I removed all unwanted tabs from the axles to clean them up and also gain a bit more uptravel (in the rear axles). I also noticed the rear shocks were limiting downtravel so they're gone. Fronts were removed some time back. In addition, I drilled through the front TLT axle and secured it with some long screws.


On the bottom side I sacrificed a stock Hi-Lift spring to provide a bit more strength. It feels VERY secure now! You can also see some of the rough clean-up work I did on the axle. And yes, I know the hardware doesn't match. I need more panhead hardware in the correct length.

Sadly, this is max steering lock. It's currently limited by the stock dog bones/drive cups. I may modify them for a bit more angle or I may look into some CVDs and aluminum knuckles.

In my quest for a narrower front track width, I picked up some Hercules Hobby wide wheels for the front. Aesthetically, I like them, but I think I prefer the Lesu wheels a bit more. Here's some pics.


One interesting thing to note is that with the Lesu wheels, all 10 screws need to be removed in order to access the wheel nut. On the HH wheels, you unscrew that black center section to reveal the wheel nut. Much easier, yes, but it doesn't look as clean to me. And no, the outer cover from the Lesu wheels won't fit the HH wheels.


The backsides.


Side by side. Same width, but the backspacing is different.


Here's where the rubber meets the road. Get it?? Road? Tires?? I kill me... Anyway, here's the offset with the modified Lesu wheels. A little less than half of the tire sits outside the fenders.


And here's the HH side. They tuck in quite a bit more and I really like it!


The slots in the wheels are more of a kidney bean and the Lesu rears are more of a circle, but it's hardly noticeable so I think I'll be sticking with the HH wheels for the front of this truck.

Smugmug is having issues right now so I can't link, but hopefully attaching the photo will work instead....

I couldn't use standard ol' socket head cap screws on these wheels in such a prominent location! Locked Up RC scale hardware to the rescue!
