Head
- Arcanum of the Earthen Ring - From The Earthen Ring faction. See my Cataclysm Tank Reputation Guide for more details.
Shoulder
- Greater Inscription of Unbreakable Quartz - From the Therazane faction. See my Cataclysm Tank Reputation Guide for more details.
Chest
You have two choices here. I am personally inclined to saying that Peerless Stats is the better of the two is you take all tanking aspects into consideration such ans survival, threat and damage. Of course if all your going for is a huge health pool then Greater Stamina would be for you.
- Enchant Chest - Peerless Stats - From enchanting or the auction house. Best in my opinion.
- Enchant Chest - Greater Stamina - From enchanting or the auction house.
Pants
- Charscale Leg Armor - From Leatherworking or the auction house
Boots
Three choices for this slot. With the new patch 4.0.6 lurking around the corner the Mastery enchant might not be the best choice for Deathknights due to the mastery nerf we are getting. Of course if your tank class relies heavily on mastery and you already have a speed boost go with the Mastery enchant. If you rely heavily on master and do not already have a speed boost I would go with the Lavawalker enchant. And if you are laking in stamina and/or need a speed boost go with the Earthen Vitality enchant.
- Enchant Boots - Mastery - From enchanting or the auction house.
- Enchant Boots - Lavawalker - From enchanting or the auction house.
- Enchant Boots - Earthen Vitality - From enchanting or the auction house. Personal best for now.
- Enchant Boots - Precision - From enchanting or the auction house.
Bracers
- Enchant Bracer - Dodge - From enchanting or the auction house.
- Enchant Bracer - Greater Expertise - From enchanting or the auction house.
- Enchant Bracer - Precision - From enchanting or the auction house.
Gloves
Two choices for this slot. Again with patch 4.0.6 and the DK mastery nerf coming I think DK and other tank the do not rely heavily on mastery or are laking in HP
