Custom Front Upper Strut Mount Replacement Manufacturers

Anhui Lianjun Rubber Technology Co., LTD. is a China-based Custom Front Upper Strut Mount Replacement Manufacturers operation focused on NVH rubber damper components for Mercedes-Benz and BMW chassis systems. We develop upper strut mounts, shock absorber top mounts, strut support bearings and related rubber-metal assemblies for replacement programmes, distributor stock and service-workshop supply. The range is built around OE-matched fitment, repeatable rubber compounding and complete suspension integration data rather than one-size generic parts.

Strut Mount Product Range

Our Products range supports both front and selected rear upper mount positions. The two main strut mount lines are:

• Mercedes-Benz Strut Mount: covers Sprinter 2-t/3-t, W201, W211 E-Class, C-Class/CLK, Vito W638, GLK, W246 B-Class and imported E-Class/C-Class applications. The range includes top mounts, integrated strut support bearings and mounting bushings matched to OEM part references.
• BMW Strut Mount: supports E28/E34, E46/E90, E38/E39, E60 and 7 Series platforms, including front mounts with bearing, rear suspension strut supports and shock absorber top mounts.

Within these lines, Lianjun Rubber supplies nearly 1,000 specifications across engine mounts, transmission mounts, driveshaft support bearings, bushings and strut mounts. That model coverage helps procurement teams consolidate Mercedes-Benz and BMW NVH replacement parts through one manufacturing partner.

Where Upper Strut Mounts Work

A front upper strut mount sits at the top of the suspension strut, connecting the damper, spring and piston rod interface to the vehicle body. The component carries vertical load, isolates road-induced vibration, maintains steering return and preserves correct camber movement. In many assemblies, the upper mount also contains a bearing that allows the strut to rotate smoothly during steering input.

The application split in our range reflects two different service needs. Heavy vans such as Sprinter and Vito require mounts with higher vertical load capacity and body-interface stiffness. Passenger-car platforms such as C-Class, E-Class, CLK, 3 Series and 5 Series require closer tuning of noise isolation, bearing torque and spring-seat alignment. Our engineering conversations therefore start with the exact chassis, not only the visual shape.

Material and Dimensional Considerations

Upper strut mount performance depends on the rubber compound, metal housing and bearing interface working together. We configure each project around the following variables:

• Rubber durometer and NVH tuning: the elastomer must absorb damper input without creating excessive body motion or steering vagueness.
• Metal housing and stud geometry: mounting hole centres, stud pitch, plate profile and body-side seating surface must match the OE interface.
• Bearing configuration: mounts with integrated bearings require correct rotational torque and protection against contamination ingress.
• Spring seat position: the upper seat must align with the coil spring diameter and load path to avoid side-load wear.
• Corrosion resistance and ageing: the compound and surface treatment are selected for road salt, high underbonnet heat and long service intervals.

Where a replacement programme requires a specific hardness, preload or bearing clearance, our R&D team works from the OE reference, sample and application requirements to prepare the appropriate configuration.

Configuration and Custom Development

We support both existing catalogue matching and custom front upper strut mount programmes. The R&D team can provide customized services for different moulds, allowing a distributor or technical buyer to develop an item that is already referenced on our products page but may need a different packing identity, compound adjustment or specific production batch format. Free sampling is available for visible quality confirmation before series production.

Typical configuration points include OE part number cross-reference, original sample or drawing, bearing type, stud pattern, plate coating, packaging label and required inspection documentation. Because our focus is Mercedes-Benz and BMW chassis systems, the engineering team can quickly identify platform variants and common interchange complications.

Quality Control and Production Consistency

Production takes place in a 13,000-square-metre facility at the Ningguo automobile NVH rubber damper production base in Anhui Province. Our quality system supports ISO9001 and automotive quality management requirements, covering incoming material control, in-process dimensional verification and finished-part batch inspection. We carry out delivery with attention to confirmed quantity, reference marking and export packaging so warehouse reception can proceed without unnecessary sorting.

For procurement managers and technical decision-makers, the key verification points are not only the part drawing. We also maintain batch traceability, OE reference identification, rubber-metal bond inspection and visual/critical-dimension acceptance before release. Free samples give buyers a practical confirmation of material, bearing feel and fitting geometry before placing a series order.

Installation, Acceptance and Maintenance Context

Our replacement upper strut mounts are designed for direct fitment using the vehicle manufacturer’s original fastening points and torque procedures. Service technicians should confirm that the bearing rotates evenly, the rubber shows no tearing or unbonded areas, and the studs align without forcing the body interface. If a vehicle has high mileage or the struts have already been replaced, replacing both front mounts at the same time helps maintain balanced NVH behaviour and steering feel.

For workshop and distributor programmes, we recommend controlled storage away from direct sunlight and oil contact, as well as first-in-first-out stock rotation. No special maintenance is required for the component itself; replacement is condition-based, normally when noise, bearing slack or visual degradation appears during service inspection.

Information We Use to Configure Your Solution

We prepare a specific proposal and quotation from the following project data. This keeps the technical scope aligned with the required vehicle variants and supply format.

Frequently Asked Questions

Are these upper strut mounts made for both Mercedes-Benz and BMW?

Yes. We stock and produce strut mount specifications for Mercedes-Benz passenger cars and vans as well as BMW 3, 5, 7 Series and related platforms. The catalogue includes front top mounts, rear strut supports, integrated bearings and application-specific mounting bushings.

Can you develop a strut mount that is not currently in your catalogue?

We can review the required OE number, original sample and drawing. Our R&D team supports customised mould development and pre-production confirmation, with free samples available for approval before series production.

Do you provide OE numbers for cross-reference?

Each product entry is presented with the corresponding OE reference where applicable. When a buyer or distributor has an OE number, we confirm the matching item and any interchange considerations before quotation.

What is the typical order and delivery approach?

We prepare a quotation from the vehicle model, OE number, quantity and packaging requirement. After sample confirmation, production is scheduled and delivered according to the agreed quality and quantity. For larger programmes, batch inspection and export packing are arranged in line with the order scope.

Can we receive samples before placing a bulk order?

Yes. Free sampling is provided so you can check material, bearing feel, stud alignment and packaging fit before committing to the main order.

Are the parts direct replacement units or universal components?

We focus on direct-replacement upper strut mounts and strut support bearings matched to the original interface. Universal or cut-to-suit suspension mounts are not the core of this programme.
