OS Giken Super Lock LSD for 2000-2004 Honda S2000 & 2004-2005 Mazda Miata (MT Only) - HA091-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 2000-2004 Honda S2000 Base and 2004-2005 Mazda Miata Mazdaspeed (Manual Transmission only).
The OS Giken Super Lock LSD (Limited Slip Differential) is engineered to provide maximum traction and predictable handling for high-performance driving. Unlike standard clutch-type differentials that can be binary or harsh in their engagement, the Super Lock system uses a progressive locking mechanism that transitions smoothly from open to fully locked. This design reduces wheel spin during cornering and significantly improves stability under hard acceleration and braking.
Constructed with a high number of internal friction plates, this LSD offers superior durability and heat dissipation compared to OEM units. It is a direct internal replacement designed to withstand the rigors of track use and spirited street driving while maintaining quiet operation.
- Manufacturer Part Number: HA091-HA
- Transmission Compatibility: Manual Transmission (MT) Only
- Locking Design: OS Giken Super Lock progressive engagement
- Increased friction plate count for enhanced torque capacity and longevity
- Improves corner exit speeds and overall vehicle control
