• Corrosion-related booster deterioration on the housing

Installation Notes and Tips

Verify the vehicle is a 2012-2017 Jeep Wrangler or 2018 Jeep Wrangler JK configured without a master cylinder before ordering. Confirm the master cylinder stud thread size is M8 x 1.25 and compare the original booster layout, diaphragm style, and mounting points to the replacement unit. The package includes the booster, instruction manual, and M/C neck seal.

For best results, inspect the vacuum supply, brake pedal linkage, and master cylinder condition during installation. If the original booster showed signs of fluid contamination or corrosion, address the source before installing the replacement.
