Teraflex vs Dynatrac
I've looked and found no advantage or disadvantage to going with the teraflex d44 over the pr44. Other than the $150 price difference for going with the teraflex complete assembly on Northridge 4x4.
Seems as though everyone goes with the dynatrac. I'm wondering what makes the dynatrac so much better? Is it just the dynatrac is a more established and trail tested housing?
Does anyone have the teraflex 44 housing?

I couldnt figure out why go with a Teraflex 44 so I went with a Dynatrac prorock44 unlimited, ordered it last week.
My decision was also made by the fact Teraflex didn't exactly know when they would have stock next and a friend recently has a fantastic customer service experience with Dynatrac.

I went with the PR44, unlimited, with HD axle tubes. Think it is the best 44 on the market for the JK. The axle tubes are twice as think as the TF, the caster is adjustable, and it is Made in the USA, where as the TF is assembled in the USA.
For my money this is the better option.
Although, if someone can explain why a 3.25" diameter tube with .25" thick walls is stronger than a 2.5" diameter tube with .25" thick walls. I am not an engineer and it is not intuitive.

Our calculations show the 3-1/4"x 1/4" tube to be about 2% stronger than the 3"x 5/16" tube. These calculations help us understand beam strength (load support) but not necessarily impact strength. Thicker materials resist impact better than thin (obviously). A perfect example of this is late model vehicle driveshafts. Many late models cars have very large diameter shafts. These shafts are very thin wall and very light (frequently aluminum). They are as strong or stronger (for twist) than earlier shafts. Weight saving was the motivation. However, due the their thin wall design, they are much more susceptible to impact damage.

We did, I think your mistaking the tube diameter/thickness differences. TeraFlex can do a .50" thick tube option and possibly thicker. Also Tera44's are offered in a 0-3"/3-4" lift option for better caster.
