Anyone use this Axle for lifted applications?

[808ram1500]

So I replaced my OEM axle on the passenger side due to a ripped boot (100k miles) with a Napa brand. I have a 6" lift btw. I swear I drove maybe 200 miles with the Napa brand axel and off roaded once on a pretty rocky terrain. The Napa boot is leaking on the wheel end so I'm assuming the boot is torn. I know Napa warranties their junk so I'll probably get a warranted one in the mean time. I also found another axle on rockauto.com made for lifted applications with high articulation. Does anyone here have or experienced using these? For the price of a Napa axel I might try them?

how much is your differential dropped and what kind of lift are you running? From what I've read these boots only fail when there's an excessive amount of flexing to accommodate lifted geometry.

RC 6 inch. Had it for 3-4 years. Oem boot ripped, replaced with Napa brand and the boot is soft compared to oem. It ripped when I offroaded. Lifetime warranty so I got a free replacement. I just recieved the track motive axle and the boot quality is hard like oem. Did some research and looks like the differential side is the week link due to the oversized bearing used. They tend to heat up and there is insufficient grease to lube it. I haven't installed as I already put on the warranted napa one. When that leaks again I'll use the track motive one.
