run a ford HP44 for the front and be done. cheap, easy to find parts, and pretty good up to 37s (when running chromos)
will need to run adapters on the rear to convert to the 5-5.5 pattern
ran mine with D44/9" for about 3 years on 37s and was trouble free. wheeled it all over the country.
now I have big boy axles
