A YJ with an LS, 40's, Coilovers, & Spidertrax Axles

[Fouledplugs]

Why a prorock over rockjock? Fusion 4x4 does fab housing also I noticed. Might be a bit cheaper than spider

Cheaper it may be, the spidertrax has the smallest footprint. Honestly, I am wide open right now as far as front axle options go.

 

[Fouledplugs]

do they sell assemblies or is it all a la carte?
seems like your 5$ away from planetary axles by the time you set up a pair of these.

Spidertrax will sell you all the parts to build a complete axle or an assembly with ends welded, the rest needs to be fab’d and built in respects to your individual build specs.

There are shops like Miller Motorsports or Jimmy’s 4x4 who could build you a Spidertrax to your full specs.

I was looking at their outer C's would be kind of sweet for hybrid 44 idea I've wanted to do. The only issue looks like brake adapters. They only do the wildwood calipers right? Blaine was saying the wildwoods are not designed to work with a booster.

i kick myself in the ass every day for not lopping the JK C's and building it out with Dana 60 ends and 35 spline inners.

i been peekin at these lately.

Does anyone make a 44 center that accepts 3.5” tubes?

I recently saw one of the Ultra4 guys use dodge brake calipers on the Spidertrax stuff up front, now of course, I cant find it.

Blaine was saying the wildwoods are not designed to work with a booster.

I believe the Wilwoods are built for 1000psi, so you would think a booster would pair with it well.

But there are plenty of folks using manual brakes and hydro with their Wilwoods.

If @mrblaine dropped the knowledge it would be dumb to ignore or doubt. He has more time and knowledge in brakes than anyone out there. That fact, I would never doubt or turn a cheek too.

More later but the average TJ booster is capable of 13-1400 psi and I have measured them as high as 1700.

No but i think and adapter chunk / sleeve would solve that.

 

[someguysjeep]

ya, my tubes are over sleeved diff to C.
i was right there, and didn't pull the trigger.

 

[Fouledplugs]

The only reason I have yet to pull the trigger on a front Spidertrax axle with their ultimate steering inner and outer knuckles is the bearing; it isnt sealed.

Being that I wheel down south, water and mud are precedent. I think I would rather have a sealed bearing, but haven't completely ruled out a full Spidertrax front axle build.

So my options have expanded to say the least.

East Coast Gear Supply builds bare tube high pinion 60’s that use the Dana Ultimate 60 center section and I really like the genuine engineered Dana/Spicer stuff.


The Dana Ultimate 60 uses 3.5” or 4” tubes and utilizes a true 10” gear from the Dana Super 60 that they designed and engineered for the Ford Super Duty.

In 2018 Dana developed and prototyped a 1550 sized kingpin knuckle for their aftermarket 60’s. This year at Easter Jeep Safari 2021, Dana finally released their 1550 (SPL-70) kingpin knuckles for the Ultimate 60 to the masses. But it’s not my cup of tea. (Lacks shear option) I am glad to see another 1550 kingpin offering hit the market.

So my options are:

• Spidertrax 3.5” chromoly bare tube front axle housing with Reid’s Super Kingpin inners and outers. (Supports 40 spline outers that use a massive 2” axle shaft and 05+ Super Duty Unit Bearings.
• Spidertrax 3.5” chromoly bare tube axle with Spidertrax Ultimate inner and outer knuckles with their chromoly gussets and skids.
• ECGS Dana Ultimate 60 center section with 4” bare tubes and Reid Super Kingpin inner and outer knuckles.

Damn that is PURE sexyness... Makes be want to think about a new front axle.

What about a fusion dana 60 did you consider them? What's the price on the Dana builder housing?

They use the same Dana Ultimate 60 center from Dana just like ECGS. I think it’s $100 cheaper if choosing Fusion.

By choosing ECGS, I can pick it up in person and avoid freight charges.

What's the price on the Dana builder housing?

Dana sells their center with pressed in tubes and the builder cuts it down to customer spec.

I’m not sure what it cost from Dana directly as I dont have a Dana sales account.

Ah interesting, when I was talking to the fusion guys they implied it was their casting design, didn't realize it was Dana.

Must....Look....Away......

Every time I look at this thread I feel like a bug drawn to the zapper. I shouldn't go, but it's sooooo beautiful!

 

[Fouledplugs]

I’m 99% confident it’s Dana’s Ultimate 60 center.

ECGS does it the same way, another example is their, “light weight front brake kit.” In all actuality, it’s a Branik Motorsports brake caliper hat and and rotor paired with a Wilwood caliper.

 

[Fouledplugs]

What's the price on the Dana builder housing?

Dana Part # 10034535
Front Ultimate Dana 60 Builder Housing
(Buyer/Builder cuts the tubes down to their own spec)

• Bare 3.5” tubes pressed into a Ultimate Center Section - $2,300

That price was given to me from Clemson 4WD who is an authorized Dana/Spicer dealer.

There is one in the works being built in their Lugoff, South Carolina manufacturing plant. Oddly enough, I currently live about 10 mins from that plant.

A buyer cannot buy directly from Dana, even trying to call their customer support line requires a dealer ID.

Thanks, that fusion bare housing is listed at $1300 for a Dana 60 builder housing (3.5"), i got a Carbon/Currie quote for JK44 housing for $1600 with no C's. I'm still trying to figure out my long-term plan (3") leaning toward 44 center section with the 60 outers.

 

[B00mb00m]

i kind of lost confidence in Dana casting design with my Ultimate 44. Turns out they recalled the housing due to the pinion doesn't get very much lubrication and their fix is literally have the installer squirt oil on the pinion bearing with a tube.

that super 60 housing is $995, what is different ? you could finish those 3.5" tubes any way you wanted.
