If you're making your own pedal box this is the balance bar to choose.
Industry standard 7/16" UNF threaded, hardened bar with 5/16" UNF anodised clevises.
Phosphor bronze spherical bearing.
Complete with reamed bearing tube (31.9mm OD, 26.2mm ID, 35mm long) to weld into your own pedal.
We know these aren't the cheapest around but they are by far the nicest we've seen.
