BIG RED 2 Pack Hitch Lock Pin 5/8" Trailer Receiver Locking Pin for 2"/2.5" Receivers — Hardened Steel, Chrome-Plated Anti-Theft

Big RED 2 Pack Hitch Lock Pin is a heavy-duty, 5/8-inch diameter locking pin designed to secure 2" and 2.5" trailer receiver tubes for dependable anti-theft protection when towing.

If you tow trailers, boats, RVs or carry accessories on a receiver, the connection point between hitch and vehicle is a common theft and safety concern. These Big RED hitch pins combine hardened steel construction, chrome plating, and a keyed locking head to keep a trailer or hitch accessory secured while resisting bending, rust, and unauthorized removal. This two-pack delivers spare or backup pins and two keys per lock for daily towing and long-term storage needs.

How durable is this hitch pin for heavy towing?

The Big RED pin uses hardened steel and a rugged chromed finish to withstand road stresses and resist corrosion in wet or salty conditions. Its 5/8" diameter and solid core reduce risk of bending under typical loads, making it suitable for Class III/IV receivers.

• 5/8" diameter solid steel core for strength against shear forces
• Chromed plating for corrosion resistance in outdoor use
• Meets ANSI/ASME PASE safety standards for added reliability

Will it fit my trailer receiver and accessories?

This lock pin is sized for common receiver tubes: it fits both 2" and 2.5" receivers used on many Class III and IV hitches. The effective pin length gives enough reach to pass through receiver and accessory holes while securing the assembly with the locking head.

• 5/8" diameter pin fits standard receiver hitch holes
• 3.54" effective pin length for most hitch and accessory combinations
• Works with trailers, ball mounts, bike racks and other receiver accessories

How easy is it to lock and unlock when hooking up or storing?

Operation is straightforward: insert the pin through the receiver and accessory, press the locking head until it clicks and then use the key to secure it. The head rotates 360 degrees for easier alignment and the design pops the pin when unlocked for quick removal.

• Keyless push-to-lock action signals with an audible "click"
• Turn 1/4 clockwise with the key to unlock and release automatically
• 360-degree rotating head aids in alignment and ease of use

What features protect the lock from weather and tampering?

Big RED includes weather-focused details to extend service life in wet, dusty, or coastal environments. A rubber cover shields the key slot from moisture, and the chrome plating plus zinc alloy components improve resistance to rust and simple forced attacks.

• All-weather rubber key slot cover prevents dust and moisture ingress
• Zinc alloy keyhole components enhance anti-theft performance
• Chromed finish reduces surface corrosion from road salt and rain

It’s aimed at boat owners, RV travelers, landscapers, fleet operators and anyone who attaches bike racks, cargo carriers or trailers to 2" or 2.5" receivers and needs a durable anti-theft option. The two-pin set and included keys provide a backup for multiple vehicles or a spare for storage, and the ANSI/ASME PASE compliance plus one-year limited warranty make it a practical choice for both occasional and frequent towing.
