| High Light | High-strength alloy steel U-Bolt Set ，Anti-corrosion coating Front Spring U-Bolt Set ，250 mm Overall Length Leaf Spring U-Bolt | ||
Front Spring U-Bolt Set 1-87870343-1 1878703431 for ISUZU CXZ51K 6WF1 — Verified OEM fit for heavy-duty leaf spring suspension clamping system. This U-bolt set is a critical clamping component of the front leaf spring suspension system, responsible for securing the leaf spring pack to the front axle housing and maintaining proper suspension geometry under heavy loads.
The front spring U-bolt set serves as the primary clamping mechanism that binds the leaf spring assembly to the front axle. It provides the force required to clamp the leaf spring and axle together, preventing lateral and longitudinal movement during vehicle operation. The U-bolt also maintains the correct spring curvature and alignment, which directly affects steering stability, tire wear patterns, and load distribution across the front axle.
ISUZU genuine U-bolt sets are manufactured from high-strength alloy steel with rolled threads for superior fatigue resistance, ensuring consistent clamping force throughout the service life of the suspension system.
Replace the U-bolt set when any of these symptoms appear:
