Custom BMW Transmission Rubber Mount Manufacturers

BMW Transmission Mount Range

Our current BMW transmission mount program covers the most widely serviced platforms in the aftermarket. Each mount is produced against the OE part number and validated for dimensional fit, rubber hardness and bonded-insert retention.

Application Fit by Platform

Transmission mounts operate under a different load profile than engine mounts. They carry driveline torque reaction, isolate gearshift-induced vibration and maintain propshaft alignment under acceleration and braking. Our range is grouped by platform generation so procurement teams can match the correct mount to the vehicle population they service.

• E36 / E34 / E32 / E31 (LJ-132, LJ-133, LJ-194, LJ-195): Compact bonded rubber mounts for manual and automatic transmissions in 3, 5, 7 and 8 Series models from the early 1990s through late 1990s. These mounts use a single center stud or bolt-through design with a bonded steel interleaf.
• E46 / E39 / E38 (LJ-194, LJ-394): Mid-generation mounts with higher durometer rubber to handle increased torque output. LJ-394 also covers E65/E66 7 Series and ALPINA variants where the mount must manage higher static preload.
• E60 / E61 / E63 / E64 (LJ-482): Mounts for the 5 and 6 Series with revised bracket geometry and stiffer rubber formulation to support six-cylinder and V8 drivetrains.
• F20 / F21 / F30 / F31 / F80 (LJ-713): Current-generation compact mounts for 1, 2, 3 and 4 Series platforms, including M3 (F80) applications where higher lateral stiffness is required.
• F01 / F02 / F03 / F04 / F10 / F18 (LJ-726): Large-platform mounts for 7, 5 and 3 Series long-wheelbase models, designed for higher static load and improved isolation at highway speeds.

Materials and Engineering

Each BMW transmission mount is produced from natural rubber or a controlled NR/SBR blend selected for the required durometer, damping coefficient and temperature range. The rubber is bonded to zinc-plated or e-coated steel inserts using a chem-lok adhesive system, then cured under controlled pressure and temperature.

• Rubber formulation: Durometer matched to OE working range, typically 55–70 Shore A depending on platform and drivetrain configuration.
• Bonded inserts: Steel cores and mounting studs are shot-blasted, phosphated and adhesive-primed before molding to prevent bond-line failure.
• Dimensional control: Mounting hole positions, stud lengths and bracket angles are checked against OE reference data during first-article inspection and batch sampling.
• Fatigue resistance: Rubber compounds are formulated to resist compression set and ozone cracking over extended service intervals.

Configuration and Customization

We support both catalog production and custom development for BMW transmission mounts. For existing OE numbers, we produce from maintained tooling and can adjust rubber durometer within a defined range for specific fleet or performance requirements. For new references, our R&D center works from a sample, drawing or OE part number to develop tooling and validate the mount through dimensional inspection and static/dynamic stiffness testing.

Free samples are available for catalog items so distributors and technical teams can verify fitment, hardness and bond quality before committing to volume orders. Low MOQ applies to initial trial orders, with scaled pricing for container-level programs.

Quality Assurance and Acceptance

Our quality system operates under ISO9001 and IATF 16949-aligned processes. Each production batch of BMW transmission mounts undergoes:

• Dimensional inspection against OE reference data and customer-approved drawings
• Rubber hardness testing (Shore A) on cured samples
• Bond integrity verification through destructive pull testing on sample mounts
• Visual inspection for surface defects, flash and coating uniformity
• Batch traceability with production date, compound lot and mold identification

Information We Use to Configure Your Solution

To prepare an accurate quotation and production plan for BMW transmission mounts, we work from the following project inputs:

• OE part number or Lianjun model reference: The fastest way to match an existing tooled product.
• Target BMW platform and model years: Confirms the correct mount geometry and rubber specification.
• Transmission type: Automatic or manual, as some platforms use different mount configurations.
• Annual volume and order frequency: Determines production scheduling, pricing tier and packaging format.
• Packaging and labeling requirements: Neutral, private-label or customer-branded packaging with barcode and part number.
• Destination market: Affects documentation, coating specifications and any regional compliance requirements.
