Overview
Harmar Class III Heavy-Duty Hitch Adapters
A properly fitted hitch adapter is one of the most important components when installing a Harmar vehicle lift. Choosing the correct adapter ensures your mobility scooter or power chair lift sits at the proper height and distance from your vehicle, providing safe operation and preventing unnecessary stress on both your lift and vehicle.
At Affordable Medical USA, we carry genuine Harmar Class III Heavy-Duty Hitch Adapters designed specifically for Harmar mobility lifts. Whether your vehicle has a high receiver hitch, oversized bumper, rear-mounted spare tire, or requires additional clearance, there's a hitch adapter designed to provide the proper fit.
Why You May Need a Hitch Adapter
Not every vehicle has the same hitch height or rear bumper design. Trucks, SUVs, Jeeps, vans, and RVs often require a hitch adapter to correctly position a mobility lift.
A Harmar hitch adapter can help:
- Lower or raise the installed lift to the correct operating height.
- Extend the lift farther away from the rear bumper.
- Provide clearance for spare tires or oversized bumpers.
- Keep your scooter or power chair level during transport.
- Ensure your Harmar lift operates safely and as designed.
Available Class III Heavy-Duty Hitch Adapter Styles
We offer several Heavy-Duty Class III hitch adapters to fit a wide variety of vehicles.
Standard Hitch Adapters
Perfect for vehicles that only require a slight adjustment in hitch height while maintaining the standard distance from the vehicle.
Extra Long Hitch Adapters
Designed for vehicles with rear-mounted spare tires, large tailgates, deep bumpers, or where additional clearance is needed between the lift and the vehicle.
Choosing the Correct Hitch Adapter
Selecting the correct adapter requires taking a few simple measurements before ordering. Harmar uses three important measurements:
- HV – Distance from the ground to the bottom of the hitch receiver opening.
- D1 – Distance from the center of the hitch pin hole to the furthest point at the rear of the vehicle.
- D2 – Distance from the hitch pin hole toward the front of the vehicle. On many vehicles, the spare tire is the furthest forward point.
These measurements determine which adapter will provide the correct height and clearance for your specific vehicle.

Important Safety Information
Only use genuine Harmar-approved hitch adapters with Harmar vehicle lifts. Hitch extenders and aftermarket adapters are not recommended because they can affect lift performance, reduce stability, and may cause damage to your lift or vehicle. Harmar specifically advises against using non-approved hitch accessories.
Need Help Choosing the Right Adapter?
Finding the correct hitch adapter can be confusing, especially when comparing hitch heights, drop adapters, swing-away options, and extra-long models.
Our team can help you determine the correct Harmar hitch adapter based on your vehicle and lift model. Simply provide:
- Your vehicle year, make, and model
- Hitch height measurement (HV)
- Rear bumper clearance (D1)
- Whether you're using a Swing-Away attachment
We'll recommend the correct adapter before you order.
