These F106 spindles are machined from billet chromoly steel and are designed for heavy-duty F106 axle applications as a direct replacement or upgrade for worn factory spindle assemblies. These spindles are ideal for axle narrowing applications while maintaining stock bearing, seal, and location dimensions.

The spindle is bored to clear 2 1/6th 32 spline axle shafts, making it compatible with high-strength aftermarket axle configurations used in competition and off-road builds.

Each spindle retains factory-style bearing and seal fitment, ensuring straightforward installation and serviceability. Spindles are available in 19 spline or 34 spline configurations depending on axle shaft setup.

Please specify tube ID requirements in the order notes so proper fitment can be ensured for your axle housing configuration.
