Here's what a few of our valued customers have said about our products.
 
"If you do a internet search on the Ford Mustang GT500 or any recent Tremec transmission for that matter, you will find all sorts of issues with the synchros. Your Justice Brothers Gear Oil Treatment fixed them all. In fact it shifts more smoothly than ever. Fantastic."

R.F., Phoenix, AZ.

"JB-80® is awesome! We had a bolt on our 1951 Ford Tudor that our impact wrench wouldn't get off. It had 56 years of rust and road grime build up on it. I sprayed each bolt with JB-80® and waited 5 minutes. Most of them came out literally by hand. By literally, I mean, I broke the tension with a socket, then used my fingers."

"We would like to take the time to thank Justice Brothers for their superior product. We use Justice Brothers products in 2 Sprint Cars and in a Super Pro Drag car. We put it in the motor, rear ends, and steering. We have not lost any of these parts since using Justice Brothers additives. It is an awesome product that we would recommend for every race car. In addition we use Justice Brothers JB-80® for all lubricating needs and it is definitely superior to any other product on the market."

K.G., Martinsburg, WV

 "I have heard no complaints about your product, I am impressed on how efficiently they work. I use them in my '70 Chevy Super Sport Nova. Ford, Pontiac and Dodge. I plan to keep buying your products because nothing else can beat them period.

The Super Radiator Cooler worked phenomenally when I used it in my vehicle. I also use JB-80® along with most of the items you produce out in my garage. I will buy more in the future for other cars I am going to build and buy. Thanks."

My son tried it in his Monte Carlo which has over 70,000 miles on it, and he also got the same great results with his car."

J.C., Homosassa Springs, FL

 "Wow, what a product. I have just tried your Heavy Duty Engine additive and wow. I am very impressed. I run Royal Purple® 10w/40 oil and thought the power increase from that was good. However since adding your product to the oil the engine is definitely producing more power, is quieter, and runs a lot smoother. I have also added to the drive train, everything is just so much better. I own a 1986 Nissan R31 Skyline. CONGRATULATIONS ONCE AGAIN ON SUCH A FINE PRODUCT."

A.J., Australia

 "I would like to take the time to thank you and Justice Brothers for the fine additives that are made available for the car owner today.

I have used every type of additive know to mankind to reduce friction in a high performance engine, and I have found with a 12 month test on Justice Brothers oil additive and your transmission protectant that it is far superior to anything I have ever used.

By the way, I ran this test on a 488 cubic inch super-charged fuel burning engine that develops 1200 horsepower. If Justice Brother’s products will hold up under these conditions, they are A – OK!"

B.P., Tucson, AZ

 "I have been using your products by choice over the other lesser expensive brands for over 30 years. Keep on producing your quality products in the USA. I don't mind paying more for a quality product, to keep our people here employed."

A.L., Eveleth, MN

"During my 45 years of automotive engineering experience, I have built complete engines for auto racing. It has been my privilege of winning the Indianapolis 500 with an engine and car of my complete design. I have worked closely with the automotive industry for these many years; therefore I believe my opinions to be worthwhile. It has been my experience that the Justice Brothers products perform under the toughest conditions. I have had excellent results in both my Mercedes and Volkswagen cars and recommend them to anyone."

A.S., San Clemente, CA

 "In our opinion automotive chemicals are a rip-off, but Justice Brother’s products are the exception to prove these two die-hards wrong.

We operate a service station in Tulsa, Oklahoma, and last week we tuned a car with 30,000 miles for a traveling salesman. This was a late model car and we could not make the car perform at full throttle. Due to the persistence of our Justice Brothers salesperson, we put a Justice Brothers Emission System Cleaner Kit to the test. The final result was a very happy customer with a car operating at its peak performance.

You have proven to us that in the automotive chemical field, Justice Brother’s products are number 1 and we have yet to see a close second."
