Product Introduction

Structure

This cabin front suspension shock absorber bottom bracket adopts an integrated precision stamping and forming process with high-strength structural steel as the base material, featuring a streamlined triangular reinforced design to maximize structural rigidity while achieving lightweight optimization. The bracket is equipped with a central cylindrical pivot sleeve (precision-machined for shock absorber installation) and multiple counterbored mounting holes on the irregular contour edge for chassis fixation.

Performance

Made of high-grade high-strength structural steel, the bracket undergoes overall strengthening heat treatment, exhibiting excellent impact resistance and fatigue resistance, and can stably withstand the continuous alternating damping reaction forces generated by the shock absorber under heavy-duty vehicle operation. The gray electrophoretic coating has strong adhesion and provides superior protection against gravel impact, salt spray corrosion and industrial chemical erosion, maintaining stable mechanical properties in the temperature range of -40°C to 150°C.

Core Function

1. Serves as the core lower mounting carrier for the cabin front suspension shock absorber, providing a fixed pivot point to ensure the normal telescopic damping movement of the shock absorber.

2. Transmits the downward damping reaction force from the shock absorber to the vehicle chassis, and disperses the concentrated load to the larger stress-bearing area of the chassis through the triangular structure, avoiding local structural damage.

Ensures the precise vertical installation angle of the shock absorber, maintains the optimal matching state between the shock absorber and the cabin

Cabin Front Suspension Shock Absorber Bottom Bracket 810W41701-0076 for Sinotruk Sitrak

Every heavy-duty truck relies on a well-engineered cabin suspension system to absorb road vibrations and protect the driver’s comfort. The Cabin Front Suspension Shock Absorber Bottom Bracket (OEM: 810W41701-0076) serves as the critical mounting foundation that secures the shock absorber to the chassis frame on Sinotruk Sitrak trucks. Without a reliable bottom bracket, the entire front suspension assembly loses its structural integrity — leading to excessive cabin vibration, accelerated component wear, and costly downtime for fleet operators.

At Mettlead, we supply this genuine-spec bracket directly from our factory in China, offering wholesale distributors and aftermarket agents a dependable source with competitive pricing, strict quality control, and flexible order quantities. Whether you’re restocking your warehouse or fulfilling a bulk fleet order, this bracket is engineered to meet OEM dimensional and material standards right out of the box.

Key Features and Benefits of the 810W41701-0076 Bottom Bracket

This shock absorber bottom bracket isn’t just a simple metal piece — it’s a precision-machined structural component that plays a vital role in cabin ride quality and driver safety. Here’s what makes it stand out:

• OEM-Grade Fitment: Manufactured to match the exact dimensions and mounting points of the original Sinotruk Sitrak specification, ensuring a hassle-free bolt-on installation without modifications.
• High-Strength Material: Forged from premium-grade steel with appropriate heat treatment, this bracket withstands continuous dynamic loads, road shocks, and harsh operating environments without cracking or deforming.
• Corrosion-Resistant Surface: A protective coating shields the bracket from rust and oxidation, extending its service life even in humid, salty, or dusty conditions commonly encountered in mining, construction, and long-haul transport.
• Vibration Dampening Support: By firmly anchoring the shock absorber’s lower end, this bracket ensures consistent damping performance, reducing cabin oscillation and protecting sensitive electronic instruments inside the cab.
• Wholesale-Friendly Pricing: As a factory-direct supplier, Mettlead eliminates middlemen, which means better margins for distributors and agents who buy in volume.
• White-Label and Custom Packaging Available: Build your own brand identity by requesting neutral or custom-branded packaging tailored to your market.

Technical Specifications

Application Scenario: Where Does This Bracket Work?

The 810W41701-0076 bottom bracket is specifically designed for the Sinotruk Sitrak series of heavy-duty trucks. In practice, it sits at the lower mounting point of the cabin front suspension shock absorber, acting as the fixed anchor that connects the damper to the truck’s chassis frame.

Think of it this way: every time the truck hits a pothole, crosses a speed bump, or travels over rough terrain, the shock absorber compresses and rebounds. The bottom bracket bears all of that repetitive force, holding the absorber firmly in place so it can do its job. Over time — especially in demanding applications like mining haul roads, construction sites, or long-distance highway freight — the bracket endures millions of stress cycles. A worn or cracked bracket compromises the entire damping system, causing the cabin to bounce excessively and putting additional strain on surrounding components.

Consequently, fleet maintenance teams and aftermarket distributors serving the Sitrak market should keep this bracket in stock as a routine replacement item during scheduled suspension overhauls.

Frequently Asked Questions

What is the function of the cabin front suspension shock absorber bottom bracket?

The bottom bracket serves as the lower mounting point for the cabin front shock absorber. It anchors the damper securely to the chassis frame, allowing the shock absorber to compress and rebound properly. Without a solid bracket, the absorber cannot maintain its correct alignment, which leads to poor damping performance and increased cabin vibration.

How do I know when the 810W41701-0076 bracket needs replacement?

Common signs include visible cracks or deformation on the bracket surface, unusual rattling or knocking noises from the cabin front suspension area, and excessive cabin bouncing that persists even after replacing the shock absorber itself. Additionally, during routine maintenance inspections, look for elongated bolt holes or corrosion damage that could weaken the mounting integrity.

Is this bracket a direct fit for all Sinotruk Sitrak models?

Yes, the 810W41701-0076 is designed as a direct OEM-equivalent replacement for Sinotruk Sitrak trucks that use this part number in their cabin front suspension system. However, since Sitrak covers multiple model variants, we recommend confirming the OEM number against your specific vehicle’s parts catalog before ordering in bulk.

What material is the bracket made from, and how durable is it?

This bracket is forged from high-strength steel and undergoes heat treatment to achieve the required hardness and fatigue resistance. The surface is coated with an anti-corrosion layer to resist rust in harsh environments. As a result, it delivers a service life comparable to the original factory part under normal operating conditions.

Can I order this bracket with my own brand packaging?

Absolutely. Mettlead offers white-label and fully custom packaging options. You can supply your own artwork and branding specifications, and we’ll produce packaging that represents your company — helping you build brand recognition in your local market.

What is the minimum order quantity for wholesale buyers?

We maintain flexible MOQ policies to accommodate both trial orders and large-volume purchases. For specific quantity thresholds and tiered pricing, please reach out to our sales team directly for a personalized quote.
