I've put two Cardone boxes in my truck in the last few months and both have started leaking at the output shaft within a month or two of installation. Now I'm back on the hunt for a quality box, I'm willing to spend the money on a top-quality product but from what I've seen PSC, Red Head and Blue Top all have mixed reviews. Has anyone tried the Dmaxstore box, Part# DMAX-SG-0107? (see link below) It currently only has 4 reviews but all 4 are 5 stars. Priced at $589.56 for a new box. It's only a 4 bolt but they provide a QAQC test sheet for each box and it comes with a 3-year warranty as opposed to the 1-year from red and blue. I also still have my original box that I only replaced because the input shaft started leaking. I'm fairly certain it is the original box but it has almost 200K miles on it, I'm also contemplating just replacing the seals in that or sending it off for a rebuild if I can find a reputable shop to do the work. TIA
