I am a satisfied Weldtec customer. I installed a Baja Grocery Getter in my driveway (6" 2wd Econoline lift.). I did get them to email me a set of detailed install directions, and found that there were some tidbits missing that would have helped. I made notes on my set in case I ever installed another, or to share. They do have videos on Youtube that are a great starting point for installs.
The product quality was really good, the radius arms were impressively made.
The Fox shocks were back ordered and came a few weeks after the rest of the kit, but this was all communicated and handled well. To me it indicates a well run business, I asked them to ship the kit without the shocks and send me the shocks once available....and they did.
I have not put enough mileage on the kit to really speak to the performance and reliability, but I have no reservations about the quality at this point.
Mark me down as a satisfied customer very likely to buy from Weldtec again.
