Increased Transmission Durability

The synchronizer rings must be replaced since they have a friction lining that will eventually wear out. It’s labor-intensive to gain access to the internals of a transmission. The unit has to be removed, disassembled, reassembled, and re-installed. As such, it’s always good practice to replace all wear items. The bronze shift fork pads in this kit replace the weaker plastic ones, providing increased durability. The replacement synchronizer rings are a revised carbon-hybrid version, which only came in the C7 Corvettes from the factory. The original style of synchro ring is sintered metallic, and those are prone to overheating. With the carbon-hybrid style, the chance of overheating is drastically reduced.
