SYSTEM WEIGHT RATING vs. COMPONENT WEIGHT RATING
A towing system includes each vehicle and component involved in towing. Each item in your towing system has a capacity
or weight rating. You trailer has a Gross Vehicle Weight Rating, or GVWR. Your truck has a tow capacity, payload
capacity, and possibly more. In addition, your fth wheel hitch has a weight rating. This weight rating must be at, or
above, the GVWR of your trailer for you to tow safely. In addition, if your truck can tow larger loads (has a larger capacity)
than the rating of your hitch, your system is only safe to tow loads at the lower rating, that of the hitch.
Your mounting kit also has a weight rating, just like your fth wheel hitch. Many times, these rating are designed to match.
But, this is not always the case. Your mounting kit may be higher rated than your fth wheel hitch, but it also could be
lower depending on the components involved. The lowest rating of any one component in the system becomes the
rating of the entire system. If your mounting kit is rated to 18,000 lbs., and your hitch is rated at 24,000 lbs., the weight
rating of the entire system will not be above 18,000 lbs. Other components in the system could lower the actual system
rating further.
It is the end users responsibility to ensure a safe towing experience. To this end, it is your responsibility to ensure that
the truck, trailer, hitching components, and all other items involved are rated or have a capacity sufcient for the loads
involved.
LUBRICATION
DO NOT OPERATE HITCH UNTIL YOU READ THIS SECTION!
KING PIN ADAPTER BALL & COUPLER TUBE
The King Pin Adapter Ball and Remote Latch System must be
lubricated before each trip or as needed. PullRite recommends
using a dry graphite spray to prevent the attraction of dust and
debris. A light wet lubricant such as WD-40 can also be used,
but the two types of lubricants should not be used together.
Be sure the Coupler Tube is free of any obstructions prior to
lubrication and before each use. Spray both the Tube and
Funnel areas to aid in hitching up.
When lubricating the Remote Latch System using a dry graphite
spray, place the latch system in both closed and open positions
to cover the spring and pin effectively. If using a wet lube, pull
the Release Handle repeatedly between the open and closed
positions, so the lubricant is evenly spread among the moving
parts.
Be sure the King Pin Adapter Ball is clean and free from rust. A
light coating of lubricant should be used before each trip or as
needed.
Inspect all mounting brackets and hitch hardware to verify that it is securely fastened. Inspect all mounting bolts for
tightness and general condition.
When storing your SuperLite hitch, you should be sure that the coupler and hitch parts are lubricated with WD-40,
dry lube, or a combination of both—wet lube for other wear areas such as the contact area between the Hitch Base
and the Base Rails where the paint may rub off—to retard the formation of rust. Cover the entire assembly to prevent
accumulation of dirt, grime, or rust.
