Stoptech 127.63054L Disc Brake Rotor - Rear Left

StopTech Sport Rotor for Rear Left Braking

StopTech Sport Cross-Drilled & Slotted Disc Brake Rotor Part Number 127.63054L is a direct replacement disc for factory brake systems and stock calipers. It is built for the rear left position and uses a slotted X-drilled surface to improve heat management, pad bite, and wet or dry braking response.

Compatible With Chrysler PT Cruiser and Dodge Neon rear left applications, this rotor also suits select PT Cruiser trims with turbocharged front calipers and HO/Series 3 configurations. The coated hat finish and black e-coating help protect exposed surfaces from corrosion while the high-carbon metallurgy used in most applications supports quieter operation and improved crack resistance.

Product Details

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is aimed at drivers who want a direct-fit rotor with a performance-oriented surface design. On this 127.63054L rotor, the cross-drilled and slotted pattern helps move heat and brake dust away from the pad face, which can reduce glazing and support more consistent braking feel in everyday driving and repeated stops. The rotor measures 10.622 inches in outside diameter, 2.098 inches in overall height, and uses a 57.5 mm center hole with a 5-lug, 100 mm bolt circle.

Common Uses

• Replacing a worn rear left brake rotor on a Chrysler PT Cruiser
• Addressing brake pulsation caused by rotor wear or thickness variation
• Improving braking response after pad glazing develops
• Restoring braking performance on a Dodge Neon rear left brake position
• Updating a factory rotor with a slotted and drilled surface design

Installation Notes

Verify rotor dimensions, hub fitment, and brake pad condition before installation. Clean the hub mounting surface thoroughly and inspect caliper hardware, pads, and bearings during service. Because this rotor is a direct replacement for stock calipers, it should be matched to the confirmed rear left application and vehicle-specific brake setup listed above.

Quality Assurance

StopTech uses a coated finish and high-carbon metallurgy in most applications to support corrosion resistance, quieter operation, and improved crack resistance. Part number 127.63054L is built as a replacement brake rotor for factory-style systems and is specified for the confirmed Chrysler PT Cruiser and Dodge Neon rear left applications shown here.
