It comes with a protective coating to prevent corrosion and ensure a long service life. This pinion gear is also backed by a warranty from General Motors, providing peace of mind to vehicle owners.

It is made from high-strength steel, with precisely cut teeth and a hardened surface treatment to ensure durability and efficiency. Proper installation by a certified mechanic is essential to ensure optimal performance and reliability.
