The Son's of Hodir are a faction located in Storm Peaks at Dun Niffelem. They are the new faction in wotlk that will give you shoulder enchants, Honored=Good Enchant, Exalted=Best Enchant.
Prerequisite
In order to even begin gaining reputation with the Sons of Hodir you must complete the following quest chain-They Took Our Men! - Quest - World of Warcraft
Completion of the quest chain listed above opens up another quest chain and after you complete that you will be neutral with the Sons of Hodir-http://www.wowhead.com/?quest=12983
Methods of Gaining Reputation
Once you have reached Neutral with the Sons of Hodir you may begin completing daily quests for reputation or you may turn in Relic's of Ulduar, however I don't advise the latter because on my server at least they are way overpriced.
