Construction & Design

The calipers are forged from high-strength aluminum alloy, providing an optimal balance of rigidity and weight savings. This construction enhances braking responsiveness while reducing unsprung mass for improved suspension performance. The drilled rotors are crafted from premium-grade iron to withstand high thermal loads and resist warping during aggressive driving or off-road use.

The radial mount design of the calipers increases stiffness and improves pedal feel, while the narrow profile allows for better clearance with aftermarket wheels and suspension components. The red powder coat finish not only protects against corrosion but also complements the rugged styling of the Jeep Wrangler JK.
