Key Features

• CNC Machined Precision — Every diff cover is precision-machined from solid billet aluminium using computer numerical control technology, ensuring perfect dimensional accuracy and consistency between units. This manufacturing process delivers a product that maintains tight tolerances and professional-grade fit every single time.
• Billet Aluminium Construction — The use of premium billet aluminium provides exceptional strength-to-weight ratio compared to plastic alternatives, giving you a component that won't crack, warp or degrade over time even with regular use on your RC crawler.
• Smooth Red Anodised Finish — The protective red anodised coating serves dual purposes: it creates an authentic appearance that matches full-size ARB diff covers whilst simultaneously protecting the underlying aluminium from oxidation and corrosion caused by moisture and dirt exposure.
• Authentic ARB Collaboration — This is not a generic diff cover design—it's a faithful scale replica created in partnership with ARB 4x4 Accessories themselves, meaning you're getting genuine accuracy in every line, curve and detail that reflects the real-world product.
• Includes Hardware and Decals — The package includes steel socket head cap screws (M1.6 x 4mm specification) for secure installation and an official ARB decal sheet, allowing you to add authentic branding to your scale model and complete the authentic look.
• Lightweight Scale Design — Weighing just 0.48 ounces (13.5 grams), this diff cover adds minimal rotational mass to your TRX-4 while delivering maximum visual impact, ensuring your crawler's handling characteristics remain unaffected.
• Perfect TRX-4 Fitment — Specifically engineered for Traxxas TRX-4 axles, this upgrade fits seamlessly without modification, requiring no drilling, cutting or permanent alterations to your model.

Technical Performance

The RC4WD ARB Diff Cover represents an exceptional example of precision engineering applied to RC scale accessories. Crafted from billet aluminium and finished with professional-grade red anodising, this component delivers the durability and aesthetic authenticity that serious scale crawler enthusiasts demand. The CNC machining process ensures that every unit meets exacting dimensional standards, with width of 1.38 inches (35mm), length of 1.50 inches (38mm), and height of 0.73 inches (18.5mm), creating perfect proportions for the Traxxas TRX-4 platform. The lightweight construction at just 13.5 grams ensures that adding this upgrade won't compromise your TRX-4's performance characteristics or handling dynamics. The smooth red anodised finish isn't merely decorative—anodisation is an electrochemical process that hardens the aluminium's surface layer, creating a protective barrier against corrosion, weathering, and the rigours of outdoor RC use. This treatment ensures that your investment will maintain its appearance and structural integrity through countless bashings, crawling sessions, and outdoor adventures. The partnership with ARB 4x4 Accessories guarantees that the design reflects genuine engineering principles borrowed from full-size automotive applications, bringing real-world quality and authenticity to your 1/10 scale model. Whether you're driving your TRX-4 on rocky terrain or displaying it in a collection, this diff cover will enhance both durability and visual appeal.

• What makes this better than plastic diff covers? — The billet aluminium construction provides superior strength, longevity, and corrosion resistance compared to plastic alternatives.
