    Creaking in rear suspension with mono balls

    Hi guys,
    In your comp coupes, do you hear a lot of creaking noises in the rear suspension?
    I have done the complete mono-balls conversion on my 2013 track car, love them the car handles great. They are creaking pretty bad, I can't remember if it's always been this loud since I installed them 2-3 track events ago. Everything is greased and tight, nothing is lose. Is this normal?

    Thanks.

    I tried the ViperPartsUSA billet mounts but I would have had to have my shocks length changed and didn't really want to get into all that for now, so back to stock.
    You?

    If you have the OEM lower shock mounts that could be the source of your noises. Viper parts USA makes a Delrin replacement for the stock shock mount that I am currently running without issues. We have been seeing failures of the OE lower mounts which gets exacerbated by higher than stock spring rates.

    My mono ball suspension is as quiet as a church mouse.

    Did you have to change the length of your shocks?

    I am running stock length MCS on my car. The VPUSA delrin mounts use the same steel housing as the OE bushing and the delrin insert takes the place of the rubber.

    You were right! My rear lower OEM shock mounts are cracked. I ordered the Delrin replacement bushings, are you saying that will help them last longer? Otherwise seems like I'll be breaking these every weekend...

    It really seems that the cars with heavier sprung suspensions pound out the rubber in that lower bushing. Chrysler has been using that same style since 2003.
