Description
The Setting Gear Set for AR Chassis is a gear-ratio upgrade part for Tamiya's AR Chassis, letting builders swap the stock final drive for one of five ratios to match a track's balance of straights and corners. A lower ratio such as 5:1 favours acceleration and hill climbs, while a higher ratio such as 3.5:1 favours top speed on long straights. The set also supplies a 1.4mm-diameter hollow lightweight prop shaft and a 620-size ball bearing, both direct replacements for the AR Chassis's stock parts.
- Gear ratios: 3.5:1, 3.7:1, 4:1, 4.2:1, 5:1
- 1.4mm-diameter hollow prop shaft included
- 620 ball bearing included
