My front upper arms broken what you suggest plastic or aluminium - any experience? Thanks.

For arms plastic is the way to go. Aluminum is stronger but then the next weakest part is gonna break instead in a crash. Plastic can bend slightly, is lighter, and cheaper.

What he said!
If you take aluminium.. Youre gonna break the diff bulkhead.. Price wise.. About the same.. But loads more work to replace that over an a-arm

Never aluminum arms on anything that gets driven.

Back before the Covid stuff hit the fan I emailed rpm about k8s arms. They said they had a k8s and were developing them. Hopefully they are not delayed too much. I’ve been breaking less arms lately but probably broke 5 or so all together. Once they have those I would definitely get them.

Aluminum arms are for shelf queens! ?

thanks for feedback guys. It is better to get lots of plastic backups for drive train & chassis parts..
