This is the TeraFlex front right (passenger side) slotted and vented brake rotor, designed as a direct replacement for the front big brake kits (slotted version) or performance big rotor kits on Jeep Wrangler JK and JKU models made from 2007 through 2018. It replaces the factory front passenger side rotor for improved stopping power.
Constructed from high-quality cast iron, this rotor features mill-balanced, vented vanes to dissipate heat efficiently. The rotor includes performance slots (slotted design) to help manage gas buildup and wipe the pad surface clean. It's 13.3-inch (338 mm) in diameter—larger than the stock 11.9-inch rotor—and built with dual bolt patterns (5×5-inch and 5×5.5-inch) to fit a range of wheel setups.
Upgrading to this rotor delivers real-world benefits: shorter stopping distances, improved fade resistance under heavy loads, and cooler operation during spirited driving or off-road use. Drivers aiming for heavier wheels, larger tires (33-35″), or demanding terrain will appreciate the added strength and consistency—especially when paired with properly sized wheels (minimum 17-inch diameter) and quality pads.
