All Aluminum Extension Arm Kit for GoPro and Action Cams - Stable

In this review of the All Aluminum Extension Arm Kit, the bottom line is simple: this kit is for action cam users who want a lightweight, rustproof way to extend and reposition their camera for helmets, poles, or handheld rigs. The review finds the biggest reason to buy is its durable aluminum construction combined with multiple arm lengths, which gives practical flexibility for skiing, cycling, or skateboarding shots while keeping wind drag down thanks to a hollow design.

Key Features

• All aluminum construction: The arms and screws are made from aluminum alloy, so the kit resists rust and feels rugged without adding much weight to a helmet or pole.
• Three arm lengths: Including 11.8 in, 6.5 in and 3.3 in sections lets users build a range of reach and framing options for close-up or extended shots.
• Standard screw holes: 1/4 in and 3/8 in threaded holes make it easy to attach common tripods, mounts or expansion accessories without adapters.
• Hollow, aerodynamic design: The hollow profile reduces wind resistance when mounted on helmets or poles, improving stability while riding at speed.
• Complete hardware kit: The set ships with three aluminum screws and a wrench to tighten connections for a more secure assembly in the field.

Who It's For

This kit is best for outdoor action photographers and videographers who use GoPro Hero 13/12/11/10/9/8/7/6/5, DJI Osmo Action and similar cameras and need a durable, lightweight way to extend camera reach or build a compact pole or stabilizer. It suits riders, skiers, and skateboarders who want multiple mounting lengths and the option to attach standard accessories.

Users who need vibration-isolating gimbals or full damping for high-speed highway use should look elsewhere, since the kit provides rigid aluminum connections and some customers report movement at very high speeds. It is not a powered or motorized stabilizer; consider electronic gimbals for extreme shake reduction.

Pros & Cons

Pros

• Strong, rustproof aluminum build that balances durability and low weight.
• Multiple arm lengths and standard 1/4 in and 3/8 in holes for flexible accessory mounting.
• Hollow design reduces wind drag and helps maintain steadier shots in typical outdoor use.
• Includes screws and a wrench so the kit is ready to assemble without extra tools.

Cons

• At highway speeds some users report the assembly can shift, so it may need frequent retightening for extreme high-speed use.
