Locking Plates For Tuf-Country Dropped Axle Pivot Brackets

Shown above in most-positive camber position. Clicking on the picture will get you a large, but somewhat blurry version. (It was dark out, I took picture with flash, but viewfinder didn't work)

Tuf-Country, a manufacturer of lift kits also sells their dropped axle pivot brackets alone. (without a lift.

These greatly simplify camber adjustment, but I was not happy with the way the cams worked. The fit was overly sloppy (to my mind anyway) and because a flat had been milled the length of the pivot bolts, I was not able to tighten them enough to prevent slippage without stripping the nuts.

Shown above is my re-engineering to provide positive, slip-free adjustment. I freely admit that my approach complicates adjustment. Only 8 individual settings are available vs. the continuous range of adjustment provided by Tuf-country. This is, however, adequate to set camber to within better than1/4 degree. 1/4 degree increments is what traditional camber adjustment bushings for TTB alignment bushings provide. I consider the fact that these CAN'T slip to be an excellent trade-off.

I made these of 304 stainless, to preclude corrosion. If you don't worry about that, then mild steel should serve the purpose just as well. If you are rich, knock yourself out and make them of Titanium. The grade-8 axle pivot bolts really need to be torqued, so aluminum is probably too soft for this part. In some positions, the bolt heads will be very close to the stops on the brackets, so washers aren't a good option.
