So that being said which free spin kit do you recommend and why? need to order one asap since truck is down...

 

It will take a while to get back your investment on free spin hubs I replaced my u joints $45 a piece

 

lots of other threads on this but basically dynatrak is the most $$ but the new low profile hubs are the **** and hardly stick out past the spindle. The solid axle kit has sealed abs sensors and tone ring, and comes with u-joints i believe. The ems is the most economical but in the past their kit didn't come with much assembled so you have to do more work, like driving in the races. It will take a while to get back your investment if you are talking just $$ saved on gas, but if you consider the cost of two new sealed unit bearings for when they fail, and the wear and tear on axle/drive shaft u-joints joints, cardon joint, front diff, and axle seals you will save i think its well worth it. plus 4lo with the hubs open = awesome 2lo gearing for backing heavy trailers around
