Product Details

The StopTech Sport Slotted Disc Brake Rotors product line focuses on direct-fit brake rotors that retain stock-caliper compatibility while adding a slotted friction surface. On this Jeep Grand Cherokee front right application, the rotor measures 305 mm in outside diameter, uses a 72 mm center hole, and features a coated hat finish for added corrosion protection. The vented, straight-vane design supports heat management during repeated stops, while the slot pattern helps reduce glazing and maintain pad bite. Part number 126.67042SR is a practical choice for drivers who want a replacement rotor with a more performance-oriented surface than a standard smooth disc.

Common Brake Issues It Can Address

• Brake pad glazing on the rotor surface
• Reduced initial bite during normal or wet-weather braking
• Heat buildup during repeated stops
• Brake dust accumulation on the friction surface
• Corrosion on exposed rotor surfaces

Installation Notes and Tips

Install this rotor on the front right position only for the listed Jeep Grand Cherokee fitment. Confirm rotor dimensions, hub fit, and caliper clearance before installation, and inspect pads, hardware, and brake fluid condition at the same time. Proper bedding-in of new pads and rotors is important to help establish even pad transfer and consistent braking performance. Part number 126.67042SR is intended for factory brake systems and stock calipers.

Quality Assurance

StopTech designs this rotor with a black e-coating for corrosion resistance and, in most applications, high-carbon metallurgy for quieter operation, improved crack resistance, and stable performance under heat. The slotted surface and vented construction are engineered to support dependable braking on the 1999-2004 Jeep Grand Cherokee, front right.
