Function: Leaf spring pin (spring shackle pin) connects the leaf spring eye to the frame bracket or shackle, allowing controlled suspension articulation while securely transmitting vehicle load and road forces to the frame in ISUZU Elf FSR90 trucks.
The Leaf Spring Pin (OEM Numbers: 1-51161-004-3 / 1511610043 / 1-51161004-3) is a premium-quality, direct replacement suspension component designed specifically for ISUZU Elf FSR90 series trucks (also known as ISUZU FORWARD 5t models).
This spring shackle pin - also known as a leaf spring bolt, spring pin, or shackle pin - is a critical chassis component that connects the leaf spring eye to the frame bracket or spring shackle. It allows controlled suspension articulation while securely transmitting vehicle load, braking forces, and road shock from the spring to the frame. Proper function of this pin is essential for correct suspension geometry, axle alignment, and load-carrying capability.
