Idler Arm question

I installed a roller bearing idler arm from @BergmanAutoCraft on my Duster. It makes a significant, VERY noticeable difference. It removes quite a bit of resistance, especially when changing directions, like if you were turning right and then turned quickly back left.

Now, I have manual 16:1 steering with 275/35/18's up front, so anything that makes the steering lighter will be noticeable. But the roller bearing idler was a significant improvement over the standard idler arm, more than I expected for sure. I will be putting them on all my cars.
