From being a member of many FB groups- the axles have been falling out right and left on Thumper Fab and the other name brands. I went with the SATV for several reasons. One, I haven't seen one report of an axle falling out. Second it was at a good price. I see some say the fully boxed frame of Thumper Fab and others is so much better than SATV. Well the Xpedition isn't my rockcrawler- that's my Turbo R. The Xpedition does go on rocky trails in Colorado and the SATV LT kit will hold up fine. i had SATV arms on my XP Turbo and they held up fine.
Took me about 25-30 hours to install the SATV LT kit, bleed the brakes, do front end alignment and camber. I did order springs from Schmidty yesterday. The SATV 2 seater LT kit comes with springs, the XP5 doesn't.
Forgot to mention I also went with the SATV 300M ball joints. I added grease zerks as I don't care for the needle type grease fittings
