Eaz-Lift's Elite Weight Distribution Hitch with Height Adjustable Forged Shank is designed to provide trailers with a smoother ride than that found in other hitches. It also saves time with pre-installed components— the U-bolts and chain package are pre-installed on the spring bars. Universal round spring bars are interchangeable, used conveniently on either side of the hitch. When the spring bars are pushed into the ball mount, the locking device has a positive latching action (clicks and locks-in) for operation. This hitch has a maximum tongue weight of 1,200 lb. and a maximum gross weight rating of 12,000 lb. It comes with all necessary parts, including: hook-up brackets, spring bars, chains, ball mount, shank and hitch pin, clip and bolt package for adjustable hitches. Camco makes quality products for RVing, boating, camping, towing, tailgating, and grilling that help you take your passion for the outdoors to the next level.
