Overview

The RC Overhaul Metal Differential in red (G-RCO-AR024R) is a premium upgrade component designed for the GROM RC vehicle platform. This all-metal transmission upgrade takes your RC car UK setup to the next level, offering a dramatic improvement over standard plastic differentials. Whether you're running brushless power for maximum speed and responsiveness, or you prefer hard bashing and off-road adventures, this differential is engineered to handle the demands of both driving styles. Built and ready to use with high-temperature grease already applied, the RC Overhaul Metal Differential arrives factory assembled, so you can install it and get straight back to the action without delay.

This is the upgrade choice for serious RC enthusiasts who understand that the differential is one of the most critical components in any RC car's drivetrain. The differential distributes engine power to the wheels whilst allowing them to rotate at different speeds during cornering, and a quality differential makes all the difference to handling, acceleration, and overall drive feel. The RCO Metal Differential can be fitted both front and rear on your GROM, giving you total flexibility in tuning your vehicle's characteristics to suit your driving style and terrain. It's an ideal fit for anyone running a ready to run RC car who wants to upgrade to performance-level components without having to rebuild their entire vehicle.

RC Model Shop stocks this component because we recognise that serious RC car UK buyers want authentic upgrades from recognised manufacturers. RC Overhaul is trusted by the RC community for delivering quality transmission components that deliver real, measurable improvements in performance and durability. Whether you're a weekend basher looking to make your GROM tougher, or a more experienced RC enthusiast fine-tuning your setup, the RCO Metal Differential represents outstanding value at just £16.99.

Key Features

• All-metal construction — Unlike plastic differentials that can strip under load or break during hard impacts, this differential is constructed entirely from metal, providing superior strength and longevity even during intense brushless power delivery or aggressive bashing sessions.
• Full metal internal diff gears — The internal gear train is machined from quality metal rather than plastic, meaning the differential maintains its tolerances over thousands of cycles and delivers consistent, predictable handling characteristics run after run.
• Metal outdrives — The output shafts that connect the differential to your vehicle's driveshafts are metal components rather than plastic, dramatically reducing the risk of axle bending or breaking during high-torque acceleration or hard landings.
• Rubber-shielded bearings pre-installed — The differential arrives with quality bearings already fitted and sealed with rubber shields to keep dirt and water out while maintaining smooth rotation with minimal friction.
• Factory built and lubricated with high-temperature grease — You don't need to disassemble or rebuild this differential before installation; it ships pre-assembled and pre-lubricated with grease formulated to withstand the heat generated by both brushless motors and aggressive driving.
• O-rings on diff outputs for oil tuning — The sealed output shafts feature O-rings that allow you to run different viscosity differential oils, giving you precise control over how much slip the differential allows and therefore how your vehicle handles in corners.
• Front and rear compatibility — This single differential design works in both front and rear positions on the GROM, so one unit can upgrade either end of your vehicle, or purchase two for a complete drivetrain overhaul.
• Brushless and hard bashing ready — The robust metal construction is specifically engineered to handle the sustained torque of brushless motors and the shock loads generated by aggressive driving techniques.

Technical Performance

The RCO Metal Differential represents a significant engineering step forward compared to stock plastic differentials found on standard GROM vehicles. The all-metal construction means this component can handle peak torque levels that would cause plastic gears to strip or shatter. The metal outdrives resist bending under load, and the metal internal gear train maintains its precise tolerances even after hundreds of hard-acceleration cycles. The pre-installed rubber-shielded bearings are set up to deliver smooth rotation with minimal drag, helping your vehicle maintain momentum through corners and maintain consistent acceleration characteristics. Factory lubrication with high-temperature grease is specifically chosen to maintain viscosity and protective film strength under the extreme operating temperatures generated by brushless motor power or hard bashing. The O-ring sealed outputs allow you to experiment with 2000–7000 weight differential oils to fine-tune your vehicle's handling balance. For rear-end installation, RC Overhaul recommends starting with 2–3K viscosity oil, which provides enough slip to allow the inside rear wheel to rotate faster during cornering, improving turn-in and mid-corner stability. For front differentials, the higher 5–7K viscosity oil is suggested to provide more resistance to slip whilst still allowing directional changes without inducing understeer. This tuning flexibility means a single RCO Metal Differential can be adapted to suit different track conditions, driving techniques, and personal preferences. The complete metal construction ensures this differential will outlast multiple generations of plastic differentials, making it an excellent long-term investment for any serious RC enthusiast running a GROM.

Frequently Asked Questions

• Can I fit the RCO Metal Differential to my GROM without rebuilding the entire drivetrain? — Yes, absolutely. The RCO Metal Differential is a direct replacement for the stock differential and can be installed front or rear without requiring any modifications to other drivetrain components. The differential arrives factory assembled and pre-lubricated, so installation is straightforward and takes only a few minutes. Simply apply thread lock to the fasteners during installation to ensure everything stays secure during driving.
• Will this differential work with my brushless motor setup? — Yes, the RCO Metal Differential is specifically designed to handle brushless power. The all-metal construction and high-temperature grease are engineered to withstand the sustained high torque that brushless motors deliver. Many RC car UK users upgrade to metal differentials precisely because they're running brushless motors and need components that can keep up with that level of power.
• What differential oil do I need to use with this component? — The RCO Metal Differential features O-ring sealed outputs that allow you to use silicone differential oils of various viscosities. RC Overhaul recommends starting with 2–3K oil in the rear differential and 5–7K oil in the front. You'll need to purchase silicone diff oil separately; it's not included in the package. Different viscosity oils will change how much the differential slips during cornering, allowing you to fine-tune your vehicle's handling balance to suit your driving style and track conditions.
• Is the RCO Metal Differential suitable for hard bashing? — This differential is excellent for hard bashing. The all-metal construction is far more impact-resistant than plastic alternatives, and the metal outdrives are significantly less prone to bending when you hit kerbs, rocks, or other obstacles at speed. Many weekend bashers upgrade to metal differentials specifically to improve durability during aggressive driving.
• How do I maintain and service the RCO Metal Differential? — The RCO Metal Differential is maintenance-free for extended periods because it ships pre-lubricated with high-temperature grease. If you do need to service it, simply apply thread lock to fasteners when reassembling. You can experiment with different viscosity differential oils to adjust the slip characteristics without fully disassembling the unit. The rubber-shielded bearings are sealed to resist dirt ingress, helping to extend service intervals.
• Can I fit one RCO Metal Differential, or do I need to buy two? — This differential can be fitted to either the front or rear position on your GROM, so a single unit will upgrade one end of your vehicle. Many enthusiasts purchase two units (one for front and one for rear) to achieve a complete drivetrain upgrade with matched components, though fitting just one is perfectly viable if you want to start with a single upgrade.
• What is the difference between the RCO Metal Differential and other metal differentials available? — The RCO Metal Differential is purpose-designed for the GROM platform by RC Overhaul, meaning the fitment, tolerances, and performance characteristics are optimised specifically for your vehicle. It features full metal internal gears, metal outdrives, and pre-installed rubber-shielded bearings, setting it apart from lower-cost alternatives that may use mixed construction or lower-quality bearing seals. The factory lubrication with high-temperature grease and the O-ring sealed outputs for oil tuning are professional features that justify the relatively modest investment.
