Detailed description

Part number 977-241 is an OE FIX electronic throttle body engineered as a standard replacement for vehicles that use an electronically controlled throttle system. The aluminum throttle body construction, 80 mm bore diameter, and integrated sensor package support accurate throttle response while simplifying replacement of a failed original unit. Dorman Sensor Shield technology adds a proprietary butterfly shaft seal to help keep moisture and oil intrusion from damaging the electronics again.

This throttle body is a practical choice for Ram 2500 and Ram 3500 owners dealing with drivability issues tied to throttle control. It also fits Ram 4500 and Ram 5500 applications in the listed years, making it a relevant option for heavy-duty Ram fuel injection service. The 977-241 cross-references Cardone Reman 67-7018 for the same application.

What it is used for

• Restoring throttle response after electronic throttle body failure
• Addressing contamination-related internal sensor damage
• Replacing a worn or malfunctioning throttle position control assembly
• Correcting idle quality issues tied to throttle body electronics
• Servicing gas fuel injection systems with an electronic throttle body

Installation notes and tips

Verify the inlet and outlet configuration, electrical connector style, and fitment notes before installation.
