OS Giken HA091-HA Super Lock Limited Slip Differential Honda S2000 Mazda Miata

The OS Giken HA091-HA Super Lock LSD represents a revolutionary approach to limited slip differential design, engineered specifically for Honda S2000 (AP1/AP2 including CR) and 2004-2005 Mazda Miata manual transmission applications. This high-performance differential is the result of over four years of extensive research and development by OS Giken.

Key Features:

• Unprecedented capacity for friction plates with up to 28 plates total for true 100% lock capability
• Patented lock timing system delivers progressive, smooth, and quiet locking operation
• Miniaturized pressure ring with superior spline-through-side-gear design allows fitment of twice as many friction plates as competitors
• All components are chemically heat treated and constructed from high-grade steel for maximum durability
• Relief cut-out in LSD case minimizes cone spring degradation and enhances longevity
• Fully tunable with adjustable initial torque, lock progression timing, and customizable ramp angles
• Compatible with TCD spec disks for increased oil cooling and smoother operation

The Super Lock LSD delivers complete lock in a controlled manner, making it suitable for both aggressive street driving and racing applications. The advanced design translates to quick lap times, repeatable tuning, and consistent performance under demanding conditions.
