4007 Series Hyper Coupler (8mm REX™ Bore to 8mm REX™ Bore)

This 8mm REX™ bore Coupler allows you to connect 8mm REX™ shafts together in a compact and balanced form-factor.  And as with all ‘Hyper’ parts, this too is balanced so you can spin it up without concern of creating unwanted vibrations through your drivetrain.
