Yost Vise RHV-6 6-Inch Receiver Hitch Vise - Portable Heavy Duty

In this review the Yost RHV-6 receiver hitch vise is evaluated as a portable work vise for mechanics, fabricators, and hobbyists who need a durable solution on the road or in a small shop. The single biggest reason to buy is its flexibility: it mounts directly into a standard 2 in receiver or bolts to a bench, providing a reliable clamp with a 5.9 in jaw width and a 5.81 in maximum opening that handles most small to medium tasks without dedicated bench space.

Key Features

• Receiver hitch mount: Mounts directly into a standard 2 in trailer hitch with the included 5/8 pin so the vise can be used on a truck, trailer, or removable work station.
• Dual use: Can be bolted down to a bench for fixed use or installed in a receiver for portable work, giving true workshop and field versatility.
• Generous jaw capacity: The 5.90 in jaw width and 5.81 in maximum opening accommodate a wide range of workpieces from small parts to larger hobby projects.
• Deep throat: A 4.96 in throat depth provides reach for awkward parts and improves access for detailed or gunsmithing tasks.
• Strong clamping force: Up to 30 kN clamping force secures parts firmly for cutting, filing, and assembly operations.
• Durable construction: Made from QT450-12 ductile iron with replaceable 1045 steel jaws, it is built to withstand heavy use and wear.

Who It's For

The RHV-6 is ideal for mobile technicians, RV and truck owners, and backyard mechanics who need a robust vise that travels with the vehicle or can be quickly dropped into a trailer hitch. Its combination of a receiver mount and bolt-down option makes it well suited to those who split time between field repairs and a small workshop.

Those who need extremely large vise capacity, a full swivel base with infinite rotation, or industrial bench vises designed for heavy continuous shop production may want a different, full-size bench vise. Also, users requiring a welded pipe jaw or softer jaw faces for delicate work should plan to fit the appropriate jaw inserts or replacements.

Pros & Cons

Pros

• Portable receiver hitch mounting makes it convenient for on-the-road repairs and temporary setups.
• Solid build from ductile iron and 1045 steel jaws gives reliable durability and long-term service.
• Good jaw width, opening, and throat depth for a broad set of household, automotive, and gunsmithing tasks.

Cons

• Some users report mixed experience with long-term sturdiness under heavy daily shop use, so extreme continuous loads may reveal limitations.
• Not as large as some dedicated industrial bench vises, so very large workpieces will be constrained by the 5.81 in opening.
