WOW is all I have to say. I have had the RK Lower mount, and upper insert for quite some time....I've gotten used to how my motor moved, which wasn't much. Just got my new motor installed with the TTR trans bushings...and WOW. My motor didn't move an INCH. vibrations are same as before, I see NO negative side effect to this product other then a little tough to install into the mount, but nothing out of the ordinary of installing any other bushing. Would I buy again? ABSOLUTELY! A+ PRODUCT!!!

I didnt really notice much of a gain from the trans bushings. most of my gains came from his upper and lower mount. never the less, very good product.
