S&S Cycle 910-0277 4-1/8" Bore Cylinder & Piston Kit for T111 Engines Wrinkle Black

This complete cylinder and piston kit is designed to replace the cylinders and pistons on early production S&S T111 engines. Engineered for 4-1/8" stroke flywheels, this kit delivers 111 cubic inch displacement with premium components throughout.

Complete Kit Includes:

• S&S 4-1/8" bore cylinders with durable wrinkle black powder coat finish
• Forged flat-topped pistons designed for use with S&S Super Stock cylinder heads
• Piston rings and wrist pins
• Head and base gaskets

Technical Specifications:

• Bore: 4-1/8 inches
• Stroke: 4.763 inches (designed for 4-1/8" stroke flywheels)
• Displacement: 111 cubic inches
• Finish: Wrinkle black powder coat
• Cylinder design: 11-fin configuration

The cylinders are precision-machined with the S&S bolt pattern and are specifically intended for use in S&S crankcases used in early S&S T111 engines. For optimal performance, this kit should be paired with appropriate camshafts, performance air cleaner, performance exhaust system, and proper fuel system tuning. EFI-equipped engines will require tuning with a flash tuner such as the Dynojet Power Vision for 2001-2016 engines with Delphi EFI systems.
