87mm Throttle Body

The GM 12740727 is an 87mm throttle body, featuring a cast aluminum construction in a natural finish. This genuine GM part serves as a direct replacement for various GM vehicles and engines. It comes with a throttle position sensor and is sometimes included as part of supercharger and intake manifold assemblies. This throttle body is specifically designed for engines such as the LT1, LT2, LT4, and L86. While some sources indicate fitment for 6.0L engines in older models (2017-2019 Silverado/Sierra HD, Suburban 3500HD), its primary application appears to be for 2014-2021 GM vehicles equipped with the 6.2L LT-based engines. It is compatible with various trims of the Chevrolet Camaro, Silverado 1500, Silverado 2500 HD, Silverado 3500 HD, Suburban, Tahoe, and GMC Sierra 1500, Sierra 2500 HD, Sierra 3500 HD, Yukon, and Yukon XL, as well as Cadillac Escalade and Escalade ESV models. Always verify fitment with the provided VIN for guaranteed accuracy.
