Dynatrac Hub Conversion

How many of you have had this conversion? I have noticed in a 4wheel parts add that it could add 4mpg. How much did this kit raise your mpg?

Re: Dynatrac Hub Conversion

I think the ads are making the claim for the newer dodges, not the fords. I think it's because the hubs never disengage on them.
By going to the Dynatrac hubs, the ability to disconnect the axle shafts and reduce rotating mass is supposed help alot.

My brother has the kit on his 06 dodge, and it gave him a noticeable milage increase.

Re: Dynatrac Hub Conversion

On the same note, I need to replace my kingpin balljoints -- the mechanic recommends Moog joints.

I'm tempted to have him install the Dynatrac free-spin kit while he's at it, but I'd like to hear some advice on that.

Is it worth ponying up an extra $1200 or so to get the full "combo" kit with crossover steering? Given that I have a 6" lift and 35" tires?
