I noticed the Pro4 SC10 (and, by extension the MT10) has arm mounts and insert pills that suggest a possibility for adjustment. Looking at the basic setup I found no setup sheet but I measured -2.2 degrees of anti-squat (equal ride height front and rear). That’s pro-squat really, and goes against every setup guide I know of!
All the other Associated off road vehicles have +1 to +2 degrees of anti-squat as the standard setup. (Yeah I know it’s a rebranded Helion but still.) I can’t mention a single race-worthy truck or buggy from the last 30 years with pro-squat rear suspension.
So let’s fix that. I removed the rear skid plate and turned the C-block upside down. It would interfere with the skid plate so that has to be addressed, but the fronts of the hinge pins were elevated quite a bit. Great!
My first thought was to file the arm mount until the skid plate fits back on and that’s what I did. However, I think filing relief cuts to the skid plate itself would be a better idea in order to retain full strength of the arm mount.
With the parts back together I measured a healthy +1.2 degrees on anti-squat. The truck handles a lot better now: has more grip when accelerating, doesn’t slap the chassis so easily, and I can soften the rear springs for more overall grip.
This mod costs nothing, doesn’t require special skills or tools, and is reversible in case you don’t like it.
