This is a grooved style 5/8-inch hitch pin designed for 2-inch square receivers, built for ATV and UTV setups as well as a wide range of light- to mid-duty hitch applications. It ships with a retaining R-clip for quick, tool-free installation and dependable engagement, giving you peace of mind on rough trails and work sites. The grooved head improves retention, helping prevent wobble and loosening under vibration when you’re bouncing over rocks or plowing through mud.

Unlike a plain pin, the grooved design creates a more secure seating in the receiver, so attachments stay firmly in place through repeated on/off cycles and rough terrain. The included R-clip offers a simple, reliable locking method that resists accidental withdrawal during travel. This aftermarket replacement delivers rugged, cost-effective performance for ATV/UTV trailers, utility carts, and other common 2" hitch systems where reliable pin retention matters. It’s compact enough to carry as a spare in your toolkit, yet sturdy enough for frequent assembly and disassembly on the trail or the farm.

Typical applications include 2" square receivers on ATVs, UTVs, and light trailers, with a 5/8" pin diameter being the standard across major brands.

Comprehensive Fitment

Notes: 2" square receivers are a universal standard across many consumer and utility vehicles, and the 5/8" pin diameter is the common size for those openings. References from major hitch brands confirm the 2" receiver and 5/8" pin sizing used in ATV/UTV and trailer setups.

Product Specifications

What's Included

Includes the essential components needed to secure a 2" square receiver attachment:

• R-clip

Note: The hitch receiver itself and any mating hardware shown in product photos are not included.

Why Choose This Aftermarket Replacement?

• Direct-Fit Compatibility: Designed for 2" square receivers, matching the standard hitch sizing on ATVs, UTVs, and light trailers.
• Premium Materials: High-strength steel with zinc plating for durability in rugged outdoor use.
• Grooved Retention: Grooved head improves seating and reduces loosening under vibration and repeated attach/detach cycles.
• Included Retention Clip: R-clip provides a quick, tool-free lock that resists accidental withdrawal.
• Compact, Reliable: A practical spare for your toolkit that stands up to frequent assembly and disassembly on the trail or farm.

Installation Notes:

• Verify fitment: Confirm the vehicle’s receiver is a 2" square opening and the pin hole accepts a 5/8" diameter pin before installation.
• Groove alignment: Align the groove with the receiver’s hole so the head seats fully and the R-clip can engage without burrs.
• Clean the channel: Remove dirt, debris, and rust from the receiver and pin to ensure smooth seating and retention.
• Install the R-clip last: Push the pin fully into the receiver, then snap the R-clip into the groove to secure the pin.
• Torque and load considerations: This is a shear-pin-style engagement; do not exceed the recommended hitch load limits for your setup.
• Inspection routine: Periodically inspect for corrosion or bending; replace if the groove or pin body shows wear or deformation.

Why Upgrade?

Running a worn or loose hitch pin can let attachments wobble, slip, or even detach, creating safety hazards on the trail or jobsite. Replacing with this grooved, 5/8" pin restores secure engagement and consistent retention, maintaining reliable attachment of your trailer, rack, or implement. The upgrade reduces vibration-induced loosening and improves overall hitch performance in rugged conditions.
