StopTech Part Number 126.44174CSR Cryogenic Slotted Front Right Sport Brake Rotor for Lexus GX460 and Toyota 4Runner

Description

The StopTech Part Number 126.44174CSR cryogenic slotted front right sport brake rotor is designed to deliver enhanced braking performance and durability for select Lexus GX460 and Toyota 4Runner models from 2010 to 2020. Featuring a split-core cast design with symmetric vane structures, this rotor ensures uniform heat distribution during braking, reducing the risk of warping and thermal stress. The black E-Coat anti-corrosive coating provides superior protection against rust and corrosion compared to standard spray paints, extending the rotor’s service life and maintaining a clean appearance over time.
All StopTech sport rotors are double disc ground to create a smooth, consistent friction surface that ensures optimal braking performance and increased longevity. An optional cryogenic treatment can be applied during manufacturing, which involves a deep, one-time freezing process that enhances the metal’s wear resistance and reduces residual stresses. Many fleet operators prefer cryogenically treated rotors for their extended service life and reliability, especially in demanding driving conditions. Additionally, the rotor’s directional curve vane design on selected applications improves gas and dust evacuation, providing increased initial bite and better wet weather response. These features combine to offer a balanced, high-performance brake component that meets or exceeds OEM specifications.
Designed as a direct replacement for your vehicle’s original equipment, this rotor’s precision machining and inspection for balance—tolerance less than 2 ounces—ensure a smooth and vibration-free braking experience. The slots on the rotor help evacuate gases, dust, and heat, further improving braking consistency and safety. Whether upgrading your existing brake system or restoring factory performance, the StopTech cryogenic slotted rotor provides a reliable, long-lasting solution for demanding drivers and fleet operators alike.
