Let's Go Aero Trailer Hitch Pin

Let's Go Aero Silent Hitch Pin®: Redefining the Trailer Hitch Pin

Most tow-vehicle owners accept a certain amount of hitch clatter as an unavoidable fact of life — that metallic banging every time you hit a bump or ease off the throttle. Let's Go Aero, a Colorado-based outdoor lifestyle and towing accessory company, set out to solve that problem permanently with its patented Silent Hitch Pin® lineup. What started as a niche fix for a universal annoyance has grown into one of the most recognizable innovations in the trailer hitch pin category.

How the Silent Hitch Pin® Works

Standard hitch pins simply pass through the receiver and rely on a clip or cotter pin to stay in place, leaving tolerances that allow the shank to rattle freely. Let's Go Aero takes a fundamentally different approach. The patented technology adds compression to the interior of the hitch receiver using a steel coiled spring nut that threads onto the pin and locks tight against the tow accessory shank — effectively eliminating all excess space and removing the root cause of noise-causing friction. The result, as Let's Go Aero calls it, is Safe and Silent Towing®.

The pin shaft itself is constructed from 4140 cold rolled steel with a heavy chrome finish, while the spring nut receives a hot-dip zinc galvanized treatment that both inhibits corrosion and naturally self-lubricates the threads over time — a practical detail that matters for tow rigs exposed to road salt, rain, and mud.

Product Lines & Receiver Compatibility

Let's Go Aero offers Silent Hitch Pin® models across a range of receiver sizes and hitch classes, ensuring tow-vehicle owners from light-duty commuters to heavy-hauling truck drivers can find the right fit:

• Class I (1.25" Receiver): The lockable 1/2" Silent Hitch Pin removes noise and free-play from Class I connections, ideal for bicycle racks and small ball mounts.
• Class II–IV (2" Receiver): The flagship SHP2040 and SHP359 models feature a 5/8" threaded pin rated up to Class IV (12,000 lbs max tongue weight), compatible with any hollow-shank 2" tow accessory.
• XL (2.5" Receiver): Designed for newer GM and large-body Toyota vehicles with thicker receiver side walls.
• XXL (3" Receiver): The extra-long model spans a full 4.375" to accommodate the latest 3" GM and large-body Toyota hitches, featuring a 90-degree heavy-duty lock with a nylon jacket and rubber dust cover.

Locking Security Built In

Beyond eliminating rattle, many Silent Hitch Pin® variants integrate a robust weather-proof barrel lock — complete with rubber dust cap and stainless steel keys — that prevents the removal of any hollow tow device attached to the receiver. This dual function of anti-rattle performance and theft deterrence is central to what sets Let's Go Aero apart from commodity hitch pins. Multiple Silent Hitch Pins purchased together can also be keyed alike for single-key convenience across a fleet of tow accessories.

Transferable & Versatile

One of the more practical design features is transferability: the spring nut assembly moves easily between any hollow-shank 2" accessories — ball mounts, cargo carriers, bike racks, or hitch steps — so a single Silent Hitch Pin® investment serves your entire hitch accessory collection. It is worth noting that the pin requires a hollow (not solid) tow accessory shank to function correctly, so confirming shank type before purchasing is essential.

Whether you are towing a trailer across the country or simply running a bike rack around town, a quality trailer hitch pin makes every mile quieter and more secure.
