  • Trailer Hitch Size on a 2002 Chevy Silverado
    If you have the factory hitch installed on your vehicle, then it is the 2 inch by 2 inch receiver hitch. If it is an aftermarket hitch on your vehicle then it is most likely a 2 inch receiver hitch. You will need to measure the inside width of the opening on the hitch where the receiver slides in. The measurement should be apparent when you use a ruler or tape measure. Below, links are posted to our 1-1/4 and 2 inch hitch pins and instructions for measuring your hitch.

  • Weight Capacity of Hitch Lock part # e99039
    Our hitch locks have the same capacity as a standard hitch pin. If you are worried about strength you could go with a stainless steel model like part # e98882, but since your hitch capacity is 6,000 pounds, part # e99039 would be fine. It takes quite a bit of force to shear a 5/8 pin. Usually the ball will shear off or the ball mount bend before anything else fails. I have not heard of anyone breaking any of hitch pins or hitch locks.

  • Trailer Hitch with Best Ground Clearance for 2008 Honda Element EX AWD
    All of the trailer hitches available for your 2008 Honda EX are going to have pretty similar ground clearance measurements but your best option will be with the Draw-Tite Class III # 75659. The 2 inch receiver on this hitch will pretty much sit right up against the bottom of the rear bumper on your Element (see attached image). This Class III hitch will use existing holes in the vehicle's frame for a no-drill installation and it has a 3,500 pound towing weight capacity and a 350 pound...

The highest capacity hitch is always the way to go when possible, for safety and versatility for future needs.

  • Can a High/Low Adapter be Used with a Hitch Extender for Flat Towing
    I do have a solution for you, but using an extender with a high-low adapter would be using 2 adapters and is not advisable. Hitch extenders reduce the weight rating of your hitch by 50% and will also cause more movement not to mention the torque that will be on both adapters when you are making a turn. Instead what you can do is swap out your current hitch mount tow bar, like the Blue Ox Alpha # BX7380 for a coupler mount tow bar like the Blue Ox Acclaim # BX4330. This allows you to...

    The Reese Steadi-Flex # RP66558 and the Equal-i-zer # EQ37060ET systems are both very good and will work well with your 2011 Ford F-150 and your 17SD Casita trailer. The major differences are in the tilting design of the head, the trunnion bars, and the friction points. The Equal-i-zer system uses the traditional washer stacking design for the head angle, where the Reese system uses a serrated washer design so no additional washers or stacking is needed.
