Yes, Lippert and Dexter 7k axles use exact same bearings. The only issue you might run into is a difference in grease seal size required. There are two sizes of grease seals that fit 7k axles and there isn't a rhyme or reason as to which you may have/need. So if the spindle diameter if 2.2250 inch where the seal rides the correct seal you would need is the part # GS-2250DL or if it's 2.125 inch you'd instead need the part # GS-2125DL.

There is no specific torque rating when reinstalling the castle nut after packing the bearings. You want to run the nut down until there is no side to side play in the hub, and then back it off to the next notch in the castle nut so the retainer can…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…

If you are installing just the Firestone Ride-Rite kit, #F2400, and not also adding an on-board air compressor such as #F2158, then I would estimate that it should take about 2 hours to install the kit. That is for someone with some mechanical…

The number you provided, "7753400" is a patent number which corelates to the Equalizer for E-Z Flex Suspension part #013-144-03. This is for a single equalizer but if you need the entire kit it's the Dexter E-Z Flex Suspension Kit part…

For your enclosed trailer application I have several suggestions for adding interior lighting that you can control directly via a switch. Since your current 4-pole trailer wiring does NOT include a 12V auxiliary power feed that could power inside…

The only way you could power interior dome lights on a trailer without it being connected to a tow vehicle would be to power the lights with a battery like a breakaway battery. How you choose to wire up the batteries will in the end be up to you, but…

Answer 12

If your current springs have 5 leaves then going to a 7 leaf spring will increase the height of the trailer a little and make the trailer more susceptible to sway. Regarding capacity if you go with springs rated higher than what is required it will…
