Improve the performance and drivability of your vehicle with the Lexus GX470 – 2003-09 4.56 Gear Open Carrier from Revolution Gear and Axle. Whether you’ve upsized your tires or you’re seeking better torque for off-road or tow use, this gear set provides the right balance of strength and efficiency.
