Stoptech 127.42029L Disc Brake Rotor - Front Left

StopTech Sport Rotor for Nissan Front Left

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor is a direct replacement disc for factory brake systems and stock calipers. This rotor is built for Nissan Frontier, Nissan Pickup, Nissan Pathfinder, Nissan D21, and Nissan 720 front left applications, with a slotted X-drilled surface that supports more consistent braking in wet and dry conditions.

Key Features

• Part number 127.42029L for front left fitment
• Cross-drilled and slotted surface helps move heat and brake dust away from the pad face
• 1-piece direct replacement design for factory brake systems
• Vented rotor construction with straight vane style
• Black e-coating helps resist corrosion on exposed surfaces
• High carbon metallurgy in most applications for quieter operation and improved crack resistance
• Coated hat finish for a cleaner installed appearance
• Compatible with stock calipers on confirmed Nissan applications

Product Details

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors are engineered for drivers who want a direct-fit brake rotor upgrade without changing the factory brake system. The drilled and slotted face helps reduce glazing, improve initial pad bite, and support heat dispersion during repeated stops. For Nissan Frontier front left brake rotor replacement, Nissan Pathfinder front left brake rotor replacement, and Nissan D21 front left brake rotor replacement, this rotor provides an OE-style fit with performance-focused surface treatment. Part number 127.42029L is also listed for Nissan Pickup and Nissan 720 front left applications.

Measured specifications include a 10.894 in outside diameter, 1.024 in nominal thickness, 0.945 in discard thickness, 1.543 in overall height, 6 mounting bolt holes, 4.882 in bolt circle diameter, and a 3.937 in center hole diameter. The rotor is vented, mounts behind the hub, and uses a straight vane internal design.

What It Helps Address

• Brake fade during repeated stops
• Pad glazing that can reduce braking response
• Excess brake dust buildup on the rotor face
• Corrosion on exposed rotor surfaces
• Noise and cracking concerns associated with lower-grade rotor construction

Installation Notes and Tips

Confirm rotor side and position before ordering; this listing is for the front left position only. Verify rotor dimensions, bolt pattern, and hub fitment against the vehicle before installation. For best results, inspect pads, caliper hardware, and hub condition during brake service, and follow the vehicle manufacturer’s torque and bedding procedures after installation.

Quality Assurance

StopTech Sport rotors use black e-coating for corrosion protection and high carbon metallurgy in most applications to support quieter operation and better crack resistance. This part cross-references no listed interchange numbers in the provided data.
