New part for the backend - FF RSB

Just wanted to share that I finally got my RSB from Firm Feel
9B83343F-6AD1-4C4E-87BE-8AD5F6426B85.jpeg

Can’t wait to install it. Although I have to ask… do we absolutely need grade 8 bolts for the shackles? new U bolts too?. Also do I need to get an alignment after installing the RSB?

anyone have experience installing FF RSB?
