JunFac 90032 Hardened Universal Shaft (95-130mm) 5mm Hole

Seem like good quality. Comes with instructions, a tube of black grease, extra set screws for the yokes, and an extra snap ring. You need/should already have a medium (blue) threadlocking compound, if not, order some while you're here. Tip: clean inner and outer threads first (i use shop towel and qtip), and allow threadlock to set overnight. Only ran them about an hour so far on a Trail Finder 2. No issues. Note: if you are planning to fit these to a tf2, i had to grind down the transmission output shafts and diff input shafts about 1mm each to make these fit. This was on a Marlin RTR. YMMV. Otherwise they fit perfectly lengthwise, etc front and rear. They sell a kit specifically for a tf2, but im cheap so i got these instead and saved a few bucks. After breaking a stock driveline, i feel much more confident taking the truck into remote places with the junfacs.

Used on my trailfinder2. Awsome drive shaft. Fits the truck perfect.

Excellent I bought 2 of these for my RC4WD Trail Finder 2 and they are a lot better than the junk stock plastic ones it comes with

Just got this and it appeared pretty beefy. Ran it out to the rockpile in the backyard and burned up a a battery with a 45 turn motor in a 7 pound leaf sprung crawler. The pile has lots of ledges and ranges from 45° to 60° J Concepts 1.9 Scorpio stuck like glue on the 45° farenheit rocks, had some good fun. Was showing it off later to the neighbor and had to leave. I got back and the rest of the neighbors had their toys out so I grabbed mine and the cup split where the pin goes through on the way down two steps.

Fits the trailfinder2 perfectly before and after rotating transfer case.
