  • VENDOR: Dynatrac
  • PART#: JK44-2X1125-B
  • YOUR PRICE: Regular price $1,124.00


The Dynatrac ProGrip™ Brake System has the larger, 5 on 5.5-inch wheel bolt pattern that is popular on modified Jeeps. The sytem 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 2007-2017 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
  • 5 on 5.5-inch wheel bolt pattern

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. If you have 17-inch wheels and would like to verify that they will fit with the ProGrip Brake System, click the link below to download the Wheel Fitment Instructions as well as the front and rear brake profile.
