J.C. Whitney JT27110012G Rear Brake Disc Rotor Plain Surface G-Coated Solid

The J.C. Whitney JT27110012G is an OEM-replacement rear brake disc rotor engineered as a direct-fit solution. This solid, plain-surface rotor is manufactured from high-quality cast iron and features a G-Coat corrosion-resistant finish to protect against rust and premature surface degradation during storage and break-in. The single rotor fits both the driver and passenger side (RH=LH).

Key Features:

• Plain surface design — smooth, non-drilled and non-slotted face for quiet, consistent OEM-style braking performance
• G-Coat protective finish — corrosion-resistant coating prevents rust bloom and extends rotor life
• Solid (non-vented) construction — cast iron solid disc engineered for rear brake duty cycles
• 5-lug hub pattern — matches OEM bolt circle for a direct bolt-on installation
• OEM cross-reference: 42431-33040 — meets or exceeds original Toyota specifications
• Replaces OEM part number 4243133040-PFM

Built as a drop-in replacement, this rotor restores factory braking feel and stopping confidence without the need for modification. Pair with compatible brake pads for a complete rear brake service.
