Key Features

• Genuine HoBao OEM Component — This is an authentic factory-original part manufactured by HoBao, ensuring perfect compatibility and meeting the exact same engineering standards used in all HoBao Hyper SS and Cage vehicles. Using genuine spares maintains your vehicle's performance and reliability over the long term.
• Aluminium Construction — The arm holder is machined from lightweight yet rigid aluminium alloy, providing the perfect balance between weight savings and structural integrity that competitive RC racing demands. Aluminium also resists corrosion better than steel, making it ideal for outdoor use across UK weather conditions.
• B-Plate Configuration — The B-plate geometry specification allows drivers to adjust suspension characteristics and fine-tune handling response. Different plate configurations (A, B, C, D) provide alternative mounting angles, giving you flexibility in suspension setup and the ability to optimise performance for different driving styles and track conditions.
• Rear Lower Suspension Mounting — This component serves as the critical lower mounting point for your rear suspension arms, directly influencing ride height, anti-squat geometry, and overall suspension compliance. Proper suspension geometry is essential for consistent handling and competitive lap times.
• Direct HoBao Hyper SS Compatibility — Engineered specifically for the HoBao Hyper SS 1/8 scale electric and nitro buggy platforms, this part guarantees seamless fitment without modification or adaptation required. Full compatibility extends across both electric (HoBao SSe) and nitro-powered variants.
• Direct HoBao Hyper Cage Compatibility — Also designed for the HoBao Hyper Cage buggy and truggy platforms, this single part serves multiple models in the Cage lineup, making it an essential spare for owners running any variant of these popular vehicles.
• Extended Truggy Compatibility — Beyond buggy models, this arm holder also fits HoBao's 1/8 scale Hyper SSTe and Cage truggy platforms, providing even broader utility and making this a valuable spare for serious HoBao enthusiasts running multiple vehicle types.
• Precision Machining — The component is precision-machined to ensure exact dimensional accuracy, consistent fit with other suspension components, and reliable performance under the demanding loads generated during high-speed racing and aggressive driving.
• Direct Replacement Part — If your original arm holder becomes damaged, bent, or worn through normal use, this genuine HoBao replacement restores your suspension to factory specifications without any compatibility issues or fitment concerns.

Technical Performance

The HoBao Hyper SS/Cage Rear Lower Aluminium Arm Holder-B Plate represents precision engineering optimised for competitive 1/8 scale RC buggy and truggy racing. Constructed from high-grade aluminium alloy, this component combines lightweight design with exceptional rigidity, crucial characteristics for maintaining precise suspension geometry during high-speed cornering, braking, and acceleration events. The B-plate configuration is one of several geometry options available, allowing experienced drivers to dial in suspension characteristics suited to their specific driving technique and local track conditions. The aluminium material selection provides excellent corrosion resistance, important for UK climate conditions involving moisture and humidity exposure, whilst maintaining superior stiffness compared to plastic alternatives. This arm holder directly interfaces with your rear lower suspension arms and mounting hardware, making it a critical load-bearing component that must resist flexing and maintain consistent angles throughout aggressive driving sessions. The precision machining ensures tolerances tight enough for competitive use, where even small deviations in suspension geometry can noticeably affect handling balance, turn-in response, and exit traction. When combined with corresponding upper arm holders and suspension linkages, this component contributes to the overall suspension kinematics that determine how your HoBao Hyper responds to track obstacles, bumps, and driver inputs. Whether running on the grass fields of UK RC racing clubs or challenging outdoor terrain, this aluminium component delivers the durability and dimensional stability expected from genuine OEM parts engineered by HoBao's R&D team.

Frequently Asked Questions

• Which HoBao Hyper models does this rear lower arm holder fit? — This part is fully compatible with the HoBao Hyper SS 1/8 electric buggy, HoBao Hyper SSe brushless variant, HoBao Hyper Cage buggy in both electric and nitro versions, and the 1/8 scale Hyper SSTe and Hyper SS Cage truggy platforms. It works with models including the HBCB-C28B (Cage RTR Mach 28 Black), HBCB-C28RG (Cage RTR Orange), HBSS-C28B (SS RTR Mach 28), HBSS-C21B (SS RTR Hyper 21), HBSSE-C100B (SSe electric RTR Black), HBSSE-C100BU (SSe electric RTR Blue), HBSST-C28RG (SS Nitro Truggy), HB-SSTE-C150RG (SSTe brushless truggy), and HBCT-C28B (SS Cage Nitro Truggy). If you own any of these models, this genuine HoBao spare part is a direct fit.
• Is this a genuine HoBao part or a aftermarket replacement? — This is a genuine original equipment manufacturer (OEM) part manufactured by HoBao to exact factory specifications. The part number H90017 is the official HoBao designation, and purchasing genuine parts ensures you receive components engineered and tested to the same standards used in HoBao's production vehicles. Genuine spares also provide better warranty coverage and reliability.
• What is the difference between the A-plate, B-plate, C-plate, and D-plate configurations? — HoBao offers multiple plate configurations (A, B, C, D) for the rear lower arm holder, each providing slightly different suspension geometry angles. The different plates allow drivers to adjust anti-squat geometry, ride height characteristics, and suspension compliance to suit their driving style, local track conditions, or weather-related grip levels. The B-plate is a mid-range geometry specification. Competitive drivers often experiment with different plate configurations to find the optimal setup for their specific car and driving technique.
• Do I need to replace this part regularly, or is it a one-time component? — Under normal use, this aluminium arm holder should last many years without replacement. However, it may need replacing if you crash heavily and damage the mounting bosses, if it becomes bent in a high-impact accident, or if mounting threads become stripped from repeated assembly and disassembly. Keeping a spare arm holder on hand is sensible for serious racers who attend competitions regularly.
• Can I use this part on other RC car brands besides HoBao? — No, this component is specifically engineered for HoBao Hyper SS and Cage platforms and will not fit other brands or models. The mounting geometry, hole spacing, and interface dimensions are unique to HoBao's suspension design. Using the correct OEM part ensures proper fitment and performance.
• What tools do I need to install this rear lower arm holder? — Installation requires basic RC car tools including hex keys (Allen wrenches) in sizes appropriate for your HoBao hardware, a screwdriver if your model uses screws, and possibly a small wrench for suspension ball ends and hardware. Consult your HoBao Hyper SS or Cage instruction manual for detailed assembly diagrams and recommended hardware torque specifications. No special tools are typically required.
• Is this compatible with both electric and nitro-powered HoBao Hyper models? — Yes, this rear lower arm holder is compatible with both electric-powered variants (HoBao SSe, HBCBE, HBSSE) and nitro-powered models (HBSS-C21B, HBSS-C28B, HBCB-C28B, HBSST-C28RG, HBCT-C28B). The suspension geometry is identical across both powertrains, so one part serves both engine types across the compatible model range.
