The Team Associated 92516 RC10B7 Rear Suspension Arms (81mm) are an optional geometry upgrade compared to the standard 78mm rear arms. While 78mm arms are the direct replacement, these 81mm arms are designed for racers looking to experiment with rear suspension geometry, stability, and tuning options.
⚠️ IMPORTANT – NOT A DIRECT BOLT-ON
These 81mm arms require additional parts to install correctly. This is not a simple swap, and is recommended for racers comfortable with setup changes.
