Borg-Warner Automotive Asbestos Exposure: Clutches, Mechanics & Claims
Borg-Warner Corporation and its Borg & Beck operations historically manufactured asbestos-containing automotive clutch products. The U.S. Securities and Exchange Commission states that BorgWarner and its subsidiaries were frequently named in personal-injury lawsuits alleging exposure to asbestos-containing automotive parts—mainly clutch assemblies for manual transmissions—that the company manufactured beginning in 1928. Published court records document asbestos-containing Borg & Beck clutches supplied to automobile manufacturers including General Motors.
An important corporate change occurred on October 30, 2019. BorgWarner transferred 100% of BorgWarner Morse TEC LLC—the entity that held BorgWarner’s asbestos-related liabilities and related insurance assets—to Enstar Holdings (US) LLC. BorgWarner’s SEC filings state that Morse TEC indemnifies BorgWarner and its affiliates for covered asbestos-related liabilities without a cap or time limitation. This is not a conventional Borg-Warner §524(g) asbestos bankruptcy trust, so this page does not invent Trust Payment Percentages or Scheduled Values.
🏢 Borg-Warner & Morse TEC History
Borg-Warner’s automotive history included transmissions and friction components sold under names including Borg & Beck. Later corporate succession placed legacy asbestos obligations with BorgWarner Morse TEC. The 2019 sale of Morse TEC separated those legacy liabilities from BorgWarner Inc.’s continuing automotive technology operations.

⚙️ Borg-Warner Asbestos Clutch Products
The strongest product evidence concerns asbestos-containing clutch facings and clutch assemblies. In Soto v. BorgWarner Morse TEC, the court described Borg & Beck riveting chrysotile-asbestos clutch facings to metal clutch plates and selling the resulting clutches to General Motors. Product composition changed over time, so the exact clutch, application and date remain important.
| Product / category | Evidence-based treatment |
|---|---|
| Manual-transmission clutch assemblies | SEC identifies these as the main source of BorgWarner asbestos claims. |
| Clutch facings | Court records document chrysotile-asbestos facings. |
| Borg & Beck clutches | Documented historical asbestos-containing products. |
| GM original-equipment clutches | Soto states Borg & Beck supplied asbestos-containing clutches to GM during the historical period at issue. |
| Automatic clutch packs | Cantrell record references a 1977 hygiene survey identifying Borg-Warner as supplier of asbestos-containing automatic clutch packs. |
| Replacement clutches | Potential exposure requires specific Borg-Warner/Borg & Beck product identification. |
| Brake products | Some litigation alleges Borg-Warner brakes, but product-specific asbestos proof must be established. |
| Modern BorgWarner products | Do not infer asbestos content from historical clutch litigation. |
Product Accuracy Rules

🌫️ How Borg-Warner Asbestos Exposure Occurred
Clutch work can disturb friction dust when asbestos-containing facings are involved. A 2011 federal decision quoted a 1972 Borg-Warner study reporting that a significant amount of manufacturing asbestos exposure came from loose fibers on clutch facings. Repair exposure must still be evaluated separately from manufacturing conditions.
| Activity | Potential pathway |
|---|---|
| Clutch removal | Can disturb accumulated friction dust. |
| Clutch replacement | Handling qualifying asbestos-containing clutch assemblies. |
| Abrading / sanding clutch faces | Mechanical disturbance can release dust. |
| Compressed-air cleaning | Can disperse dust if used around qualifying components. |
| Assembly work | Historical handling of asbestos clutch facings. |
| Box handling | Possible exposure alleged in Curtis; requires evidence of airborne fibers. |
| Sweeping / cleanup | Can re-suspend settled dust. |
| Nearby repair work | Potential bystander pathway requiring frequency/proximity evidence. |
Exposure Questions
| Question | Why it matters |
|---|---|
| Was the clutch Borg-Warner/Borg & Beck? | Product identification is fundamental. |
| Did that formulation contain asbestos? | Composition varied over time. |
| Was it original equipment or replacement? | Helps trace supplier/manufacturer. |
| What task disturbed the clutch? | Removal may differ from installation in dust generation. |
| How frequently did exposure occur? | Courts often evaluate frequency, regularity and proximity. |
| Can invoices, packaging or witnesses corroborate identity? | Strengthens evidence. |
⚖️ Claims, Liabilities & Compensation
BorgWarner did not resolve these liabilities through a conventional asbestos bankruptcy trust. Instead, in 2019 it transferred Morse TEC—the obligor for BorgWarner asbestos-related liabilities and policyholder of related insurance assets—to Enstar. SEC records state BorgWarner contributed approximately $172 million in cash to Morse TEC in connection with the transaction.
