The black B/E-body kit covers several suspension service points, but the word master does not put every bushing in the box. Sort the spring-eye alternatives and end-link hardware against the parts list before the car is sitting on stands.
 
Fitment
1965-1972 B-body and 1970-1974 E-body applications as listed by model in the finder rows.
Dodge coverage includes Charger, Coronet and Challenger in their listed years. Plymouth coverage includes Barracuda, GTX, Satellite and Road Runner in their listed years.
 
Specifications
Part 5.18105G; black polyurethane Hyper-Flex components and the listed mounting hardware.
The rear spring list includes main-eye bushing alternatives: 2025 pieces for 426/440 models and 2024 pieces for other factory combinations. Verify the springs actually on the car.
 
Included
Upper control-arm bushings and their shells/sleeves/washers, front strut-rod bushings, front end-link components, lower control-arm bump stops, rear leaf-spring/shackle bushings and sleeves, and tie-rod dust boots.
Lower control-arm bushings and sway-bar frame bushings are outside the current kit-specific included-parts list. Plan those separately.
The updated kit list also specifies the grease tub.
 
Before ordering and installation
Follow the updated 5.18105 list (17185): upper control-arm bushings only. Lower arm bushings and sway-bar frame bushings require separate parts.
Match the spring-eye bushing alternative, sleeve and bolt to the actual spring. Engine labels alone cannot identify a spring someone swapped decades ago.
The list supplies different end-link hardware groups. Compare lengths and sleeves to the vehicle arrangement before tightening anything; check the factory service manual for torque and removal procedures.
Measure sway-bar diameters when ordering separate frame bushings and confirm bracket compatibility. Clean spring/shackle eyes and lubricate polyurethane contact surfaces as directed.
