l am switching a 2004 F150 9.75 rearend open carrier over to a limited slip Ford Trac Lok differential.Is there a good gear lube out there with a friction modifier already in it or should l just use regular gear lube and a small bottle of friction modifier?What brand modifier to get then?What do you recommend using?Thanks.
