Center bearing support with a 4-3/8" bearing and 4-3/8" shaft offset, 11 gauge steel. Does the same job as the 3-3/8" version but with a larger bearing and offset for setups that need more distance between the shaft and the header. Keeps the torsion shaft stable in the center so it doesn't bow during operation. Sold individually. If your bearing is seized up or the bracket's cracked, replace it before it damages the springs. Check your current bearing size, it's stamped on most brackets, and make sure 4-3/8" is the right spec.
