COACH GUARD BRAKE CHAMBERS & COMPONENTS
Save money and time by using our genuine COACH GUARD DD3 brake chambers, either new or remanufactured.
COACH GUARD DD3 brake chambers are available remanufactured for replacement of both right- and left- hand horizontal units and can also be purchased as a new unit. If you prefer to rebuild units yourself, our genuine COACH GUARD components offer real value and are backed by a 1-year warranty.
ADVANTAGES INCLUDE:
- Standard 1-year warranty on new and remanufactured DD3 brake chambers
- 5/8" mounting nuts compared to 3/8" OEM nuts
- All remanufactured units utilize genuine COACH GUARD replacement parts, which are equal to or better than original OEM parts (see our rebuild comparison notes)
- Liberal core policies on core acceptance. If core is visually undamaged and in one piece, core credit is guaranteed!
- Significant price savings!
