Description Feature: Extremely compact and lightweight 57g / 2.01oz. Dimensions (mm): 30L × 56.5W × 37.5H (Length excludes output shafts) Designed for motor forward mounting (Right Motor Version). Mounting is accomplished by two M3 tapped holes, 23mm center to center (not angled). Comes with an aluminum slidable shim based on the Axial 3 gear type transmission mounting holes. High strength carbon fiber case. CNC aluminum motor mount and transmission brace. Heat treated alloy steel gears. Grade 5 Titanium output shafts. Fits 48 Pitch pinions from 9T to 17T(Not Included) Transmission Ratio: 3.67:1 Front Output 3.67:1 Left Rear Output 4.42:1 Right Rear Output 18.6% overdrive (both outputs spin same direction, so no need for flipped ring gears). 28% overdrive when using: Rear underdrive gear set (33T/8T) + Front stock gear set (30T/8T). 38% overdrive when using: Rear underdrive gear set (33T/8T) + Front overdrive gear set (27T/8T). Included: 1x Overdrive Transmission 1x Slidable Shim 1x Hardware Set

• Ultra-Compact and Featherweight Performance:Weighing only 57g (2.01oz), this transmission delivers exceptional power efficiency without unnecessary bulk. The compact footprint (30 × 56.5 × 37.5mm) ensures a lower center of gravity, ideal for competitive LCG crawler builds where weight savings and space optimization are critical.
• Precision-Engineered Carbon Fiber and Alloy Hybrid Construction:Built with a high-strength carbon fiber case, CNC-machined aluminum motor mount, and heat-treated alloy steel gears, this gearbox provides an unbeatable balance of strength, durability, and lightweight performance—engineered for demanding rock crawling conditions.
• Advanced Overdrive Gear Ratios for Enhanced Crawling Control:Delivers 18.6% base overdrive, improving steering precision and climbing stability by synchronizing front and rear wheel speeds. Optional configurations enable 28% or 38% overdrive using different gear sets, allowing expert tuners to fine-tune traction and control for various terrains.
• Titanium Output Shafts for Ultimate Efficiency and Durability:Equipped with Grade 5 titanium output shafts, this transmission offers superior wear resistance, reduced drivetrain flex, and optimal power transfer efficiency—perfect for competition-level rock crawlers that demand maximum performance and reliability.
• Versatile Mounting and Compatibility Design:Designed for motor-forward setups (Right Motor Version) with M3 mounting holes spaced 23mm apart, it easily integrates with Axial 3-gear transmission patterns and fits 48-pitch pinions (9T–17T). Includes an aluminum slidable shim and full hardware set for seamless installation and fine-tuning.
