Black Flag differentials originated from the demand for a quality product that could withstand the most hardcore of builds and be available at a competitive price. Understanding the aftermarket industry and product performance expectations, Black Flag produces high quality engineered and manufactured differentials at a great price.
The helical gear limited slip differentials were designed and engineered for performance both on and off the track. The torque biasing design allows for better vehicle control, reduces torque steer and improves traction.
Black Flag differentials uses premium quality, high strength alloy steel for its differentials. The gears are forged using SNCM616 steel, which is known to be stronger than SAE9310 steel. The housing and gears are double heat treated for increased strength and durability.
