Dutton-Lainson Square Swivel Jack Review Video

While a lot of wheels have cross compatibility with 1/2"-20 or 9/16"-18 wheel bolts, the Karrier ST235/80R16 Radial Trailer Tire with 16" Aluminum Wheel #KE39JR states that it only works with the 1/2"-20 wheel studs. We do have…

According to my contact at Dexter Axle, their Trailer Hub and Drum Assembly #42866UC3-EZ fits a wheel with a 4-3/4-inch pilot hole and a 8-on-6-1/2 bolt pattern. Each hub carries a 3500-lb rating.

Pilot diameter on a wheel like our dually trailer wheel part #AM20783 that you referenced is basically the diameter of the center hole of the wheel. This wheel has a pilot diameter of 4.75 inches. I attached a picture that shows this dimension as…

Any given tire size will fit a range of wheel widths. For a 175/80-13 trailer tire it will fit a 13 inch wheel that is 4-1/2, 5, or 5-1/2 inches wide. Wheel #AM20222DX is a 13 x 4-1/2 inch wheel so a 175/80-13 tire will fit on it. This wheel has a 4…

Easiest way would be to use a strap like a bungee part #EM06701to wrap around the handle and jack body to hold the handle to the jack.

The 7/16"-20 Flange Nut #LC122103 will fit the Wet Shoulder Bolt #MR52HR.

I have included a dimensional drawing of the Dutton-Lainson Round Swivel Jack #DL22335 that shows the overall extended height of the jack at 40-5/8" tall. This measurement is from the bottom of the wheel to the top of the jack when extended.

For saltwater boat trailer use it is recommended to go with either a galvanized steel rim or a aluminum wheel. For a galvanized option I recommend the Americana Steel Spoke Trailer Wheel part #AM20354. Both these rims have excellent corrosion…

The Dutton-Lainson Square Swivel Jack #DL22340 has a mounting plate designed to fit trailer frames with a height of 3" - 5". I have attached a dimensional drawing below with all of the bolt spacing for your reference.

If the solenoid is getting a full 12 volts and is grounding properly it should be shutting all the way. Since you said it is clicking that makes it sound like it's getting power. You could try improving the ground circuit but most likely…

We aren't going to have a jack that's going to bolt right up to the same mounting bracket your Shelby mounted to so your best option will be to cut off the old mounting bracket and weld on a new one like with what you could do with the Fulton…

Normally the SAE number isn't a reliable way to pick out replacement lenses, but we know that the #A32RB is the correct replacement for a lens marked SAE-A-P2-DOT-02 like what you have. For an all new assembly you'd want the part #MC32RB.
