2017 Wrangler - JKUHeathen
Big Improvement
Easy to install and a good brake upgrade. Made a big difference in stopping with just the front upgraded. Stock brakes struggled to hold in 4L with my build but these have no issues.

great product
STOP, yes this is what this product does, my JKU did not prior to the Wilwood brakes. A bit pricey, but as they say you get what you pay for and these brakes are all of that. Thank you Extreme Terrain for the fast delivery and to Wilwood Sales rep for great info on this product.

6 piston from brake upgrade
These calipers and rotors are a must if you change tire size. Installation was a breeze. Follow the directions and look at the part numbers. I have a rubicon with a 2.5 inch lift. The brake lines that are with the kit are not long enough. Recommend buying 36 or 38 inch SBL with this kit so you don’t break anything while flexing.

2019 Wrangler - ChristianR
Does not fit a 2019 JL
The 90 degree adapters that come with this kit do not fit the JL calipers. It needs either banjo, straight or 45 degree adapters that are shown in the instructions but not included. Waste of time and money!

Upgrade from OEM
These brakes are an excellent upgrade on my 2015 Tundra. The difference they make is worth the extra cost. I’ll be upgrading the rear brakes to Wilwood soon.
