Bulletproof Hitches Couplers/Pins & Accessories

Bulletproof Hitches Couplers, Pins & Accessories: Built to Lock Down Every Load

When you've invested in a premium adjustable hitch, the last thing you want is a weak link in the system. Bulletproof Hitches applies the same obsessive engineering that goes into their drop hitches to their Couplers/Pins & Accessories lineup — giving towers a suite of locking and connection hardware that's every bit as capable as the hitches they protect.

A Complete Security Ecosystem

Bulletproof Hitches approaches coupler and pin security as a full ecosystem rather than an afterthought. Locking pins, coupler locks, pintle locks, latch locks, and pintle attachments are all designed to work together — and can even be keyed alike. That means a single key can operate your locking pin, coupler lock, latch lock, and pintle lock simultaneously, which is a massive convenience for daily towers and fleet operators alike.

Key Products in This Category

• 5/8" BulletProof Locking Pin — Available in high-grade stainless steel or a blacked-out "Black Ops" powder coat finish, this pin features exceptional corrosion and rust resistance. It spans a 7.25-inch overall length with 4 inches of usable length, fitting 2-inch, 2.5-inch, and 3-inch hitch receivers. Anti-rattle spacers are included for 2-inch and 2.5-inch receivers, along with a safety R-clip.
• Extreme Duty Coupler Lock — Built around a 1-inch hardened solid steel bar with a pick-resistant, cut-resistant design, this lock fits all 1-7/8", 2", and 2-5/16" couplers universally. The locking mechanism is shielded by a heavy-duty rubber cap and ships with two keys.
• Extreme Duty Pintle Lock — Crafted from forged aluminum for superior corrosion resistance, this patented lock works on all size lunette rings and is treated with aircraft-grade lubricant for long-term durability.
• Latch Locks — Designed for 1-7/8", 2", and 2-5/16" couplers, featuring a straightforward threaded design for easy installation. Locks are treated with aircraft-grade lubrication.
• Pintle Attachment — Precision-made from USA steel on CNC machines, this accessory converts a dual ball setup into a functional pintle hitch, compatible with Bulletproof Heavy and Extreme Duty Hitches.

Why Bulletproof Hitches Stands Out in This Category

The entire locking product lineup is rated to 36,000 lbs, matching the load ratings of the hitches themselves — so there's no mismatch between your hitch's capacity and the hardware securing it. The keyed-alike program is also particularly useful for fleet managers and multi-trailer operators who need to simplify key management across multiple towing setups. All locking products are backed by a one-year hassle-free warranty, and the brand accommodates large quantities of locks keyed alike for commercial use.

Whether you need to secure a ball coupler, a lunette ring, or simply lock your hitch into the receiver tube, Bulletproof Hitches has purpose-engineered hardware designed to complement their own ecosystem while remaining broadly compatible with other receivers and trailers on the market.
