Rainy Eyes is correct, Ares are notorious for using soft plastic in their tappets. I replaced two Ares tappets ordered direct from Ares for replacements and within a week they were destroyed
Do some research to make sure they aren't proprietary because a lot of what Ares makes is making upgrades and repair a major pita
Consider yourself lucky if aftermarket parts fit and it isn't crumbling apart while you work on it
If you breath on some Ares pieces they crumble like a Man side-eyeing Medusa on a switch back
Can´t sleep. Clowns will eat me!
