Axle Shaft (LH) Fiat

This Axle Shaft (OEM # 4999675) is an authentic Fiat component designed for the left-hand side of tractor differential systems. Crafted from high-strength alloy steel, it undergoes precision forging and heat treatment to withstand heavy loads, torsional stress, and harsh field conditions. The shaft’s splined ends and hardened surfaces ensure seamless engagement with the differential and wheel hub, delivering consistent power transfer for tasks like plowing, tilling, or hauling. Its OEM-grade engineering guarantees exact dimensions and compatibility, critical for maintaining drivetrain integrity and reducing wear on connected components.

The axle shaft features a robust design with precision-machined splines to prevent slippage under high torque. The heat-treated steel construction provides exceptional resistance to bending, shearing, and fatigue, making it ideal for Fiat tractors operating in rocky, muddy, or uneven terrain. Whether replacing a damaged shaft or upgrading during a rebuild, this component restores factory performance and reliability. Applications include Fiat agricultural tractors used in demanding fieldwork, construction, or forestry operations where axle durability is paramount.

Rigorously tested to meet Fiat’s OEM specifications (part # 4999675), this axle shaft ensures long-lasting performance. Proper installation requires careful alignment, use of OEM-recommended fasteners, and lubrication of splines with high-quality grease. Always verify compatibility using your tractor’s model number, VIN, or consult the service manual. Avoid aftermarket substitutes to prevent drivetrain failure and ensure optimal safety and efficiency.
