Solid Shifter Linkage U-Joint Trunnion Fit Subaru STI w/6 Speed Swap 2014 2015

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 2014 and 2015 model years. It connects the shifter linkage to the transmission, providing a stiff, wobble-free connection. This solid shifter linkage U-joint trunnion is engineered to enhance shift precision.

Overview

This solid shifter linkage U-joint trunnion is built for Subaru STI vehicles that have undergone a 6-speed swap, covering the 2014 and 2015 chassis. It replaces the factory rubber-mounted trunnion with a solid metal unit, providing a more direct connection in the shifter assembly. The part improves shift feel and accuracy for drivers with a 6-speed swap on their 2014 or 2015 Subaru STI.

Specs At A Glance

Good To Know

Q: Will this trunnion fit my standard 2014 Subaru STI transmission? A: This part is specifically designed for a 6-speed swap, so it will not fit the stock transmission linkage on a 2014 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.
