Product Description
Dynatrac ProGrip™ Brake System, Jeep Wrangler JK, 5x5.5 Bolt PatternThis Dynatrac ProGrip Brake System accommodates the larger, 5x5.5 wheel bolt pattern that is popular on modified Jeeps. The 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 moderate and hard braking conditions compared to upgrades that only address the front brakes. 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 four-inch lift and 37-inch-tall tires. Measured g-force during moderate braking (1,000-psi brake fluid pressure) increased from 0.48 g with stock brakes to 0.63 g 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.
