The Balmar Belt Buddy with Universal Adjustment Arm gives a complete belt tensioning system for an alternator. It combines the Belt Buddy mechanism with the arm it mounts to in one purchase.
This full set is part number UBB, distinct from ordering the arm alone (UAA) or the mechanism alone (BB or BBU for use with an existing arm). It’s worth confirming which configuration the install actually needs before ordering.
Together, the mechanism and arm make it noticeably easier to set and maintain proper belt tension on an alternator install. There’s no need to fight a stiff factory bracket by hand. Shop more marine alternators.
