A hitch turns your ML320 into the one that takes a bike rack, a cargo carrier, a utility trailer or a small boat. CURT builds two hitches for the Mercedes ML320 from 1998 to 2008, Class 3, rated 3,500 lb to 3,500 lb, from $495.03 CAD with free shipping anywhere in Canada.

CURT parts for the Mercedes ML320
Wiring, ball mount and the rest
A bike rack needs nothing but the hitch. A trailer needs lights, and the wiring guide walks you through four-flat and seven-way for the ML320.
Then a ball mount sized to the receiver: CURT 45836 ($41.70 CAD) drops straight into a 2-inch receiver. Pick the drop or rise that keeps the trailer level, and match the ball to the coupler. The ball mount guide covers both in two minutes.
Canadian winters eat hitch hardware. Salt and brine get into the receiver and the trailer plug, so a smear of grease on the pin, a cap on the receiver and a rinse under the bumper in spring keep a CURT hitch looking new for years. The rust and salt care guide has the full routine.
Mercedes ML320 hitch questions
Which CURT hitch fits my Mercedes ML320?
It depends on the year. CURT 13342 is the newest, for 2007 through 2008, and the table above matches every other year to its part. Open your year page and the exact hitch, price and wiring are on it.
Can I put a bike rack on a ML320 with this hitch?
Yes. The 2-inch receiver takes any 2-inch rack, and a loaded rack counts against the hitch's tongue weight (350 lb on CURT 13342), so a four-bike platform rack with bikes on it is well inside the limit.
Can I install the hitch myself?
CURT rates CURT 13342 advanced, about 60 minutes, so expect some trim or drilling work. The main body tucks behind the bumper so only the receiver shows. The install video above is the real job, uncut.
How much can a ML320 tow with a CURT hitch?
The hitch is rated from 3,500 lb to 3,500 lb depending on the part, but the ML320's own tow rating in the owner's manual is the ceiling. The lower of the two numbers is your limit, every time.
