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

Whiteline's insert bushing goes into the factory gearbox mount on 2011-2026 Ford Mustang GT, V6, EcoBoost, and Bullitt models. It swaps in for the give built into that mount's factory rubber, and Whiteline says the result is a greatly improved shift feel and response.

Why Upgrade to a Positive Shift Kit Insert

Per Whiteline, here's what the insert changes:

• The insert fits directly into your factory gearbox mount.
• It cuts the compliance built into that mount, which comes heavily voided from the factory.
• That adds up to a shift feel that's greatly improved.
• Response improves right along with it.

Fitment Notes

Fits 2011-2026 Ford Mustang GT, V6 (2011-2017), EcoBoost (2015-2026), and Bullitt (2019-2020). Does not fit Dark Horse, GTD, Mach 1, GT500, GT350, or Boss 302. [VERIFY: the listing title references a 12-13 Boss application, but the canonical fitment data excludes Boss 302 entirely. Confirm which is correct before this goes live.]

Install and Honest Talk

This is a gearbox mount insert, not a full mount swap: it goes into the factory mount you already have. Whiteline built it to take the compliance out of that mount's heavily voided factory rubber, and less give at the mount means more of what happens at the gearbox reaches you through the shifter. That cuts both ways: expect more vibration and driveline feedback coming through the mount along with the tighter feel, the same tradeoff you get with any bushing or mount that reduces compliance.

Some oversize or heavy parts (long-tube exhausts, bumpers, full lift kits) go freight instead of parcel: free to a commercial address with a loading dock, and residential freight delivery carries an additional charge.

When it ships

Parts ship direct from the distributor warehouse that stocks them, so dispatch timing depends on the part, not on a single cutoff.

Report a short shipment or shipping damage within 5 business days of delivery. For a packing error, send us the date or package code printed on the label along with the part number so we can trace it with the warehouse.
