OS Giken Super Lock LSD for 2013-2017 Toyota 86, Subaru BRZ, and Scion FR-S (TY421-HA)
$1,450.00
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2013-2017 Toyota 86, Subaru BRZ, and Scion FR-S models.
The OS Giken Super Lock LSD (TY421-HA) is a high-performance mechanical limited-slip differential engineered for maximum traction and predictable handling. Unlike traditional LSDs that use high initial torque, the Super Lock design utilizes a high number of friction plates to ensure smooth, progressive engagement while providing a complete lock-up under load. This design minimizes chatter and provides superior cornering stability, whether you are on the street or at the track.
- High-capacity friction plate design for smooth, total lock-up
- Improves corner exit speeds and overall vehicle control
- Precision-engineered for durability under high-stress conditions
- Retains street-friendly drivability with minimal noise and vibration
- Direct replacement for the factory differential unit
- Manufacturer Part Number: TY421-HA
