Reviews: Dynatrac Free-Spin Heavy-Duty Hub Converstion Kits

due to injury, had to have mech shop do the install. It took them 2 days to install the kit.seems it shouldnt take that long,but it did.

way better than stock...the quality is obvious...I knoww it will save me money in the long run...wish I would have got these when the stock bearing assembly went out the first time...Better readable copies of the schematic would help but all in all not a bad install

I installed this kit on my 2004 Dodge Ram 2500 long bed, four door, 4WD, Hemi, auto truck. Took the old Dodge junk out of the front and put this kit in. Completely different truck, stopped eating and cupping the front tires, turns nice, no hopping, and rides quieter. Ran it now for about 6500 miles, 1200 mile highway trip and the rest local driving. Saw an increase in mileage from 10.0 average and 10.3 high sometimes, 12.8 highway, before the kit, to a 11.3 average, and 14.3 highway, so it is alot better. I am running Firestone MT lugs too, so it still helped. Truck weighs about 7900lbs, with tanks, and hitches. I know it is a Dodge, but it handles like my old F250 trucks, easy to install. Only thing I did not like, is the new studs are too long to put the hubcaps back on the front and lock under the lugnuts, so I doubled the lug nuts on 4 of them, and the hub cap sticks out a bit, but looks good. Solution is to put in the shorter studs if you have them on it from new. As far as customer service, very helpful, no issues, great tech support, as my wheel bearing on the old set went out two days before the kit came in. They expressed it to the house, no issues.

Much better than original parts!

This is the way Dodge should've sold the truck. Replaced two bearings on my '06 2500 Megacab diesel. When the third OEM "Unit" bearing needed replaced @ 215,000 miles, I looked at other options and found this kit. I have ran five tanks of fuel since the Freespin Hub Kit was installed and have picked-up 1.5 to 2 mpg depending on how I ran the truck. And the fact that the bearing are serviceable as well as economically replaceable makes this a no-brainer. Struggled with doing this to a truck with as many miles as I have but I will keep the truck and this just plain makes sense.

Improved my gas mileage

old hubs and u-joints were dried out at 35000km so replace joints with greasable ones.I used precision by federal mogul #464.kit is very well machined [...]

Truck drives better then brand new now, awesome!

This kit eliminates the bogus Ford superduty hubs and makes the wheel bearings replaceable and stronger too. Kit needs to be installed by someone with some knowhow as it's not for a rank amature. The kit is made tough and pretty much unbreakable

i got a 2.5 mpg on my dodge cummins 2500 4x4 they alredy paying for them selfs

This product is amazing...I can not really say go out and change your hubs today, but if you suspect anything wrong with the factory hubs these are the replacements. I now have the same performance that a friend has in his 2 wheel drive. I also have the piece of mind knowing that my universals are new and if my wheel bearing goes out it won't cost me near as much...Also Dynatrac is awsome when it comes to customer service.
