S&S Cycle T111 T-Series Long Block Engine - Wrinkle Black (Part# 310-0402A)
If you’ve been riding your 2007-2016 Touring Harley long enough, you know the feeling: the bike just starts to feel "lazy." You get on the highway, roll into the throttle to pass, and it’s just not there like it used to be. Most guys try to fix this with bolt-on air cleaners or different exhaust pipes, but that’s really just a band-aid. After turning wrenches on these V-Twins for years, we can tell you: the S&S Cycle T111 T-Series Long Block is the only real way to hit the reset button and get that "new bike" feeling back—actually, it’s better.This isn't just about gaining a few cubic inches. S&S engineered this motor to solve the specific heat and breathing issues that plague the factory engines. When you bolt this T111 in, you aren't just replacing an engine; you’re upgrading your entire riding experience.Why we recommend the T111 for our customers:
- Real-World Power: This motor isn't built for a dyno sheet; it’s built for the road. You get instant torque right off the line, which makes heavy Touring bikes feel light and punchy.
- Actually Runs Cool: One of our biggest gripes with stock Harley engines is how much heat they throw off in traffic. S&S uses better casting and head flow, which makes a huge difference on a 90-degree day in the city.
- Smoothness: We have installed plenty of these, and the balance is a night-and-day difference from a stock rebuild. You lose that annoying vibration in the handlebars, so your hands won't go numb on a long-distance run.
- Factory-Plus Finish: The wrinkle black powder coat is dead-on for the Harley aesthetic. It looks like it belongs on the bike from the factory.
Key Specs & Benefits
- Complete Assembly: This is a true long block. You get the engine pre-assembled from S&S, so you aren't stuck chasing down missing gaskets or worrying about valve train clearances.
- High-Flow Heads: S&S head work is legendary. They let the engine breathe easily, which is exactly why it makes power without sounding strained.
- Drop-In Fitment: It slides right into your 2007-2016 frame. We have never had to "force" one of these into place—the engineering is spot on.

Frequently Asked Questions
"Is my stock clutch going to be okay?"
The T111 makes more torque than your factory engine. It’s not going to destroy your clutch immediately, but it’s a smart move to inspect the plates while the motor is out. We always suggest a heavy-duty clutch spring at the very least."Do I really need a dyno tune?"
Yes. You are changing the engine's displacement and breathing characteristics. If you run your old map, you will run lean and risk engine damage. A professional dyno tune is the only way to finish this job right."How long does the swap take?"
If you’re doing it at home, plan for a full weekend and have a buddy help with the lifting. If you’re bringing it to us, we like to keep the bike for about a week. This lets us verify everything, get the break-in heat cycles done, and ensure the tune is perfect before you ride off.Related products
