When using a weight distribution system with air bag helper springs you will first couple the trailer to your 2011 Ford F-150. Do not engage the spring bars yet. Then add air to the air bags. Last, engage the spring bars. After checking the set up you may need to add or remove air from the air bags.

You'd be better off hitching the trailer or loading the truck bed or the vehicle's cargo area before adding or removing air from the system. The trailer tongue weight or cargo loaded in/on the vehicle will cause the rear end of the vehicle to…

If the owner's manual for your 2001 Ford Explorer Sport Trac states that you have a 500 lb tongue weight rating then you will easily be able to tow a 456 lb bike, like the 2003 V Strom 1000, on a motorcycle trailer. If you are talking about a…

I do have a solution for you, but unfortunately we do not have any Multipurpose Ball Mounts like the Curt #D210 that feature a 4" drop. Instead what you can use is a Gen-Y adjustable ball mount like part #325-GH-523 which has a 5" drop…

Answer 6

The Curt #D210 is a dual hitch option that has a tongue weight rating of 750 lbs. This is going to be the best option we have. Basically this has a ball mount platform on bottom and then a hitch tube mounted above it.

Hey Doug! The Firestone Ride-Rite Air Helper Springs #F35FV are the right kit for your 2026 Ford F-350 FX4 dually. However, you will need to measure to be sure it fits. The distance from the top of your rear axle to the top of the jounce bump stop…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…

Answer 12

The difference between an load range C and load range D tire in the same size is the capacity and psi rating. The two tires will still have the same dimensions and fit on the same wheel. The D rated tire has a higher capacity. For a ST175/80D13 like…
