Upgrade your drivetrain with the Cuobim SCX30 Differential Worm Gear Set, designed for 1/30 Axial SCX30 RC rock crawlers. These CNC one-piece hardened steel differential gears provide smoother power transfer, stronger torque handling, and long-lasting durability compared to stock gears.
This SCX30 Differential Worm Gear upgrade lets you tune crawling performance with different gear ratios. Using overdrive in the front or underdrive in the rear pulls the vehicle faster at the front axle, helping your crawler climb obstacles more easily and reduce rollover risk on steep terrain.
Gear Ratio Options (based on stock 2T/16T):
2T/12T – Increase speed approx 33%
2T/13T – Increase speed approx 23%
2T/14T – Increase speed approx 14%
2T/16T – Same as original factory ratio, direct replacement
2T/18T – Decrease speed approx 11% for smoother low-speed control
Precision-machined for a direct steel gear replacement, this set fits Ford Bronco AXI-2048, Jeep Wrangler AXI-2261, and Chevrolet K10 AXI-2260. Installation is simple and precise, making it an ideal RC crawler drivetrain upgrade for better climbing power, improved control, and enhanced off-road performance.
If you're looking for reliable SCX30 RC crawler parts that boost torque delivery and stability on rocks and steep slopes, this SCX30 Differential Worm Gear Set is a must-have upgrade for your Axial SCX30.
