MaxxHaul Hitch Mount Truck Bed Extender and Heavy Duty Hitch Lock

In this review the MaxxHaul 70231 bed extender paired with the 70050 hitch lock is assessed for truck owners who need a simple, sturdy way to carry long loads. The bottom line: this combination is for people who regularly haul ladders, kayaks or lumber and value a heavy gauge steel extender that fits 2 in receivers and a dependable chrome locking pin that resists wear. Together they extend cargo capacity and secure the receiver with practical features aimed at frequent use.

Key Features

• Extendable bed support: The 70231 extends the truck bed to carry longer payloads like kayaks and lumber while keeping loads stable.
• Adjustable fit: Adjustable length and width provide versatility for different cargo types and mounting configurations.
• Quick assembly: Four quick release clevis pins let you install or remove the extender fast without tools.
• Visibility and safety: Reflective tape and a red flag increase visibility of extended loads for safer transport.
• Secure locking pin: The 70050 trailer hitch lock fits class III/IV 2 in receivers and locks only after the key is removed, preventing accidental locking.
• Durable finish: Double chrome plating and a diamond knurled finish improve corrosion resistance and handling for the hitch lock.

Who It's For

This kit is best for DIYers, contractors, and outdoor enthusiasts who regularly haul long items such as ladders, 16 ft kayaks, pipes, or lumber and need a reliable, budget-conscious solution that installs quickly. The extender supports up to 300 lb, so it fits light to moderate hauling tasks without needing a larger trailer.

Those who should look elsewhere include drivers who need a solution for extremely heavy commercial payloads well above 300 lb or users seeking a folding or permanently-mounted factory-style rack; this unit is designed for removable, occasional heavy use rather than permanent heavy-duty towing infrastructure.

Pros & Cons

Pros

• Simple, solid steel construction gives a feeling of quality and stability for long loads.
• Easy to assemble and remove thanks to the four quick release clevis pins.
• Hitch lock adds a secure, corrosion-resistant locking option with a practical design that prevents accidental locking.
• Reflective tape and a red flag improve safety when carrying oversized loads.

Cons

• The 300 lb load capacity limits use to light or moderate loads and is not suitable for heavy commercial hauling.
• Because it is an external bed extender, users who want a permanent, sleek factory rack may prefer a different solution.
