Video Transcript for Dexter Axle Trailer Suspension - Leaf Spring Suspension - K71-449-00 Review

Speaker 1: Today we're taking a look at the Dexter Heavy Duty Suspension Kit for Tandem Axle Trailers.This suspension kit lets you attach four leaf springs to your trailer frame. It works with 1-3/4" wide double-eye springs. Your hangers are sold separately. The equalizers, which are the center component here, these transfer load and impact from one axle to another by permitting movement between the axles. Your springs attach to the ends of the equalizers with the included hardware. The wet bolts, which are the bolts that have the zerk fittings on them, the wet bolts secure the equalizers and springs to the hangers on your trailer.

The grease zerks allow for fast, easy lubrication to keep all the moving parts functioning as they should, and at their best.The heavy duty shackle link assemblies with the bolts secure the springs to the equalizers. These are 1/2" thick straps or links that are thicker when compared to standard straps or links, so these offer greater durability.It does come with your bushings that fit into the spring eyes to help maintain a well-functioning system, and ensure proper sizing for suspension bolts. These are made from a durable bronze construction, which they're strong and durable, and they do a great job at resisting rust and corrosion.The kit comes with everything you see here on the table, so you get both equalizers. You get all the necessary shackle straps. You get all the necessary wet bolts with zerk fittings.

You get the two dry bolts, located here at the top of the equalizers. Then also, on the top of the equalizers, we have zerk fittings, again, to keep those moving components lubricated for a longer life. It also comes with all the necessary bushings, and all the necessary flange nuts.Now, this is designed for tandem axle trailers with 1-3/4" double-eye springs, axle spacing of 35". The equalizers, they're the same. From the center of this hole to the center of this hole, we have 7-3/4", and they measure around 2-7/8" tall.

So, if you draw a straight line from this hole to this hole, and then measure up to this hole, center on center, that's going to be 2-7/8" tall. The shackle straps are all the same. They measure 2-1/4" from the center of one hole to the center of the other hole.That's going to do it for today's look at the Dexter Heavy Duty Suspension Kit for Tandem Axle Trailers.

Fit up perfectly. Split the old nuts using a right angle grinder with a cutting wheel. Heated the spring enough to soften the plastic bushing and allow the bolt to be pounded out with a hammer. I used an 11/16 drill bit to remove rust and debris from spring end and used a c-clamp to press in the new bronze bushing. Everything else went together like the instructions said. Attached a before and after photo. 673027

Havent installed yet but this is really beefy, and I love the fact that I can grease all the joints now. These brackets are more than double the thickness of OEM. 396890


Comments

A year later and these have been on for 10 months or so. Due to a defect in my trailer mounts, I wasnt able to use the included bushings, but it still is quiter, and beefier than OEM, at about half the price of the local autoparts store.

Ran these over ice and snow on I-40 from Tucumcari to Albuquerque and didn't loose anything inside. If your shackles are rusted and can't be lubed this is the fix for you. Replaced these on a 2003 Mobile Suites fifth wheel. 727102

I waited to complete this review until after my scheduled trip this year. I purchased these suspension parts for my 15 year old 5th wheel. They arrived as promised and were the great quality we have become accustomed to with Dexter. It was the correct kit and installation was a breeze. After all these years, I appreciate the fact that the suspension can now be lubed. The rebuild made for an enjoyable 5000 mile trip. No more squeaking and creaking, moaning and groaning but enough about my wife....just kidding! The rebuild made a huge difference. I am a big fan of etrailer.com and use it at every chance. Their staff is very knowledgeable and they deliver on what they promise. Their products are top quality. Use them whenever you can! 719023

Easy to work with, good fit and pleased with quality. Only downside, and it is minor, is that the straight zerks need to be replaced with 90's. The tires do not permit access to straight zerks. Parts are holding up well. 707216

Recently broke shackle straps 600 miles from home. Lost two days finding and installing new parts. This kit is so much more robust than the stock parts it's ridiculous. Installing new parts will be easy and will make for peace of mind on the road. 706483

etrailer- I cant say thank you enough Finally, someone sells a product that is done right. Within 9 months of purchasing a brand new twin 5200 lb tandem axle trailer, i lost an axle due to light flimsy spring shackles that wore through ( no way to grease them either) .I have been towing tandem trailers for the past 30 years, always having undercarriage issues (hangers and equalizers by other companies wearing through one being cheaper and thinner than the next. These are truly Heavy Duty... I can now travel down the road feeling confident that my leaf springs and axles are strong, sturdy and over engineered. etrailer was the only one i found that sold truly Heavy Duty Hardware that is truly over engineered and realistically, under priced... Thanks again etrailer 703385

Better quality than the ones we took of f. 593621



- K71-449-00

Ah.. now I can tow with confidence knowing my axles are once again equalizing and sharing the bumps as they should be. With the grease-able fittings I also know this is continue for years to come. Feels very heavy duty, trailers well on the trips I've taken so far. Installation was very easy, though to use the brass bushings in the springs I had to drive out the nylon bushing that came in the new springs. This was easy to do with bolt of the right size and the brass bushings -- just tap tap tap and the nylons were pushed out by the brass, all guided and kept aligned with the bolt. 579806



- K71-449-00
by:

Great upgrade to your trailer suspension. The equalizers on my trailer were froze and would not move, I had to heat the bolts until the plastic bushings melted, then drove the bolts out. In doing so this left a fair amount of crud inside the spring eyes, I had access to an 11/16" hand reamer so I ran it through the spring eyes, then the bushings slid in with a nice snug fit, and in doing so I did not experience distortion inside the bushings like others have mentioned. I was disappointed to find that the equalizer center pivot bolt did not come with a new nut. The kit shows enough nuts for all the bolts but the nuts only fit the wet bolts. If the kit had included the two 9/16"-18 nuts I would have given 5 stars. 566050

I am very pleased with your product! Wow I was not expecting such quality. I made a mistake and ordered the wrong kit, Pat was able to correct my mistake and re ordered the correct kit. Your customer service agent Pat explained the procedure, and everything worked perfect. You have a new customer. 555958

The products I ordered arrived ahead of schedule and fit perfectly! The only complaint I have is the packaging. All the components (4 leaf springs, suspension kit, and u-bolts were just thrown into an over sized box, then shipped. When it arrived, the leaf springs were sticking out the sides and there were holes big enough for the smaller boxes to fall out. Fortunately, everything was there. This is the second time I have ordered product is was packed very poorly! 544844

Everything went together with no problems. Don't like the bolts with the smaller diameter (7/16) threaded section,.. difficult to determine whether the whole shaft was through the hanger all the way and the smaller nuts don't give you a good sense of security. Will have to check that none of the nuts come loose. As a note, the package from the manufacture arrived with damage to it (very fragile package for heavy parts) and was missing two shackle links, but Dexter sent replacements. 488516

I'm so disappointed that etrailer does not carry full line of Dexter ez lube axles. I live in Ohio and ordered from another online supplier. Even trailer shipped the day I placed my order. 4 days ago. I won't have axles ship from Texas for another 4 days. etrailer is on the ball !! Why don't they carry more parts ?? I'm just waiting and waiting while my business suffers without it's tool trailer..... 436387

Got the kit on time and in good condition - thanks, etrailer! Everything I needed was in the box, along with instructions. I had two minor issues with the kit (it's a Dexter Axle product, so this doesn't reflect negatively on etrailer). The bushings are thin enough that they conform to an out-of-round hole, like I had in the ends of the leaf springs (they're curled into a loop). Because of this, some of the bushings were malformed after being pushed in (I used a C-clamp, not a hammer), so I ended up having to use a round file on a few to make the studs fit. Additionally, all the bushings fit close enough to the studs that I was unable to get grease into them using the grease zerk. The only one that would take grease was the center pivot of the equalizer. Otherwise this kit is a nice, heavy-duty alternative (especially the shackles) to the worn-out pieces that I had. 421519

My kit was shipped fast. I was hoping to get the trailer back on the road in no time but it seems my springs have 9/16 x 3/4 bushings. Another order... The shackles are huge compared to the original and should last a lot longer especially with the grease fittings. Thanks 389932

My factory setup with plastic inserts was worn out after only 10,000 miles. The Dexter trailer suspension equalizer kit K71-449-00 is super heavy duty with brass bushings not plastic. . Wish manufacturers would install this as OEM. 356924
