3/4 Spherical Bearing w/ SS 17-4 Race/440C Ball

The 3/4 Spherical Bearing with Stainless Steel 17-4 Race and 440C Ball from FK Rod Ends is engineered for high-performance suspension geometry correction and chassis dynamics tuning in road race, autocross, and street-driven platforms. This precision rod end bearing addresses alignment issues that arise from aggressive lowering, custom suspension builds, and extreme cornering loads where traditional steering or suspension linkage points deviate from factory geometry. Whether you're fabricating a competition suspension setup or restoring proper handling characteristics to a heavily modified vehicle, this spherical bearing maintains consistent articulation and load transfer across demanding driving conditions.

The stainless steel 17-4 race construction paired with a 440C hardened ball bearing delivers superior corrosion resistance and longevity compared to standard chrome-moly alternatives, particularly in vehicles exposed to salt environments or frequent washouts. The 3/4-inch spherical design allows full radial and angular freedom of movement, reducing bind and friction that can compromise suspension response and tire wear patterns. The tight tolerances and precision-machined geometry ensure minimal play at the connection point, critical for maintaining accurate bump steer curves and consistent steering feedback throughout suspension travel. The 440C ball element resists galling and seizure even under rapid articulation cycles, making it ideal for track-day vehicles and high-g cornering applications.

Builders and engineers typically integrate this bearing into tie rod ends, control arm links, and suspension arms where OEM bushings cannot accommodate custom suspension geometry or where metal-to-metal articulation is essential for precision handling. It suits vehicles running coilover setups, adjustable arms, and custom fabricated suspension components where repeatability and durability trump comfort-oriented isolation. Installation requires proper tooling for rod end assembly and adherence to preload specifications to prevent axial play while avoiding over-tightening that can induce friction. This bearing is compatible with any suspension or steering application measuring 3/4 inches in bore diameter and works seamlessly in both street and competition environments where reliability and precise geometry control are non-negotiable.
