There is no such thing as a yukon Gear Set. Yukons are just repackaged gear set's. For example, a buddy ordered a set of gears from Randy's Ring and Pinion. They showed up the Yukon box. The gears were stamped US Gear. He hasn't had any major probs with the gears. So US Gear makes a good gear set. If you do a search on Pirates, there are tons of threads talkong about this. There are also two types of gears you can buy from Randy's. You can buy budget, or quality. The budgets are cheaper, but are made by some lesser name company.
