This eCommerce site is about engine and transmission conversion adapters for 4WDs, both trucks and sport utility vehicles. The company specializes in manufacturing these conversion kits, and has been doing so since the early 70’s, so that when you are making your purchase online, you are backed up by decades of experience and savvy. AdvanceAdapters.com is very neatly designed to make your shopping experience comfortable and easy, even if you are not an experienced online shopper, though it is clear that its target audience has a solid background in mechanics and automobile mods. You can search the company’s catalogue, or browse the different categories, which include brand of car and kind of adapter, plus they carry technical literature in different formats (books, magazines, DVDs, etc); the site mainly sells retail, but if you are interested in bulk or wholesale purchases, get in touch with the company to get a quote.
