Phadt has "TWO" Bushings. One is part number PFA 1410105 which is the "Street Bushing". They also have part number PFA 1410122, which is their "Racing Bushing" which is very hard and not recommended on the street.

Which one do you have? I found a lot of folks don't know that they carry two, and their website doesn't do a good job of getting you there, but you can check with Apex as I just ordered the 105 "Street Bushings" and they do carry both.

I would sure like to know which ones you have before I install mine. Hope this helps.

My vehicle is so loud now I won't hear or notice the additional noise from any busshing upgrades I do. LOL
I want the hardest best performing bushings I can get my hands on, IMO don't drive a racecar. If you want a girls car buy a Mercedes and call it a day.
