Mopar part number 4238730 is a rear drum brake lower shoe return spring (also listed as "Spring, Lower Shoe Return"). It is one of the springs that retracts the brake shoes after you release the brake pedal. It is used in rear drum brake assemblies, not disc brakes.
 
It fits a wide range of Chrysler, Dodge, and Plymouth vehicles from approximately 1984 through 2007, including many front-wheel-drive Mopar platforms.
 
Examples include:
Chrysler LeBaron
Chrysler New Yorker
Chrysler Town & Country
Chrysler Sebring
Chrysler PT Cruiser
Chrysler Cirrus
Dodge Neon
Dodge Grand Caravan
Dodge Charger
Dodge Omni
The part has since been discontinued by Mopar
