( Manufacturer Part Number: C4AZ-7107-D ), ( Type: 2 Synchronizer Blocking Rings )
The Ford C4Az-7107-D transmission synchronizer blocking rings are essential components designed for manual transmissions used in various classic Ford models, including the Mustang, Fairlane, and Falcon produced between 1965 and 1972. These high-quality synchronizer rings are specifically engineered to ensure smooth and efficient shifting between gears, making them an excellent investment for enthusiasts and restorers.
These Ford synchronizer blocking rings are meticulously manufactured to meet original equipment specifications, ensuring they function as intended in your classic Ford vehicle. The precision machining process used results in rings that exhibit exceptional accuracy and fit, allowing a perfect match to your existing transmission synchros. This hand-picked attention to detail cuts down on the hassle of having to replace an entire assembly when only a single part requires attention.
Each ring comes in a set, typically featuring three separate rings - first, second, and third gear synchros. They are precision-production knurled ring type synchronizer blocks for Ford C4 transmissions. These hardware pieces attach to the side gear engagement knobs, improving the engaging quality as the gears mesh during a shift. The increased contact area between the ring and the gear teeth makes for a seamless and quiet synchronization experience.
Moreover, the surface of the synchronizer rings displays an X-patterned design to interface with the engagement teeth on your gear train. When pressed against the teeth during the shifting process, they help to engage the gears more gradually and evenly, reducing wear and tear on the gear teeth and transmission components. Ultimately, these synchronizer blocking rings are crafted to deliver optimal performance, durability, and ease of shifting for your classic Ford transmission.
