Litens Automotive is the original equipment supplier for the 2014-2018 Chevrolet Corvette, Silverado, Tahoe, Suburban / GMC Yukon, Sierra with 4.3/5.3/6.2L. This replacement pulley is also designed and produced by Litens and is exact in all form, fit, and performance characteristics as the original equipment part (with the exception of not having the car manufacturer’s logo or part number applied to the part). Decoupling pulleys are engine specific and should never be interchanged with other types of pulley technology. The Litens OAD type pulley is designed to free-wheel in one direction and, with an internal spring and damping device, softly engage in the opposite direction. The OAD is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component as well as the alternator. The correct decoupler pulley ensures smooth, quiet performance as well as increasing vehicle gas mileage. Under normal driving conditions, the original pulley will require replacement in approx. 70,000 – 90,000 miles.

GM Genuine Parts Remanufactured Starter Motors are designed, engineered, and tested to rigorous standards and are backed by General Motors. Remanufacturing starter motors is an industry standard practice that involves disassembly of existing units, and replacing components that are most prone to wear with new components. Damaged and obsolete parts are replaced and are end of line tested to ensure they perform to GM specifications. In addition, remanufacturing returns components back into service rather than processing as scrap or simply disposing of them. 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).
