Japan-sourced Cusco clutch-type LSD for the Datsun S30Z, imported directly and available for R180 and R200 differentials. ZSM works with Cusco USA to bring these units to market — rebuilt with all new OEM bearings and seals, and available ZSM-tuned for the S30Z chassis.

Why Cusco

Cusco is the only LSD manufacturer on the market with a forged differential housing. The forged construction optimizes strength-to-weight ratio and reduces drivetrain losses. The generous windowing on the housing allows significantly more oil to interface with the clutch plates than any competing LSD — resulting in smoother engagements, better modulation, and lower operating temperatures. The clutch plates stay saturated, the system stays consistent.

What You're Getting

This is the physical Cusco LSD unit, Japan-imported and rebuilt by ZSM with all new OEM bearings and seals. Units are available for both R180 and R200 differentials. If you want ZSM S30Z-specific tuning dialed in before it ships, see our R200 / R180 Cusco LSD — ZSM Tuned service listing.
