yes it will chip off, and i have had issuses with those swingers cracking and breaking from jumping, but alot of members have them and have had no issuses
i realized why they started buliding them out of aluminum today, i swear this swing arm weighs 50 pounds.
Dude build you own. or even get a welder to weld some peices in there either way its gonan be cheaper then buying one, and stronger.
