My NORRA Pioneer build

where'd the Alcan springs come from? direct?

Yes called them and customized for my estimated weight and function.

mmmm torque

Very Cool!!! Just wondering about that rear pinion guard could it cause issues "scooping" up dirt and rocks in deep sand/silt?? A friend up here in the Black Hills has been running a vintage Jeep in a few Score races and had some issues with rocks getting picked up in the chassis, Maybe Todd Z or Andrew can chime in.

Any numbers on that new Mill?
The rock guard? I was wondering about that too.

I ran a pinion guard for years on my 96 Bronco. The guard had openings to let out water or light sand. In all the years I never found anything trapped inside the guard That guard was bolted to the third member of a Tubeworks axle. That truck is long gone and I forget who I bought it from. I wonder if it was Raceworks? I don't know if they still sell that thing. ChrisW has a no name version of the same thing on the race Bronco and he has never had anything inside to clean out.

RuffStuff 9" pinion guard $60.

I expect the pinion guard to be fine, there are plenty of holes in it to let whatever out.

Two schools of thought on the guards. One is to protect the pinion - like the one posted here. And the other is to function as a skidplate under the 3rd member, like the Stewarts Raceworks or Autofab pieces.

Here's the Autofab version:

Paul - I'm guessing ChrisW has one of these two versions.

We have some Stroppe-esque reinforcements on the underside of our rear housing. It's remarkable that ours has survived intact considering how many rocks we go through in Baja.

That reminded me, the 9" I am using has been shaved and 1/2" plate has been added to the bottom side and back of the lower housing along with the DOM brace on the back. If it didn't have that plate i would have went with a skid plate.

A Colorado Classic Bronco member upgraded his rear suspension and was gracious enough to let me purchase this one from him for a great price.

As a side note... I have been weighing some stuff as i remember along the way - the original bare housing with all of the previous owners four link stuff welded on was 83lbs, i cut off what i didn't need and the bare housing I am using weighs right at 50lbs. I forgot to weigh the finished axle but it has to come out one more time to set the pinion angle and weld the perches and when it does i will weigh the whole thing. My guess is it will be close to 180lbs.

I forgot to post the video of the last dyno run yesterday..

Front end is rebuilt and re-geared and then slid it under the frame. Welded the front and rear lower shock mounts, started running fuel, brake and transmission cooling lines.

I think the springs are gonna hit the cross brace of the shackle. Flip the shackle around, should be fine.

Yup, they’re on backwards.

Ha you know what I wrote down the direction and still got it wrong. “Cross brace back”

Thanks for the eyeball, will switch em this weekend.

Todd, I misspoke both Broncos had the Stewert Raceworks skid and the Pinion guard like the one pictured, but don't remember the supplier of the pinion guard. No criticism of either after very long usage in Baja.

While I have the body off the frame iam running fuel and transmission hard line on top of the frame rails to keep them out of harms way and out of the exhaust heat. I only had enough hard stainless steel line to run one length for the main fuel supply from the rear cross member. I had 25' of aluminum hard line on hand and used that for a return line for fuel (future EFI and redundancy) and ran two lines to the rear of the frame for the transmission cooler. The aluminum line is of course much more fragile than the steel line. I have been rethinking it's use and just wanted to see what everyones opinion was on using aluminum vs steel/stainless steel. My budget is tight and was trying to use what i had on hand but now thinking twice about it since i have access.

 

[Apogee]

I plan on running NiCopp lines on my rig when I redo them, for both fuel and brake lines. I like how ductile it is and less prone to fatigue when compared to stainless, but it still has comparable corrosion resistance and is easier to work with. That said, as much as I don't think you'd ever have an issue with aluminum lines where you've routed them, short of somebody spearing them with a screw driver or something trying to un-wedge a cactus from the undercarriage, I would probably go steel, SS or NiCopp on the fuel return lines for peace of mind.

 

[markw]

We have AL lines run on the top of the frame like yours. I feel pretty comfortable they are out of harms way there. Braided lines where they need flexibility on each end. I think if they lines are breached where they are we have bigger problems than a fuel leak. Mark

Excellent. I will run em then, thanks for the feedback

 

[landshark99]

More stuff on the frame, engine home, viper built transmission and transfer case in temporarily.

What gear ratio did you go with in the axles?
