Show original supplier description

The Mopar Engine Mount Heat Insulator, part number 4578943AB, is an OEM replacement designed to manage engine heat and vibration. This specific insulator is intended for the right side of the engine mount and is compatible with select Dodge vehicles equipped with HEMI engines and manual transmissions. This component is crucial for vehicles with high-horsepower engines, helping to mitigate heat transfer to the vehicle's chassis and protect surrounding components. It is specifically designed for 5.7L and 6.1L HEMI engines found in 2005-2010 Dodge cars. The fitment details specify compatibility with the 6-speed manual Tremec transmission and the 6.1L V8 SRT HEMI engine. While this part is designed for a range of HEMI-equipped vehicles from 2005-2010, precise fitment is confirmed for the 2009-2010 Dodge Challenger with the 6.1L V8 SRT HEMI engine and the 6-speed manual transmission. Additionally, the 2010 Dodge Challenger R/T and SRT8 models with either the 5.7L V8 or 6.1L V8 HEMI engines are covered. Always verify fitment with your specific vehicle's year, make, model, trim, and engine configuration.
