RPM have produced An A-arm design for the Associated SC10 4×4 that can handle the roughest and toughest abuse and still come back for more. Since strength and durability were primary design considerations, they focused on common breakage areas for strength upgrades. Hinge pin and cross holes such as shock mounts and anti-sway bar holes have been beefed up for some much-needed muscle. The structure of the A-arms is also dramatically different than the stock design, which not only helps with the strength and sturdiness of the overall design, it also helps contribute to a stronger, less flexible design than the stock A-arms. All this strength and at a weight that is virtually identical to stock Associated A-arms.
