At 4000-4400 pounds (depending on model), the Jeep Wrangler JL is no small mass to stop. That’s why engineers upgraded its factory brakes (compared to the JK Wrangler) to give it better stopping power. So how much difference can aftermarket big brake kits provide?
Rebel Off Road answered this by real life testing a set of Alcon Big Brakes on their JL. The results were impressive – a 40+% improvement over stock braking, cutting braking distance at 50-0mph from 104ft to just 61ft!
So yes, aftermarket big brake kits can make a huge difference in stopping the JL Wrangler. Check out the results and testing video inside.
