Dorman 977-810 Fuel Injection Throttle Body

Electronic Throttle Body for Ram, Dodge, Jeep, and Chrysler

Dorman 977-810 is an OE FIX electronic fuel injection throttle body built for direct replacement on select Ram, Dodge, Jeep, and Chrysler applications. It uses a non-contact Hall effect sensor and a proprietary Sensor Shield shaft seal to better resist moisture, oil, and other contaminants that can affect throttle response.

With 100% new aluminum construction, this throttle body is designed to resist warping better than the original plastic unit. It also includes a specially designed mounting gasket for a complete repair. Compatible vehicle coverage includes 2008-2010 Dodge Dakota, 2008-2010 Dodge Ram 1500, 2008-2010 Dodge Viper, 2008-2010 Jeep Commander, 2008-2009 Chrysler Aspen, 2008-2009 Dodge Durango, 2008-2009 Jeep Grand Cherokee, 2011 Dodge Dakota, and 2011-2013 Ram 1500.
