• Compatible with a wide range of sedans, SUVs, trucks, and vans. Designed to replace units with worn bearings, chipped gears, or excessive backlash. Verify fitment using your vehicle‘s VIN or OE part number before ordering.
• Two design variants available. Open differential provides power to the wheel with least resistance—standard on most passenger vehicles. Limited-slip differential transfers torque to the wheel with more traction when slippage occurs—recommended for towing or off-road use. Select based on your vehicle‘s original configuration and intended application.
• Housing material variants offered. Cast iron version provides strength and durability for heavy-duty applications (trucks, towing, off-road). Aluminum version offers lighter weight for improved fuel economy and handling (common on passenger cars).
• Ring and pinion gears use hypoid design (pinion gear centerline below the ring gear centerline). Provides smoother and quieter operation compared to standard bevel gears. Pinion bearings positioned to minimize deflection under load—extends gear life and reduces wear.
• Mounting points, axle tube interfaces, and pinion flange patterns match OE specifications. No cutting, welding, or modification required when ordered with the correct fitment.
