KIT HSU 124 07-17TCA BLK

124" Hot Set Up® Engine Performance Kit

  • For non-balanced Twin Cam models
  • Converts a stock engine to 124" using the stock crankcases
  • Include S&S Super Stock® 91 cc cylinder heads , 4.125” bore cylinders, forged big bore flattop pistons, S&S 4.625” stroke flywheel assembly, S&S 640 gear drive Easy Start cams, S&S premium tappets, S&S adjustable pushrods, roller rocker arms, and all hardware, gaskets and instructions
  • Made in the USA
  • EFI system must be recalibrated.
  • Fuel or ignition system not included.
  • All clearances and assembly specifications will need to be checked.
  • Although the engine is 0.960" taller than stock, there are no frame clearance problems, and a stock EFI throttle body will fit because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold.


  • Not for use on twin cooled motors. Will fit '06 Dyna. Not recommended for compression ratios higher than 10:1 for Tri Glide® or other three wheel models (including conversions) due to extra loads caused by the lugging nature of these bikes. Detonation and subsequent engine damage may result.
