Regular servicing of your differential will increase its life span and reduce friction. ECS Tuning has created a kit that includes everything you need, including gasket material, drain/fill plugs, axle seals, and Redline 75w90 GL-5 gear oil. Redline gear oil is a favorite among BMW enthusiasts because of its low friction, high wear resistance properties.
Make your differential service count.
