2015+ WRX & STi Rear Differential Mount Bushing Inserts


Precision machined 6061 Aluminum.

Anodized for a durable and aesthetic finish.

When Subaru released their 2015 WRX & STi, they used soft rubber bushings to connect the differential to the rear crossmember.

These inserts will lock down and tighten your differential to the frame to reduce movement and any loss of mechanical energy. 

No removal of OEM parts, simply add these inserts to lock in the Diff!

These also reduce the jerky motion experienced when letting off throttle due to excess play of the OEM soft rubber bushings.

If you want more control and better upshifting, you need these.

Fits 2015, 2016, 2017, 2018, 2019, 2020, and 2021 Subaru WRX and STi
