GM trucks DO NOT use a limited Slip Differential (except in the Quadrasteer models - Dana). Its use a Eaton G80 Locking Differential. Additives are not required!!
Quote
¨ Optional Equipment (G80 Order Code) on all GM two-wheel and four-wheel drive light trucks and sport utilities.
Benefits
¨ Improved traction differentiates the vehicle relative to other rear wheel and four-wheel drive vehicles on the market.
¨ Maintenance free; requires no lube additives.
¨ Enhanced towing and off-road performance.
¨ Patented carbon friction disc technology enhances performance and durability while reducing warranty claims.
Principles of Operation
¨ Wheel speed difference (left to right) in excess of 100 RPM will cause a flyweight mechanism to open and catch a latching bracket.
¨ The stopped flyweight will trigger a self-energizing clutch system, which results in the cam plate ramping against a side gear.
¨ Ramping increases until both axles turn at the same speed (full lock), which prevents further wheel slip.
¨ At speeds above 20MPH, the latching bracket swings away from the governor and prevents lockup from occurring.
Technical Specifications
¨ Automatic locking takes place within a fraction of a second, so smoothly that it is unnoticed by the average driver.
¨ Unlocking occurs automatically, once the need for improved traction is gone, and is unnoticeable to the average driver.
¨ Compatible with anti-lock brake systems
