TENACI TBM-410 Torsen Limited Slip Differential – BMW 210K / 215K
High-Quality Helical Gear LSD – Smooth, Predictable Traction and Improved Driving Performance
The TENACI TBM-410 is a helical gear limited-slip differential developed for selected BMW 210K / 215K large-case differentials with a factory bolted ring gear.
Unlike conventional plate-type limited-slip differentials, the TENACI Torsen uses an internal helical gear system to distribute torque between the rear wheels according to available traction.
This provides smooth, progressive and predictable power delivery without the aggressive locking characteristics associated with some motorsport plate-type differentials.
Key Features
- Helical gear limited-slip differential (Torsen-type)
- Smooth and progressive torque distribution
- Improved traction during acceleration and cornering
- No conventional friction plates to replace
- Low-maintenance mechanical design
- Suitable for performance street driving, track days and other appropriate motorsport applications
- Designed for selected BMW large-case differentials with bolted ring gears

Important Fitment Information
Not all BMW 210 mm or 215 mm differentials are interchangeable.
BMW used different differential carriers depending on transmission, model year and final drive ratio.
The TBM-410 is intended for selected differentials with a bolted crown wheel. It is not a direct replacement for welded-ring-gear differential versions.
Before ordering, please provide:
- BMW model and production year
- Engine and transmission type
- Original differential OEM part number
- Final drive ratio
- Confirmation of bolted or welded ring gear, if known
Our team can help identify the correct TENACI differential for your application.
