The Dodge Challenger Message Board

today i did the rear drum brakes,putting new hardware and getting my e brakes to work. while i was doing this i discovered blue large numbers on top of the leaf springs and i also saw the paper tag around the axle. the large blue numbers read p 4452985 on one side,the other side just faintly reads out as the same #?

the paper axle tag reads 081 343 the rest i cant read.

any idea what these codes mean?

P4452985 is the Mopar Performance replacement leaf spring, driver side ; the passenger side would be P4452984.
