Designed specifically to remove a weak link in popular Dodge Ram 4x4 trucks, Dynatracs Free-Spin Heavy Duty Hub Conversion Kits replace the factory unit bearings with fixed spindles for superior strength, improved fuel economy, and smooth performance.
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

Yes, it works, saves tires and gas
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.

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.

Expensive but worth it
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.

This kit is for the straight axle trucks with the Dana 60 axle found in the 2500/3500. They don't offer a kit for the 1500's

Known for its brawny axle assemblies, Dynatrac got its start in the early 1990s when founder Jim McGean was building axles in his garage for off-road enthusiast friends. When others resorted to low quality parts from overseas, he took a stand and maintained production here in the states. Dynatrac's innovations include the high-clearance ProRock 60, Free-Spin hub conversion kits and heavy-duty DynaLoc locking hubs. Every axle manufactured undergoes 117 inspections during its assembly for quality assurance and the Huntington Beach, California-headquarted company has a deserving reputation as a manufacturer of high quality innovative components.
