Overview
The LOS Front Upper Arm Set (2) for the Super Rock Rey is an essential replacement or upgrade component designed for serious RC enthusiasts who demand reliability and performance from their ready to run RC models. These front upper arms are purpose-built suspension components that work in harmony with the Super Rock Rey's long-travel independent front suspension system, ensuring precise steering geometry and responsive handling characteristics across all terrain types. Whether you're a seasoned bashers, weekend competitor, or dedicated collector of brushless RC trucks, having quality replacement suspension parts on hand is crucial for maintaining peak performance and extending the lifespan of your investment in quality RC hobby equipment.
Super Rock Rey chassis platforms are renowned in the RC community for their robust engineering, scalable power options, and exceptional value. The front upper arms play a critical role in the suspension geometry, directly influencing how your RC vehicle responds to steering inputs, maintains traction during acceleration, and handles cornering forces. This two-pack replacement set ensures you have a spare pair available, minimising downtime and keeping your rock crawling, desert running, or general bashing sessions going without interruption. RC Model Shop stocks genuine Losi parts, giving you confidence that you're installing components engineered to exact OEM specifications and material standards.
For UK RC enthusiasts seeking authentic Losi replacement parts, the LOS Front Upper Arm Set represents genuine value and peace of mind. Losi has established itself as a leading manufacturer of affordable yet capable off-road RC vehicles, and their commitment to parts availability means you can service and upgrade your Super Rock Rey for years to come. If your front upper arms have suffered damage from impacts, rocks, or general wear during aggressive driving sessions, this OEM-quality replacement set will restore your suspension geometry and handling characteristics to factory specifications.
Key Features
- Genuine Losi OEM Parts — These front upper arms are manufactured to Losi's exact specifications, ensuring perfect fitment and compatibility with your Super Rock Rey chassis without any modification or adjustment required.
- Two-Piece Set — The pack includes both left and right front upper arms, giving you complete coverage for both sides of the front suspension and eliminating the need to purchase multiple individual components.
- Long-Travel Suspension Compatibility — Engineered specifically for the Super Rock Rey's long-travel independent front suspension geometry, these arms maintain proper suspension angles and articulation across full compression and extension cycles.
- Durable Construction — Built from quality materials selected to withstand the stresses of off-road RC driving, including rock impacts, high-speed landings, and aggressive cornering forces typical of desert truck and rock crawler operation.
- Easy Installation — Designed as direct replacements with standard fastening points, these arms can be installed without specialist tools or suspension rebuilds, making them ideal for weekend maintenance and repairs.
- Critical Wear Component — As stress-bearing suspension elements, upper arms are subject to flex and eventual fatigue, making spare sets invaluable for maintaining consistent handling and preventing catastrophic suspension failures during crucial driving sessions.
Technical Performance
The front upper arm set integrates seamlessly with the Super Rock Rey's sophisticated long-travel independent front suspension architecture. This suspension design incorporates king coil-over oil-filled shocks with progressive springs, dual-rate anti-sway bars, and precisely-engineered suspension arms that work together to deliver exceptional articulation, bump absorption, and steering response across rough terrain. The upper arms are critical to maintaining correct suspension geometry, particularly in high-articulation scenarios where the front wheels may be compressed or extended significantly beyond their static ride height. The 4mm 6061-T6 aluminium chassis platform of the Super Rock Rey distributes forces efficiently throughout the frame, and the front upper arms must be equally robust to handle the lateral and vertical loads imposed during high-speed runs, rock crawling, and obstacle navigation. These OEM replacement arms maintain the factory suspension geometry specifications, ensuring that your Super Rock Rey continues to deliver the responsive steering, predictable handling, and confident performance that Losi's engineering team designed into this capable ready to run RC platform. The two-piece configuration allows for straightforward left and right side installation, and the durable construction ensures longevity even under demanding use conditions typical of UK RC enthusiasts who take their vehicles off-road regularly.

Frequently Asked Questions
- What RC model does this front upper arm set fit? — This two-piece set is designed specifically for the Losi Super Rock Rey platform. The Super Rock Rey is a 1/10 scale ready to run RC rock crawler and general-purpose off-road vehicle available with various power configurations. These upper arms are designed to work with the chassis's long-travel independent front suspension system and cannot be used as direct replacements on other RC models without verification and potential modification.
- Why would I need replacement front upper arms? — Front upper arms are subject to significant stress during off-road RC driving. High-impact collisions with rocks, trees, or obstacles can bend or crack the arms, reducing suspension performance and affecting steering geometry. Worn or damaged upper arms can cause uneven tire wear, unpredictable handling, and potential suspension failures. Having genuine replacement parts ensures your Super Rock Rey maintains factory specifications and reliable performance.
- Are these genuine Losi parts? — Yes, the LOS Front Upper Arm Set is manufactured by Losi to their original equipment manufacturer specifications. When you purchase through RC Model Shop, you're receiving genuine authenticated parts with the quality assurance that comes from Losi's engineering and manufacturing standards.
- How difficult is it to install these front upper arms? — The front upper arms are designed as direct replacements that bolt directly into your existing Super Rock Rey suspension with standard RC fastening hardware. If you are comfortable performing basic maintenance on ready to run RC vehicles, you should be able to install these arms within thirty minutes to an hour using standard RC tools. However, if you are unfamiliar with suspension service, many UK RC shops offer installation services.
- What tools do I need to install these parts? — Typically you'll require a socket set or wrench set in metric sizes (common sizes include 4mm, 5mm, and 6mm), a screwdriver set, and possibly a hex key set. Your Super Rock Rey documentation will specify the exact fastener sizes required for front suspension assembly.
- How long do front upper arms typically last? — The longevity of front upper arms depends entirely on your driving style and terrain. Casual weekend drivers might go months or years before requiring replacement, whilst aggressive drivers who regularly bash through rocky terrain may need spares after just a few months of use. This is why many experienced RC enthusiasts keep spare suspension parts on hand.
- Can I use these arms with upgraded shocks or springs? — These front upper arms are engineered to work with the standard Super Rock Rey long-travel suspension geometry. If you're planning significant suspension upgrades beyond spring or shock changes, verify compatibility with the component manufacturer to ensure proper suspension angles and clearances are maintained.
