The first thought most people have after lifting their Jeep Wrangler JK and fitting it with 35-inch or taller tires is, that looks cool! The second thought is usually, wow, this thing doesn't stop very well anymore. I need a brake upgrade! When you install larger and heavier wheels and tires on the popular Jeep JK, the stock brakes have a hard time bringing the increased mass to a stop. The result is that you lose confidence in your ability to bring the Jeep to a stop as needed and the fun-factor of the vehicle is reduced. The aftermarket recognized this need, and there are quite a few brake upgrades available. Dynatrac recently introduced its ProGrip Brake System for 2007-2015 Jeep Wranglers, which is unique in how it solves the braking issue. The goal for Dynatrac was to create a balanced braking system that improves the braking performance front and rear as much as possible without requiring the installer to bleed the brakes. The Dynatrac ProGrip Brake System comes with larger rotors for the front and rear, providing improved braking by moving the factory calipers farther from the axle centerline. The increased rear braking power provides balanced braking, reducing nose dive and dramatically improving the control of the vehicle in mild and hard braking conditions compared to upgrades that only address the front brakes. Significant research was done to select the optimum front and rear brake-pad linings to balance the system and provide additional stopping power. Fully instrumented testing showed lower brake pedal pressure and a reduction in stopping distances of up to 30 percent compared to stock brakes on a Jeep JK outfitted with a 4-inch lift and 37-inch-tall tires. Measured G-force during moderate braking (1,000-psi brake fluid pressure) increased from 0.48 Gs with stock brakes to 0.63 Gs with the Dynatrac ProGrip system. Another key advantage is that installation of the system does not require opening the brake hydraulics, thus avoiding the chore of bleeding the brakes after installation. Additionally, brake pedal feel and travel is improved after upgrading to the Dynatrac ProGrip Brake System. The system is a direct bolt-on for 2007-2015 Jeep Wranglers and it includes:
  • 13.50-inch front rotors with unique pillar-vented cooling design
  • 14.25-inch rear rotors with integral parking brake surface
  • Stronger caliper brackets designed using CAD/FEA and advanced engineering tools
  • Unique front and rear brake pads for optimum friction performance
The Dynatrac ProGrip Brake System fits Jeep Wranglers with 17-inch wheels (wheel spacers are required with 17-inch factory wheels), and the system will fit in nearly all aftermarket wheels without spacers. NOTE: This kit does not fit Mickey Thompson Sidebiter II wheels due to the unusual inner profile of the wheel.
