Installed new RPM B4 front arms
Installed new RPM B4 front arms
Installed a set of RPM B4 arms on my B4.1. Haven't had a chance to run them, but def beefy compared to the stock front arms!

That's too bad, I kind of like the bling of the aluminum end cap.

Re: Installed new RPM B4 front arms
I wonder if that will cause front hinge block failures without the hinge pin brace?

Re: Installed new RPM B4 front arms
So far so good!! The car's handling behavior seems to be the same and consistent. I do admit that I drive a bit more aggressively now not worrying about breaking the front arms. Now I just hope they come out with a set of rear arms and maybe some shock towers.
flipwils11, I do agree that it looks more plain without out the aluminum blue upfront.
clm, the arms come with a new beefier hinge pin bulkhead. The directions say you can only use the provided one and the stock or aftermarket aluminum one's won't work. The setup is the same that RPM uses on SC10's and T4's. I have them on both of mine and after much abuse I've never had any problems.
Here's a pic of my B4 next to my T4, and a lone pic of my Sc10 all with RPM arms and RPM bulkheads.

Re: Installed new RPM B4 front arms
I had these arms on a t4 and they took some of the hardest hits i have ever seen with no issues great product recommend for anyone with an "aggresive" driving style
Re: Installed new RPM B4 front arms
I had them on my T4 and hated them. ON a hard packed high traction Clay track they allowed a little too much movement in the front end. You could see the front end shake a little bit landing on jumps. However on a hard packed dirt track with a little moisture they were just fine. Too bad we run on the Clay track 9 months out of the year.
But at least with the Rpm arms on the T4 you could finish every race. With the Factory Team arms they would break if you over shot the downside of a jump even if you landed flat.

Re: Installed new RPM B4 front arms
dont buy Factory Team arms if your worried about breaking arms. they seem to snap where stock bends .. i hear the "feel" is not the same on the track but i rather have less of a chance snapping arms. same goes for turnbuckles, i always raced steel turnbuckles on my rc10t . other guys would snap ti turnbuckles and be out of the race . id bend the steel bad but id be able to finish the race. my big issue is what happens if you bend a rpm pin .. do they sell just the pins? (oh and i love the washers on the shock tower great idea)vwjuice wrote:I had them on my T4 and hated them.

Re: Installed new RPM B4 front arms
The stock arms definitely don't feel the same on the track. I'm just a club racer at best and I could tell the difference. They were way too inconsistent. I sold both the T4 and B4. I was irritated that I spent hundres of dollars for the kit with all the hop ups just to have it break more than an rtr. It was really frustrating.
My rpm T4 arms used the stock pins so you shouldn't need any new ones.

Re: Installed new RPM B4 front arms
When I got the arms it came with some new screws which are a lot bigger than the stock ones and it reused the stock pins. The screws that Rpm includes are a lot nicer than the stockers since they use a larger head and it's easier to get them out.

Re: Installed new RPM B4 front arms
The rpm arms were great on a loose loamy track. No problems whatsoever. On a hard packed Clay I just didn't like the way the truck drove and the rtr arms were even worse. It was a shame cuase the truck was unstoppable with the FT arms until they broke anyway.
