Overview
The ARRMA Rear Aluminum Shock Tower CNC 7075 T6 ML in striking red is a premium chassis upgrade component designed for serious RC enthusiasts who demand ultimate durability and precision engineering. This is not a complete vehicle, but rather a performance-focused replacement part for 1/8 scale ARRMA models including the KRATON 6S, NOTORIOUS 6S, and OUTCAST 6S EXB platforms. If you are running an RC monster truck or stunt truck and want to enhance your vehicle's rigidity and handling characteristics, this CNC-machined shock tower delivers the engineering quality that competitive bashers and weekend warriors expect from ARRMA's Extreme Bash (EXB) lineup.
Built from high-quality 7075-T6 aluminium, one of the most respected materials in RC car engineering, this shock tower combines incredible strength with lightweight performance. The CNC machining process ensures precision tolerances that mass-produced plastic parts simply cannot match, making this an ideal upgrade for anyone looking to improve chassis stiffness and shock mounting accuracy on their 1/8 scale RC truck. Whether you are maintaining your vehicle after hard use or upgrading for better handling, this component represents the kind of quality engineering that keeps ARRMA at the forefront of the RC hobby in the UK and worldwide.
The anodised ARRMA red finish is not merely cosmetic—anodisation provides a protective oxide layer that resists corrosion and wear, ensuring your investment remains protected through countless bashing sessions. The laser-etched EXB logo adds a professional touch while serving as permanent part identification. Multiple shock mounting positions built into this tower give you the advanced tuning flexibility that serious RC racers and bashers require to fine-tune suspension geometry for different terrains and driving styles.
Key Features
- CNC Machined 7075-T6 Aluminium Construction — This shock tower is precision-engineered using computer numerical control machining from aerospace-grade 7075-T6 aluminium, the gold standard in high-performance RC applications. This material delivers exceptional stiffness and durability compared to plastic alternatives, ensuring your chassis maintains its geometry under extreme stress and repeated impacts during high-speed runs and aggressive bashing.
- Superior Strength and Durability — The combination of premium aluminium alloy and precision CNC machining creates a component that is stiff, strong, and extremely durable. This means fewer breakages, longer component lifespan, and better overall reliability—critical factors for anyone serious about keeping their RC truck on the track or course rather than on the workbench.
- Anodised ARRMA Red Finish — The anodisation process creates a protective oxide layer that resists corrosion, scratches, and UV damage, keeping your shock tower looking fresh and maintaining its structural integrity through countless bashing sessions. The vibrant ARRMA red colour gives your vehicle an authentic Extreme Bash aesthetic that matches ARRMA's aggressive styling philosophy.
- Laser-Etched EXB Logo — The precision laser-etched Extreme Bash logo serves dual purposes: it adds professional visual appeal and provides permanent part identification for easy reference during maintenance and repairs. This attention to detail reflects ARRMA's commitment to quality in every component.
- Multiple Shock Mounting Positions — Advanced tuning flexibility is built into this tower through multiple shock mounting positions. These allow you to adjust suspension geometry to suit different driving conditions, terrain types, and driving styles, giving you the fine-tuning capability that separates casual bashers from competitive drivers.
Technical Performance
This rear shock tower represents a significant engineering upgrade over standard plastic chassis components found on many RC vehicles. The use of 7075-T6 aluminium alloy is deliberate and engineered—this material specification is identical to that used in high-stress aerospace applications and professional motorsport components. The CNC machining process ensures tolerances measured in fractions of a millimetre, meaning mounting points align perfectly with your suspension components and shocks seat with precision. The anodised surface treatment adds approximately 0.001 to 0.003 inches of protective coating, which may sound minimal but provides substantial corrosion resistance and wear protection in the demanding environment of RC bashing. The multiple shock mounting positions are strategically positioned to allow geometry changes ranging from softer, more compliant setups for rough terrain to stiffer, more responsive configurations for high-speed circuit driving. The weight penalty of aluminium versus plastic is minimal—typically adding just a few grams—but the rigidity gains translate directly to improved handling consistency, better shock performance, and reduced flex during cornering and jumps. This component is specifically engineered for 1/8 scale ARRMA vehicles including the KRATON 6S 4X4, NOTORIOUS 6S 4X4, and OUTCAST 6S EXB platforms, ensuring perfect fitment and compatibility with these demanding high-performance RC trucks.

Frequently Asked Questions
- Is this rear shock tower suitable for beginners or only advanced RC drivers? — While this is technically a replacement part rather than a complete vehicle, it is suitable for any RC enthusiast who wants to upgrade their chassis. Beginners benefit from the increased durability, as the aluminium construction is less likely to break during learning runs. However, you must already own a compatible ARRMA vehicle to use this component, as it is not a standalone product.
- What ARRMA models does this rear shock tower fit? — This shock tower is compatible with the following 1/8 scale ARRMA vehicles: KRATON 6S 4X4 Roller Brushless Speed Truck, KRATON 6S 4X4 RTR Brushless Speed Truck, NOTORIOUS 6S 4X4 RTR Brushless Stunt Truck, and OUTCAST 6S EXB AVC 4X4 RTR Brushless Stunt Truck. Before purchasing, verify your specific model against this compatibility list.
- Why should I upgrade from the standard plastic shock tower to this aluminium version? — The plastic shock towers found on stock ARRMA vehicles will flex and can crack under aggressive bashing, particularly when landing jumps or hitting obstacles. The 7075-T6 aluminium tower is dramatically stiffer, maintains its geometry through hard impacts, and lasts significantly longer. The improved rigidity directly translates to more consistent suspension performance, better handling predictability, and fewer repair sessions required—saving you time and money in the long run.
- Does this shock tower require any special tools for installation? — Installation requires standard RC model tools including hex drivers and potentially a torque wrench for precise fastener tightening. You will need to transfer your existing shocks and suspension components from the stock tower to this new unit. If you are uncomfortable with chassis modifications, consider having your local RC hobby shop perform the installation.
- Will upgrading to this aluminium shock tower improve my vehicle's handling? — Yes, the increased rigidity of the aluminium tower reduces unwanted flex in the chassis, which improves suspension response and handling consistency. This is particularly noticeable during aggressive cornering and when landing jumps from height. The multiple mounting positions also allow you to fine-tune suspension geometry for optimal performance in your local driving conditions.
- What makes 7075-T6 aluminium special for RC applications? — 7075-T6 is an aerospace-grade aluminium alloy known for exceptional strength-to-weight ratio. The T6 heat-treatment process creates a material that is significantly stronger than standard 6061 aluminium while remaining lightweight. This specific alloy is chosen for high-stress RC components because it resists deformation and maintains dimensional stability through repeated impacts and vibration.
