Mopar hitch receiver adapter for Dodge Ram 2500/3500 — 2½

This Mopar OEM hitch receiver adapter converts a factory 2½-inch receiver to accept standard 2-inch tow accessories on 2013–2016 Dodge Ram 2500 and 3500 trucks.

When your Ram came from the factory with a 2½-inch receiver, many commonly available ball mounts, bike racks and cargo carriers won’t fit without an adapter. This genuine Mopar part (PN 68165918AA) provides a direct-fit, factory-quality solution engineered for the 2013–2016 Ram 2500 and 3500 platforms. Made in the United States, it preserves the original fit and finish while letting you use the more common 2-inch hitch accessories without modifying the truck.

How does the adapter install and fit my Ram?

Installation is straightforward: slide the Mopar adapter into the factory 2½-inch receiver and secure it with the hitch pin or locking device you already use. Because this is an OEM part designed for the truck, alignment and fit match the receiver geometry so no trimming or fabrication is required.

• Fits factory 2½-inch receiver on 2013–2016 Dodge Ram 2500/3500
• Slides into receiver and secures with standard hitch pin or lock
• OEM dimensions matched to original receiver tolerances
• No drilling or modification needed for installation

What towing or accessory options will this adapter allow?

By reducing the receiver opening from 2½ inches to 2 inches, this adapter lets you use the vast majority of aftermarket ball mounts, cargo carriers, bike racks and other 2-inch accessories. It’s intended for adapting accessory fitment rather than changing the truck’s engineered towing capacity—always consult your owner’s manual and accessory ratings.

• Accepts standard 2-inch shank accessories like hitches and racks
• Compatible with common towing accessories and cargo solutions
• Ideal when you own 2-inch equipment and a 2½-inch receiver
• Use accessory-rated pins and locks for secure attachment

As a factory Mopar component, the adapter is manufactured to OEM quality standards with durable metal construction and corrosion-resistant finishes appropriate for towing hardware. The part is produced in the United States and carries the Mopar part number 68165918AA for easy reference when ordering replacements or confirming fitment.

• Heavy-gauge steel construction for structural strength
• Factory surface finish to resist rust and wear
• Made in the United States to Mopar specifications

Are there safety or capacity considerations I should know about?

The adapter changes only the receiver aperture size, not the vehicle’s rated towing or tongue weight capacity. Always verify the combined ratings of the adapter, the vehicle’s hitch, and the accessory being used. Use the correct-size hitch pin or locking device and inspect connections routinely for wear or corrosion.

• Adapter does not increase factory towing capacity
• Match adapter and accessory ratings to vehicle towing limits
• Secure with appropriate hitch pin or lock and torque to spec
• Perform regular inspections for corrosion or damage

Who is this for: This Mopar 2½- to 2-inch hitch receiver adapter is for Dodge Ram 2500 and 3500 owners (model years 2013–2016) who want to use 2-inch tow accessories with the factory 2½-inch receiver. It’s especially useful for drivers who already own 2-inch ball mounts, bike or cargo racks and prefer an OEM-quality, bolt-in style solution rather than an aftermarket workaround. If you need to confirm fitment or towing ratings for specific loads or accessories, consult your vehicle owner’s manual or a qualified towing professional.
