S&S CYCLE - 310-0402B - T111 Long Block Engine - '06-'17 Harley-Davidson Screamin Eagle Ultra Classic Electra Glide, Dyna 35th Anniversary Super Glide
S&S Cycle's T111 Long Block is a short-stroke torque engine, running a 4-1/8" bore and stroke to cut vibration and friction while extending engine life on '06-'17 Harley-Davidson models. Gear-drive 585 Easy Start cams replace the stock chain-drive setup and eliminate manual compression releases, while high-flow TC3 oil pumps deliver more consistent pressure and scavenging than the factory unit. Heads are machined for stock-length manifolds and factory EFI throttle bodies, and the case is cast from aircraft-grade 356-T6 aluminum to resist twist under load. It's a long block only - reuse your existing intake, EFI, and ignition - and '07-'16 Touring installs need a separate S&S oil line kit.
