Trusted by distributors, dealers, and 4×4 workshops across 50+ countries, XJX Auto Parts manufactures differential crown pinioin gears built to OEM tolerances — with the flexibility to customize gear ratios, tooth counts, and specifications for your specific market needs.
XJX manufactures ring and pinion gear sets for light-duty trucks, heavy-duty trucks, tractors, ATVs, and off-road vehicles. Every gear set is produced on Gleason equipment, ensuring consistent OEM-grade precision across our full range of 8,000+ SKUs.
We offer both lapped gear and ground gear finishing. Lapped crown wheel and pinion gear sets deliver reliable performance at a competitive price point, giving distributors and dealers stronger profit margins. Ground ring and pinion gear sets provide superior precision and durability, making them the preferred choice for racing and high-demand off-road applications.
