Duty Kit for Dual Rear Wheel (DRW) 35 Spline Outers
After talking to many newer Truck Owners, the Dodge
owners are looking for better mileage and less wear on the front axle joints.
Then both the Ford and Dodge owners are looking for cheaper maintenance cost
on the wheel/hub bearings. Plus if you are pulling a heavy trailer, you can
now use your truck in low range with out the bind of four wheel drive on hard
pack surfaces. This is real handy and keeps your clutch or auto transmission
Then we started looking at the existing options on
the market, and decided that there must be a more affordable solution out there.
The other kits we found were/are listed for $1800! After talking to a few different
manufactures we were able to put a couple different kits together for a great
The initial cost is hardly more expensive then replacing
a pair of hub bearings. The real payback on the investment is when it is time
to maintain the front wheel bearings, axle joint, drive shaft joints, and increase
in fuel mileage. When it comes time to inspect, repair, or replace the front
wheel bearings, the cost is now dropped to around $40-60 per side, not the $300-500
The design we based our kit off of is the oldest standard
of wheel bearings, two opposing tapered roller bearings on a common spindle
(commonly referred to as “Full Floating.”) The sizes of the parts
used are that of a truck with the same GVRW as your truck now is. This same
style of setup has been used by Dodge, GM, and Ford in there heavy ¾
ton to 1 ¼ ton trucks in both single rear wheel and Dual rear wheel,
and has been around and used for over 40 years. The only reason they did away
with the setup is that it takes longer at the factory to install a “Full
Floating” setup then to install a hub assembly.
We also investigated the reason why the Hub assemblies
fail. We noticed the bearing cage is made out of plastic. Also note the distance
the bearings are apart from each other. The one bearing fell apart once we removed
it from the housing!
The Extreme Duty kit uses upgraded Cromoly
4340 35 spline Axles and EMS Premium Lock outs. The Extreme Duty Kit was designed
for heavy plow trucks, pulling trucks and heavy offroading.
The benefits of the Hub Conversion are:
Stronger Axle Shaft 4340
Better Fuel Mileage
Easier Steering input(in 2wd)
Service-able Timkin Bearings
Eliminates front Drive shaft Vibrations, in 2wd
If you do break a stub axle, the bearing will not
Less wear on front end (u-joints, gears, drive shaft,
Driving with a Locked front end, in 2wd, will not
fight the steering
