Key Features:

PowerStop’s Semi Coated Rotor combines advanced engineering with practical benefits to ensure optimal braking performance and longevity. Key features include:

• Partial silver epoxy coating on the hat, outer edge, and vanes to resist rust and corrosion
• Manufactured to strict tolerances for Disc Thickness Variation (DTV) and runout, ensuring smooth, vibration-free braking
• Cross-hatched friction surface designed to promote optimal brake pad break-in and consistent pad contact
• Exact weight and vane count matching original equipment for guaranteed fitment and balanced performance
• 100% dynamically balanced to minimize noise and enhance smooth operation
• Direct bolt-on replacement requiring no modifications or special tools
• Painted hat and edges to maintain a clean appearance behind wheels over time

Construction & Design:

Crafted from high-quality cast iron, the PowerStop Semi Coated Rotor is engineered to meet or exceed original equipment specifications. The partial coating is strategically applied to areas most susceptible to corrosion, including the rotor hat, outer edge, and internal vanes, providing long-lasting protection against rust without compromising thermal dissipation. The cross-hatched braking surface enhances pad bedding and helps maintain consistent friction levels, contributing to reliable stopping power under various driving conditions.

Attention to manufacturing precision ensures minimal runout and thickness variation, which reduces brake judder and noise for a more comfortable driving experience.

Installation & Fitment:

This rotor is designed as a direct replacement for the rear brakes on select Dodge Ram trucks, fitting models from 2003 through 2008 depending on the series. Installation is straightforward and requires no modifications, making it an ideal upgrade for DIY enthusiasts and professional mechanics alike. Simply remove the original rotor and bolt on the PowerStop Semi Coated Rotor using existing hardware.
