S&S Catalog #55 coincides with S&S Cycle’s 55th anniversary in the high performance v-twin industry. The organization of this catalog is generally the same as last years book, but with minor improvements to make it even easier to find what you need. This year S&S is offering some new exhaust and intake products to enhance our 4-Step offering, as well as the new T-Series Long Block engines that give our customers a tremendous value and save them money at the same time. The section for Harley-Davidson® Sportster® models has some exciting new products as well. No matter what you need in v-twin high performance products, you’ll more than likely find it in the new S&S Catalog 55.
