Hey Kevin I do appreciate you reaching out but I am sorry to say we do not offer an axle that matches your specifications. We have only a few square tube marine axles and they are all much shorter than what you are looking for. We could provide hubs for said axle, but for the axle itself you will need to look elsewhere.

Thanks for getting back to me! Do you have a non tubed axle that would work for my application?

@KevinM We do have the Timbren Axle-Less Trailer Suspension # A35RS545 which is 3,500 lb rated and has 5 on 4-1/2" idler hubs. They bolt directly to the frame. Some applications requires adding a 2"x2" steel cross tube for additional support. As far as our tube axles we have mostly round tube axles. The closest to what you need would be a 72" hub face like part # 20545I-EZ-72-10. This is rated for 2,200 lbs. Any idea how much the boat and trailer weigh?

While it's not recommend, bearing greases with the same base like the LubriMatic Marine Trailer Wheel Bearing Grease #L54FR and your Lucas marine bearing grease can be mixed as long as long as they have the same base.

I can help you with greasing up your EZ Lube Axle. First thing I would check would be that the grease is not coming out of the back of the axle through the seal. If this is the case you will need to replace the seal. Our tubes like #L11390 have 14…

You will need either the Dexter Trailer Idler Hub Assembly for 2,200-lb Axles #8-259-50UC1 for 8-12" wheels or the Assembly #8-258-50UC1 for 13-15" wheels. Both these hubs use the 1-1//16" Bearing #L44649 for inner and outer bearings.…

Answer 6

If you are using 9/16 inch shackle bolts which are the most common you will want 65 to 95 foot pounds of torque. If you are using 1/2 inch then go for 45 to 70 foot pounds. And for 5/8 inch bolts use 100 to 120 foot pounds. All of these components…

You have a really interesting suspension setup on your trailer. I don't know what the width of the channel is that your springs attach to but to go to a double leaf will require using a hanger kit like the part #APS4 that you referenced. If you…

Hey John, thanks for reaching out. The recommended placement of an axle on a single axle trailer will be determined by tongue weight. There are two formulas to determine axle placement. One formula is for trailers with a tongue weight (TW) greater…

The closest leaf spring set we have available to the 22-1/4 inch length you mentioned is the 3-Leaf Double-Eye Spring #SP-113275. This double-eye leaf spring features a length of 23-1/2 inches from the center of the spring eye to the center of the…

We do have a couple of bolt-on spring hangers #CE14017G and #CE14016G but they are designed for slipper springs and not double-eye springs like #e77SR. Its not likely that professional welder would charge that much. You might be able to find one…

Answer 11

You will want to weld the hangers of the Trailer Hanger Kit #AP202-H238. The holes you see are not designed to have bolts run through them. If you did run bolts they would most likely interfere with the spring and how it would sit on the hanger. I…
