TeraFlex4304450 JK Rear Big Rotor Kit with Caliper Brackets

I already had the matching front brake kit. Just installed this rear kit today and I must say, it was immediately apparent that this added stopping power. There is much less dive and stopping distance decreased greatly.If you must choose between the Front and the Rear, get the front obviously....but definitely add the rear at some point. It does make a measurable difference. Keep up the fine work, Teraflex. 👊🏻😎

Needed to replace a rear rotor and caliper after one seized on my 2018 JKU. Decided to upgrade with TeraFlex Big Rotor kit. Ordered new calipers, as well. Rotor kit arrived several days early. Was easy to install, after getting old rotors off. Noticeable improvement in stopping performance. Will be adding front big rotor kit next.

I have the Mopar big break kit with master cylinder and booster. Huge difference! I tow a 3500 pound boat fully loaded and decided to add these to the Jeep. I couldn’t tell on city/highway driving HOWEVER! Towing, NIGHT and DAY! I had to make an emergency stop and that thing stoped! I could feel the stopping power. Jeep JKU 07, 35’s, 4.5 lift, steel bumpers and aluminum fenders. She’s a heavy lady.

Did both big brake front and the rear. They are awesome. No squeaking what so ever. Grease them right! Huge difference in breaking. Best upgrade yet. Extremely happy. Ended up not doing the steal lines (too long for 2.5 lift) and stock brake booster. Still huge difference. ❤️

Great kit for any JK running a big brake kit up front. I put the Crown kit in the front on my 2011 2 door. I would not recommend doing ONLY the rears in a JK as the braking is so biased to the front. I run this with the Hawk LTS pads and it’s an impressive system!

Put these on a 2013 JK Rubicon when putting on 38" tires. After putting them on (front and rear) the brakes felt better than stock with 33's. There are more expensive options out there, but theses work great. Bolted right up with no issues. I would Highly recommend this product.

If you are not actually in need of replacing your rotors or calipers, there is really not much difference in the rear kit. I did it just because I am doing the front so figured might as well. But no actual difference is felt in just the rear replacements.

A more confident brake feel. Did front and back. Much bigger rotor than stock. Happy with results and jeep looks a lot tougher.additional note: whomever is complaining about squeaks it has to be because they didn't do the install right, that goes with any brake kits. use brake grease generously on the clips, pads anything that rubs outside of the rotor/brakepad ceramic.when you don't use grease in these rubbing points, thats what makes it squeak.

Teraflex brakes are some of the better brake components you can get for a reasonable price. Definitely not cheap but great alternative to some other more expensive options.

Went on like a charm.
