Product Line Details

StopTech Sport Slotted Disc Brake Rotors are designed as one-piece replacement rotors for everyday street use with an emphasis on consistent braking feel. The slot pattern helps move heat and brake dust away from the pad surface, reduces glazing, and supports stronger wet and dry braking performance. This makes the 126.42087SR a practical upgrade for Nissan Frontier and Nissan Xterra rear brake service where OE fitment and improved rotor behavior both matter.

Common Brake Issues Addressed

• Brake fade from heat buildup during repeated stops
• Reduced initial bite caused by glazed pads
• Brake dust accumulation on the rotor face
• Corrosion on exposed rotor surfaces
• Noise or vibration associated with worn rear rotors

Installation Notes

Install on the rear right position only and verify rotor dimensions before service. This rotor uses a 6-lug pattern, vented construction, and a coated hat finish. Always inspect pads, caliper hardware, and hub condition during brake service, and follow factory torque specifications and bedding procedures after installation. Part number 126.42087SR should be matched to the confirmed vehicle application before ordering.

Quality Assurance

StopTech builds this rotor with a corrosion-resistant black e-coating and high-carbon metallurgy in most applications to support durability, quieter operation, and improved crack resistance. The 126.42087SR is engineered as a direct replacement rotor for factory brake systems, with OE-style fitment for the listed Nissan Frontier, Nissan Xterra, and Suzuki Equator applications.
