Dump truck leaf springs are crucial for load bearing and stable operation. For Howo 4-leg dump trucks frequently operating under harsh conditions, upgrading the leaf springs is a necessary solution to enhance durability and load capacity. This article will analyze in detail the replacement of the original 5-leaf springs with 12-leaf spring packs for Howo 4-leg dump trucks.
Why Upgrade Howo Dump Truck Leaf Springs?
Standard Howo 4-leg dump trucks are typically equipped with 3-leaf front springs and 5-leaf rear springs. However, in actual operation, many trucks are often overloaded, leading to broken springs and damage to the suspension system. Replacing the original springs with high-quality dump truck leaf springs, with more leaves like 12-leaf spring packs, will help:
- Increase load capacity: 12-leaf springs have better stiffness and elasticity, helping the truck withstand heavier loads without deformation or breakage.
- Improve shock absorption: Springs with more leaves absorb vibrations better, making the truck run smoother on rough roads and minimizing wear and tear on other parts.
- Extend vehicle lifespan: Upgrading dump truck leaf springs helps reduce damage to the suspension system, engine, and chassis, extending the overall lifespan of the vehicle.
- Enhance operational safety: A stable suspension system helps the truck operate more safely, especially when carrying heavy loads or moving on complex terrain.

Howo 4-Leg Dump Truck Leaf Spring Replacement Process
Replacing dump truck leaf springs on a Howo 4-leg truck from 5-leaf to 12-leaf is a complex process that requires technical skills and experience. It involves replacing many components, such as:
- Rear springs: Replacing 5-leaf springs with 12-leaf spring packs.
- Balance shaft: Adjusting or replacing the balance shaft to fit the new springs.
- Spring clips: Using 2 spring clips to enhance stiffness.
- Differential seal: Inspecting and replacing if necessary.
- Spring seats: Replacing spring seats suitable for the new springs.
- Leaf spring anti-friction pads: Installing anti-friction pads to minimize friction and wear.

Benefits of Using Leaf Spring Anti-Friction Pads
Leaf spring anti-friction pads for dump truck leaf springs are an important component that helps minimize lateral movement of the springs during operation. Installing anti-friction pads will help:
- Extend the lifespan of differential seals and balance shafts: Reducing friction and wear.
- Prevent spring clip breakage: Minimizing stress on the spring clips.
- Ensure operational safety: Helping the vehicle operate more stably.
