11% UNDERDRIVE
GEAR SET

Front Pulls. Rear Pushes. Better Climbing.

What Underdrive Does

Installed in the rear axle, this gear set makes the rear wheels turn about 11% slower than stock while the front axle stays the same. The front tires now turn slightly faster than the rear, so the front pulls while the rear pushes.

The result is a crawler that climbs ledges more confidently, keeps its nose tracking where you point it, and pulls itself around tight turns instead of plowing forward. Many competition drivers run this setup to get more out of every climb.

Why Run Underdrive on the Rear?

• Better climbing: the front tires pull up ledges and steep faces while the rear pushes behind them.
• Tighter turns: the faster front axle helps pull the truck around in tight technical sections.
• More control on descents: the slower rear helps keep the truck straight and settled going down.
• Moderate, proven ratio: 11% is a balanced setting that suits both competition and trail driving.
