S&S T124 ENGINES FOR 99-06 BIG TWINS

 

 

Now with chrome gearcover & tappet covers!

S&S offers a truly complete 124" engine to replace the stock carbureted engines from 99-06 or fuel injected 99-05 engines. No engines are available for 06 Dyna™ or any 2007 model. S&S T124 engines are available in silver powdercoat, wrinkle black powdercoat and polished finishes. Match the original engine in your bike or go for a custom look.

Complete S&S T124 engines are designed to replace the existing Harley-Davidson®  Twin Cam 88®  engine in a stock chassis, making it easy to get the performance you want from your late model motorcycle. Take the stock engine out and put an S&S engine in. It's that simple!

Due to changes in S&S crankcase design, installation of an S&S T124 engine in 99-05 Dyna models requires oil line installation kit 31-0424. This kit contains a special transmission top cover and oil lines for Dyna models. For installation in 00-06 FLT models the stock transmission top cover may be used, but oil line installation kit 31-0425 is required.

Engines with internal counter balancers are not available from S&S to replace HD TC 88B™ engines. Complete engines are also not available for 06 Dyna or any 07 or later models.
