Hello,
I have heard of other brands using larger diameter tubing which lead to tire rubbing with wider tires. We use 1.250" DOM tubing which is not larger than the factory arms and we haven't had any tire clearance issues.
If I can help anymore please ask. Also this item is on sale right now too![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Thank you!

Do your 1.25" arms rub on the stock 18" Impala SS tires?

I wrote an article many years ago 07-08 about this:
Basically the stock tubes are .750" and offset... The modification required is quite simple as to remove and elongate to mounting holes in the forward trailing arm mount bracket and if required to install up to 3 galvanised washers on the rear mount point as long as the attach bolt is in saftie (minimum 3 threads showing/ protruding from nut) when installed.
There are some great pictures located in this thread:
