Key Features
- Tough Composite Material — Manufactured from premium composite material specifically chosen for its durability and impact resistance, these gearbox covers and shock towers can withstand the rigours of intense RC driving without cracking or breaking under stress, ensuring your vehicle stays on the track or course for longer sessions.
- Precision Manufacturing — Each component is precision engineered to exacting tolerances, guaranteeing consistent fit with your ARRMA chassis and enabling straightforward servicing of your gearbox and suspension components without forcing parts or dealing with gaps that compromise performance.
- Integrated Multi-Function Design — Rather than being simple covers, these components integrate the gearbox cover, shock tower, body post mount, upper inner suspension mount and steering brace into one thoughtfully engineered assembly, reducing the number of separate parts you need to manage whilst maintaining structural integrity.
- High Specification Shock Towers — The shock tower design meets ARRMA's exacting standards for suspension geometry and durability, providing reliable mounting points for your shocks whilst maintaining proper suspension kinematics to keep your RC truck performing predictably across varied terrain.
- Lower Profile Design — These composite covers feature a lower profile compared to earlier AR320399 models, potentially offering improved aerodynamics, better ground clearance in certain driving conditions, and a more refined appearance on your RC vehicle.
- Easy Servicing Access — The design allows for straightforward access to gearbox components when maintenance or upgrades are required, saving you time and frustration when you need to work on your brushless RC truck's drivetrain or suspension components.
Technical Performance
These F/R Composite Upper Gearbox Covers and Shock Towers represent ARRMA's commitment to engineering excellence in chassis components. The composite material selection balances weight considerations with impact resistance—critical factors in high-performance RC driving where durability and precision matter equally. The integrated design philosophy means that the gearbox cover, shock tower, body post mount, upper inner suspension mount and steering brace function as a unified structural system rather than multiple separate components, enhancing chassis rigidity and response characteristics. For users of 1/10 scale brushless RC trucks and speed vehicles, maintaining proper gearbox housing integrity is essential for protecting drivetrain components whilst the shock towers maintain accurate suspension geometry during aggressive driving. The precision manufacturing ensures that these replacement parts meet the same specifications as original equipment supplied with ARRMA's ready to run RC vehicles, maintaining the performance baseline that buyers expect from the brand. The lower profile compared to previous iterations demonstrates ARRMA's ongoing refinement of chassis design, suggesting improved aerodynamics and potentially better ground clearance during high-speed runs.
