Kartboy Rear Diff Outrigger Bushings - Hard Subaru WRX / STI 2002-2007

Part #: KB-003-Diff-H. These Kartboy Rear Differential Outrigger Bushings, designed for 2002 - 2007 WRX and STi models, are a game - changer. Made from durable urethane in the USA, they eliminate the excessive play of soft stock rear differential bushings during hard acceleration and throttle changes. Say goodbye to the infamous Subaru 'clunk' after installation.

Using these Kartboy rear diff outrigger bushings is straightforward. Just replace your old, soft stock bushings with these new ones. When installing, make sure all parts are clean and properly aligned. As for maintenance, there's not much you need to do. Check them occasionally for any signs of wear or damage. If you notice the 'clunk' sound coming back, it might be time to give them a closer look. And remember, since they're made of urethane, they're built to last, but gentle handling during installation will ensure their long - term performance.
