It's a fact. Adding larger tires to any off-road 4x4 is one of the first things people do. And with the extraordinary popularity of the JK Wrangler as a daily driven off-road platform, there are tens of thousands of lifted JK Wranglers running around in need of better braking performance.
The idea is simple: Larger tires equate to more ground clearance underneath the lowest point of your 4x4, but along with the positives comes the fact that larger tires (and wheels) reduce both the acceleration and braking of just about any 4x4. Bummer.
Luckily there are solutions. We've talked many times about regearing axles to regain some of the acceleration, economy, and feel when larger tires are added. That is a great, albeit expensive and intense, solution. We've also talked about improving the brake system to make your brakes slow down your big-tired 4x4 better. There are several ways that the average dirthead can do that, but as with regearing, most brake modifications aren't necessarily quick and easy.
The Dynatrac ProGrip Brake System for <a href=
Some JK Wrangler owners are more than willing to get fancy with lots of aftermarket brake modifications, but Dynatrac has an easy bold-on brake upgrade that doesn't even require bleeding the brakes. And despite our lack of scientific acumen, our simple tests showed that this simple solution dropped stopping times from 60 mph by nearly 15 percent compared to factory brakes. The Dynatrac ProGrip Brake system is available for all 2007-2018 Jeep JK Wranglers and includes new larger-than-factory brake rotors, new brake caliper mounting brackets, and new proprietary brake pads to give your Wrangler's factory front and rear brakes a huge improvement in both material and mechanical advantage.
The kit comes with detailed instructions, and the same basic steps apply to installation of the new parts for both the front and the rear. The front brake pads do come with anti-rattle pads that need to be trimmed to fit where the pads interface with the piston and caliper. We also noticed that the front pads have a break-in coating to help the new pads bed to the new rotors. The instructions suggest using some thread-locking compound on the hardware that holds the calipers to the slide pins, and the caliper brackets to the axle or knuckle. We
