Anhui Lianjun Rubber Technology Co., LTD. is a Custom Automotive Rubber Mounts and Buffers Manufacturers in China supplying NVH rubber damper elements for Mercedes-Benz, BMW, VW and selected commercial vehicle chassis systems. Our range in this category covers suspension rubber damper pads, coil spring pads, exhaust silencer insulators, auxiliary spring buffers, bump stops, rear axle buffer stops and leaf spring buffers. We support replacement aftermarket distributors, workshops and fleet programs with OE-referenced part numbers and consistent batch production.

From our facility in Ningguo, Anhui, we focus on rubber-to-metal and rubber-to-plastic bonded chassis components. This product group complements our wider Bushing, Engine Mount, and Rubber Buffer For Suspension ranges, allowing a single part-number set for multi-line suspension and exhaust service kits.

Where These Rubber Mounts and Buffers Fit

These components operate at the contact points between spring, axle, body and exhaust structures. Their role is to isolate impact, reduce structure-borne noise, prevent direct metal contact and maintain alignment under cyclic load. In vehicle service, the replacement window is usually dictated by rubber compression set, cracks, debonding or chassis noise rather than complete component failure.

  • Spring pads and damper pads sit between coil springs and body/control arm seats.
  • Bump stops and auxiliary spring buffers limit axle travel and soften end-of-stroke impacts.
  • Exhaust insulators and silencer holders isolate exhaust mass and thermal expansion from the body.
  • Leaf spring buffers cushion inter-leaf contact and overload contact on light commercial vehicles.

Product Range in the Others Catalog

Our current LJ-series references cover immediate fitment and cross-reference applications for Mercedes-Benz, Volkswagen, Chrysler/Dodge Sprinter and related platforms. Each listing carries OE reference numbers and, where relevant, compatible model ranges.

Materials and Engineering Characteristics

We select elastomer compounds for the load case and environment. Suspension pads and buffers require repeated compression, weather and oil exposure; exhaust insulators require heat resistance and long-term dynamic flex; coil spring pads require abrasion resistance where the spring terminates.

  • High-strength, wear-resistant rubber for high-contact suspension cushioning
  • Oil-resistant and aging-resistant compounds for spring pads and underbody locations
  • Rubber-to-plastic bonding for damper pads requiring shape retention under side load
  • OE-form geometry to avoid installation interference on matched models

Material hardness, modulus and compression set are matched to the part application, not treated as a one-compound solution across all references. This matters for progressive bump stops and auxiliary spring buffers, where the component must remain compliant during light contact and firm at full stroke.

Configuration and Customization Support

Our R&D center can support custom mold development for customers with a sample, drawing, original part number or defined load/deflection target. We then confirm material, insert bonding, surface finish, markings and packaging. Free samples are available for approved project discussions, allowing quality and fit verification before production commitment.

For standard replacement programs, we work from OE number and vehicle application data. For private-label or distribution programs, we can align part numbering, label format, carton marking and packing quantity with the customer's warehouse flow. Low MOQ is available for selected service parts and trial orders.

Factory and Quality Approach

Our factory occupies 13,000 square meters in Ningguo, Anhui, with production molding and finishing capability supporting nearly 1,000 product specifications. The facility is structured for stable, repeat batch production rather than one-off machining. We control incoming elastomer and insert material, in-process molding conditions, trimming and final visual/dimensional confirmation for each release.

We have maintained ISO9001-based quality management since 2013 and continue to apply automotive supplier quality practices for product identification, traceability and inspection records. Every part is tied to an OE or internal reference before packing.

Installation, Acceptance and Maintenance

Our matched components are designed as direct replacement parts. When the OE reference and platform match, installation follows the original service procedure; no additional drilling, cutting or shimming is required. During receiving inspection, we recommend checking part number, rubber surface condition, bond edges and spring or mounting seat contact. In service, visual checks for cracking, permanent compression set, separation from the plastic/metal insert and loss of clamping tension are the usual replacement indicators.

Information We Use to Configure Your Solution

  • OE part number or vehicle model, engine/chassis variant and production year
  • Target application: replacement, fleet service, aftermarket kit or private-label program
  • Estimated annual volume and initial trial quantity
  • Sample, drawing or required dimensional and hardness/load targets for custom parts
  • Packaging, labeling and carton marking preference
  • Destination and required delivery terms

With this information, we confirm the correct LJ reference or evaluate new tooling, material recommendation and production lead time.

Frequently Asked Questions

What types of rubber mounts and buffers are included in this category?

These are matched to Mercedes-Benz, VW, Chrysler/Dodge Sprinter and selected platform references.

Do the products use exact OE part numbers?

Yes. Each listing is referenced to an original equipment number and, where applicable, multiple cross-reference numbers. This supports aftermarket sourcing without uncertain cross-fitment.

Can Anhui Lianjun Rubber develop a custom buffer or mounting pad?

Yes. Our R&D team supports custom mold development from a sample, drawing or load/deflection requirement. We then provide material and configuration recommendations before sampling and production.

Is free sampling available?

Yes. Free samples are provided for approved project discussions, allowing fit and quality verification before order commitment.

What production evidence supports repeat procurement?

We operate from a 13,000-square-meter facility with nearly 1,000 specifications, ISO9001-based quality management since 2013, and application-focused factory inspection. Export experience covers multiple regions including Europe and the Middle East.

What minimum order quantity is required?

We offer low MOQ for selected service parts and trial orders. Final MOQ depends on the reference, whether tooling is existing or new, and packaging requirements.
