Key Features
- 0.8 Module Main Gear — The 0.8 MOD main gear specification provides ultimate durability and strength, allowing the differential to handle the demands of high-performance RC driving whilst maintaining reliable power transfer from the motor to the wheels. This modular specification is a standard in professional RC builds.
- Precision Manufactured Design — Each gear and component is precision engineered to ensure accurate tooth mesh, which reduces wear, minimises noise, and maximises efficiency in power transmission. This manufacturing precision directly translates to smoother acceleration and more predictable handling characteristics on the track or trail.
- Tough Precision Aluminium Diff Case — The differential case is constructed from precision-machined aluminium, which ensures perfect alignment between all internal gears and provides the rigidity necessary to handle the stresses of off-road and on-road RC driving. Aluminium construction also helps keep weight to a minimum whilst maximising strength.
- High Strength Steel Internal Gears and Splined Output Shafts — The straight-cut internal gears and splined diff output shafts are manufactured from high-strength steel, giving them the ability to withstand the torque and lateral forces generated during aggressive acceleration, sharp cornering, and high-speed runs. Steel construction ensures longevity even under extreme driving conditions.
- Pre-Assembled and Ready to Install — This centre differential arrives fully assembled and filled with silicone oil, ready to drop into your ARRMA vehicle. There's no need to source individual parts, measure gear mesh, or fiddle with assembly – simply remove the old differential, install the new one, and you're ready to drive.
- Filled with 500,000cSt Silicone Oil — The differential is pre-filled with 500,000cSt viscosity silicone oil, which provides superior lubrication and thermal stability during driving. This high-viscosity oil ensures that all internal components operate smoothly and remain protected against wear, extending the life of your differential and maintaining consistent performance across different driving conditions and temperatures.
Technical Performance
The ARRMA 57T Metal Center Diff Set represents the pinnacle of differential engineering for modern brushless RC vehicles. The 0.8 MOD specification combined with the 57-tooth configuration provides an optimal balance between torque delivery and durability. The precision-manufactured gear teeth ensure minimal backlash and maximum efficiency, meaning more of your motor's power reaches the wheels rather than being lost to friction and wear. The tough precision aluminium diff case provides the structural rigidity needed to maintain accurate gear alignment even when subjected to the extreme forces encountered during high-speed cornering, jumps, and aggressive acceleration in competitive RC racing or casual bashing. The high-strength steel straight-cut internal gears and splined output shafts are engineered to handle repeated stress cycles without stripping, cracking, or deforming. The pre-filled 500,000cSt silicone oil ensures that even under heavy use, the differential remains properly lubricated and operates at optimal efficiency. This combination of materials, design, and engineering makes it an ideal upgrade or replacement for owners of ARRMA 1/10 and 1/8 scale vehicles including the BIG ROCK, GRANITE, KRATON, OUTCAST, SENTON, VORTEKS, INFRACTION, MOJAVE and TYPHON models across multiple generations.

- 1 x Pre-Assembled Metal Center Diff Set (57T, 0.8M) – fully assembled and filled with 500,000cSt silicone oil, ready for immediate installation
Frequently Asked Questions
- Is the ARRMA 57T Metal Center Diff Set compatible with my ARRMA RC model? — Yes, this centre differential is compatible with a wide range of ARRMA vehicles including the 1/10 BIG ROCK 223S, GRANITE 223S, KRATON 4S, OUTCAST 4S, SENTON 223S, VORTEKS 223S, INFRACTION 223S, and the 1/8 scale MOJAVE 4S and TYPHON 223S models. Check the comprehensive compatibility list in the product details to confirm your specific model.
- Do I need any special tools to install this differential? — The centre differential is supplied pre-assembled and ready to drop into your ARRMA vehicle, so you shouldn't need specialist tools for installation. However, you may need basic RC hobby tools such as a hex driver set and screwdrivers to remove the old differential and secure the new one in place. Always consult your vehicle's user manual for specific installation instructions.
- What makes this metal differential better than a plastic one? — Metal differentials offer superior durability, strength and longevity compared to plastic alternatives. The high-strength steel gears and splined shafts resist wear far better than plastic components, and the precision aluminium case maintains perfect gear alignment under stress. This means fewer replacements, more consistent performance, and better value over time for serious RC enthusiasts.
- Why does the differential come filled with 500,000cSt silicone oil? — The 500,000cSt viscosity silicone oil provides optimal lubrication and thermal stability for the differential gears and bearings. This high-viscosity oil remains effective across a wide temperature range, reduces friction and wear, and helps dissipate heat generated during high-performance driving. The pre-filled design means you get consistent performance straight out of the box.
- Can I use this differential as an upgrade if my vehicle didn't come with a metal centre diff? — Yes, if your ARRMA vehicle is listed as compatible and currently uses a standard differential, you can upgrade to this metal version. The upgrade will improve durability and performance, particularly if you engage in high-speed racing or aggressive off-road driving. Always verify compatibility with your specific model before purchasing.
- Is this suitable for beginners? — Whilst this is a genuine ARRMA replacement part suitable for all skill levels, it is primarily a drivetrain component and not a complete vehicle. If you're new to RC, you'll need a complete ready-to-run RC model to use this differential. Once you have an ARRMA vehicle, this differential upgrade is straightforward to install and will improve your vehicle's performance and durability.
