Replacing the front and rear axle gearbox with a CNC-machined metal assembly addresses these issues by providing a rigid mounting point for differentials and axle shafts. This upgrade is especially beneficial for WPL four-wheel drive chassis used on bumpy outdoor terrain where twisting forces are highest. The direct difference design ensures both axles receive power simultaneously, improving traction on loose surfaces. Whether you are performing maintenance after a rough run or building a custom project from the ground up, this metal gearbox set offers a practical foundation for a more durable driveline.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cp\u003eThis gearbox assembly is built around a simple but effective construction philosophy: replace flex-prone plastic with rigid iron. The key details focus on material, manufacturing method, and intended fitment for a specific platform.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe gearbox components are machined from iron, classified under metal model accessories. Iron provides a significantly higher stiffness-to-weight ratio compared to the standard polymer parts found on stock WPL trucks, reducing torsional flex during acceleration. The CNC fabrication process ensures that mounting holes and bearing seats are cut to tight tolerances, minimising play between the gearbox case and the axle shafts. This precision fit helps maintain gear mesh alignment even under heavy throttle application.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eNo length, width, or height dimensions are provided in the source text, so you should verify fitment against your specific WPL chassis version before purchase. The assembly is described as a direct replacement for the factory front and rear axle gearbox units, meaning it should share the same mounting pattern and axle tube spacing as the original plastic parts. Visually, the titanium colour is a distinctive silver-grey finish that stands out against black plastic chassis rails or suspension links.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cp\u003eThis upgrade component serves specific roles depending on your building or driving style. It is targeted at individuals who already own a compatible WPL four-wheel drive vehicle and want to strengthen the drivetrain without fabricating custom parts.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eFor club-level competition or organised trail drives, this metal gearbox reduces the chance of drivetrain failure mid-run. The rigid metal casing keeps the internal gears correctly spaced even when the chassis twists over ruts and rocks, reducing the risk of stripping teeth or ejecting diff gears. Hobbyists running heavier battery packs or larger wheels will benefit from the increased load capacity that iron construction offers over plastic.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eFor casual home use, such as driving the model around the garden or on tarmac paths, this metal gearbox is a set-and-forget upgrade. Once installed and lubricated, it requires minimal attention beyond occasional cleaning and re-lubrication. The titanium colour finish also adds a customised look that matches other CNC metal aftermarket parts, giving your WPL build a coherent visual theme under the body shell.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cp\u003eChoosing a metal drivetrain component represents a one-time investment in reliability. The practical advantages revolve around reduced maintenance frequency and improved vehicle behaviour.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eBecause iron does not deform under heat or load like plastic can, this gearbox assembly can be transferred between chassis or re-used across multiple builds if you change vehicle platforms. Cleaning requires only a brush and mild solvent to remove dirt and old grease before re-lubrication. This reusability contrasts with plastic parts that may develop hairline cracks after extended use and require complete replacement.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eIf you are experiencing drivetrain slop, gear slipping, or axle wobble on your WPL four-wheel drive model, this metal gearbox set directly addresses the root cause: insufficient casing rigidity. It is a targeted solution for a structural weakness in the stock design. While plastic gearboxes are adequate for low-power brushed systems, adding a metal case becomes more important if you upgrade to a brushless motor, which delivers higher torque that can twist a plastic gearbox housing out of shape. This metal assembly provides the necessary rigidity to unlock the full potential of performance upgrades without introducing drivetrain failure as a new weak point.\u003c\/p\u003e","brand":"110xwn-eb","offers":[{"title":"Titanium","offer_id":54124354339159,"sku":"CJQT122148301AZ","price":66.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1006\/9455\/7015\/files\/e050f65d-e8f9-4818-9066-77d65df0db8e.webp?v=1785041367","url":"https:\/\/shopprimex.com\/products\/metal-front-and-rear-axle-gearbox-for-wpl-rc-car-model-accessories-cnc-four-wheel-drive-direct-difference-assembly-titanium-colour-upgrade-part-from-iron-material-fabrication","provider":"ShopPrimex.com","version":"1.0","type":"link"}
