NSA aluminum vs steel clevis?
We purchased our NSA Ready Brute in 2017 and it came with aluminum clevises. I noticed that the new ones come with steel clevises. The website says:
"Starting in 2020, All NSA aluminum tow bars and steel tow bars require a STEEL clevis: (Ready Brute Elite 2, Ready Brute 2, Hercules, Atlas)
All NSA tow bars manufactured prior to 2020 require an aluminum clevis."
Does anyone here know why, exactly, the older ones "require" aluminum and the newer ones require steel? It sort of implies that the older ones should not be fitted with steel. In this applications wouldn't steel be preferable?
