RPM80182 Rear A-Arms Black E-Monster Jam, Rustler, Stampede Black

I'm building three Rustlers from scratch and I like that I can get RPM arms in different colors but each one I have purchased requires a fair bit of sanding to properly fit hop-up gear boxes. This shouldn't be a problem except that Traxxas control arms fit the hop-up gear box without any sanding. Seems like RPM could have done the same. Still, I'm happy with the results, just be ready to do some sanding to get the fit you need.

Fits perfectly and holding up really well

This will fit just as well as the stock Traxxas parts. They only have three holes for the shock towers to be moved around. DOES NOT come with the mounting gear so if you need the screws with it you will need to order them separately. The difference is strength and flexibility. RPM is the best maker of plastic parts in my opinion. Where others break RPM will flex and absorb the impact. This keeps you from breaking things. I cannot speak highly enough of these parts. I use these even with my aluminum parts as a "breaking joint" this is what is supposed to break when I get into too big of jumps and crashes. But my pede just keeps on trucking. Again this is what I will keep on using if I ever need to get new ones.

Great product, but be sure to also purchase some threadlock to keep the screws in place.

good quality seems tough..not sure how long they will last but so far so good with weekly use

These things are great. I used a set on my slash for 4 years and sold the thing before any RPM parts ever broke. Always have had a great experience with RPM

Very cost effective and they seem to be fairly well built. Time will tell as they are still plastic but seem to be a little thicker. I might purchase metal ones down the road but I couldn't pass these up for the price!

Can't beat RPM parts
