Web site is a bit hard to back navigate once you drill in. But overall the web site is great. really good in-depth descriptions and explanations (thanks Dan) that help you know you are looking at the right part. Some other web sites have no description! I called once to talk to someone and had a really good technical conversation, not just a salesman's perspective. Torque King prices are a bit inflated vs competition prices, which after reading the tech notes Dan wrote on the mainshaft specs and noting that most everything (shaft, gears) are imported sort of leaves you wondering how you could be paying for better quality (NV4500). Also I really liked the videos on teardown and assembly - very nice and very well done!
