73 K20....crossmember time

I'd highly recommend it :D







The big 34 spline mainshaft is a beef piece for sure. Can't wait to get it installed the blazer. I have to workout a weird cable shifter issue right now cause I went with JB Fab cable shifters and he has never really made one for the titan before...but once I figure that out I'll stab mine in the truck

Damn that is nice!

Did you buy the 205 kit from them? The one with the fancy aluminum bearing container and what not.

The 34 spline is the input from the trans? I have the 32 spline 465...

No, I didn't get their rear bearing retainer/support. The rear output of my 205 is stock 32 spline just with an ORD flange on the rear. The front output is an ORD 32 spline upgrade with one of their flanges on it too (my 205 was originally a 10 spline front output, so decided to upgrade that now while I was doing everything). I'm going to make my own mount for the rear that supports the rear output and works with my current cross-member I built and already is in the truck. You tell NWF what trans you are going to put it behind and he makes the "input" for the titan box to match (you can see it sticking out in the first pic I posted). Mine is going behind my 700r4 so that is 27 spline. The 34 spline mainshaft actually replaces the whole input of the 205. This is what makes the Titan box stronger than the eco/black box. It's the fact that there is no "intermediate" shaft to connect the black box output to the 205 input. In the titan box, its all one unit (very similar to ORD's magnum box). So you replace the entire input of the 205 with their 34 spline unit, and then the back half of the titan box bolts onto the front of the 205. Then you bolt the front half of the Titan box to itself (it splits in two...I've actually heard that the front half of a normal black box and the Titan box are identical, its the rear half where the difference is).

So the only thing in my entire driveline that will not be 32 spline or larger will be the output of my trans which is 27 spline...but luckily I have a tired bone stock TBI350 not putting out much power, and I don't beat on my rig too hard for no reason, so I'm not too worried about it. My brother has a healthy TBI383 with a 700r4, doubler, rockwells, and 47's and his tranny has held up just fine...he's even broke Rockwell shafts before his tranny output let go...so I think it will be good! :)

Ok interesting. Good info. I'm wondering if it's worth the 250 bucks. One of those might as wells.

I'll have to call. I don't want to be snapping trans outputs but I guess I'd be up shit creek either way lol.

I saw on the Instagram that the rock bouncer guys are running the same set up as you. If they can deal with a 496 flying through the air and landing at rev limit on 54s , I'm game lol.
 
How many guys are breaking 32 splines? I would imagine it would take a lot of skinny pedal, horsepower and traction.

To be honest I've never seen someone even kill a 10 spline. I've seen worn couplers of course.

I may be better off dropping that cash on their 205 rebuild with bling bling parts.

Whats the specs (input/front output and pattern) on your current 205 case?
 
Yep the splines on the 10s are the weak link. Stripped a few sets myself

Like skunk said, bore it and but a 32 spline input. To go behind the 241 planetary of course
 
Ah, so you just need to bore the case to accept the big bearing 32 input.

Yeah that's what I'm thinking. I just started stripping it down. I'll use the titan shaft with the black box so no input shaft needed since it's all in one.
 
It's 10 spline in and both outputs are 32 spline

Did you already upgrade/replace the front output on your 205? Cause as far as I know, there were only 2 ouputs offered in all GM205's, either a 10 spline or a 30 spline (and which one depends on the year of your tcase...later year 205's got the 30 spline versions). As far as I know, the only way to get a 32 spline front output is to swap it out with an aftermarket version...but I guess I could be wrong and someone could let us know.

Yeah, my case was originally a 27 spline input (pretty much the same size bearing input as the 10 splines as far as I know; and I bought it cause it was cheap, guys want a lot of money for a 32 spline input version, so it's almost easier if going this route nowadays to buy a 10/27 spline version and just plan on boring it out), so I had to have my case bored out to accept the larger bearing. The Titan case supplies you with, of course, the new 34 spline input, but also the required new bearing too. From what Kris at NWF told me, its the same bearing as a 32 spline input version 205

To be honest, this thing is probably way overkill for my uses...I'm not a rock bouncer hitting things crazy hard. Sure I have 44's (and actually stepping down to 42's right now anyways), but I have been rocking my SYE NP241 for a couple years now and have never thought twice about it holding up just fine. I really just wanted/needed better gearing with the tire sizes I'm running. I looking at re-gearing my axles, I looked at Atlas 2's, I looked at it all. And to be honest, for my current situation, and for the money, this was the best route for me to get everything I needed. I will have an actual true 4 speed t case (more gear options than Atlas 2, better overall than just axle re-gear, etc...), and this thing is within an inch total length of my 241 SYE...which means I don't have to do driveshaft mods, I can keep my cross-member/skidplate that I build a while ago, and have to change minimal things to get this thing in there. So though I spend just a little more in price over a normal black box/eco box, it saves me money/headache later on by having to change lots of stuff to get it to work....plus, like I said, it's pure beef and I'll never have to worry about it in my truck, haha

And like @skunked said...the last thing I would be worried about is a 32 spline output of a 465...if you break that you were doing something really stupid!

Ah yeah I forgot it is 30 spline on the front because it will take the same yoke/flange as a np208.

So I need to bore the case for the bigger bearing and add the 32 spline front output from ord.

Yeah, that makes more sense now...and you are correct, 30 spline front outputs had the flange on it where as the 10 splines had the yoke (per say).

To be honest, you could probably keep your 30 spline front output and it will work just fine. Even on ORD's website, they talk about the 10 vs 30 spline front outputs and they even say the 30 splines usually holds up just fine...it's more the 10 splines where people saw the most issues when abusing them. And the front output can be changed later on if you really want/need to with the tcase still in the truck. Like I said, really the only reason why I upgraded mine was because mine was a 10 spline front output. If mine had been a 30 spline I would have just left it alone until if/when it broke.

just food for thought is all I guess
 
Just ordered a bun ch of box tube and angle iron for the crossmember. Going to leave the trans one alone for the moment since it's just fine. I may need to modify it eventually but I'll probably just make a new one and attach it to the tcase one.

I know I'll have front driveshaft interference but she'll be 2wd for a while before I can afford a front driveshaft lol.
