I put this big brake kit on my JKU and it stops my 40" Kevlar MTR's on a dime!!!

Install is a breeze and materials are rock solid and built to last. My Jeep stops like a sports car now running on 35's.

Install was like any other brake job. They are a huge improvement over stock. Beware, they say minimum of 17" wheel. That leaves barely any clearance between the wheel and caliper for wheel weights. I had my newly balanced wheels have their weights ripped off after install. I recommend these brakes with at least 18" wheels.

Found this kit after unending frustration with long stopping distances on my 2010 Jeep JK with 37 inch tires. While I did not do the install personally, my friends Darren and Travis said it was a smooth install. I would also recommend the big bore master cylinder for this year. Also replaced rear rotors with the big (non-slotted) rotors and used the factory brakes. The difference is well worth every penny and I can drive with confidence Very positive stopping power!
