Rockwell Upper Link Brackets Short / Front

This premium builder kit consists of four (4) 3/8” thick riser plates, two (2) 3/8” thick inner gusset plates & four (4) 1/4” thick CNC formed steel outer gusset plates.  The vertical separation between the lower link pivots (Kit # MB2124 sold separately) & this front upper link plate kit is 9” vertically.  The axis of the upper pivot is on center with the axle & is positioned 7” vertically from the topside of the axle.  Inside dimension of the riser plates measures 2-5/8” with holes to fit 3/4” diameter bolts.  The riser plates are designed to straddle three sides of the axle so you can get the most amount of weld for strength. The inner gusset plates feature keyed slots for interlock positioning with the riser plates.  We could have stopped right there & this would be one of the strongest Rockwell upper link mounts available, however, we took it one step further.  We then completely boxed in the risers & inner gussets with precision CNC formed outer gussets.
