Installing the a-arms is really easy. They are direct fit, you can install then in a hour. When I installed the hinge pins and pivot balls I noticed that they were more difficult to screw than with the stock plastic, it’s sign that they will never come loose.
I tested then in different situations. Because the lower shocks mounting holes are not located exactly like the the stock a-arm, the suspension geometry is a bit altered. At the track my Monster GT was a bit lower than normal, it’s a good thing for racing, this lower the truck’s CG and make it more stable. This is when I bashed my Monster GT that I really tested the new a-arms. I hit a pole at 30-35 MPH, the truck stopped instantly. I ran to see what was broken but nothing was cracked or bent, just a scratch on the a-arm. I’m sure that if those a-arms were aluminum, they will have bent or broke.
I can attest that RPM products are tough, I used them for many years on my RC10GT and they will outlast any expensive aluminum parts.
If you need more strength, RPM offers hubs carriers with oversized bearing. Now, I just wonder why RPM doesn’t offer shock towers for the Monster GT….
