Construction & Design

The calipers are forged from high-strength aluminum alloy, providing an optimal balance of lightweight construction and durability. This forging process enhances structural integrity, allowing the calipers to withstand the rigors of aggressive driving and off-road conditions. The six-piston design distributes braking force evenly across the pads, reducing uneven wear and improving pedal response.

The rotors are crafted from premium-grade iron and feature precision-machined slots that help evacuate gases, dust, and water from the braking surface. This design promotes consistent friction and reduces the risk of brake fade during extended use. The red powder coat finish on the calipers not only protects against corrosion but also adds a custom look that stands out behind your wheels.

Installation & Fitment
