Description:

IAG Comfort Series 55A Transmission Mount -- 2002-2021 WRX / 2004-2008 Forester XT / 2005-2009 Legacy GT (5-Speed)

Upgraded Transmission Mount for Daily Driver Comfort
The IAG Comfort Series Transmission Mount is fitted with 55A durometer bushings in a CNC-machined billet aluminum body, delivering noticeably reduced drivetrain movement over a worn factory mount while prioritizing street comfort. Ideal for daily drivers and street cars where NVH management matters as much as performance. Compatible with 2002-2021 WRX, 2005-2009 Legacy GT, and 2004-2008 Forester XT models equipped with 5-speed transmissions.

Why Upgrade From OEM
Over time the OEM rubber mount softens and deteriorates, allowing more drivetrain movement than factory intended. The IAG 55A Comfort mount restores stable drivetrain control with minimal NVH penalty -- ideal for daily-driven WRX and STI builds.

Modular Bushing System
IAG's mounts use interchangeable bushings -- swap to a softer or stiffer durometer by purchasing the bushing kit separately.

Flush-Mount Hardware
IAG's flush-mount hardware design means the mount can be installed without disassembly. The four included Allen socket head screws provide all the hardware needed.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available -- and the engineering shows.

The RallySport Take

The IAG Comfort Series mount is the one to specify for a daily driven WRX or STI where ride quality matters. The 55A bushing delivers better drivetrain control than a worn OEM mount without adding harshness to the daily commute.
