A quick and easy way to judge what size drop you need is to measure from the ground up to the inside top of your 2" receiver tube. Use the guidelines below to help you pick the right Rapid Hitch for you. Be aware that the tongue heights of your trailers and the suspension on your truck also play a part in choosing the right hitch, but in most cases, these measurements will give you what you need. If you are unsure, please take your truck to your local dealer for advice.

If the measurement is 20" or less then a 4" drop is for you.
If the measurement is between 20" and 24" you need the 6" drop.
If the measurement is between 24" and 28" check out the 8" drop.
If you measure more than 28" you will need the 10" drop (Can work 24" and more).
