Stoptech 127.42085R Disc Brake Rotor - Front Right

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Overview

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors (Part Number 127.42085R) are engineered for Nissan and Suzuki vehicles, including the Equator, Frontier, Pathfinder, and Xterra models. These rotors provide enhanced braking performance through a vented, slotted, and cross-drilled design that improves heat dissipation and reduces brake fade.

• Cross-drilled and slotted surface for improved cooling and debris removal
• Vented rotor design with straight vane style for efficient heat dissipation
• Coated hat finish to resist corrosion and extend rotor life
• Floating disc mounting for better rotor alignment and reduced stress
• Compatible with 6-lug wheel configurations and specific bolt circle diameter

Detailed Product Features and Specifications

This disc brake rotor features a nominal thickness of 1.102 inches (28.000 mm) and a discard thickness of 1.024 inches (26.000 mm), ensuring reliable wear limits for safe operation. The rotor's outside diameter measures 11.646 inches (295.800 mm), with an overall height of 1.504 inches (38.200 mm). The center hole diameter is 2.677 inches (68.000 mm), and it mounts using a 4.500 inch (114.300 mm) bolt circle diameter with six lug holes sized at 0.504 inches (12.800 mm). The rotor is vented with straight vanes to optimize airflow and cooling during braking. The floating disc mounting design helps reduce stress and improve rotor longevity. Note that this rotor does not include ABS tone rings or bearings.

About StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance by combining cross-drilled holes and precision slots. This design improves heat dissipation and helps evacuate gases and debris from the braking surface, which is critical for maintaining consistent brake feel and reducing fade under demanding conditions. The coated hat finish adds corrosion resistance, making these rotors suitable for daily driving and spirited use on Nissan and Suzuki trucks and SUVs.

Applications and Problem Solving

• Reduces brake fade during heavy or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner wheels
• Enhances rotor cooling to prevent warping and premature wear
• Provides consistent braking performance for Nissan Frontier, Pathfinder, Xterra, and Suzuki Equator

Installation Notes and Tips

• Ensure compatibility with your vehicle’s 6-lug wheel setup and bolt pattern
• Check rotor thickness before installation to confirm it meets minimum discard thickness
• Use proper torque specifications on lug nuts to avoid rotor warping
• Inspect brake pads and replace if worn to maximize rotor performance
• Do not reuse old hardware; replace mounting bolts if necessary
