The new ProGrip II™ Brake System from Dynatrac™ gives owners of the 2007 and newer Jeep Wrangler (JK) exceptional braking performance with approximately twice the brake torque output of the stock system, while also improving brake-pedal feel and reducing pedal travel. The ProGrip II expands the Dynatrac brake system offerings for the Jeep JK, building on the success of the ProGrip which was introduced just a year ago.   The Dynatrac ProGrip II Brake System is a complete 4-wheel system, engineered in conjunction with StopTech to deliver balanced braking for lifted Jeep Wranglers and significantly reduce nose-dive.   The system includes:
  • Light-weight 13.5-inch, two-piece front rotors
  • 14.25-inch one-piece rear rotors that retain the integral parking brake system
  • 6-piston front and 4-piston rear brake calipers
  • Forged caliper bodies engineered for minimal deflection during braking
  • Calipers are hard anodized and then painted for corrosion resistance
  • Precision pad control to minimize brake noise
  • Pistons sized for optimum brake performance in this application
  • High-temperature silicone dust boots keep dirt, grime and moisture away from the piston pressure seals
  • Unique front and rear brake pads for optimum friction performance
  • Radial-mounted calipers make pad changes easy
  • New caliper brake lines and mounting hardware
