S&S CYCLE T124 Low Compression Long Block Engine — 124 in³ displacement, 10.2:1 compression – 07-17 Dyna, 07-16 Touring, 07-16 CVO, 09-16 Trike, 08-11 Softail

⚙️ Built for dependable street performance, this low compression long block delivers proven durability and straightforward installation for many touring and cruiser applications.

The package includes Super Stock™ heads, a T2 crankcase, a high-flow oil pump, a cam cover, and easy start 585 gear drive cams.

• Special head machining accommodates stock-length intake manifolds (manifold size 405).
• Stock-style breathing system is compatible with stock and most aftermarket air cleaners.
• No fuel system or ignition components are included; this is a long block only.
• Revised oil routing on '99–'06 touring models removes the need for a separate oil line installation kit.
• Cylinder heads are '99–'05 style; owners of '06 models will need the '99–'05 style offset intake flanges.
• Heads are machined to compensate for non-stock cylinder length while keeping breather vent bolt locations in the stock position to allow stock air cleaner back plates to bolt up.

Installation tip: verify accessory and chassis compatibility before purchase. 🔧
