Description

The Wavetrac Differential represents modern engineering for superior performance in a helical gear design. When one wheel experiences zero axle load, the Wavetrac's internal cam device creates load to maintain drive on the gripping wheel, preventing the common "open diff" behavior. Constructed from premium materials, the Wavetrac Differential features internal gears made from high-strength 9310 alloy steel. The diff bodies are precisely machined from case-hardened steel billet, ensuring durability. This differential is designed for the CHRYSLER LC/LX Getrag 648 axle (H226). This specific model, part number 48.309.186WK, is intended for use in Dodge, LC/LX Getrag 648 axle (H226) vehicles. It specifically fits the 2009-2014 Challenger SRT8 6.1L and 6.4L, as well as the 2009-2012 300C/Charger SRT8 6.1L and 6.4L models. All Wavetrac differentials come with a transferable, Limited Lifetime Warranty.
