This is the factory stuff! This clutch type unit features precise torque loading and puts the power to the ground by eliminating the traction loss of a spinning opposite wheel. The design of this unit incorporates a progressive rate of slippage that delivers a predicable on and off-road performance and reduced drive line component stress. Translation: It generally won't break axles or CV's! This is the perfect compliment to your Frontier for trail riding and rock crawling. A perfect match to go with the CALMINI transfer case gears.
