Product Description

Powerbrake's X-Line Big Brake Kits are meticulously designed for superior performance, especially for 4WD vehicles. Utilizing high-grade aerospace aluminum billets, our multi-piston calipers are machined from solid billet for exceptional strength and rigidity. Our investment in state-of-the-art 5-axis CNC production ensures efficiency, allowing us to offer these premium calipers at competitive prices. The slim profile of our calipers reduces un-sprung weight and enhances wheel clearance, essential for 4WD trucks.

The X-Line 4WD calipers feature advanced laser-etched logos, stainless steel pistons, and European-sourced high-tensile cross-bolts, all contributing to their durability and performance in challenging environments. The calipers come in two anodized finishes: Red for maximum UV and temperature resistance and Dark Gray for extreme durability. Our proprietary MTR system provides a permanent record of the caliper's peak operating temperature, assisting in optimal brake fluid choice.
