New S&S 143 in for serious personality change at Star Power!


T143 Engine for 2007-Up Touring Models




S&S T143 Engine fits 2008-'16 HD touring bikes except Twin-Cooled models.

If Bigger is Better, the T143 is the Best… The Biggest, baddest, bolt-in for a Stock Frame. All joking about size aside, it does matter. The S&S T143 Long Block engine for 2008-later Harley-Davidson® touring models is the largest S&S engine that will fit in a stock Harley-Davidson® chassis. It’s big, 143 cubic inches. ‘Nuff said. At double the HP of a stock motor the power of the T143 requires technical expertise for the 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 chassis and as such is not suitable for every situation.

Special fuel system is available from S&S - must be purchased separately. Requires an oil line kit - must be purchased separately.

• Fits in stock chassis – no cutting or frame modifications • S&S B3 cylinder heads CNC machined with 2 bolt exhaust flanges • S&S Super Stock T2 Crankcases with reed breather valve • 3 Piece Flywheels • S&S high flow oil pump and cam cover • S&S 635 Easy Start Gear Drive Cams and S&S 1.75:1 rocker arms for .674" total lift. • S&S Premium High Performance Tappets • 1 year parts warranty
