Man, I haven't been on here in awhile. I did a quick search with no luck. Anyone out there have an opinion on a really strong front driveaxle replacement? I keep snapping mine in high RPM/torque situations. I did it again yesterday trying to pull my dad's dead backhoe back to the shop.
Now, I fully know this is happening because of my lift kit. At the time I went with what I felt was the best choice for me. It's from Cognito Motorsports. It's the non-T-bar drop 4-6 inch kit. Originally set at 4 inches, I never had any problems. They even say at 4 inches, all geometry is the same based on their desiing (it drops the front diff 4 inches apparently). They too say at 6 inches the drive angles will be slightly off, but should work fine. It does use spacers regardless for the front axles.
Recently, I used a new alignment guy when I put the new tires on it, and he simply couldn't get the camber right. I called Cognito and they recommended their aftermarket (longer) upper A-arms to help with that. It did the trick, but made it a 6 inch lift, so I added the appropriate rear blocks. Now I've broken 3 axles in as many years. Granted, the NAPA Remans I'm putting in there are probably part of the issue. I think I want to try what will be an interim stronger axle at least. Any suggestions? I'll reach out to Cognito again as well.
Eventually, I intend to upgrade the whole front end. Probably keep it IFS, but do a locker, stronger cross shaft and tougher driveaxles. I read an article about all of it, but can't find it right now. But they used these (WARNING: this is insane):

I digress. Short version :What's the best, toughest aftermarket front driveaxle for my truck? Or do you know of a longer axle for lifted trucks?
Thanks!
