About PowerStop Brakes
When it's time to hit the brakes, PowerStop is a name you can count on. Since 1995, PowerStop has built a strong reputation for quality braking components that deliver dependable stopping power without breaking the bank. From everyday replacement brake pads and rotors to complete front, rear, and four-wheel brake kits, PowerStop has just about everything you need to get your vehicle stopping right. Their popular Z17 Series offers affordable factory-style replacements, while the Z23 Evolution Sport and Z26 Street Warrior lineups bring performance-focused upgrades to the table. For truck owners who tow, haul, or venture off-road, their Z36 Truck & Tow Series is built to handle heavier demands. With carbon-fiber ceramic brake pads, drilled and slotted rotors, upgraded calipers, and complete brake hardware, PowerStop knows how to put together a solid braking system.
Tired of worn-out rotors, squeaky brakes, or wheels constantly covered in brake dust? PowerStop understands that a good brake system should do more than just bring your vehicle to a stop. Their low-dust pad formulations, noise-reducing shims, and carefully matched brake kits are designed to make braking smoother, quieter, and more dependable. One thing we really like about PowerStop is how easy they make a complete brake job. Instead of piecing everything together yourself, many of their kits include the pads, rotors, and hardware needed for the job. Here at Elite Race Fab, we're big fans of quality parts that make sense for the money, and PowerStop fits that description perfectly. Whether you're refreshing your daily driver's brakes or upgrading your truck for some serious towing, PowerStop is a solid choice. After all, making horsepower is fun, but being able to stop when it counts is what really matters.
