The pair format means you're getting both sides of your crawler equipped with premium components, ensuring balanced handling and durability across your entire vehicle.
Key Features
- Precision Alloy Construction — Manufactured from high-quality aluminium rather than plastic, these caster mounts deliver superior strength and durability while maintaining lightweight properties. Aluminium components resist flexing and wear better than standard plastic parts, ensuring your crawler maintains precise handling characteristics even after extensive use on challenging terrain.
- Portal Axle Compatible — These caster mounts are specifically engineered to work with the FTX Outback Fury/Hi-Rock Alloy Portal Axle Conversion system, making them essential if you're upgrading to portal axles or replacing existing components. Portal axles provide authentic scale appearance and improved ground clearance on your crawler.
- Pair Included — You receive both left and right caster mounts in a single package, ensuring your entire front or rear axle assembly is upgraded with matching quality components that work together in perfect harmony.
- OEM Quality Parts — As genuine FTX spares manufactured by the same engineers who design the vehicles, these components maintain perfect fitment, durability standards, and aesthetic consistency with your original crawler.
- Enhanced Scale Realism — Portal axles and their associated mounting components add authentic visual detail and functional realism to your scale crawler, elevating it from a basic toy to a serious scale replica of real-world extreme terrain vehicles.
- Direct Replacement Compatible — These caster mounts are designed as direct upgrades for FTX Outback Fury and FTX Hi-Rock 4x4 models, integrating seamlessly with existing suspension systems, driveshafts, and chassis components without modification.
- Professional-Grade Durability — Aluminium construction provides excellent resistance to impact, flexing, and fatigue cracking under the demanding conditions of trail running and rock crawling, ensuring long-term reliability and performance.
Technical Performance
The FTX Outback Fury/Hi-Rock Alloy Portal Axle Caster Mount represents the pinnacle of upgrade component engineering for 1/10 scale trail rock crawlers. These precision-machined aluminium parts form a critical component of the portal axle conversion system, where the caster mount angles and positions the axle assembly to achieve authentic scale geometry and improved ground clearance. The alloy construction is approximately three to four times stronger than equivalent plastic components whilst adding negligible weight, meaning your crawler benefits from improved rigidity without any penalty to performance. The machining tolerances are factory-set to ensure perfect fitment with FTX portal axle gears, shafts, and housing components, maintaining the precise alignment necessary for smooth, silent operation and minimal wear. Aluminium's excellent thermal properties also help dissipate heat during extended driving sessions, protecting internal components and maintaining consistent performance in competitive trail conditions. These mounts support the complete portal axle conversion system and work in conjunction with other FTX portal components including the alloy portal gear sets, rear shaft mounts, steering linkages, and panhard bars, allowing you to build a completely upgraded, competition-ready crawler platform.

Frequently Asked Questions
- What is a portal axle and why would I want to upgrade to one on my FTX Outback Fury or Hi-Rock? — Portal axles are a real-world feature of extreme terrain vehicles like rock crawlers and military vehicles, where the axle is mounted directly beneath the wheel hub rather than above it. This design increases ground clearance and raises the vehicle's centre of gravity in a unique way that improves obstacle climbing ability. The alloy caster mounts are essential components of this system, properly positioning the axle relative to the suspension links and steering components. For UK RC enthusiasts, upgrading to portal axles adds authentic scale realism, improves performance on technical terrain, and transforms your crawler's appearance to match genuine crawling vehicles seen in real-world competitions.
- Will these alloy caster mounts fit my existing FTX Outback Fury or Hi-Rock without other upgrades? — The caster mounts are specifically designed to work with the FTX Outback Fury/Hi-Rock Alloy Portal Axle Conversion system. While the mounts themselves will physically fit, you'll achieve optimal performance, alignment, and functionality only when using them with the complete portal conversion kit, which includes matching portal gears, rear shaft mounts, steering linkages, and other coordinated components. We recommend installing the complete conversion system rather than individual components to ensure perfect compatibility and performance.
- How do alloy caster mounts perform compared to plastic alternatives? — Aluminium caster mounts offer several performance advantages over standard plastic components. They resist flexing under load, maintain precise angles and alignment during aggressive driving, resist impact damage better, maintain tighter tolerances over time, and help dissipate heat from the axle assembly. For serious trail runners and competitors, the improved durability and performance characteristics make alloy upgrades a worthwhile investment that extends vehicle lifespan and maintains competitive performance through many seasons of use.
- Can I upgrade my crawler gradually or do I need the entire portal conversion system at once? — The FTX Outback Fury/Hi-Rock Alloy Portal Axle Conversion system is designed modularly, allowing you to upgrade gradually. You can purchase the complete conversion set for comprehensive transformation, or you can purchase individual components like these caster mounts as replacements or incremental upgrades. However, for first-time portal conversions, we recommend purchasing the complete FTX Outback Fury/Hi-Rock Alloy Portal Axle Conversion Set to ensure all components are engineered to work together perfectly and to avoid compatibility issues.
- How difficult is it to install these alloy caster mounts? — Installation difficulty depends on whether you're upgrading from a standard Outback Fury/Hi-Rock or performing an initial portal conversion. If you're completing a full portal conversion, the mounts are installed as part of the systematic assembly of the conversion kit. If you're replacing existing portal caster mounts, installation is straightforward for anyone with basic RC mechanical skills and standard hex key tools. We recommend consulting the full FTX portal conversion instructions or visiting RC forums where UK enthusiasts share detailed installation guides and tips.
- What other components should I upgrade alongside these caster mounts? — These caster mounts work best as part of the complete portal axle system. Consider upgrading these components simultaneously: FTX Outback Fury/Hi-Rock Alloy Portal Axle Housing (FTX9216), FTX Outback Fury/Hi-Rock Alloy Portal Gear Set (FTX9218-5), FTX Outback Fury/Hi-Rock Alloy Portal Rear Shaft Mount & Cover (FTX9218-4), FTX Outback Fury/Hi-Rock Alloy Portal Steering Bushings (FTX9218-9), FTX Outback Fury/Hi-Rock Alloy Portal Steering Link (FTX9218-11), and FTX Outback Fury/Hi-Rock Alloy Portal Panhard Bar (FTX9218-10).
