CLINTON, Mo. – Champion Brand’s latest new product – Limited-Slip Friction Modifier Additive  – works with some diesel pick-ups to eliminate noise, vibration, and harshness associated with certain positraction, limited slip, and locking differentials.

Its robust formula improves mileage, less wheel-spin, creates more traction, longer drain intervals, and less wear.

By using Champion’s Limited-Slip Friction Modifier Additive at a 1:25 dilution in appropriate gear oils or at a 1:10 ratio to provide full factory  limited slip performance.

Champion friction modification technology has been shown to provide more durable friction modification than the major OEM technologies in SAE #2 friction durability testing with a variety of clutch plate materials. The additive has a high viscosity-index (VI) that provides relatively constant viscosity and film thickness with varying temperature change.

This premium friction modification technology has been lab tested and field proven in demanding high-speed police fleet trials – where fast acceleration, high torque, and low traction place severe demands on locking differentials. Surpasses OEM requirements

Champion Limited-Slip Friction Modifier Additive specific properties: Light-Amber color, 5.1 Viscosity @ 100°C cSt, Flash Point 385°F, 0.88 Specific Gravity. Composition Ingredients: Mineral Oil and small concentrations of proprietary LSD performance additives. 

Differential operation

Basically, a differential allows the inside and outside wheel to rotate at different speeds in a turn.

An “open-differential” is the simplest type of differentials utilized by many Diesel OEMs. In this scenario the differential allows the inside and outside wheels to turn at different speeds. 

Unfortunately, an open-differential cannot get the power to the wheel that has the least amount of traction. 

During straight-line acceleration, an open-differential often produces a “peg-leg” type burnout. This diminishes straight-line performance.  

An open differential will tend to spin the inside tire and diminishes the ability of the vehicle’s traction. There is a significant advantage to having both wheels pushing or pulling a diesel vehicle.

This was the purpose behind the development of limited-slip differentials (LSD). They were designed to work in both an “open” configuration and a “locked” configuration by limiting or controlling the amount of slip allowed in the differential. For a maximum straight-line acceleration in severe environments or under heavy load, the LSD would allow zero slip between the left and right drive wheels.
