The SC10B, SC10.2 & T4.2FT have new, gull-wing style front A-arms that have had RPM customers contacting us for help. This new shape has been less durable than RPM customers require. The RPM A-arm design eliminates the gull-wing shape in favor of a straight A-arm design with a lowered shock mount position (the shock slips through the center of the A-arm perfectly) to retain stock suspension geometry, yet the straight A-arm style improves durability immensely. To help improve overall durability, we also focused our attention on the hinge pin retainers. The stock set-up uses a small screw placed next to the hinge pin, relying on the head of the screw to keep the hinge pin in place. This screw hole adds a weak spot on the A-arms. Our A-arms eliminate that screw in favor of an in-line screw to keep the hinge pin in place thus increasing the durability of our A-arms even further.
