After helping a buddy with some issues on his '92 6.9 project, I traded him my dually hubs, 3" rear wheel spacers and my god-awful flat-spotted 37" military MT's on HMMWV 12 bolts for his standard hubs and 285/75r16 BFG AT/KO's on MB Razor 16x8's. Today on the way to work, heard a CLANK and then SCREECH SCREECH SCREECH. Pulled off in the Napa Auto parking lot to find the caliper retainer/lower slide had SHEARED OFF and allowed my passenger side caliper to brawl with my new wheels. Popped in and grabbed a brake hardware kit, thanks to the backspacing of the new wheels I was able to stab in new retainers on both sides in ten minutes. Got to work, was then sent down to the local machine/metal shop for a healthy stack of 4'x8'x1/4" AR400 steel. Hauled donkeys back to the shop, thoroughly enjoying the power gained from smaller tires. Heading home after work, I pulled the grade between Placerville and Camino at 65 in 4th with little effort, where I was only able to pull 55-60 screamin up the hill in 3rd with the 37's. 3.55's, 37's and N/A don't play well together. I do believe some 315/80's are in order when the 285's wear out. All in all it was a good day, crisis averted, carry on.
