Product Overview
High-Performance Cusco Type RS Front LSD Case for Evo X
Upgrade or rebuild your drivetrain with the genuine Cusco Type RS Front LSD Case (SKU: LSD454CA / LSD 454 CA). Engineered in Japan specifically for the Mitsubishi Lancer Evolution X (CZ4A) equipped with the 2.0L Turbo 4B11T engine, this differential casing provides superior gear alignment and eliminates housing flex under competition loads.
Whether you are running time attack, rally, or aggressive track days, factory front differential housings can suffer from torsional stress and microscopic casing flex. This flex causes uneven plate wear and sluggish lockup. The Cusco Type RS Front LSD Case delivers the structural rigidity necessary to keep your internal spider gears, side gears, and clutch plates in precise mesh under heavy lateral G-forces.
Key Features & Motorsport Benefits
- Authentic Cusco Type RS Engineering: Machined specifically to house Cusco’s low-initial-torque RS coil spring mechanism for lightning-fast lockup and reduced parasitic drag.
- Reduced Drivetrain Deflection: High-tensile Japanese alloy construction prevents casing distortion during hard standing launches and aggressive apex acceleration.
- Direct Fitment: Designed as a direct precision casing replacement for Evo X CZ4A 5-speed manual and compatible transaxles.
- Extended Service Life: Minimizes heat buildup and friction disc wear by keeping gear tolerances stable under prolonged track sessions.

Installation & Setup Notes
This product comprises the outer differential case housing unit. Internal side gears, pinion gears, cross shafts, and friction discs should be inspected and properly shimmed during assembly.
Always pair this unit with dedicated mechanical plate-type LSD gear oil (GL-5 rated) to guarantee smooth operation, minimize chatter, and maximize plate longevity. Professional installation and backlash check by a transmission specialist is recommended.
