These plates allow for 10" to 15" bolt radius from axle center point, 2", 4" and 6" behind centerline.

Slots are sloped ahead at the top to minimize change to static pinion angle when moving pull bar bolt up or down.

Allows for 3/8" increment adjustments on rear end, for both top shock and pull bar bolts.

Comes with two 3/4" to 1/2" reducer bushings for top shock bolt keepers, two top shock bolt keepers, two pull bar bolt keepers, and two 1/4" high strength steel quick change plates (QT100)

The main goal of developing these plates was to make adjustment of the pull bar easier, eliminating the need to pull the pull bar bolt, as well as to reduce the magnitude of the adjustment on the rear end, allowing for more fine-tuning over conventional pull bar plates with bolt holes.
