Video Transcript for In-Depth Review of the U-Bolt Kit for Mounting 8,000-lb, Round Trailer Axles

Speaker 1: Today, we're taking a look at U bolt kit for mounting 8000 pound round trailer axles. This kit attaches a trailer axle to the loose springs. It includes four eight inch long U bolts. That measurement's taken from the bottom of the U portion here out to the end of the threads. Comes with two U bolt plates for 1 and 3/4 inch, or 2 inch springs, and it comes with eight 9/16th inch by 18 hex nuts.Now, spring seats, they're required for mounting the axle to the loose springs. Ours sold separately.

If you need spring seats, you can check some options out at etrailer.com. This kit is designed for a typical 8000 pound axle that has a diameter of 3 and 1/2 inches. We're looking at nice, durable steel construction on this kit. And again, it fits springs that have a width of 1 and 3/4 inches and 2 inches. That's going to do it for today's look at the U bolt kit for mounting 8000 pound round trailer axles..

  • Hanger, U-Bolt, and Slipper Spring Kit for 8k Trailer Axles
    If you use the Dexter Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs # HAP-105-205-01 that you referenced you'd end up with a height of 4-7/8 inches between the axle center and the frame of the trailer and 8 inches between the tires for most tire sizes. How that relates to your fender to tire clearance really depends on the location you install the fenders. For an 8k slipper spring that is 2 inches wide we have the etrailer # e37SR that would work really well. The hanger kit part...

  • Can A Roadmaster Comfort Ride Suspension Be Installed A Trailer That Rides Slightly Nose High
    Yes, you can still install the Roadmaster Comfort Ride Leaf Spring Suspension Kit even though the trailer rides slightly nose high when coupled to the tow vehicle. When installing one of these kits you'll most likely need to get longer U-bolts since there typically aren't enough threads to accommodate the additional mounting brackets. To determine the right kit and U-bolts you'll need to know the capacity and diameter of your axles and how many axles your trailer has. 3.5k 2-3/8" Tandem...

  • 12 Inch Long Equalizer For 2 Inch Slipper Springs & 8,000 lb U-Bolts For Tandem Axle Trailer
    There isn't a complete kit, but I can go ahead and list out everything you need for a 12 inch long equalizer for 2 inch slipper springs, along with the mounting hardware and U-bolts for your 8,000 lb axles. Here is what you need for your tandem axle trailer: - 2 of the Equalizer for 2" Wide Slipper Springs # TREQ4541 - 8 of the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079 - 2 of the Equalizer Bolt with Cotter Pin and Castle Nut - 7/8" Diameter # 166078 - 2...

  • Torque Spec for U-Bolt Kit of 8k Trailer Axle
    An 8k axle u-bolt kit has 9/16 inch diameter u-bolts so the correct torque spec would be 65-95 ft lbs.

  • How to Determine Correct Replacement Slipper Springs for Triple Axle Trailer With 8,000 lb Axles
    I can help you determine exactly what you need to replace the suspension in your triple axle trailer, although we don't have any type of database which has each part for each year, make and model of trailer that would tell us exactly what you have on your trailer, which means you'll need to do a bit of pretty simple measuring. Since you have a triple axle trailer, with three 8,000 lb axles you will need slipper springs for that axle capacity, for which we have two of that capacity. To...

  • Parts Needed For Reducing 7,000LB Leaf Springs On a 2021 Keystone Carbon From Flattening
    I do have a recommendation for you as switching out all your leaf springs on your 2021 Keystone Carbon 358 is a big undertaking. The SumoSprings Trailer Helper Springs # SS26MV are designed to work on 5,000lb to 8,000lb trailer axles and each set provides 900lbs or capacity at 50% compression. These springs are also progressive so they will help to absorb road shock while also providing support to your leaf springs giving a smoother ride inside your trailer to reduce the odds of damage...

  • Spacing Between Hangers With Slipper Springs for 8,000 lb Axles and Hanger Kit
    I checked for you and when installing the 7-Leaf Slipper Spring w/ Hook End for 8,000-lb Trailer Axles # e37SR with the Tandem-Axle Trailer Hanger Kit for 2" Slipper Springs - 12" Long Equalizers # APT6SE the distance between the front and center hangers will be 28-1/2", the distance between the center and rear hangers will be 29-1/2", the distance between the U-bolts will be 33" and distance between the center of the axle and trailer frame will be 4-1/2". I made a diagram for you which...

  • Trouble Shooting Furrion Camera That Is Flickering
    It sounds like your running light pin is not providing enough power for the three cameras. I would recommend using The 7-Way Vehicle Power Adapter w/ Power Switch for Furrion RV Observation Camera # FR87PR. This harness will connect the trailer wiring from your tow vehicle's 7-way trailer connector. It will provide your camera extra power. If this doesn't help I would reach out to where you purchased the cameras from. It could be an internal problem. I attached a review video link below.

  • Are 8k Trailer Leaf Springs Compatible with Over and Underslung Axles
    The 7 leaf spring part # DX74XR that you referenced can be used in under or over slung axle configurations. Leaf springs aren't made for either style and can easily fit both. It would be just a matter of going with correct u-bolt kit for the axle capacity like the # APUBR-35 which was designed for 8k axles that are 3-1/2 inches in diameter.

  • Raising the Height of a Trailer that has a 3-1/2 Inch Diameter Round Axle
    There are no over/under conversion kits for a 3-1/2 inch diameter axle but I can tell you the parts you will need to make one. You will need spring seats for 3-1/2 inch diameter axles, # TRSS350 and a new u-bolt kit # APUBR-35. The new springs will have to be welded onto the axle.

  • Recommended Roadmaster Comfort Ride System For A 2024 Forest River Riverstone Legacy 421FK
    Hey Jeff, To find the correct Roadmaster Comfort Ride kit for your 2024 Riverstone Legacy 421FK you'll need to check the axles for their weight capacity. Once we know the axle capacity we can pick the corresponding kit: 5k # RM-2460-2560-3 7k # RM-2460-2570-3 8k # RM-2470-2580-3 The slipper spring box would need to be aligned to the spring centers on the axle and center of the trailer frame when being installed so there isn't a separate alignment job that you'll need to complete afterwards....

  • What Are The Longest U-Bolts Available For A 3" Axle?
    Hello Tom, thanks for getting in touch. The longest U-bolt for a 3" axle we offer are the MORryde U-Bolts for 5,200-lb to 7,000-lb Round Trailer Axles # MR66ZR. These are 3" wide and 7-3/4" long. There is nothing exactly 8" long, so this will be our closest option.

  • Hanger Kit, U-Bolt Kit and Spring Seats for Tandem Axle Trailer with 3-1/2 Inch Diameter Round Axles
    A 3-1/2 inch diameter round axle is usually rated at 8,000 pounds but could also be a 3,500 pound axle though this is rare. You can get a more accurate determination of the capacity by getting the inner and outer bearing numbers stamped into the sides of the bearings. For a hanger kit # APT3 will keep the distance from the deck to the axles at a minimum and still have room for suspension travel. You will also need a u-bolt kit, # APUBR-35, for one axle. And you will likely need new spring...
