Cobb 08-21 Subaru WRX & STI/2018 Type RA/2019 S209 Transmission Crossmember Isolator Kit
The COBB Transmission Crossmember Isolator Kit replaces factory rubber bushings on 2008-2021 Subaru WRX and STI models, including the 2018 Type RA and 2019 S209, with 95A durometer polyurethane bushings. This upgrade eliminates driveline slop for crisper shifts and more direct power transfer. Drivers notice immediate improvements in shifting precision and reduced cabin vibrations during aggressive driving.
Key Features
- 95A Polyurethane Bushings: Firm durometer material outlasts stock rubber, maintaining shape under high torque loads for consistent performance.
- Driveline Slack Reduction: Tightens transmission crossmember connection, delivering precise gear engagement and smoother power delivery.
- NVH Control: Dampens road and engine vibrations without isolating the chassis, keeping driver connected to the road.
- Factory Alignment Retained: Precision-machined spacers ensure crossmember stays in OEM position for no alignment issues.
- Laser-Etched Branding: COBB logo on bushings for authentic identification and quality assurance.
Product Notes
- Complete kit includes two polyurethane bushings, isolator spacers, and all hardware for plug-and-play install.
- Engineered and manufactured in the USA for Subaru-specific drivetrain demands.
- Small package design allows easy storage and transport.
Installation Notes
- Professional installation recommended.
- Bolt-on install completes in 20-30 minutes with basic hand tools; jack access required to drop crossmember.
- Reuses factory mounting hardware; no drilling or modifications needed.
