Video Transcript for Dexter Axle Trailer Suspension - Leaf Spring Suspension - K71-359-00 Review

Speaker 1: Today, we're gonna be taking a look at the Dexter heavy duty suspension kit for tandem axle trailers. This works with 1 3/4" wide double eyes springs. The part number is K71-359-00. Now this suspension kit includes equalizers and the hardware for attaching four leaf springs to the hangers of your trailer's frame. Now keep in mind that those hangers are not included. But you can find a lot of options here at etrailer.com.

This works with 33" axle spacing. It has built in grease inaudible 00:00:30 for easy lubrication and the heavy duty shackle straps ensure great strength. This suspension kit, again, it does work with 1 3/4" double wide double eyes springs and the equalizer is going to work to transfer the load and impacts from one axle to the other by permitting that movement between the axles. The springs are going to attach the ends of the equalizer with the included hardware. The wet bolt secure equalizers and the spring to the hangers of your trailers and the grease inaudible 00:01:04, again, allow for fast and easy lubrication to keep moving parts functioning at their best.If you take a look here, you can see that hole in the bolt.

That's gonna be where the grease comes out, lubricating that bolt, making it move nice and easily. Now the heavy duty shackle link assemblies with bolts secure this frame to the equalizer. They have 1/2" thick links and they're thicker than your standard straps. So they're gonna have greater durability. The bushings fit into the eye springs to help maintain a well functioning system and ensure proper sizing for suspension bolts.

Bronze construction also resists corrosion. So that's one less thing to worry about there. This kit includes two equalizers, 14 flange nuts, one for each bolt, two shoulder bolts, the silver one here that goes through the top of the equalizer and then four shoulder bolts that are just separate on their own that are going to go through the end of the leaf springs. It has eight 9/16" by 1 3/4" bushings, as you see here. It has four shackle links and four shackle link assemblies, which are these here.As far as the specs on this, this is going to work, again, with tandem axle trailers that have that 1 3/4" double eyes springs.

The axle needs to be 33" and the equalizer dimensions are going to be 2" tall. That's 5 3/4" long from center to center. So if you take a look here, if we measure from the center of this equalizer to the center of the other, that's going to give you that 5 3/4" measurement. The shackle strap length is going to be 2 1/4". So again, going from center on center, that gives you 2 1/4. Dexter does offer a five year limited warranty with this kit and that's gonna do it for our look at the Dexter heavy duty suspension kit for tandem axle trailers, part number K71-359-00.

The only issue I had, which was to be expected, was when you install the brass/bronze ? bushing insert/sleeve, even using a snap on bushing installer tool, it mushrooms and deforms a bit. No biggie, run a file or drill bit thru and teat fit the bolts. Pre lube/slather in marine grease and good to go, as the grease fittings may be hard to reach and you find yourself not lubing it as often as you shoud. Eliminated all popping when turning in a parking lot from the trailer. I'm sure these will eventually wear and develope some slop but the other alternative of paper thin nylon bushings doesnt work with me. Price was right.And was best price after my research. 718435

This kit was installed on my Ez Loader custom boat trailer that is about 14 years old. The trailer was making a lot of noise mostly noticeable in the campground driving slow and turning sharp. After installing this kit the boat trailer made almost no noise making the same maneuvers. This kit was probably overkill for my boat trailer, but it deserves a 5 star review. 694803

Although I have not installed the trailer suspension part yet, they look stout and well made! I am looking forward to pulling my 1985 Hudson with the new upgrades! I really like the emails that's I receive periodically from etrailer too, informative and timely! I suggest the you subscribe. And lastly, I ordered the product on Tuesday and had it in hand Friday! Texas to Pennsylvania. 549637

The shackles are twice as thick as the factory ones we replaced. With the Zerk fittings will should be much stronger and more secure. 680505

- K71-359-00

Without hesitation I would reorder from etrailer.com again. The parts were perfect and the information pertaining to leaf springs was right on. 673105

Thanks again for a great product as you always do. 483238

- K71-359-00

Installed easily. Air tools are handy for this. Trailer is much quieter and being able to lube the bushings is a good idea. Hopefully will be less wear but can't know w/o taking it apart. So far I'm happy with this choice. 688498

- K71-359-00

They were on backorder but arrived quicker then thought, always great service from etrailer. 575328

good. 649778

- K71-359-00

Shackle kit fit well and seems very heavy duty. Packaging was not good. All the parts were loose inside a cardboard box that was poorly taped closed. Many of the nuts had fallen out of the box. This slowed the repair for my customer and myself. 638490

- K71-359-00

After discovering that I needed to replace the deformed leaf springs on our 2013 tandem axle 24' travel trailer due to a frightful traffic incident in June, I decided to upgrade to a "wet bolt" suspension system since it would entail very little extra work during the repair effort. I settled on this kit due to the fact that there aren't any non-metallic components to degrade and we don't travel thousands of miles every year. I've already completed the installation, and was really impressed with the robustness and precision fit of every component. The grease channels were cleanly drilled in each bolt, and all of the threaded grease fittings worked perfectly. I have no doubt that the trailer will be more stable and quieter during our future travels. 581388

Great fit, grease fittings - much better than oem 614745

Fit perfect for my dexter 3500 axles. No more squeaking or clunking!!! 655323

Product work beautiful It took 2 hours from start to finish to install the whole kit The staff at the e trailer was very helpful 678501

- K71-359-00

Excellent product. I did strip a nut trying to draw one of the pins in instead of pounding it in like the instructions said. Otherwise everything went together without a hitch. Used a 5/8 bolt to remove the nylon bushings. Threaded it into the bushing a little and then pounded them out I used a half inch carriage bolt with nuts and washers to install the bushings instead of pounding them in. Worked pretty slick. Looking forward to many trouble free miles 651475

K71 359 00 Wet bolt heavy duty suspension kit. The kit looked good so I installed the first side. When I tried to grease it one of the bolts won't take grease, after changing the zerk it still wouldn't so I took it apart to find the bolt had not been drilled deep enough so the grease was dead ending in the bolt. So if you buy this kit, pump grease thru all of the bolts before you install 654649

great upgrade 597862

- K71-359-00

Much beefier shackle design with wet bolts and metal bushings to replace the cheap thin plastic that LCI provides with their shackles and pivot. Very pleased with the outcome. 691145

- K71-359-00

Fit great can feel the difference in how smooth the trailer pulls. Much tighter, quieter, and smoother. Free shipping and my parts showed up in 1 day. 737028

- K71-359-00

Product seems to be well made. I could not use the bushings on the older spring set I have on my utility trailer. Nice feature to be able to grease these pivot points. The shackles (hangers) are definitely heavy duty and should last a long time. Received the product in a timely manner and am very satisfied with the company and product. Gave a 4 rating because time in use will tell how the product preforms. Would have been nice to be able to select a different design on the equalizer bar for different applications. 732262

- K71-359-00

It took some time to install. Here are a few of the 'tricks'. Use PB blaster on old hardware. Use block of wood to pound in the brass bushings. When they will not fully insert, use one of the old bolts to suck it. Remove the ridges on the old bolt to prevent damaging the bushing. Tighten the nut, remove, add washer, tighten nut again, remove, add 2nd washer and tighten nut again.... To fully install new bolt, use a washer to suck in the bolt. Amateur like me can do it in about 5 hours from start to finish. The trailer was lifted with wheels barely off the ground. Removed the wheels and creatively used the jack to lift/lower axle(s) to get the hardware removed/installed. 729179

- K71-359-00

Everything went together perfectly and had no problems. 728153

- K71-359-00

The parts are just what I needed, haven't installed yet but etrailer is a great site to do business with. The kit came in short a few parts but a call to etrailer and the missing parts were shipped out and delivered in very quick time. 725626
