The SPC heavy-duty support plate spreads load from 3" axle spacers and Z-blocks to prevent pressure points that can crush caster wedges on heavy-duty suspensions. The 1/8"-thick plates come six per pack, support 3"-wide spacers, and can also be used to help dial in ride height side-to-side. They’re intended for use with commercial and medium-duty axle spacer setups where load distribution matters.
