Whiteline 11-14 Ford Mustang GT / 12-13 Boss / 15 V6, Ecoboost, GT Gearbox - Mount Insert Bushing

If you're looking to tighten up the feel of your shifter when rowing through the gears in your 2010-2025 Ford Mustang, this gearbox mount insert from Whiteline is a solid option. It works by slipping into the factory gearbox mount, filling in the voids and reducing unwanted movement. This means less slop and a more direct connection between your shifter and the transmission.

Whiteline uses a tough synthetic elastomer for this insert, which is built to stand up to oil, grease, ozone, and general weathering. The design is specially bonded for strength, which is important because this mount takes a lot of load, especially when you're shifting hard. It's designed to work with your original factory mount, making it a straightforward way to get an improved shift feel without a full replacement.

You'll find an installation guide included, which walks you through the process. This is a popular way to get a more precise and satisfying shift experience in your Mustang.
