Overview

The HOBAO HYPER SS CAGE TRUGGY CNC REAR LOWER ALUM. ARM HOLDER is a precision-engineered suspension component designed for serious RC enthusiasts looking to fine-tune their 1/8 scale electric truggy. This CNC-machined aluminium arm holder is an essential upgrade for the HOBAO Hyper SS and Cage truggy platforms, allowing you to adjust your rear suspension geometry with three distinct hop-up angles: 2 degrees, 3 degrees, or 4 degrees. Whether you're a competitive racer seeking that perfect setup, a weekend basher optimising your vehicle's handling characteristics, or an experienced RC driver in the UK exploring advanced tuning options, this component delivers the precision adjustability that serious RC enthusiasts demand.

The CNC manufacturing process ensures absolute accuracy and consistency, eliminating manufacturing tolerances that can affect suspension performance. This rear lower arm holder represents HOBAO's commitment to quality engineering and is engineered to work seamlessly with the Hyper SS and Hyper SST chassis platforms. If you're serious about maximising your RC truggy's performance on both track and off-road environments, this is the kind of precision upgrade that separates competitive setups from standard builds. This component is manufactured to the exacting standards you'd expect from a manufacturer with HOBAO's reputation in the RC car UK market.

Available now at RC Model Shop, this is an ideal choice for anyone looking to upgrade their HOBAO Hyper SS or Cage truggy suspension geometry. The ability to select between three different arm angles means you can dial in the exact suspension characteristics your driving style requires, whether that's more aggressive cornering angles for racing, or more stable geometry for general bashing and practice sessions.

Key Features

• CNC-Machined Aluminium Construction — Precision computer-controlled manufacturing ensures each arm holder is produced to exact specifications with zero tolerance for deviation, guaranteeing perfect fitment and consistent performance across your RC setup. This manufacturing method is far superior to traditional casting or moulding techniques.
• Three Adjustable Geometry Options — This component provides three distinct installation angles (2°, 3°, and 4° hop-up angles), allowing you to completely customise your rear suspension geometry to suit your driving style, track conditions, and performance preferences without requiring additional parts or modifications.
• Lightweight Aluminium Material — Aluminium construction keeps unsprung weight to an absolute minimum while maintaining structural rigidity, which directly improves suspension response, handling precision, and overall vehicle dynamics during aggressive driving or racing.
• Direct Compatibility — This component is engineered specifically for the HOBAO Hyper SS and HOBAO Hyper SST Cage electric truggy platforms, ensuring perfect fitment and performance without modification or adaptation required.
• Professional-Grade Upgrade — This is the type of precision component you'll find in competition-winning setups, making it ideal for drivers who understand that small geometry adjustments can make significant differences in handling, cornering grip, and overall vehicle performance.

Technical Performance

This CNC rear lower arm holder represents the kind of precision engineering that separates quality RC components from budget alternatives. Manufactured from high-grade aluminium using computer numerical control (CNC) machinery, every dimension is produced to exacting tolerances that ensure consistent performance and perfect fitment every single time. The three available hop-up angles (2°, 3°, and 4°) allow you to fine-tune your rear suspension's anti-squat characteristics, camber angles, and overall handling bias. By adjusting the arm geometry, you can modify how your truggy's suspension responds under acceleration, braking, and cornering forces. This level of adjustability is particularly valuable for drivers who compete or who want to optimise their vehicle across different track surfaces and weather conditions. The lightweight aluminium construction minimises unsprung weight at the rear axle, which improves suspension articulation and allows the shock absorbers to respond more quickly to terrain changes and driving inputs. For drivers using the HOBAO Hyper SS or Hyper SST Cage platforms, this upgrade provides measurable improvements in handling precision, corner exit grip, and overall vehicle stability during high-speed driving or technical courses. Quality matters in RC, and CNC-manufactured components like this deliver the kind of precision you simply cannot achieve with injection-moulded plastic or standard cast metal parts.

Frequently Asked Questions

• What is an arm holder and why do I need to upgrade mine? — The arm holder is the structural component that connects your lower suspension arm to your truggy's chassis. Upgrading to a CNC-machined version improves precision, durability, and most importantly, allows you to select from multiple geometry angles to fine-tune your suspension performance. This is essential if you want to optimise your vehicle's handling for specific conditions or competitive racing.
• Which HOBAO models does this fit? — This component is designed specifically for the HOBAO Hyper SS and HOBAO Hyper SST Cage electric truggy platforms. Before purchasing, verify that your model matches one of these platforms to ensure perfect compatibility.
• What difference will changing the arm angle make to my truggy? — The angle of the rear lower arm significantly affects anti-squat geometry, rear camber during acceleration, and overall suspension response. A 2° angle provides different handling characteristics compared to 4°. Most drivers will notice increased cornering grip and improved stability with certain angles depending on their specific setup and driving style. Experimentation is key to finding your optimal angle.
• Is this a bolt-on upgrade, or do I need to modify my chassis? — This is a direct replacement component that uses your existing mounting points on the HOBAO Hyper SS or SST Cage chassis. No chassis modification is required, making installation straightforward for anyone with basic RC maintenance skills and appropriate tools.
• Why is CNC manufacturing important for RC parts? — CNC manufacturing eliminates human error and manufacturing tolerance variations. Every single component is produced to identical specifications, ensuring consistent performance and perfect fitment. This is particularly important for suspension geometry, where even small deviations can affect handling and performance.
• Can I use this with other RC truggy brands? — No, this component is engineered specifically for HOBAO Hyper SS and Hyper SST Cage models. Using it on other platforms would require significant modifications and would void any warranty. Always verify your platform compatibility before purchasing any suspension upgrade.
