How to Torque Suspension and Equalizer Bolts when Changing Shackles on a Horse Trailer  

I have attached for you below some common torque values needed for a trailer suspension system but a lot of these will vary by bolt size and other factors. U-Bolts: Varies by Size - 1/2" bolts: 45 ft/lbs - 70 ft/lbs, 9/16" bolts: 65…

Yes, you'd just need to reach out to a qualified welder and have them weld on spring seats like part #TRSS300 to the top side of the Trailer Axle Beam with Easy Grease Spindles #e45GR. It's super common to do for people who have an underslung…

The torque requirements for leaf spring u-bolts depend on the diameter of the u-bolts that are being used. If the gross weight of your tandem axle trailer is 7,000 lbs, then you likely have two 3,500 lb axles. Typically 1/2 inch diameter u-bolts are…

The Demco Channel Tongue Trailer Coupler - Zinc - 2-5/16" Ball - 3" Channel - Bolt On - 18K #DM14040-81 has an integrated 5/16 inch pin hole with a 3 inch span for that lockable feature. I recommend using the Trailer Coupler Lock #e98888…

Suspension bolts are not designed to be torqued down tightly as this prevents the suspension from being able to move like it needs to be able to do. So the included solution with the kit part #AP233 is the lock nuts of the kit. The nuts have nylock…

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

In order to determine the torque rating for the lug nuts on your trailer you will need to know check out the chart I attached that shows all of the torque specs for all the trailer lugs available based on stud size, wheel material and wheel size.

Equalizer bolts, like the TruRyde Wet Equalizer Bolt, #TRFA71063, should be torqued to yield. Equalizer bolts are not given a specific torque rating because they should allow some movement of the equalizer. If they are torqued down too tight, the…

The suspension in general on your trailer looks very worn. I would replace as much as I could on it to get it back to good working order. The problem with the equalizer cocked to one side like that can happen sometimes. It usually fixes itself when a…

There is no specific torque rating for shackle bolts. Basically for the middle bolt there should be enough free play in the shackles to allow them to move. Tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs…

Front and rear springs hangers should be equally spaced around the center hanger and spring equalizer. It may be that your trailer was modified (if not originally built) with a different height center hanger and that might be how the spacing became…

Since suspension components use lock nuts on the ends of the shackle bolts and the bolts need to be able to allow movement you actually don't want to torque down the bolts at all. You want to snug them up so that there's no lateral play but…
