About this item

  • 【High-Precision CNC Machining】This complete transmission gearbox adopts CNC-machined aluminum alloy housing, offering excellent structural strength and impact resistance. It resists cracking and deformation during intense rock crawling, delivering stable long-term performance under tough off-road environments.
  • 【Optimized 21:1 Gear Reduction】Built with precision metal gear set with 21:1 reduction ratio, effectively increase torque output. Greatly upgrade the climbing capability of your Ascent-18, enabling the vehicle to tackle steep slopes, gravel roads and rugged terrain with stronger traction and better throttle control.
  • 【Direct Bolt-on Upgrade for Ascent-18】Perfect upgrade part for 1/18 Ascent-18 RC crawler. Matches original mounting positions and transmission structure, plug-and-play installation without extra cutting or modification. Great choice for RC enthusiasts to upgrade vehicle durability and power efficiency.
  • 【Heavy-Duty Metal Gear Structure】Hardened metal gears plus aluminum alloy housing replace fragile plastic stock parts. Lower abrasion, quieter operation and smoother power transmission. Maintain consistent performance even under long-time rough trail driving and high-load use.
  • 【Modular Design for Easy Servicing】Detachable split structure allows independent disassembly. You can separately swap gears, bearings and wearing parts conveniently instead of replacing the whole assembly, greatly lowering maintenance time and spare part costs.

    I found the replacement parts I needed for my RC truck without having to search through unrelated products. The categories were easy to understand, and the new wheels and suspension parts worked well for my weekend build.

    I am still fairly new to RC cars, so I appreciated how clearly the products were grouped. It was easy to compare chargers, connectors, and maintenance supplies for my first off-road vehicle.
