New Brake Assemblies, Hub/Drums, Brake Lines, and Bearing Buddy for Trailer with 3,500 lb Axle
Question:
I have recently been convinced to replace the leaf springs on my trailer in addition to the breaks, drums and coupler. My trailer has a 2inch wide x 3inch tall rectangular axel of unknown weight capacity. The C-hook slipper springs have 5 leaves and are rusted and played out - under load they barely catch the rear spring bolt. I am looking at your part #SP-264275. While it only has 4 leaves, my boat weighs in at 2250# empty and I suspect with a full load it wouldnt top 3200. This spring is rated to handle that load, but I wonder if I should keep with a 5 leaf spring instead. If you think SP-264275 would be adequate for my trailer, which plates, u-bolts, and spring bolts would I need to finish the installation. Sorry no pictures, major winter storm going on.

For as trashed as those brake assemblies are I am impressed with how spotless that spindle is! Based on the bearing numbers you mentioned you have a #84 spindle and the hub part # AKHD-545-35-G-K is correct. Since this its galvanized it's a really great option as it will fight corrosion.
The flexible brake line kits like the part # 18SI-BLKIT is what I would go with. They are just as durable as anything else and a lot easier to install. The brake assemblies # AKFBBRK-35R-D and # AKFBBRK-35L-D are correct and great choice as well. For a Bearing Buddy you'd want the part # BB1980A-SS and for a grease gun and marine grease cartridges we have the part # 30-800 and # L54FR and you'd be set!

First of all, let me thank you for the help with choosing brakes and drums for my old boat trailer. I ordered all the parts this morning and went ahead and ordered a new brake actuator as well part # 8605001. My old coupler is an Atwood and was welded onto the trailer tongue. I thought I could just cut it off, but on closer examination the welds are pretty extensive running along 5 of the bottom, up the back side and into the top for a couple of inches. The bead of the weld is huge- I think they were taking up the space between the tongue 2.5 and in channel of the coupler 3. Now I could spend most of the day and a dozen sawsall blades and cut it off I already started for about 5 minutes and didnt get far, or perhaps I could just cut the tongue right behind the coupler? Drill holes for the new coupler and call it good? That would be the easiest, but the question is, would the tongue now be too short by 5.25 for safely turning corners and such? Now this is an extension tongue so an option would be to pull the pins, extend the tongue, mount the coupler and re-drill holes for the pins there-by regaining the 5.25. Only problem there is the tongue is thoroughly corroded to the tunnel and will take some work to free, which I will probably want to do anyway. Option A: cut and replace. Option B: cut the tongue and mount as is. Option C: cut the tongue, extend and re-drill the pin holes.
