All together this is a great upgrade and the components themselves fit well and as described. Only 3 stars on the review though and here's why. First, the items were very poorly packaged and several of the linkage bolts had protruded through the packaging and were damaged. About an extra hour and a few specialty tools were required to file and re-tap the threads, luckily I have easy access to the tools. Second, the kit contained too many center equalizer mount bolts and too few outer wet bolts. I was again lucky that this didn't cause a big set back as I had kept extra wet bolts from a past trailer repair and had them on hand. Although having nothing to due with the kit itself but due to the design of the front equalizer, I encountered clearance issues on the middle hangers. The hangers on my 09 WW LE3305 have gussets welded inside of them from the factory which had to be clearance to clear the zerk fittings. I also had to modify the hanger for the front equalizer to allow clearance when mounting the hanger in the upper hole, I believe it may have been okay in the lower hole without modification. Overall I am happy with the product and the excellent service that etrailer provides.

My 10 year old Toy Hauler was in need of some TLC. I dry camp 98% of the time. Traveling down very dusty and bumpy roads. The factory equalizers had plastic bushings that had failed. The Dexter Ez-Flex came with new bronze bushings and all of the hard-ware. It took me and a friend approximately 5 hours to install these. I have only pulled the trailer once since the install, but I could notice a difference right away. I like the fact that there are bronze bushing and I am able to grease them myself. I highly recommend this product if you do a lot of dry camping and going down rough dirt roads. I should not have any other problem with my load equalizers. The staff at etrailer was very helpful Rick S. and Michelle S. keep me informed each step along the way. This is the second big purchase I have made with etrailer and I highly recommend them and will use them again. Thank You

This is an excellent upgrade from what came stock on the trailer. It is heavy duty, rides great and is very well made. I will be upgraded my other trailer with this kit soon. My only complaint is with the packaging. It was damaged in shipping and missing two straps, etrailer sent two replacements out right away. The smaller parts need to be put in a separate box or something.

The product is sturdy and built well. I already had prior experience with Dexter parts and these are manufactured with the same high quality. The instructions were easy to understand, and the Install Video that e-trailer had was EXTREMELY helpful. My installation went perfect and I had no issues. I road checked after and it felt smoother. Headed out this week for a 300 mile trip! Thank you e-trailer!

This system made my 30' three axel equipment trailer ride like a Cadillac! Its so smooth when empty I almost forget I'm towing it. With a 13,000 lb excavator on it it's smooth as silk. I'd recommend this system to everyone who has a trailer.

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


These are are direct replacement for the stock equalizers on my Dexter D44 4400lbs axles. They were very easy to install and have done a great job smoothing out the ride of the trailer. They are a lot heavier duty than the stock equalizer. So far I have been very impressed. If they last for a number of years I will be very happy

After a year these are still working great. They have done a lot to smooth out the trailers ride on the terrible roads.

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


Great product. Not an easy installation but well worth the effort. Tuffest part is getting the old bolts out and the new bushings and bolts pressed back in. I found I could not effectively pound them out or in as directions suggests. I made a simple tool using a large C clamp and two sockets to press the old ones out and the new ones in. Picture enclosed

A great improvement. I certainly recommend this upgrade.

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


Bought this kit last year for a tandem axle car hauling trailer. The original equalizer and bushings were just wore out from normal use. The wear was creating lots of extra vibration and noise. Thought I would give this a try. I am beyond impressed. The trailer now tows and rides as good as one of my other trailers that has torsion suspension. Vibration from axle misalignment and rattles are gone! I am so impressed I have now purchased another kit for my 5th wheel camper. Have not had the 5th wheel out yet but my expectations are pretty high after the improvement I have experienced with the other trailer. Some would argue that since my camper has shocks this is redundant. My answer to that is, "shocks and springs have different jobs". Very easy to install. Only took 2.5 hours total for both sides.


Comments
Over a year now and about 18k miles. Still impressed! The improvement on my 5th wheel just as impressed as with car trailer.

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


My trailer was due for some maintenance cuz everytime I was returned when the axles twist there's a lot of popping crack on going on this is when you know you need to change out the bushings and shackles. But with these pins you can keep the pins greased. I have 6540 lbs inside trailer all the time. So now the trailer rides a little. Plus the it quiet things up when I now turn.

The ride is so much smoother

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


etrailer support staff gets 5 stars. However... The kit I received was incomplete. Bushings were missing, two shackle links and a shackle link assembly were missing. Additionally, one of the shackle link assemblies would not accept its' mating link - the bolt shafts were spread apart. one of the equalizer assemblies did not have that gold anodize coating, another had incomplete anodize coating. see pic. etrailer staff shipped me the bushings and the shackle link assemblies to complete my project. As for the finish, POR 15 gloss black is a lovely color. The issue here is with Dexter, not etrailer

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


Very happy with them, and had them on for about year. They are working well, I also bought new leaf springs too, plus I upgraded the new disc & rotors, electric hydraulic pump, breakaway braking system along with them, plus flipping the axels, and new shock kit. The whole job was a little bit of money, but, thinking it was well worth the effort, time, and money. She [ The Hillbilly Hillton ], a customer cargo trailer, is a real pleasure to tow around and was really made to go offroad and explore the back country. She rides like butter! : ) All parts came from etrailer, they had everything I need

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


I like the equalizers, no more squeeking, coupled with the heavier leaf springs i have a better ride. Only one of the four doors/drawers pops open during travel now. I did have problems installing them, the axle was difficult to get back in place on one side, if I had jacked up the whole trailer (all four wheels off the ground) it would have been a lot easier, live and learn. Oh, had my 18 year old granddaughter and two of her girlfriends do almost all of the work as I had minor surgery on my shoulder a week before we did the change out, they wanted to do a 5 day campout with the trailer so the broken leaf spring had to be replaced. Very satisfied with them, the girls work and the equalizers.

No change, the equalizers and springs are working well. I am happy I made the change.

After installing my new E-Z Flex Suspension kit a year ago I have travelled close to 25k with out any problems and it held up even after breaking a leaf spring and then later the leaf spring bracket that is welded to the frame. I am super impressed with this product and wonder why Heartland does not use it when they build there trailers.

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


Unbelievable increase in stability when towing, especially in cross winds. Worth it, but it may take multiple jacks, prybars, a helper and some time to get these installed since the more tweaked your suspension was, the harder it will be to align the pins with the leaf springs, so consider paying a suspension shop to do the job... unless you like a challenge.

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


I gave it a 1 star for the lousy installation. I will probably give it a 5 star for how it will work. I have not pulled the 5th wheeler yet, but it looks good. The install looked so easy on your video. Totally not so. Needed 2 jacks, 1 bottle jack and 2 jack stands and 2 1 foot 2x4s. A real pain in the butt to get the bolts back into the spring eyes, but I made it.

Absolutely fantastic, was camping on the coast in Mendocino in February to get there the a stretch of road is about 60 miles thru the mountains, lots of pot holes and signs saying rough road I kid you not, on such a long winding road we definitely knew it was a great investment, knowing we have this Dexter axle installed on the travel trailer

Review from a similar E-Z Flex in Trailer Leaf Spring Suspension


Installed these beauties... The original shackles were rusty and wearing out and ready to fail ... I’m really not sure why a manufacturer would go cheap on the suspension.... Installed rather EZ and took my rig on a 700 mile round trip... It gave me confidence that the trailer was on a good foundation... My 30’ 2002 Holiday Rambler is almost ready for the Route 66!

    Since your current equalizers are 7-3/4 inches the EZ Flex kit part # K71-657-00 that you referenced would fit and work well as a replacement. The ride height would not be significantly changed either. While you do have a unique looking suspension hanger on your trailer this would easily fit the same way.

    The 15,172-lb unloaded weight of the Forest River triple-axle toy hauler 395AMP is potentially getting pretty close to your Silverado 2500's towing limit by the time the trailer is loaded up, so the first thing I suggest is making sure the trailer is loaded in such a way that you have enough pin weight. Too little pin weight can lead to handling issues like sway and bounce. 5th wheel pin weight should be 20-25% of the gross trailer weight. When transporting several 4-wheelers, for example,...
