TowWorks 79852 Keyed Alike 5/8″ Trailer Hitch Lock Set for Adjustable Channel Mounts, Double Safety Heavy Duty Tow Hitch Receiver Locking Pins fit Class III – V Hitches
This set stands out for its compatibility with most adjustable hitches, including channel style and pintle hooks, making it highly versatile. The inclusion of rubber O rings and a spring clip adds safety and reduces rattling, which is a thoughtful touch compared to simpler locks. Its keyed alike feature simplifies management of multiple locks, and the push lock design ensures ease of use. However, it does not fit Fastway adjustable hitches, which could limit its applicability for some users. Compared with other options like the MaxxHaul 50151, this set offers broader compatibility, but the latter might be easier for quick install without verifying dimensions first. This pick makes the most sense for those needing a reliable, all-around adjustable hitch lock, willing to check dimensions beforehand.

MaxxHaul Hitch Pin Lock Set 2 Hitch Pins 1/2″ and 5/8″ with 1 Shared Lock Keyed Alike Anti-Theft Trailer Hitch Lock for Class I-V Receivers Weatherproof (50151)
This set offers excellent value by including two different sized pins—1/2″ and 5/8″—making it suitable for a range of trailer receivers. Its construction from corrosion-resistant steel with rubber O rings ensures quiet operation and durability in harsh weather, outperforming many basic locks. The keyed alike feature simplifies key management, and the weatherproof rubber cap protects the lock from elements. The main tradeoff is that the lock cap does not automatically lock when pressed, requiring careful use to avoid accidental unlocking. Compared with the Orion Motor Tech lock, this set provides dual sizes but may lack the quick installation features of some more advanced models. This set is best for budget-conscious buyers needing versatile, weather-resistant locks for multiple receiver sizes.
Pros:- Includes two sizes: 1/2″ and 5/8″ pins for broad compatibility
- Weatherproof rubber cap and corrosion-resistant steel construction
- Keyed alike for simple key management
- Rubber O rings reduce rattling and noise

TowWorks 79633 Keyed Alike 5/8″ Trailer Hitch Lock Set with Extra Long 3-1/4″ Span, Double Safety Tow Hitch Receiver Locking Pin for Class III IV Hitches with 2″ and 2.5″ Receivers, 3-Pack
This set is distinguished by its extra-long 3-1/4″ span, making it suitable for heavy-duty applications and thicker receiver tubes like those on Gen-Y hitches. The keyed alike feature simplifies key management for multiple locks, and the rubber O rings help minimize rattling. Its construction from steel and zinc alloy ensures durability, and the 1/4 turn push lock design makes it relatively easy to operate. However, the extra length limits compatibility with some hitch types, such as the Gen-Y ball mount, unless you remove O rings, which may reduce rattle prevention. Compared to the Orion Motor Tech lock, this set emphasizes strength and length over quickness or universal fit. It’s ideal for heavy-duty users needing longer pins for thicker receivers, but not for those with tight space constraints.
Pros:- Extra-long 3-1/4″ span for heavy-duty and thicker receivers
- Keyed alike for simplified key management
- Durable steel and zinc alloy construction
- Rubber O rings reduce rattling
Cons:- Extra length may not fit all hitch types, such as certain Gen-Y units

This pick excels in ease of use—installing in seconds with a twist of the aluminum cap and providing triple locking via drilled holes and an R-clip. The durable 40Cr steel pin, combined with O rings, effectively dampens vibrations and noise, outperforming basic pins that rattle. Its 7.3-inch total length fits all 2-inch receivers snugly and offers strong tamper resistance thanks to a cam locking system with keyed alike options. The electrophoretic coating ensures resistance to rust and corrosion, making it suitable for diverse weather conditions. A notable tradeoff is that it’s specifically designed for 2″ receivers, limiting its use with larger or different-sized hitches. Compared to the MaxxHaul 50151 set, this model emphasizes quick installation and anti-rattle features, ideal for frequent hitching and unhitching.
Pros:- Quick slide and twist installation for effortless use

Its spring clip provides quick safety backup, and rubber O-rings minimize rattling—features that enhance security and durability. Compared to the Rhino USA 2″ Hitch Pin, TowWorks offers better fit versatility for adjustable and larger receivers.

Its 4.5″ span fits multiple receiver sizes, with anti-rattle rubber O-rings for quiet operation. The stainless steel construction offers superior durability over the steel & zinc alloy used in TowWorks, especially in harsh weather conditions.
