The Dmax Store is where I'd seen them 1st.
Did some research and it looks like there're manufactured by TrakMotive & rebranded Dmax.

Don't really see a reason to run those unless you are lifted with torsions cranked and lost the spacers that come with the lift?
Not sure over the years where I started for Stock Ride Hight Form. It's Stance is pretty high using 1500 Keys & Torsions & Kryptonite Uppers Control Arms. (Look @ Sig)
I had bought these CV shafts because there designed with a sliding center bar that supposed provides up to 40mm more travel than the OEM GM CV shaft.
Also the CV joint also can bend up to a 47° articulation angle compared to a maximum 23° articulation angle on an OE CV joint, in which I though would benefit the torsion adjustment.
I just sent pair back to ROCKAUTO due to fitment issues, It appears the Incorrect shaft was placed in the Rite Box.
These have a Round Inner Coupler and would not fit in place. I had brought these and my truck to a local GM dealer to have installed and5 hours later, I had the Tech reinstall the old Cv due to them not clearing the front differential output shaft.
I was Quite FN Angry that I hadn't noticed the Difference in the Shaft # VS the Box part # !
I've used them, nothing bad to say about them yet. Biggest issue I've had with the aftermarket CVs of multiple brands is the cheap boots don't last Long in the salt up here or at higher joint angles.
Agreed with you. Ive found world parts cv axles seem to last the longest for me so far.
I've used a couple CVs that have the round inner coupler like that without issue.
Well the GM Tech @ the Dealership couldn't get it in place.
They took apart the Upper Control Arm Balljoint, Shock, Tie Rod end, Caliper & Rotor, and the Swaybar link.
They where going to unload the torsion bars but couldn't locate their Tool.

What's hanging them up? I've swapped stock ones in my driveway with basic hand tools. Something seems off if the dealership can't do it on a lift with all the tools they got unless there is something wrong woth the axle
Sounds like they are too long. I can do mine in my driveway and only need to remove the swaybar end link from the lca. Doesn't even make sense why the rotor and caliper should have to come off since they are on the outside of the spindle/hub.
Me thinks that maybe they are designed for lift kits to eliminate the spacer and still allow the extra travel
Looked on Rockauto, and their "standard" axle specs are:
As compared to the XTT version:

That's how I've done mine. Don't have to remove anything else to get them in or out.
Apologize for the delayed response, took the wife & dog the Beach to watch the Sunset.
The Tech said the round inboard end of the CV shaft was not clearing the front axel output shaft due to it being a solid round instead of the OEM Star shaped CV
See Photos for comparison.
Thank you (TheBac) for posting the Specs.
I compared the Specs before purchasing the CV shafts & as it was pointed out (2mm longer) so I felt confident in using them & liked the idea that they can handle the angles @ 47° articulation.
Just didn't notice the Round inner weeks ago when I received & unboxed them on the tailgate, also didn't notice the different part # on the shaft VS the Box.
Leaving SW Florida in a couple more days & heading back to New England for the Summer, just wanted to get them installed before the 1700mile trip home.
The Old Shaft sprung a pinhole leak and started slinging grease, so I was being proactive before traveling & upgrading in the meantime.
I'll see about getting another set that have the star shape & do the job myself
The only reason I used the Dealer was not having the appropriate tools while traveling. When I get home and back to my Garage I'll get it done.

It’s more than that I’m sure. The whole wrong part number basically seals the deal. Probably wrong taper to fit the output shaft and possible wrong bolt pattern.
I wouldn’t get hung up on the fact is round as I’ve put round ones in these trucks too but there are other issues the tech ran into. Main one being the wrong part number all together.
Get the right one, pop it in, roll on
