About this product

GM Genuine Parts Engine Balance Shafts are designed, engineered, and tested to rigorous standards, and are backed by General Motors. In every reciprocating engine, inertial forces and moments of inertia develop due to the oscillating motion of the pistons, connecting rods, and the transmission behavior of the crankshaft drive. Balance shafts are weighted shafts used to offset these vibrations of the moving and unbalanced internal components of an engine. 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).
