RockyMounts 8-in Trailer Hitch Extension for 2-in Receivers with Lock

Overview

The RockyMounts 8-in Trailer Hitch Extension adds eight inches of reach from a standard 2-in receiver, giving your bike racks extra clearance for spare tires, rear doors, or bumper detours. It’s designed to work with popular RockyMounts racks—Backstage, Monorail, and Split Rail—and it also performs well with many third-party bike racks from Thule, Yakima, and Kuat.

With this extension, you can position racks where you need them most without sacrificing functionality. The setup prioritizes utility and simplicity, helping you tailor your cargo space for different vehicle profiles and loads while keeping equipment stable on the road.

Key Benefits

• Extends the rack 8 inches from the hitch, increasing clearance around spare tires and rear doors.
• Designed for 2-inch hitch receivers for broad compatibility with common vehicles.
• Includes a locking anti-wobble hitch pin to improve stability and security during travel.
• Lightweight design at roughly 10 lbs, making installation and handling easier.
• Ideal for vehicles with recessed hitches, spare tires, or doors that hinge near the rack area.
• Note: the extension reduces the rated weight capacity by about 50% to accommodate the longer reach.

Use Scenarios

• Urban garages and driveways where space is tight, allowing racks to fold without contacting the spare tire.
• Road trips with vans, SUVs, or trucks that have rear doors or exterior spare tires, preventing rack interference.
