Yeah, the HD ones. I tried to install them once, but the nut for the upper shackle bolt inside the frame rail lost its welds at some point, so I can't install them until I yank the whole rear bumper off or cut into the rail from above. I'm leaning towards cutting, given the number of bolts that are in that bumper.
I probably won't go up to 35's until my 33's are completely worn out, but they still have a ton of life even after almost two years of being daily driven and punished on the trails. Then again I could probably sell them for at least half the cost of a set of 35's. I'd like to get the shafts done and do a disc brake conversion on the 8.25 first anyway.
