OS Giken NS044-HA Super Lock Limited Slip Differential LSD Nissan Skyline GT-R R32 R33 S13 S14

The OS Giken NS044-HA Super Lock LSD is a premium clutch-type limited slip differential designed for Nissan R32 and R33 Skyline GT-R and S13/S14 180SX manual transmission vehicles. This high-performance differential represents over four years of research and development, delivering exceptional durability and performance for both street and track applications.

Revolutionary Design Features:

• Houses up to 28 friction plates (up to 2x more than competitors) for true 100% lock capability
• Patented pressure ring design enables smooth, progressive locking with ultra-quiet operation
• Spline-through-side-gear design with miniaturized pressure ring maximizes friction plate capacity
• LSD case machined from a single billet piece to ensure uniformity and strength
• Relief cut-out for cone spring minimizes degradation and enhances durability

Superior Construction:

• All components chemically heat treated for maximum durability
• High-grade steel alloy construction throughout
• Precision-machined clutch disks on both sides to extremely tight tolerances
• No break-in period or rebuilds required due to superior engineering

Performance Benefits:

• Low preload with fully progressive 100% lock capability
• Feels like an open differential during slow turns and street driving
• Transmits maximum power to drive wheels under load
• Eliminates inside wheelspin and enables precise throttle steering
• Improved stability in all road and weather conditions

Tuning Capabilities:

• Ramp angles can be customized by swapping pressure ring and iron cross
• Lock progression timing adjustable with different pressure ring spring rates
• Optional TCD (Traction Control Differential) spec disks for increased oil cooling

The NS044-HA is supplied in Spec-S configuration, the standard setting recommended for both street and track use. This LSD requires either 5-bolt or 6-bolt side flanges depending on your specific application (sold separately). Suitable for sports car racing, gymkhana, drag racing, and daily driving.
