VH44 brake booster overhaul kit, this kit is for the 0.750 (3/4") primary bore. These kits are not just an 'off the shelf kit'. There are 2 different control diaphragms, 2 different main diaphragms & 2 different primary bore sizes (3/4" & 5/8).
See VH44-72 for the 0.625 (5/8) primary kit. Call us to order, we really would like an image of your VH44 internals emailed to us to make sure the correct kit is supplied.
