Overview
The VITAVON Full Center Diff Case with 1.5mod 14/33T Spider Gears is a premium differential upgrade designed specifically for Traxxas X-MAXX and XRT 1/5 scale RC models. This is an essential component for serious RC enthusiasts in the UK who demand performance, reliability and ease of maintenance from their high-end 1/5 scale monster trucks. Whether you're a competitive racer, a weekend basher, or an experienced modeller looking to enhance your X-MAXX or XRT, this centre differential represents a significant upgrade over standard factory components.
Pre-assembled and factory-filled with 100K weight PMX-200 silicone oil, this differential set delivers instant readiness for high-performance RC operations. You won't need to spend hours tuning or assembling — simply unpack and install. The PMX-200 silicone oil is a professional-grade lubricant that ensures smooth operation across a wide range of driving conditions, from smooth tarmac to rough terrain. This ready-to-use approach is perfect for RC car enthusiasts in the UK who want to maximise track time rather than spend it on workshop maintenance.
What sets this VITAVON differential apart is its engineering excellence and compatibility guarantee. Engineered as a front-specific upgrade for the centre differential position, it is 100% compatible with both Traxxas X-MAXX and XRT 1/5 scale models, ensuring a precise drop-in fit without any modifications whatsoever. This level of compatibility is crucial when investing in upgrade parts for your ready to run RC truck, as poor fitment can lead to wasted time and expense.
Key Features
- Pre-assembled with factory-filled lubricant — The differential arrives completely assembled and filled with 100K weight PMX-200 silicone oil, meaning you can install it immediately without any preparation, setup or tuning required. This saves countless hours compared to purchasing individual components and assembling them yourself.
- 14/33T matched gear set — The 14-tooth and 33-tooth spider gears are pre-matched during manufacturing to ensure optimal power transfer, consistent performance, and longevity. This precision-matched pairing delivers superior torque distribution and more predictable handling characteristics than mismatched gears.
- 1.5 modulus gears — The 1.5 modulus specification ensures robust, durable gears that can withstand the extreme forces generated by a 1/5 scale monster truck, whilst maintaining smooth meshing and minimal noise during operation on any UK terrain.
- 100% drop-in compatibility — Designed specifically as a front centre differential upgrade for the Traxxas X-MAXX and XRT 1/5 models, this unit requires zero modifications to your existing chassis, electronics or suspension setup. Simply remove the old differential and install the new one.
- Complete all-in-one kit — Rather than hunting for individual components, this package includes everything needed for a complete centre differential replacement: the case, spider gears, bearings, pins, washers and all hardware. Nothing is left behind.
- Precision-machined components — All bearings, pins and washers are precision-machined to exacting tolerances, ensuring durability, reliability and a long service life even under the demanding conditions of competitive racing or aggressive bashing.
- Professional-grade silicone oil — The included PMX-200 silicone oil at 100K weight is a professional-standard lubricant that provides optimal damping characteristics for smooth differential operation, consistent turning performance, and reduced wear on internal components.
Technical Performance
The VITAVON Full Center Diff Case represents engineering excellence designed specifically for the demands of 1/5 scale RC racing and high-performance bashing. The 14/33T gear ratio is carefully engineered to provide the ideal balance between acceleration and top speed for centre differential operation in the X-MAXX and XRT platforms. The 1.5 modulus specification indicates a robust gear design that maximises the contact patch between meshing teeth, resulting in improved power transfer efficiency and reduced noise generation compared to smaller modulus gears. The pre-matched nature of these gears means they have been selected as a pair to ensure perfect mesh characteristics from day one — something that cannot be guaranteed when purchasing gears individually. The case itself is engineered from high-quality materials (specific material details confirm this is not budget aluminium but rather precision-machined engineering grade materials), and the inclusion of precision-machined bearings ensures minimal friction, smooth operation and extended component lifespan. The 100K weight PMX-200 silicone oil is a professional-grade lubricant commonly used in high-end RC differentials because it maintains consistent viscosity across temperature ranges, provides excellent lubrication film strength, and allows the differential to function smoothly whether you're driving in cool UK winter conditions or on a warm summer's day. This is a complete system designed by engineers who understand the specific demands of 1/5 scale monster trucks.

Frequently Asked Questions
- Will this centre differential fit my Traxxas X-MAXX or XRT? — Yes, this VITAVON differential is engineered as a 100% compatible upgrade specifically for the Traxxas X-MAXX and XRT 1/5 scale models. It is designed for the centre differential position and requires no modifications to your vehicle. Simply remove your existing centre differential and install this unit — it's a true drop-in replacement.
- Do I need any tools or special knowledge to install this differential? — Installation will require standard RC tools (hex keys, screwdrivers) and basic mechanical knowledge of RC vehicles. If you're comfortable removing and reinstalling the stock differential on your X-MAXX or XRT, you'll be able to install this VITAVON unit. The included hardware comprises everything needed — no additional parts required.
- Why is it pre-filled with silicone oil? — Pre-filling with 100K weight PMX-200 silicone oil saves you the hassle of purchasing oil separately and performing the setup yourself. This professional-grade oil is ideal for differential operation and is already at the manufacturer's recommended level, so you can install and use the differential immediately.
- What does the 14/33T gear ratio mean? — The 14-tooth and 33-tooth combination refers to the pinion and ring gears in the differential. This ratio is pre-matched during manufacturing to ensure smooth power transfer, consistent performance, and durability. The manufacturer has selected these specific gears as a matched pair rather than individual components.
- Is this suitable for both racing and bashing? — Yes, this differential is engineered for high-performance operation in both competitive racing and aggressive weekend bashing scenarios. The robust 1.5 modulus gears and precision-machined construction make it equally suitable for track use and off-road terrain. Whether you're chasing lap times or exploring rough UK countryside, this differential will perform reliably.
- How often will I need to service this differential? — Like all differentials, regular inspection and occasional oil changes are recommended depending on usage intensity. However, the robust engineering and professional-grade PMX-200 oil mean this unit will provide extended service intervals compared to budget alternatives. For casual use, annual inspection is typically sufficient; for competitive use, more frequent checks are recommended.
- What is the 1.5 modulus specification? — Modulus refers to the size and pitch of the gear teeth. A 1.5 modulus indicates robust, larger teeth compared to smaller modulus gears, resulting in superior load capacity, reduced noise, and longer component lifespan. This specification is ideal for the demands of 1/5 scale monster truck operation.
