Product Introduction

Structure

This cabin rear suspension top bracket (right) is an integrated stamped and welded component made of high-strength structural steel. It adopts a reinforced triangular structure with a lightening hole in the middle to achieve an excellent strength-to-weight ratio. It is designed with multiple precision-drilled mounting holes for fixed connection to the cab and chassis, and all bearing surfaces are finely machined. The whole part is coated with a black or gray electrophoretic anti-corrosion layer, with stable and reliable welding quality, fully compliant with OE standard dimensions.

Performance

Made of high-strength sheet steel and treated with overall reinforcement, the bracket features high rigidity, good fatigue resistance and strong impact load capacity. The surface anti-corrosion coating provides excellent protection against rust, salt spray, mud erosion and gravel impact. It works stably in a temperature range of -40°C to 120°C, ensuring long service life under heavy-duty truck operating conditions.

Core Function

1. Serves as the special upper mounting support for the right-side rear cabin suspension, providing a stable and reliable mounting base for air springs, shock absorbers and other parts.

2. Transmits and distributes the loads from the rear suspension to the cab frame, avoiding local stress concentration and structural deformation.

3. Maintains accurate installation position and angle of rear suspension parts, ensuring stable posture and smooth movement of the cab.

4. Improves the overall strength and safety of the rear suspension system, reducing vibration and abnormal noise during driving.

Frequently Asked Questions

What exactly does the Cabin Rear Suspension Top Bracket-Right do?

This bracket acts as the upper right-side anchor point for the cabin rear suspension system. It connects the suspension spring or damper assembly to the cabin frame, absorbing road-induced forces and keeping the cabin stable. Without a properly functioning bracket, the cabin may experience excessive movement, noise, and accelerated wear on surrounding components.

How do I confirm that part number 850W41701-5070 fits my truck?

The most reliable method is to cross-reference the OEM part number 850W41701-5070 with your truck’s parts catalog or VIN-based lookup system. This bracket is designed for Sinotruk Sitrak models equipped with the standard cabin rear suspension configuration. If you’re unsure, send us your vehicle details and we’ll verify compatibility for you.

What are the signs that this bracket needs replacement?

Watch for visible cracks or deformation in the bracket body, unusual cabin vibration or rattling noises from the rear suspension area, uneven cabin height (one side sitting lower), or loose mounting bolts that won’t hold torque. Any of these symptoms suggest the bracket has reached the end of its service life.

Is this bracket identical to the original Sinotruk part?

Yes — it’s manufactured to match the OEM 850W41701-5070 dimensional specifications, material grade, and mounting hole pattern. It functions as a direct drop-in replacement, so no drilling, welding, or adapter plates are needed during installation.

Can I order just one piece, or is there a minimum order quantity?

Mettlead accommodates both small trial orders and large bulk purchases. While we encourage volume orders for the best unit pricing, we’re happy to discuss quantities that match your immediate needs. Simply reach out with your requirements.

How should I store this bracket before installation?

Keep the bracket in its original packaging in a dry, ventilated environment away from direct moisture or chemical exposure. Although the anti-corrosion coating provides protection, prolonged exposure to standing water or corrosive substances can compromise the surface finish over time.
