||MUST HAVE PART FOR YOUR SLASH! Ok here is the truth: RPM Rear A-arms are the perfect combination of strength and durability, with just a touch of flexibility to save you when all other parts would have exploded like a parked smart car vs. a speeding 80,000lbs. semi truck. Yes they can break, but in a hammer like way: well used or a completely random fluke. I've never had any issues and they fit better then Mechanics Gloves. One note if you use the ProLine Chassis Saver you will need to trim down the extra mounting point, super easy with a quick pass of a Dremel.
Take it from someone who bashes his over-weight, over-powered slash almost daily.
