420motorsport. Trailer Hitches, Tow Hooks & Winches

What the parts do

A trailer hitch connects car and trailer, while wiring harnesses and adapters make sure the lights and indicators on the trailer follow the car. A brake controller regulates electric brakes on the trailer so it can brake together with the car. For recovery and towing you use tow hooks, shackles, straps and winches, and wheel chocks such as the Rhino USA Heavy-Duty Wheel Chock can hold a vehicle in place while you work. Brands in the category include GEN-Y Hitch, Weigh Safe, NRG, Rhino USA and Rugged Ridge.

How to choose a hitch and wiring

Start with the trailer's gross weight and the car's permitted towing capacity and tongue weight – the lowest figure sets the limit. Then choose mounting type and height so the trailer rides as level as possible. For the wiring, the connector type and number of pins must match both car and trailer. Whether a hitch can be approved for your car depends on the product and the car, so check the approval, e.g. E-mark, for the specific part number.

Straps, tow hooks and winches

Choose straps and tow ropes by breaking strength, width and length relative to the vehicle's weight; for example, there is the Rugged Ridge Recovery Strap 2in x 30 feet and a narrower 1in x 15 feet for ATV/UTV. Distinguish between recovery straps, which can stretch, and tie-down straps, which hold cargo in place. Tow hooks are typically mounted in an existing attachment point, and fitment depends on the car – the category includes, for example, front and rear hooks for BMW F-chassis, Toyota GR Supra (A90) and Chevrolet Corvette (C6). With winches, pulling power, line type, power draw and mounting space decide the choice; the stated maximum pull alone doesn't tell the whole story, and a good margin above the vehicle's weight is typically an advantage.

Installation and maintenance

Never pull on parts that aren't designed for the load, and use shackles and hooks with a working load that suits the job. Inspect straps for wear, cuts and sun damage, and replace them if they are damaged. Keep connectors and wiring harnesses clean and dry, and test the trailer lights before every trip. Winches and brake controllers require correct fusing and cable cross-section, so follow the manufacturer's installation instructions.

Frequently asked questions

What is the difference between a recovery strap and a tie-down strap?

A recovery strap is used to pull a stuck vehicle free and can typically stretch a little. A tie-down strap has a tensioning mechanism and holds cargo in place on a trailer or truck bed. Don't use one for the other's job.

Does a trailer hitch need to be approved or inspected?

It depends on the product and the car. Check whether the specific part number has the necessary approval, e.g. E-mark, and whether the installation needs to be registered or inspected. Also check the car's permitted towing capacity and tongue weight.

Can a tow hook be used for off-road recovery?

It depends on the hook and the mounting. Some tow hooks are designed for towing on the track or road, while recovery can produce much stronger jerks. Check the manufacturer's load rating for the specific product.

When do I need a brake controller?

Typically when the trailer has electric brakes that need to be controlled from the car. The brake controller regulates the braking force on the trailer. Check that it suits the trailer's brake system and the car's electrics.
