Engine Motor Mount Set for Acura TSX (2009-2011) 2.4L Automatic

Heavy-Duty Engine and Transmission Mount Set for 2009-2011 Acura TSX (CU2)

What it Does: The 5-piece engine and transmission mount set anchors the drivetrain to the subframe on the 2009-2011 Acura TSX 2.4L, eliminating excessive engine pitch, restoring shift crispness, and damping harmonic idle vibrations transferred into the passenger cabin.

The Stock Acura TSX Mount Failure

Factory mounts on the second-generation CU2 TSX degrade rapidly under repeated thermal cycling and engine torque loading. The OEM right-side hydraulic mount (50820-TA0-A01) consistently experiences internal diaphragm tears, leaking its damping fluid and collapsing against its metal bracket. Simultaneously, the rubber isolators in the front (50830-TA0-A01) and rear (50810-TA0-A01) torque struts fatigue, dry-rot, and tear. This rubber breakdown allows significant powertrain movement, resulting in noticeable driveline lash, delayed throttle response, harsh gear engagement, and heavy cabin reverberation at stoplights.

The Engineering Solution

This 5-piece direct-fit set eliminates drivetrain movement by utilizing durable, high-density elastomeric rubber bonded to heavy-gauge stamped steel mounting brackets. The right-hand hydraulic unit features a sealed damping fluid chamber specifically tuned to absorb the natural second-order vibrations of the 2.4L K24Z3 i-VTEC engine. Restoring both upper (50870-TA0-A01) and lower (50850-TA0-A01) transmission mount supports stabilizes transaxle pitch, keeping CV axle operating angles true and eliminating excess load on the transmission casing under load.
