Spring Pin 30×158
Manufactured from high-strength hardened steel, this pin provides a robust pivot and locking solution for spring-related connections, ensuring precise alignment under heavy loads and continuous suspension movement. Its 30 mm diameter and 158 mm length offer excellent shear strength and load distribution, reducing stress on surrounding components. The pin resists bending, wear, and vibration, maintaining stable suspension geometry even on rough terrain. Precision machining ensures smooth fitment and minimizes play, contributing to improved ride stability, reduced noise, and extended service life of the suspension system.
Key Features
