Description

• Hardened 45# Steel Construction for Long-Term Durability:Manufactured from high-strength 45# steel and treated with a black oxide hardening process, these gears offer exceptional wear resistance, corrosion protection, and reliable performance under continuous crawling loads
• Precision Worm Gear Design for Superior Crawling Control:Utilizing a worm and wheel differential system in both front and rear axles, this gear set delivers smoother power transfer, improved low-speed modulation, and added ground clearance essential for tackling rocks, roots, and uneven trail obstacles.
• High-Accuracy Machining for Smooth & Quiet Operation:CNC precision manufacturing minimizes gear lash, vibration, and drivetrain noise while reducing long-term wear resulting in more efficient power delivery and consistent drivetrain performance.
• Tunable Performance with Overdrive & Underdrive Options:Customize your SCX30s driving dynamics with multiple gear choices (12T / 13T / 14T / 16T / 18T). Overdrive setups increase forward speed up to 33% for improved front pull and steering control, while underdrive gearing enhances climbing torque and reduces rollover risk on steep technical terrain.
• Direct Upgrade for Axial SCX30 Platforms:Designed as a drop-in replacement for stock gears, this set fits both front and rear axles on Axial SCX30 models including the Ford Bronco, Chevrolet K10, and Jeep Wrangler JLU making it an easy yet impactful performance upgrade (2 sets recommended for full vehicle tuning).
