Product Description
CPP52105299AB FRONT 4WD ACTUATOR STEEL VACUUM LINE HARNESS FOR 2000-2002 DODGE RAM 5.9L CUMMINS
The CPP52105299AB Front 4WD Actuator Steel Vacuum Line Harness is a direct-fit replacement for the factory Mopar 52105299AB vacuum line assembly used on 2000-2002 Dodge Ram trucks equipped with the 5.9L Cummins engine and front axle central axle disconnect (CAD) system.
The factory steel vacuum lines commonly rust, crack, leak, or become damaged over time, causing intermittent or complete four-wheel-drive engagement failure. Replacing worn vacuum lines helps restore proper CAD actuator operation and reliable front axle engagement during 4WD operation.
This CPP Diesel replacement harness is engineered to match factory routing and fitment while restoring proper vacuum delivery to the front axle actuator assembly.

FAQ
What does the front 4WD actuator vacuum line harness do?
This vacuum line assembly routes engine vacuum to the front axle CAD actuator, allowing the front axle disconnect system to engage and disengage properly during 4WD operation.
What happens when the vacuum lines fail?
Damaged or leaking vacuum lines can prevent the front axle from engaging correctly, causing loss of four-wheel drive operation or intermittent engagement issues.
Does this replace Mopar 52105299AB?
Yes. The CPP52105299AB is designed as a direct aftermarket replacement for the discontinued Mopar 52105299AB vacuum line harness.
Will this fit all 2000-2002 Dodge Ram trucks?
This harness is intended for 4WD Dodge Ram 2500 and 3500 trucks equipped with the 5.9L Cummins engine and factory CAD front axle disconnect system.
Are these steel vacuum lines prone to rust?
