Overview
The ProLine 1/10 Carbon Fiber Rear Shock Tower Brace is a premium upgrade component designed specifically for ARRMA 3S and MEGA vehicles. If you're serious about improving the stability and performance of your RC car, this precision-engineered brace represents a significant step forward in chassis rigidity and durability. Whether you're a seasoned RC enthusiast looking to maximise your 3S powered machine's potential, or someone exploring high-performance tuning options for your ARRMA, this shock tower brace delivers tangible improvements to handling and longevity.
Pro-Line has engineered this carbon fibre component to address a common weakness in stock RC chassis design: insufficient bracing around the shock towers. During aggressive driving, lateral forces and impacts can cause flex in the shock tower mounting points, which compromises suspension geometry and leads to unpredictable handling characteristics. This ProLine brace eliminates that flex entirely, restoring precision alignment and responsiveness to your RC buggy, truck or truggy. For UK RC enthusiasts running their vehicles hard in competitive settings or challenging terrain, this upgrade is a smart investment in chassis strength and performance consistency.
Installation is straightforward and requires no modification to your existing chassis. The brace is contoured to integrate seamlessly with your vehicle's bumper mount, creating a clean, factory-appearance installation that looks as good as it performs. All necessary hardware is included in the box, so you can have your RC car upgraded and ready to hit the track or trail within minutes.
Key Features
- Carbon Fibre Construction — The use of advanced carbon fibre composite material delivers exceptional strength-to-weight ratio, meaning you gain structural rigidity without adding unnecessary mass to your RC vehicle. This is crucial for maintaining handling balance and acceleration characteristics whilst significantly increasing chassis durability.
- Enhanced Shock Tower Strength — This brace directly reinforces the shock tower mounting points, which are critical stress zones during cornering, jumps and hard landings. By triangulating these mounting points, the brace distributes loads more evenly across the chassis and prevents the micro-movements that degrade suspension performance and cause premature component wear.
- Contoured Bumper Mount Integration — Rather than bolting on as an afterthought, this brace is precisely contoured to tie into your vehicle's bumper mount system. This engineering detail means the brace becomes part of the structural load path rather than a peripheral upgrade, maximising its reinforcement effectiveness and maintaining the clean aesthetics of your RC car's front end.
- Complete Installation Hardware Included — ProLine has included all necessary M3 anodised aluminium CTSK washers and M3x24 flat-head cap screw fasteners, eliminating the need to source additional hardware and ensuring you have everything required for immediate installation.
- Universal ARRMA 3S and MEGA Compatibility — This single brace design accommodates the entire range of ARRMA's 3S and MEGA platform vehicles, providing excellent value and flexibility whether you own a Granite, Senton, Big Rock, Vorteks or Typhon.
Technical Performance
The ProLine carbon fibre rear shock tower brace represents a significant engineering upgrade over stock components. Carbon fibre offers superior stiffness compared to the plastic and aluminium used in factory shock towers, whilst remaining lightweight enough that it won't negatively impact acceleration or handling balance. The material's high strength-to-weight ratio is particularly important for 3S-powered ARRMA vehicles, which generate substantial forces during acceleration, cornering and landing impacts. The brace's contoured design means it works in harmony with your vehicle's existing bumper mount system, creating a fully integrated structural reinforcement rather than competing with other chassis components. The included M3 anodised aluminium hardware is corrosion-resistant and precisely sized to avoid over-tightening damage whilst maintaining secure fastening. This upgrade is especially valuable for UK RC enthusiasts who regularly bash their vehicles in damp conditions or competitive environments where chassis durability directly impacts performance consistency and longevity.

Frequently Asked Questions
- Will this shock tower brace fit my ARRMA vehicle? — Yes, this ProLine brace is specifically designed for ARRMA 3S and MEGA platform vehicles. It is confirmed compatible with Granite 3S, Granite MEGA, Senton 3S, Senton MEGA, Big Rock 3S, Big Rock MEGA, Vorteks 3S, Vorteks MEGA, Typhon 3S and Typhon MEGA. Simply confirm your vehicle matches one of these models before ordering.
- Do I need any tools or additional hardware to install this brace? — Installation requires only basic tools such as a small hex key (Allen key) to tighten the M3 fasteners. All necessary hardware including washers and screws are included in the box, so no additional purchases are needed. The installation process is straightforward and should take less than 10 minutes for users with basic mechanical experience.
- What performance improvements will I notice? — The primary benefit is improved chassis rigidity, which translates to more predictable handling, better suspension geometry consistency, and reduced flex during aggressive cornering and jumping. You may also notice improved landing stability after jumps and more responsive steering feedback. For competitive RC car users, these improvements can directly impact lap times and consistency. Durability also improves as the reinforced shock towers resist damage from hard impacts.
- Is this suitable for beginners? — Whilst this is an intermediate-level tuning upgrade rather than a beginner component, installation is simple enough for new RC enthusiasts to handle. However, you should already own an ARRMA 3S or MEGA vehicle and have basic familiarity with removing and reinstalling chassis components. If you're new to RC tuning, this represents a great first upgrade project to build confidence with component installation.
- How does this compare to the stock shock towers? — Stock ARRMA shock towers are plastic or basic aluminium and flex slightly under load, which causes suspension geometry changes during aggressive driving. This ProLine carbon fibre brace eliminates that flex entirely whilst adding almost no weight. The result is a chassis that maintains precise suspension alignment and delivers consistent handling characteristics lap after lap, making it essential for serious RC enthusiasts prioritising performance.
- Can I use this with other chassis upgrades? — Absolutely. This shock tower brace works in harmony with most other ARRMA chassis upgrades and tuning components. Many experienced RC builders combine this with other rigidity upgrades such as chassis braces, layshaft braces and suspension arms to create a fully reinforced platform. There are no compatibility issues with standard or aftermarket ARRMA components.
