S&S T143 Twin Cam long block engines

Size does matter. The S&S T143 Long Block engine for 2008 and later Harley-Davison Touring models is S&S's biggest and baddest engine that fits in a stock frame. It's big, 143 cubic inches. Since the introduction of the S&S T124 eleven years ago, it has continued to set the industry standard for aftermarket engines. The T124 has become the most sought-after choice for upgrading your late-model Harley-Davidson and remains a great choice today. However, there's a new sheriff in town. The T124's big brother has just arrived at the party. Doubling the HP of the stock engine, the power of the T143 requires technical knowledge for installation and tuning, along with an experienced rider. This is an ultra-performance/race engine. Longevity, engine noise, vibration and throttle sensitivity have all been compromised to reach this level of performance while fitting in a stock frame and, as such, it is not suitable for every situation. It is the buyer's responsibility to consider the suitability for their application. Engine noise and damage caused by abuse are not covered by warranty.
