Alternator Bracket: A precisely engineered SBC alternator bracket is included to securely mount your alternator to the engine. This ensures correct belt alignment and appropriate tension, which is critical for efficient battery charging and overall electrical system health. This Small Block GM alternator mount is a key component for the stability of your charging system.
V-Belts: The kit comes complete with the necessary V-belts, typically two or more depending on the accessory configuration, pre-sized to perfectly match the included pulleys and your specific Small Block application. These automotive V-belts are engineered for reliable power transfer to the water pump, alternator, and any other driven accessories, such as power steering or air conditioning if applicable.
Mounting Hardware: All essential mounting hardware, including bolts, washers, and spacers, is provided to facilitate a straightforward and secure installation of every component. This ensures a proper fit and finish for your Small Block Chevy accessory drive system.
