I think your Infraction is 3s? so my applications won't necessarily work directly for you, but hopefully will point you in the right direction. I turned a 6s Infraction into an off-road beast & I've been ripping with it for a couple weeks now. Had to go to Kraton6s arms, links, axles etc & use hub extenders to clear the body (XO-1) that I was dead set on using. Not sure if I'll keep it like this because the turning radius is terrible & it drives just ok. https://www.arrmaforum.com/threads/off-road-infraction.61883/
Good luck!!
