Multi-variant Ramp Set for Porsche 911, 944, and 968 LSD

The RacingDiffs ramp set includes multiple ramp positions that allow you to configure the differential locking characteristics depending on your driving needs:

• 30° / 30° – aggressive lock on acceleration and deceleration (2-way LSD)
• 30° / 60° – strong acceleration lock with moderate deceleration lock (1.5-way LSD)
• 50° / 65° – smoother locking behavior suitable for balanced performance driving

Designed for Porsche ZF limited slip differentials commonly found in:

• Porsche 911 Carrera (1972–1986)
• Porsche 944 Early Models (1982–1987)
• Porsche 944 Late Models (1987–1991)
• Porsche 968 (1991–1995)

• Forged construction for superior strength and durability.
• High-precision CNC machining ensures perfect plug-and-play installation.
• Chemically heat treated for maximum wear resistance.
• Multiple ramp angle positions allow adjustable locking behavior.

By changing the ramp angle configuration, you control how quickly and aggressively the limited slip differential locks.

• Adjust differential locking from approximately 25% to 100%.
• Configure the LSD as a 2-way or 1.5-way differential.
• Improve traction during acceleration.
• Optimize vehicle behavior during corner entry and exit.

For maximum performance, combine this ramp set with the RacingDiffs Performance Clutch Plate Set.

This combination significantly improves both the strength and the tuning capability of your Porsche LSD.
