Class IV Hitch Receivers:
- Are for heavy duty towing.
- They typically have a towing capacity of 10,000 lbs. of gross trailer weight and the tongue weight is usually 10% of towing capacity, so 1000 lbs. in this case.
- A prime candidate for towing large boat trailers, RVs, livestock trailers and other similarly large trailers.
- Can be used for hitch-mounted cargo carriers and bike racks.
- They have an opening of 2″ x 2″.
- Available for full-size pickup trucks and SUVs.
- Compatible with a weight distribution hitch, which increases the overall capacity for towing. The gross trailer weight capacity increases to 14,000 lbs. and the tongue weight capacity to 1,400 lbs.
- Available from all major hitch manufacturers like Curt, Hidden Hitch and Draw-Tite.
These setups are only as strong as their weakest link. Never exceed the lowest weight capacity of any towing component! The vehicle, hitch, drawbar, ball and trailer all have weight capacities and specifications that are important to note and adhere to.
Torque when using your hitch for bikes is also important to consider – as every foot out from the hitch you extend, you cut your weight capacity in half! You need to calculate the weight of the bike rack as well as the bikes themselves and be sure to keep the heaviest ones as close to the back of the vehicle as possible.
