If you own an ARRMA 1/5 scale monster truck or are building a custom brushless RC setup, this shock tower is a direct replacement part that meets OEM specifications. The laser-etched design adds visual appeal while the CNC precision ensures perfect fitment. ARRMA is recognised worldwide for producing some of the toughest ready to run RC vehicles available, and this component exemplifies that commitment to quality and durability that has made ARRMA a trusted name in the RC hobby across the UK and beyond.
Key Features
- 7075 T6 Aerospace-Grade Aluminium Construction — This shock tower is machined from 7075 T6 aluminium, the same material used in aircraft construction, which offers exceptional strength-to-weight ratio and superior rigidity compared to standard aluminium alloys. This ensures the tower resists bending and maintains perfect geometry even under extreme bashing loads and high-speed impacts.
- CNC Precision Machining — Every shock tower is precision CNC machined to exact tolerances, guaranteeing perfect fitment and alignment with your suspension components. This manufacturing process eliminates dimensional variance and ensures consistent performance across multiple units, which is critical for reliable off-road performance.
- Laser-Etched ARRMA Branding — The laser-etched ARRMA logo and design not only adds professional aesthetics but also serves as a quality mark indicating this is a genuine, authentic ARRMA component from an authorised dealer. The engraving is permanent and won't wear off with use.
- Red Anodised Finish — The vibrant red anodised coating provides multiple benefits including superior corrosion resistance, protection against oxidation, enhanced durability in wet conditions, and a distinctive aggressive appearance that matches ARRMA's EXB colour scheme perfectly.
- Compatible with 20mm Bore Oil-Filled Shocks — This shock tower is engineered to mount ARRMA's advanced 20mm bore oil-filled shock absorbers with 6mm thick shock shafts, enabling optimal suspension performance and bump absorption on all terrain including dirt, asphalt and grass.
- Ultra-Thick Composite Construction — The shock tower integrates with ARRMA's ultra-thick composite design philosophy, providing reinforced mounting points that distribute impact loads effectively and prevent premature failure during extreme bashing sessions.
- OEM Replacement Component — This is an official ARRMA replacement part engineered to match original equipment specifications, ensuring seamless compatibility with your 1/5 scale monster truck chassis and suspension system without modification.
- EXtreme Bash Rated — This component is part of ARRMA's EXB (EXtreme Bash) range, meaning it has been specifically engineered and tested for extreme durability, making it suitable for high-speed bashing and competitive off-road use.
Technical Performance
The ARRMA Front Shock Tower CNC 7075 T6 Aluminium Red represents the engineering excellence that ARRMA brings to high-performance RC vehicles. Machined from 7075-T6 aluminium, this shock tower combines the lightweight properties essential for off-road performance with the structural rigidity required to survive extreme impacts. The 7075 T6 alloy offers approximately 73,500 PSI yield strength, making it significantly more resistant to deformation than standard 6061 aluminium commonly used in lesser-quality RC components. The CNC machining process ensures dimensional accuracy to within fractions of a millimetre, critical for mounting ARRMA's advanced 20mm bore oil-filled shocks that feature 6mm thick hardened steel shock shafts. These shocks deliver plush damping characteristics and excellent bump absorption, with the shock tower's substantial construction providing the stable, rigid mounting platform required for consistent performance. The red anodised finish adds approximately 0.0005 to 0.0025 inches of protective coating, effectively sealing the aluminium surface against moisture, salt spray, and chemical corrosion — essential for maintaining structural integrity when running in wet conditions or on saltwater beaches. When integrated into the broader ARRMA 1/5 scale monster truck chassis (featuring 5mm thick laser-etched 7075-T6 aluminium chassis plates and reinforced composite side pods), this shock tower contributes to a suspension system capable of handling sustained high-speed operation and severe terrain without compromise. The engineering philosophy behind this component reflects ARRMA's commitment to creating ready to run RC vehicles that combine raw power with exceptional durability, making them the choice of serious bashers across the UK and internationally.

Frequently Asked Questions
- Is this ARRMA Front Shock Tower compatible with all ARRMA 1/5 scale monster trucks? — This CNC 7075 T6 aluminium shock tower is specifically engineered for ARRMA's 1/5 scale monster truck platform, including the KRATON 8S EXB and related models. Always verify compatibility with your specific vehicle model before purchasing, as ARRMA produces multiple chassis variations. Check your vehicle's manual or contact customer support if you're uncertain about fitment.
- What makes 7075 T6 aluminium better than standard aluminium for RC components? — 7075 T6 aluminium is an aerospace-grade alloy that offers significantly higher strength and rigidity compared to standard 6061 aluminium. The T6 heat treatment process creates a tempered state that maximises hardness and yield strength, making it ideal for components that must resist bending and deformation under extreme loads. For high-performance brushless RC vehicles running 8S LiPo batteries, this material is essential for reliability.
- Can I use this shock tower with standard non-oil-filled shocks? — This shock tower is specifically designed for ARRMA's 20mm bore oil-filled shocks. Whilst the mounting holes may accommodate other shock types, ARRMA engineers their suspension systems as integrated units where shock tower design complements specific shock geometry and damping characteristics. For optimal performance and safety, use only ARRMA-approved oil-filled shocks with this tower.
- How does the laser-etched design affect the component's performance? — The laser-etching process creates surface detail without removing significant material or creating stress points, so the design is purely aesthetic and does not impact structural performance. The laser-etching confirms this is an authentic ARRMA component from an authorised retailer, as genuine parts feature this distinctive branding.
- Is this a direct replacement for the standard shock tower on my ARRMA monster truck? — Yes, this CNC 7075 T6 aluminium shock tower is an official ARRMA replacement component engineered to OEM specifications. It will install directly into your compatible ARRMA chassis without modification, and the red anodised finish coordinates with ARRMA's EXB colour scheme for a professional appearance.
- What is the difference between this CNC-machined tower and stamped or cast alternatives? — CNC machining produces superior dimensional accuracy, eliminates internal casting flaws or inconsistencies, and allows for precise material thickness variation to optimise strength-to-weight ratio. Stamped or cast shock towers cannot match this precision, resulting in less consistent performance and potentially weaker mounting interfaces. The CNC process also enables the laser-etching detail that identifies this as an authentic ARRMA component.
- Will this shock tower help my RC monster truck handle better at high speeds? — A rigid, precisely-manufactured shock tower contributes to overall chassis stiffness and suspension geometry consistency, which helps maintain predictable handling at high speeds. Combined with ARRMA's advanced oil-filled shocks and control systems like Spektrum AVC (Active Vehicle Control), a quality shock tower supports responsive, controllable handling in demanding conditions.
- Is this component waterproof? — The aluminium shock tower itself is not a sealed component and does not contain electronics, so it poses no waterproofing concerns. The anodised coating provides corrosion resistance suitable for wet conditions, and the tower integrates with ARRMA's waterproof electronics module design to protect sensitive components. ARRMA rates their complete vehicles as water-resistant, suitable for wet terrain operation.
