Jeep CJ Big Power Brake Booster Kit

Our Jeep CJ Big Power Brake Booster Kit fits 1972-1986 . As we all know, after we put bigger axles and tires under our CJ’S, the small booster and master leave a lot to be desired. One of the most popular axle conversions is swapping Scout II Dana 44’s in to a Jeep CJ, or even 1 ton’s. This is something we have a lot of experience with. We also know that the stopping power is not desirable. We have figured out the answer for your booster needs. This is a bolt in unit with an 11″ dual diaphragm booster giving you way more boost over the stock 8″ booster. This kit is available with either a 1″ bore master cylinder or a 1-1/8″ bore master cylinder, depending on your needs. We have installed these Boosters in lots of Jeep CJ’s with great success. They fit V8 models without any issues, and we have them in inline 6 Jeeps as well. They come very close to the carburetor on the inline 6 models but they do fit. Jeep CJ Big Power Brake Booster Kit
