Solid Shifter Linkage U-Joint Trunnion for Subaru STI
This solid shifter linkage U-joint trunnion is a direct replacement component designed for Subaru STI models equipped with a 6-speed swap, specifically for the 2006 and 2007 model years. It serves to connect the shifter linkage, ensuring precise and reliable gear engagement. This solid shifter linkage U-joint trunnion eliminates the slop found in factory rubber bushings.
Overview
This solid shifter linkage U-joint trunnion is built for Subaru STI vehicles that have undergone a 6-speed swap, covering the 2006 and 2007 chassis. It replaces the factory rubber-mounted trunnion with a solid metal unit, providing a more direct connection in the shifter assembly.

Good To Know
Q: Will this trunnion fit my standard 2006 Subaru STI transmission? A: This part is specifically designed for a 6-speed swap, so it will not fit the stock 5-speed transmission linkage on a 2006 STI. It is intended for applications where the 6-speed gearbox has been installed.
Q: What is the main benefit of a solid trunnion over a rubber one? A: A solid trunnion removes the compliance of the factory rubber piece, which transmits more of the shifter movement directly to the transmission. This results in a more precise and positive shift feel, especially under hard driving.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
