by:

Great kit put together by Dexter! I did find that the eye bolts furthest away from the equalizer were better put in with grease zerk on the inside because the factory bolts had neck ribbing and they are much easier to drive in. The other bolt can all be put in either way .

Still working great !



by:

Received the package damaged with missing parts from USPS. etrailer told me they were going "make it right" and expedite the new package. I just spoke with a manager who told me there was an error in the system that flipped it from expedited to USPS shipping.



by:

Good quality product, bought another set for a different trailer.



by:

Absolutely a perfect fit. I was in a rush to make a trip to Western Colorado and Moab Utah when I noticed all my bushings were shot and had worn into the equalizers. I called Michelle and she had my parts on the way immediately. I also ended getting 4 new tires and wheels. Couldn't be more pleased with Michelle B and etrailer.com I highly recommend them. They have all the parts you need and the service is 2nd to none.



by:

Great product, had these on before a leaf spring busted on me and figured just replace all 6 springs and the hangers. Easy to grease and maintain, fit just like the originals that did not have grease-able bolts. Didn't want to reuse the bolts and nuts from the previous grease-able set I had on it, cheap insurance and peace of mind. Painted the hangers and the leaf springs to match my trailer.



by:

Replaced the old trailer suspension with the heavy-duty suspension kit, U-bolts, and leaf springs from etrailer. Everything fit like it should, and looks like it will last longer than I will.



by:

Overall I’m very pleased with this heavy duty suspension kit. It fit correctly and I’m sure this wet-bolt system will be much more durable than my old dry-bolt system, which at 4 years old was showing major wear, rust, and fatigue. The reason I gave it only 4 stars was because one of the nuts stripped out under very little torque, as if it hadn’t been heat treated and hardened. The bolt was fine. I reinstalled one of my old nuts and it torqued fine to 50 ft. lbs., per Dexter specifications. All other parts were fine.



by:

Excellent service, Excellent product, much heavier duty than original

Great, No issues



by:

Very happy with the product and installation instructions. I anticipate better performance of the suspension with the greaseable brass bushings.



by:

Dexter suspension kit was excellent. Added 14 more grease points which should help with wear. Very satisfied.
Bronze bushings replaced oem plastic in springs.



by:

Perfect product. Easy to install as long as you make sure that the trailer is well supported before banging old shackle bolts out and new ones in. Do not try to hammer the new sleeves into the spring eyes. Use a large C clamp. One of the pre-assembled shackle bolt units was slightly bent, not noticably so, but had to use some heat to install the matching plate.

It is such a great feeling that the springs are now riding on unborn shackles. The old ones were so worn that I am surprised that the springs were still connected to the chassis. Peace of mind is a great feeling.



by:

The hangers are thicker and more robust. The brackets fit tight so be patient. They should last the life of the trailer. Etrailer got them to me quick and they fit perfect.



by:

Very easy to install once you get the old junk off. Major improvement. Great sales personnel. Very helpful quick and easy purchase.

Two Stars for etrailer and 5 stars for Dexter's product.
Order was placed via phone and etrailer got the street address wrong but had the correct name, city and phone number on the shipping label. So I got notified by the receiving person and I went to pick it up.

The box had a lot of tape on it and it was the Dexter factory box which etrailer did not re-box or anything so once I cut though all that tape most likely put on by UPS when they discovered the box was damaged I started checking inventory and sure enough missing 3 shackle plates! I promptly called etrailer with the address mess up and loss parts due to the package not being properly prepped to go though the shipping channels. As I was leaving in a couple of day I asked it they could expedite the missing parts to me and was told no it would take a week. Well I got notice that the package was delivered to my front door but when I went out there was no package from them via ups. Ups did leave my orders from [online] and [online] but nothing from etrailer. So I emailed etrailer requesting the tracking number as they do not provide them with the shipping notice so I could see where it was delivered to thinking they got the address wrong again. Got a response email stating it was delivered! So I called and the guy said it shows UPS left it at my front door and he read off the address which was correct. Then he said while it says that it also says left at local post office! So not a great experience, I would like to see edtrailer allow you to create an acct so you can view current orders as well as past orders and provide an actual tracking number so you can get info straight from the shipping company.

No more squeaky trailer suspension! These are HEAVY duty and give me the utmost confidence trailering cross country! I highly recommend this upgrade!

Excellent! Routinely keep them greased and they are performing great!



by:

Yesterday I completed the install of the Dexter Heavy Duty Suspension,
kit # K71-448-00. The included instructions were pretty good, plus I watched a few YouTube videos before beginning the install. The biggest issue was removing the old bolts from the trailer. Once that was accomplished the new parts went on easily. Now my suspension just looks stronger and with the wet bolts it should last the life of the trailer. The old plastic bushings were pretty well shot and were overdue for replacement. Thanks to etrialer for a great upgrade!



by:

I finally got around to installing the Dexter suspension kit today ( having received it over a month ago ). Installation went very smoothly. The product looks MUCH better than the stock components that were on my Jayco trailer. I believe the capability to routinely lube the pins will make a big difference in performance and longevity. I've ordered many items from etrailer over the years and they did a great job at delivery with good pricing.



by:

I've had a few sets of shackle straps wear out. While replacing them I noticed that the bolts and bushings were badly worn. The equalizer also had heavy wear in the center bolt hole. I decided to replace all of the lighter duty parts with this Dexter heavy duty suspension kit. These shackle straps are much heavier and all of the bushings are bronze. These are also wet bolts, so I'll be able to keep them greased and prevent wear. The parts came in a kit together and were easy to install. Shipping was fast and etrailer honored the lowest price pledge by refunding me 110% of the difference between their price and the advertised price of another seller. I definitely recommend this kit from Dexter and etrailer as the right place to get it.



by:

The parts were all the right ones and most were Dexter oem parts. The only problem I had was putting the bolts in the frame end of the spring perch. It was easier to take the spring loose from the axle, put the bolt in ,then bolt it back to the axle. I intend to buy all of my future trailer parts from etrailer.



by:

This suspension kit was perfect for my Forest River Wolfpack. If you have a 40' camper you need this. It raised the rear height giving more of a level pull, stiffer turns, better off-road less roll and less bounce in the camper when setup. All campers are junk quality, so do yourself a favor and upgrade your suspension.



by:

Great product, great price! Included all the hardware to replace everything that wears in the spring suspension. Made a loose, very worn trailer like new. Also the bushings are greaseable now so should stay that way.



by:

Will make a great improvement without spending a fortune.



by:

Much better quality than the original. We like the ability to grease it. Harder than I expected it would be. Had trouble lining up the springs with hangers and had to use a come along to pull the axle into place. Tough job for a 69 year old. This is what should come on ALL new campers



by:

Perfect, great up grade! Shipped really fast.



by:

Very quick turnaround and I appreciate the follow up emails to keep me informed. I am a regular customer and the great people at etrailer never disappoint!!!! I will make one recommendation. Have shipping put some tape on the box. I did get everything but the box basically fell apart and I am sure the delivery guys would have appreciated taping the box up.

  • Replacement Landing Gear and Equalizers for a 2008 Keystone Cougar 5th Wheel
    Thanks for the pictures! Based on the weight of your 2008 Keystone Cougar 5th Wheel, you will want the item # LG-1 landing gear set. You are going to want to measure to be sure this is the right size for you. The two things you will want to measure will be the distance of the black outer tube of the jack and the distance between the frame clamps (this measurement can differ depending on where the weld stops are located).

  • Dexter Triangular Equalizer Kit With Wet Bolts And No Grease Zerk On Top of Equalizer
    Randy, I have a couple routes you can go since the grease zerk on the Dexter Heavy-Duty Suspension Kit # K71-448-00 is not going to fit inside your hanger. We do have the Triangular Equalizer # TREQ310 but this comes with nylon inserts so you would need to swap them for Bronze # D014-077-00 if you wanted to have Wet Bolts # MR46ZR. Otherwise you could use the Kit # K71-448-00 and swap out the standard pivot bolts which come with the kit for the Wet Bolt # MR92HR and Nut # MR85DR. The...

  • Recommended 14-1/2" x 3" Tall Equalizer and Replacement Shackle Kit
    To replace your 14-1/2" x 3" tall equalizer you will want the Curved Equalizer for 1-3/4" Wide Double-Eye Spring item # K13-142-02. This equalizer is slightly larger at 14-3/4" but will still work for your trailer. For upgraded shackles and wet bolts you will want the MORryde Suspension Upgrade Kit for Tandem Axle Trailers item # MR46ZR (2-1/4" shackles) or item # MR76ZR (3-1/8" shackles). These kits come with the bronze bushings, wet bolts and shackle straps.

  • Recommended Dexter E-Z Flex Upgraded Equalizer to Replace Existing 4 Inch Tall Equalizer
    You could use the Dexter E-Z Flex # K71-652-00 tandem axle suspension upgrade kit for 6K axles or # K71-653-00 for 8K axles. If you used the # K71-652-00, you'd need an equalizer hanger about 2 inches longer to make up that height difference and not throw off your suspension geometry. Or, you could use a shock absorbing equalizer that has the same approximate height as your existing equalizer like the Lippert Road Armor, part # LC696740 which is good for 3500-8000 lb axles, which wouldn't...

  • How to Find if Dexter Heavy-Duty Suspension Kit Will Fit on Trailer
    The equalizers that come with the Dexter Heavy-Duty Suspension Kit # K71-448-00 have bolt holes that measure 6" apart on center and then 4" tall on center as you can see in the attached photo. You'll want to measure your current equalizers to see if they have similar dimensions or not. If they do then this is the kit for you. If they don't then just let me know what your measurements are and I can help you choose the correct replacement suspension kit from the linked selection.

  • Can 4" Tall Equalizer Be Used To Replace 3" Tall Equalizer?
    You are correct. The Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double-Eye Springs # K71-448-00 you were looking at is 4" tall meaning it slightly will lift your trailer. These equalizers are slightly shorter at 6" wide but since it is within 1/8" you wont have any issues. I included a diagram showing the dimensions of the # K71-448-00 and a video review for you to take a look at.

  • Dexter Suspension Kit For Tandem Trailers With Equalizers Measuring 7-3/4, 6, or 5-3/4
    The Dexter suspension kits are high quality and include "wet bolts", bronze bushings instead of nylon and thick shackles. Properly maintained these would likely outlast typical factory kits three times over! To determine which kit is right for you simply measure the distance across the equalizer and use item # K71-449-00 for 7-3/4" long, item # K71-448-00 for 6" long, or item # K71-359-00 for 5-3/4" long.

  • How To Choose the Correct Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers
    I don't have any information as to what leaf springs are on any one particular trailer such as a 2007 Jayco Jay Flight 29BHS but if they are double eye leaf springs which are the most common then we should have a Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers that will work. In order to choose the correct one you just need to make note of the equalizer dimensions; part # K71-449-00 for 7-3/4" long, part # K71-448-00 for 6" long, or part # K71-359-00 for 5-3/4" long.

  • Determining The Correct Replacement Leaf Springs For Tandem Axle Trailer W/ Square Axles
    I would be happy to help you find the correct replacement suspension components for your trailer, but you will need to take a few measurements first.

    To get the amount of lift you want and having tandem axles, you will need QTY.3 of the Correct Track Trailer Alignment and Lift Kit # LC87120. This will cover all 6 hangers and will give you 1-1/4" or 2-1/4" of lift.

The metal is the exact same but the coatings are different.

  • Should There be Gaps between Trailer Suspension Components After Hardware is Installed
    Trailer suspension needs to be able to move to function properly. If you were to tighten down the shackle bolts and nuts to point that all gaps were removed and the components were tight to each other you'd have suspension that doesn't move. So you can leave the gaps you have now and everything will function fine.
