Recommended Weight Distribution Shank for Triple Axle Trailer Towed by 2013 Suburban

Question:

Im interested in purchasing a trunnion weight distribution hitch. I currently use a 6inch on a tri-axle trailer to get it leveled. My 13 Suburban squats badly. Should I purchase a WDH shank with extra ? Im getting worried about road clearance. What should I do?

The first step is to ensure that the unloaded rear end of your Suburban is at factory ride height. If the rear suspension components are worn or damaged, have them replaced/repaired.

The next step would be to determine the difference in the receiver height of vehicle and the coupler height of the trailer, when parked on level ground. Measure the distance from the inside top of the receiver tube to the ground, then measure the distance from the underside of the trailer coupler to the ground. The difference between these two measurements is the rise/drop of the weight distribution shank you'll need. To account for the initial squat, you'll need to set the ball about 1 to 1-1/2 inches high (above level).

If you needed a 6 inch rise ball mount to get the trailer level, you'll need a weight distribution shank that gives you at least 7-1/2 inches of rise. I'd recommend the Curt # C17121 shank, which would give you plenty of flexibility.

If you'd care to reply with the fully loaded and ready to tow tongue weight of your trailer, and the weight of any cargo carried behind the rear axle of your Suburban, plus a description of what type of trailer you have (boat trailer, cargo trailer, etc), I'd be happy to make a weight distribution system recommendation for you.
