Frequently Asked QuestionsEverything you need to know
What does the Traxxas Underdrive Machined Differential Ring and Pinion Gear Set do?
The Traxxas Underdrive Machined Differential Ring and Pinion Gear Set alters the drive gear ratio to reduce axle speed relative to motor output. This improves climbing traction, minimizes chassis torque twist, and delivers tighter steering response on technical terrain.
Is the Traxxas Underdrive Machined Differential Ring and Pinion Gear Set compatible with my Traxxas TRX-4?
Yes, this underdrive gear set is a direct fit replacement compatible with all standard Traxxas TRX-4 and Traxxas TRX-6 scale crawler models.
Why should I upgrade to a machined steel Traxxas Underdrive Differential Gear Set?
Machined steel gears offer significantly higher strength and durability compared to standard cast gears, preventing wear and gear stripping under high load from powerful brushless motor systems.
