The T124 High Compression Long Block Engine is a high-performance long block option designed for compatible Touring applications. 🔧

Revised oil routing on '99-'06 Touring models removes the need for an oil line installation kit, simplifying installation and reducing plumbing complexity.

Made in the U.S.A. Not compatible with Softail models; '06 models will require '99-'05 style offset intake flanges.
