The Curt hitch part # C11499 that fits your 2011 Infiniti G25 does have the capacity to tow a trailer that weighs up to 2,000 lbs so what you mentioned would be fine to tow the trailer you mentioned. You should also verify the towing capacity of your vehicle in the owners manual. You'd also need trailer wiring like the part # C56033, a ball mount # C45521, a hitch ball like part # A-82 for a 2 inch hitch ball or # A-80 for a 1-7/8 inch hitch balls, and a hitch pin part # F-4. view full answer...
We've received a few reviews on the Curt hitch part # C11499 where it was noted that the included bolts were a little short so going with 35 mm bolts sourced locally instead was needed. The bolt size this comes with is 1/2-13 x 1 3/4. view full answer...
