STI Transmission Crossmember Uprated Rubber Mount Set

ST410224S030 – STI Cross Member Cushion Rubber Set

Upgrade the rigidity of your drivetrain mounting with this genuine STI Cross Member Cushion Rubber Set. Designed for the power-unit cross member, it replaces the factory bushings with harder STI-spec rubber to reduce flex and sharpen response.

Key Benefits

• Firmer engine and transmission support

• Improved throttle and shift feel

• Durable STI-grade rubber construction

• Direct replacement for OEM mount cushions

Fitment

Suitable for Subaru models that use part number ST410224S030 (commonly GD/GG-chassis WRX/STI). Always confirm compatibility with your vehicle.

Notes

The stiffer rubber increases precision but may introduce additional cabin vibration—normal for performance-focused mounts.
