Technical Performance
The LCXU transmission represents a significant engineering advancement for 1/10 scale rock crawlers in the UK and worldwide. All internal gears are constructed from metal for exceptional strength and durability, whilst the transmission features a complete set of ball bearings throughout the drivetrain, reducing friction and ensuring smooth, efficient power delivery. This bearing-equipped design translates directly to longer runtime from each battery charge and extended component lifespan, meaning you spend more time crawling on the rocks and less time in the workshop performing maintenance. The transmission housing provided in this kit is engineered to precise tolerances, ensuring that all dig parts fit perfectly without shimming or modification. The servo saver system, featuring a choice of 20T or 25T adapters depending on your servo selection, protects your steering linkage from impact damage whilst maintaining responsive control input. The included spring retainer with 225 lbs/in rating provides the correct resistance for smooth servo saver operation. The high-clearance spur cover design prevents trail debris from lodging around the spur gear whilst maintaining adequate ground clearance for extreme rock crawling. The dig lock-out mechanism provides a simple, reliable way to disable the DIG feature mechanically without electrical intervention, making it ideal for adjusting your crawler's behaviour between different types of terrain or driving styles.

Compatibility and Application
This transmission case and dig parts kit is designed exclusively for the Axial LCXU transmission system and is confirmed compatible with the Axial SCX10 III 1/10 rock crawler platform. The kit integrates seamlessly with vehicles built on the SCX10 III 4WD Rock Crawler Builder's Kit (AXI-2755) and serves as both a replacement transmission assembly and an upgrade option for existing SCX10 III builds. The Basecamp Builders Kit V2 specification ensures compatibility with that particular chassis generation. If you are upgrading from an earlier SCX10 III transmission design, this kit provides all necessary components to transition to the modern LCXU system, which offers superior durability, smoother operation and the added flexibility of optional dig conversion without requiring a complete drivetrain replacement.
Frequently Asked Questions
- What is DIG and why would I want it on my RC crawler? — DIG stands for Differential Inter-axle Gear, a servo-actuated feature that allows you to lock the rear wheels independently from the front differential. This creates a dramatic improvement in turning radius on tight, technical terrain, enabling faster pivots around obstacles and sharper turns where a standard open differential would cause the inside wheels to slip. For rock crawling in confined spaces or technical sections, DIG conversion is increasingly recognised as essential equipment that separates capable crawlers from truly competitive ones.
- Is the DIG feature mandatory, or can I run this transmission in standard 4WD mode? — The DIG feature is completely optional. The transmission can be externally locked in standard 4WD mode and used without any servo actuation or DIG components. A dig lock-out mechanism is included in the kit, allowing you to disable the DIG feature mechanically if desired, meaning you have the flexibility to add dig capability later without any modification to your existing setup.
- What servos are compatible with this dig parts kit? — The kit includes two servo saver adapters: a 20T adapter for SX107 servos and a 25T adapter for 99 Micro servos. This provides excellent flexibility for servo selection and allows you to choose based on availability, torque requirements and personal preference. The servo saver system protects your servo from impact damage during aggressive crawling.
- What is the servo saver spring rating included in this kit? — The dig parts kit includes a servo saver spring rated at 225 lbs/in, which provides the correct resistance for reliable dig operation whilst protecting your servo from the shock loads encountered during aggressive pivot turns and rock obstacles.
- Is this kit suitable for beginners, or is dig conversion advanced? — Dig installation requires mechanical assembly knowledge and is best suited to intermediate to advanced builders who are comfortable disassembling and reassembling transmission components. However, the kit is designed to work with the SCX10 III Builder's Kit, which is an entry-level platform for learning RC construction. You can start with standard 4WD operation and upgrade to DIG capability later as your skills progress.
- Can I upgrade my existing SCX10 III transmission to use the LCXU system? — Yes, this kit is designed as both a replacement transmission assembly and an upgrade option for existing SCX10 III builds. If you currently own an SCX10 III with an earlier transmission design, this kit allows you to transition to the modern LCXU system, gaining access to optional DIG conversion and all the durability improvements of the newer design.
- What makes the LCXU transmission better than earlier designs? — The LCXU transmission features all-metal internal gears for superior strength and a complete set of ball bearings throughout the drivetrain, reducing friction and improving efficiency. This translates to longer runtime from each battery, smoother power delivery, less maintenance and extended component lifespan. Additionally, the LCXU design makes it easy to switch between standard straight axles and portal axles with just a single gear change, providing flexibility for different crawling styles.
- Does this kit come with everything I need to convert to DIG? — Yes, the kit includes all components necessary for dig conversion: servo mounts, shifter linkage, servo saver components, dig lock-out mechanism and the dig case itself. You will need to supply a suitable servo (compatible with either the 20T or 25T servo saver adapters) and have the mechanical skill to assemble the system, but all transmission-specific components are included.
- What is included in terms of high-clearance design? — The kit includes a high-clearance spur cover specifically designed for the SCX10 III LCXU configuration. This protects the spur gear from trail debris whilst maintaining the ground clearance essential for rock crawling, preventing rocks and obstacles from catching on the drive components.
