Key Features
- Tough Composite Material — Constructed from durable composite material that resists impact damage and prolonged use, these covers maintain their shape and appearance through countless bashings, ensuring long-lasting durability even in demanding track or off-road conditions.
- Precision Manufactured — Each component is manufactured to exacting tolerances, guaranteeing consistent fit across units and making installation and servicing straightforward without the need for trimming or adjustment.
- Integrated Multi-Function Design — Rather than separate components, the shock tower and gearbox cover integrate the gearbox cover, shock tower, body post mount, upper inner suspension mount and steering brace into one efficient unit, simplifying the chassis design and reducing assembly time.
- Low Profile Shock Towers — The shock tower profile has been optimised for low mounting, allowing you to fit your bodyshell lower on the chassis for improved aerodynamics, better weight distribution and a more aggressive stance on your RC car.
- High Specification Shock Towers — Engineered to handle the forces generated by aggressive driving, jumping and rough terrain, these shock towers provide the structural support needed for reliable, consistent performance across a wide range of driving conditions.
- Easy Servicing Access — The precision-engineered design provides clear access to the upper suspension mounting points, making routine maintenance, gear adjustments and component replacement faster and more straightforward.
Technical Performance
The ARRMA Composite Upper Gearbox Covers and Shock Tower deliver professional-grade engineering through their integrated multi-function design philosophy. Built from tough composite material, these components provide exceptional structural rigidity whilst remaining lightweight, a critical balance for high-performance RC trucks. The precision manufacturing process ensures that every unit fits consistently, eliminating tolerance issues that can lead to binding, misalignment or loose components during operation. The integrated design combines five functional elements—the upper gearbox cover, shock tower, body post mount, upper inner suspension mount and steering brace—into a unified structure. This approach not only simplifies assembly but also improves overall chassis strength by reducing the number of mounting points and fasteners. The low-profile shock tower design is particularly valuable for enthusiasts who want to lower their bodyshell position, improving the centre of gravity and aerodynamic characteristics whilst maintaining full suspension articulation. The high-specification shock towers are engineered to transfer suspension loads effectively, supporting both the vertical movement of the shocks and the lateral forces encountered during cornering, jumping and aggressive off-road driving. These components are manufactured to work seamlessly with ARRMA's suspension geometry, ensuring that your vehicle's handling characteristics remain optimised and your driving experience remains predictable and enjoyable.

Frequently Asked Questions
- Which ARRMA models are compatible with the Z-ARA320584 gearbox covers? — The ARRMA Composite Upper Gearbox Covers and Shock Tower are compatible with the ARRMA INFRACTION 4X4 1/8 3S BLX Resto-Mod Truck RTR. If you own a different ARRMA model such as the KRATON or OUTCAST, please verify compatibility with our team before ordering, as different models within the ARRMA range may use alternative parts specifications.
- Are these replacement parts suitable for beginners? — Yes, these components are ideal replacement parts suitable for all experience levels. If your original gearbox covers or shock towers become damaged through normal use, these genuine ARRMA parts are straightforward to fit and maintain your vehicle at factory specification. Installation requires basic tools and moderate mechanical knowledge, making them accessible to most RC enthusiasts.
- What material are the gearbox covers made from? — These covers are manufactured from tough composite material, which provides an excellent balance of durability, weight and cost-effectiveness. Composite material resists impact damage better than plastic whilst remaining lighter than aluminium, making it ideal for off-road and bashing applications where durability is essential.
- Do these covers require any modification to fit? — No, these precision-manufactured parts are designed to fit consistently without modification. The precision manufacturing process ensures that every unit has the same tolerances, so installation should be straightforward without trimming, filing or adjustment.
- What is the benefit of the integrated shock tower design? — The integrated design combines the shock tower, gearbox cover, body post mount, upper inner suspension mount and steering brace into a single component. This approach simplifies the chassis architecture, reduces the number of separate parts you need to source and manage, and improves overall structural rigidity by consolidating mounting points.
- Will the low-profile shock tower allow me to fit a lower bodyshell? — Yes, the low-profile design of the shock tower has been engineered to allow lower bodyshell mounting whilst maintaining full suspension articulation and clearance. This lets you improve your vehicle's appearance and lower the centre of gravity for better handling characteristics.
