HAIBOXING RC Car Upper/Lower Suspension Arms Full Set - Direct Fit

In this review of the HAIBOXING RC Car Upper/Lower Suspension Arms full set, the bottom line is simple: this is a practical, direct-replacement kit for owners of HBX 903, 903A and 905 models who need reliable suspension hardware without modifying the chassis. The reviewer found the set straightforward to install and appreciated that it is an original spare part option labeled for numbers 90113, 90117 and 90118, which makes sourcing the correct parts easier. For hobbyists who want a one-stop replacement for both front and rear upper and lower arms plus hinge pins, this set delivers the fit and parts count expected from a matched OEM kit.

Key Features

• Original spare part: The set is sold as original manufacturer parts, which helps ensure compatibility and reduces trial-and-error when replacing breakable suspension pieces.
• Complete set: It includes both front and rear upper and lower suspension arms plus the hinge pins, so a single purchase covers most common suspension repairs on supported models.
• Model compatibility: Designed to apply to HBX 903, 903A and 905 models, so buyers of those trucks can expect parts to match mounting points and geometry.
• Clear part numbers: Marked with spare part numbers 90113, 90117 and 90118, making it easier to confirm the right replacement when cross-referencing manuals or parts lists.
• Quantity as a set: The kit ships as a complete set rather than individual pieces, which is convenient for repairing both sides and both axles at once.

Who It's For

This kit is best for HBX owners who maintain their 903, 903A or 905 models and prefer using original spare parts for a consistent fit. It suits weekend racers, hobbyists doing routine maintenance after crashes, and anyone rebuilding a damaged suspension without wanting to hunt for separate arms and pins.

Those who should look elsewhere are owners of different chassis or aftermarket custom builders seeking performance-upgrade materials; this is a replacement parts set focused on direct fit and restoration rather than upgraded strength or altered geometry.

Pros & Cons

Pros

• Comprehensive replacement: includes both upper and lower arms for front and rear plus hinge pins, covering most repair scenarios.
• Original parts: labeled as original spare parts which helps ensure correct fit on compatible HBX models.
• Clear compatibility: explicitly applies to HBX 903, 903A and 905, reducing uncertainty when ordering.
• One-purchase convenience: sold as a set so buyers avoid multiple orders for related components.

Cons

• Not an upgrade: the set is intended as direct replacements rather than higher-performance or reinforced parts.
• Limited model range: only compatible with the listed HBX models, so it is not universal across other truck lines.
