        Quality parts to replace the old rubber ones

        It always sucks to break a line but it does not appear that can happen with these easily.

        Get what you paid for...

        Not the greatest choice I’ve made when trying to save money. One of the two were defect, waist of time and more money. Spend the extra cash for a better product.

        Mammoth rear brake line

        A lot more beefy then stock break lines. Good copper washer replacements included, no leaks and works fully flexed on my 3.5 inch lift on my 2013 jk.

        great product for rock crawling

        gives you plenty of brake line to flex out on the trails, i have a 4 inch lift, and these work perfectly. well made, steel braided with rubber surrounding the lines.

        Super long brake lines

        Love these. I needed a long brake line and the ability to lose the brake line extension brackets and these definitely do the job. I’m running a 4.5 inch kit on 37s and at full droop I still have slack would definitely recommend to anyone looking for affordable longer brake lines.

        Great Product, Smooth Fit, Fast Shipping

        I chose to go with the braided brake line extensions instead of the bracket that relocates the stock lines. I was looking for longer life and durability, extra length for better articulation off-road, and a nice look. This product shipped quickly, fit properly, and is exactly what I wanted.
