As if the Dyantrac ProGrip wasn't good enough at being the best braking system available for the Jeep JK Wrangler, they released an all NEW ProGrip II at the 2015 SEMA Show and from what I'm told, it'll offer double the braking power. In other words, if you are running a big heavy JK pushing 40" tires and still want it to stop like a Ferrari, this is the kit for you.
