GM Genuine Parts Engine Balance Shaft Chain Tensioners are designed, engineered, and tested to rigorous standards, and are backed by General Motors. This tensioner keeps the proper tension on the chain or belt that drives the balance shafts to prevent slipping or jumping on the drive gears during rotation . This helps prevent excessive engine vibration and keeps all gears and shafts operating in sync. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
