2012 GMC Sierra 2500 HD Serpentine and V Belts

Yukon Gear & Axle offers a full line of top quality differential tools to save time and money.

Constructed with aramid reinforced EPDM compounds, the Dayco poly-V serpentine belt delivers  more than just OE quality. Developed through extensive laboratory and road testing, the rib profile in this EPDM belt has been engineered to conform to high mileage, worn or misaligned drives and helps eliminate noisy belt conditions. Dayco poly rib serpentine belts offer extensive flexibility and longer service life, while handling higher workloads and temperatures.

Dayco ela (elastic) or stretch belts are specifically designed for two, three, and four point drives that are designed to use self-tensioning belts. Although these belts may look like standard poly rib belts, they are very different. These specially designed elastic belts have self-tensioning capabilities required by specific OE drives. Vehicles that are manufactured with stretch belts must replace them with stretch belts. These belts are not interchangeable with standard constructed belts of their same size. Dayco ela belts utilize a proprietary EPDM construction that is designed to elongate over the fixed pulley system, and then maintain the required belt tension over the life of the belt. The backbone behind the Dayco ela belt is its specially developed polyamide tensile member, which allows for high elongation required for installation, yet provides the proper tension maintenance properties to transmit the accessory loads demanded for the drive. This belt construction incorporates a wear resistant EPDM rib material, along with a highly elastic EPDM cushion rubber that surrounds the polyamide tensile cord, thus providing the required adhesion and flexibility to maintain lasting performance. Stretch belts have unique installation instructions depending on the OE application. Installation may require a specialized tool for the application or a simple zip tie. Do not attempt to install by prying the belt on the pulleys. Dayco provides detailed instructions on the reverse side of the sleeve.

The Driveworks belt is designed to provide better belt-to-pulley contact. The specialized rubber compound incorporates a high temperature polymer formulated to maximize load carrying requirements and belt life. This Driveworks ribbed belt has been constructed and engineered to meet the stringent demands of today’s automotive drive systems. The Driveworks ribbed belt delivers long-lasting dependable belt life.

Gates Fleet Runner Micro-V Belts are designed for the toughest applications. Fleet Runner construction provides superior flexibility, stability, load capacity, and unsurpassed belt life. Patented materials deliver peak performance at extreme prolonged operating temperatures, making this belt the ultimate problem solver. An advanced blend of EPDM rubber technology withstands the modern threats of deterioration from increased exposure to ozone and water-based coolants. Fleet Runner does this all while providing the lowest cost per mile for fleets, including 3/4 and 1 ton pickups.

Stretch Fit Drive Systems Demand Highly Engineered Solutions.

Carquest Standard serpentine belts are constructed from quality materials to ensure durability and a long lifespan. We design and manufacture each Carquest Standard belt to enhance belt-to-pulley contact, maximizing load-carrying capacity and extending belt life. Our serpentine belts are built with EPDM rubber and treated polyester cord to improve durability and belt life. Carquest Standard belts are the right choice when looking for OE fit, form, and function at a great price.

Dayco idler/tensioner pulleys are built with smoother surfaces and tighter dimensional tolerances, which translates to less vibration and longer belt life. In addition to stamped, forged steel and powdered metal pulleys, Dayco also designs ultra-strong plastic pulleys with specially formulated glass-filled polymers that resist wear and tear. Premium lubricated ball bearings and double high temperature seals ensure peak bearing performance, the most critical element of a pulley’s service life.
