These calipers and rotors are MASSIVE! The brackets and pads fit perfectly. This makes HUGE improvement on stock brakes!
I added this kit as part of a TOTAL BRAKE SYSTEM UPGRADE on my 2013 JK Rubicon (JKUR). Teraflex builds and sells the pieces so you can upgrade what you like all at once or do it in stages. It isn't cheap but if you have a lift and bigger tires, this is a MUST DO upgrade. I added the Big brake kit with (from TF website - oversized 56mm dual piston calipers for increased clamping force and surface area, 13.3" Mill-balanced vented slotted rotor, Composite-resin, semi-metallic pads for excellent cold stopping power. *** INSTALLATION OF THIS KIT REQIRES MIN OF 17" WHEELS***). These calipers and rotors are MASSIVE! The brackets and pads fit perfectly.I also replaced the Master Cylinder Teraflex 4303450 Brake Master Cylinder and added stainless steel lines front and back (FRONT Teraflex Brake Line Kit For Front of JK Wrangler 26 inch with Hardware REAR Teraflex 4350310 Brake Line Kit at the same time. This upgrade makes a BIG difference in the Jeep's braking ability!!! and I can't recommend it highly enough. Watch the "tech" video (link below) to see how much this helps reduce stopping distance. At a min, add the caliper/rotors/pads. TF designed these pieces together as a system and I wanted to get maximum gains from this mod. I see it as critical to the safety of me and family. With 35" tires, lift and power/gear add-ons, the stock brake system was barely getting the job done... and that makes sense because it wasn't spec'd to take all the extras I was adding to it. When I pulled my boat, things got borderline dangerous sometimes. That said, I'm often surprised that brake upgrades seem to be an after thought (or skipped completely) for lots of folks that mod their rigs. I have several aftermarket parts from Teraflex and have had excellent luck with them so far. Their customer service is great and they produce Youtube videos (TECH VIDEO - https://www.youtube.com/watch?v=EkXMsHpUQ-Y. INSTALL VIDEO - https://www.youtube.com/watch?v=L3_6zIR8ODs ) for all the stuff they sell. This makes upgrades easy to install. I highly recommend this company and their products! Good luck!

Great performing product
Have a 2013 JKU with 38" tires. These breaks do a great job stopping the vehicle over the stock breaks. Would recommend to anyone running larger tires.

Worth every Penny if you have a heavy Jeep. Recommend upgrading the master cylinder/brake booster as well and my Jeep stops on a dime.

Great product
Installed the kit on a 2012 Rubicon. Have no problems with the brake kit, extremely heavy duty! I would suggest when buying you think about buying one of the high volume master cylinders to go with the kit. Once the brake kit was installed the stock master cylinder barley moved enough volume to get that stiff brake pedal back but I did get a firm functional brake pedal.

Incredible price on an incredible brake kit
Brakes were easy to install and made a huge improvement in braking power. With 35" tires my Jeep stops like a sports car now.
