Balance Shaft Delete Kit

The Massive Speed Balance Shaft Delete Kit (BSD Kit) is engineered to enhance engine responsiveness by eliminating the heavy balance shaft assembly, weighing in at an impressive 19 pounds. This modification reduces excessive engine rotational drag, allowing for quicker engine response and faster revving. The kit features a lightweight construction made from 6061 aluminum, manufactured in-house in the USA. This material choice ensures similar expansion rates to the OE aluminum block for a superior seal. The kit includes a Blue Flourosilicone O-ring for enhanced longevity compared to standard materials, a hardened fine pitch bolt and washer for maximum strength, and necessary Loctite. Full-color photographic installation instructions are provided, and installation can typically be completed within an hour using basic hand tools. This kit is specifically designed to block the oil feed to the balance shaft assembly in the Focus 2.3L Duratec engine. It is important to note that this kit is not compatible with naturally aspirated (NA) 2.0 Duratec/MZR engines or the 2.3 engine found in the Ranger / Mazda B2300, as these engines do not have a balance shaft from the factory. The kit fits a wide range of vehicles with compatible engines, including 2003-2024 2.3L and 2.5L NA Duratec engines found in the Fusion, Escape, Milan, and Focus. It also fits 2013-2024 2.0L and 2.3L Ecoboost engines in the Fusion, MKC, Corsair, Explorer, Escape, Focus ST, and RS. Additionally, it is compatible with 2005-2013 2.3L Mazda Turbo DISI engines (Mazdaspeed 3, 6, CX-7) and 2003-2013 MZR 2.3L and 2.5L engines (Mazda 3, 5, 6, CX-7).
