This is an optional 1UP Racing RC10B7/B6 "Stand-Up" Aluminum Idler Gear.
We are excited to introduce our new 1up Racing Aluminum Idler Gears for the Team Associated RC10B7 & B7D, made in collaboration with our partners at TRION.
Precision-machined from premium-quality Japanese Aluminum, these gears will greatly increase the durability of your AE B7 transmission. Friction is kept at a minimum for a free-rolling drivetrain that provides smooth, quick acceleration. Add 1up Racing Gold AW Grease to these hard anodized gears for unmatched longevity, especially critical in the high-powered modified 2wd class.
