Product Introduction

This up push rod is a heavy-duty suspension linkage component designed for heavy-duty truck chassis systems. It features a robust, forged steel rod with a gray anti-corrosion coating, integrated with two large, cylindrical rubber bushings at each end. The bushings contain precision metal sleeves for pivot connection, and the rod body is marked with identification codes for traceability.

Performance

• Manufactured from high-grade forged steel for exceptional tensile strength, fatigue resistance, and dimensional stability.

• Equipped with high-density rubber bushings that provide controlled articulation and effective vibration isolation.

• Resistant to oil, dust, temperature changes (-40°C to 120°C) and road vibration.

• Ensures stable performance under full load, bumpy roads and frequent start-stop conditions.

Core Function

1. Serves as a critical linkage component in the suspension system, transmitting longitudinal and lateral forces between the axle and chassis.

2. Maintains proper axle alignment and controls axle movement, ensuring stable vehicle handling and preventing premature tire wear.

3. Absorbs and dampens vibrations and shocks generated by road impacts, reducing noise and improving driver comfort.

4. Contributes to overall vehicle safety and reliability by maintaining the integrity and effectiveness of the suspension system.

Key Features and Benefits of the WG9631523175 Up Push Rod

Forged Steel Construction for Maximum Strength

Unlike cast alternatives that can crack under shock loads, this push rod is manufactured from forged steel, which provides superior grain structure and fatigue resistance. As a result, it withstands the repetitive stress cycles encountered in heavy haulage, mining, and construction applications without deformation.

Integrated Rubber Bushings with Metal Sleeves

Each end of the rod features a large cylindrical rubber bushing pressed around a precision-machined metal sleeve. These bushings absorb road vibrations, reduce NVH (noise, vibration, harshness) transfer to the chassis frame, and allow controlled angular movement at the pivot points. Consequently, drivers experience smoother rides and reduced component wear.

Gray Anti-Corrosion Coating

A factory-applied gray protective coating shields the rod body from moisture, road salt, and chemical exposure. This surface treatment significantly extends service life, especially in humid tropical climates or regions where de-icing agents are commonly used.

Laser-Etched Identification Codes

For full traceability and authenticity verification, the rod body carries clear identification markings including the OEM part number WG9631523175. This makes inventory management straightforward and helps prevent counterfeit parts from entering your supply chain.

Wholesale-Friendly Pricing and Packaging

Mettlead ships directly from our China-based warehouse, eliminating middlemen. Moreover, we offer white-label and custom packaging options so you can resell under your own brand identity without additional repackaging costs.

Application Scenarios

The Up Push Rod C WG9631523175 is specifically designed for the rear suspension system of Sinotruk heavy-duty platforms. Here are the primary scenarios where this component is needed:

• New Vehicle Assembly: OEM-spec push rods are installed during production of HOWO, HOWO A7, and Golden Prince trucks to establish correct rear axle geometry from the factory floor.
• Rod Body Deformation Replacement: After years of heavy loading or impact from rough terrain, the rod body may bend or twist. A deformed push rod causes axle misalignment, uneven tire wear, and compromised handling — making timely replacement essential.
• Rubber Bushing Wear Replacement: Over time, the rubber bushings deteriorate due to heat cycling, oil contamination, and mechanical fatigue. Symptoms include clunking noises during acceleration or braking, excessive axle play, and poor straight-line stability. Replacing the complete push rod assembly restores factory-level performance.
• Chassis Overhaul and Repair: During major chassis rebuilds following accidents or scheduled heavy maintenance, all suspension linkage components — including upper and lower push rods — are typically replaced as a set to ensure uniform performance.

Frequently Asked Questions – WG9631523175 Up Push Rod

What is the difference between an up push rod and a lower push rod on HOWO trucks?

The up push rod (upper thrust rod) WG9631523175 is mounted higher on the rear suspension and primarily handles longitudinal forces — traction during acceleration and resistance during braking. The lower push rod, positioned beneath it, bears more of the vertical load and lateral forces. Both work together to keep the rear axle properly aligned, but they are not interchangeable due to different lengths, bushing sizes, and mounting angles.

How do I know when the WG9631523175 push rod needs replacement?

Watch for these telltale signs: metallic clunking or knocking sounds from the rear axle area during acceleration or braking, visible cracks or chunks missing from the rubber bushings, excessive free play when the rod is manually inspected, or any visible bending or twisting of the rod body. Additionally, if your tires show irregular wear patterns on the rear axle, a worn push rod could be the culprit.

Is this push rod compatible with all HOWO truck models?

The WG9631523175 is designed for Sinotruk HOWO, HOWO A7, and Golden Prince (Jin Wang Zi) models equipped with the standard rear air suspension or leaf spring configuration that uses this specific rod length and bushing diameter. However, because Sinotruk has produced various chassis configurations over the years, we recommend confirming your VIN or existing part number before ordering in bulk.

Can I replace just the rubber bushings instead of the entire push rod?

Technically, bushings can be pressed out and replaced individually. However, in practice, most workshops replace the complete assembly because the labor cost of bushing replacement often exceeds the cost of a new rod — especially at wholesale pricing. Moreover, a new complete rod guarantees that the steel body has no hidden fatigue cracks that could lead to sudden failure.

What is the expected service life of this up push rod?

Under normal operating conditions (paved roads, standard loading), the WG9631523175 push rod typically lasts 200,000–300,000 km before bushing degradation requires attention. In severe-duty applications such as mining haul roads or heavily overloaded conditions, this interval may shorten to 100,000–150,000 km. Regular inspection during routine maintenance helps catch wear early.

Do you supply matching suspension components for a complete rear axle rebuild?

Yes. Mettlead stocks the full range of Sinotruk rear suspension components including lower thrust rods, V-rods (reactive rods), stabilizer bars, air spring assemblies, shock absorbers, and all associated hardware. Ordering as a set ensures dimensional compatibility and simplifies your procurement process.
