Absorbs Road Shock and Reduces Chucking

Upgrade your trailer's suspension for a smoother ride with these cushioned Equa-Flex equalizers. These units deliver a ride as smooth as you'd get with torsion axles, but at a fraction of the cost. The rubber cores effectively absorb vibrations and bumps and reduce the back-and-forth movement known as chucking. Unlike standard cast equalizers, the Equa-Flex's rubber cores soak up this energy like a sponge instead of transferring it to your trailer and cargo. The result is a more comfortable ride with less wear and tear on your trailer.


Easy Installation

Illustration of a triple axle trailer suspension system

It's easy to upgrade your trailer's standard suspension with a set of cushioned Equa-Flex equalizers. You will need 18 wet suspension bolts and 12 shackle straps (both sold separately) to incorporate the equalizers into your trailer's suspension system. Four of the suspension bolts will be used to suspend the equalizers from the center hangers, and the other 12 bolts will be used with the shackle straps to attach the equalizers to the double-eye leaf springs. If you would like to replace the bolts that attach the springs to your front and rear hangers as well, you will need 4 additional suspension bolts (sold separately).

Review from a similar Equa-Flex in Trailer Leaf Spring Suspension


We are so happy to learn about etrailer from our friend. Our experience ordering from etrailer was so pleasant working with Crystal. She was very knowledgeable and everything that we needed to replace the springs on our trailer and recommended items that we would need to make our installation perfect! Thank you so much for being available. We will definitely recommend etrailer to our friends and family. 474749

Review from a similar Equa-Flex in Trailer Leaf Spring Suspension


Great product, great company to deal with. Install was a little challenging but worth it I hope. Took trailer for a test run after install, trailer rode smoother. The only thing i could add would be, if I have 2-1/4” shackle plates I don’t need the 3-1/4” plates, maybe reduce the cost a little. 492572

Review from a similar Equa-Flex in Trailer Leaf Spring Suspension


I purchased this product to upgrade my suspension on a brand new travel trailer that I was going to pull to Alaska. I had heard that the roads could be a bit rough and hard on trailer suspensions and did not want to break anything because of the relative inflexibility of the stock system. The product was super easy to install, but I ended up using the longer shackle brackets that were in the suspension upgrade I purchased because I could not get the stock length brackets to line up correctly with the leaf springs. This resulted in a lot more suspension travel than I was anticipating, but seemed to do no harm as a result. The trailer pulled wonderfully all the way to Alaska and back, and did not result in any major upheavals within the trailer. The extra flexibility in the suspension did make it a bit trickier to level the trailer however, requiring greater block thickness on the side that needed to be raised. But ultimately this was no big deal. Ultimately I can only imagine how the stock system would have performed, and my imagination suggests that it would have not been a pretty sight inside the trailer. 694384

Received the equalizer a little after lunch today. Had the passenger side of the trailer done in about an hour after some choice words getting the old one off. Putting this in was simple, and should make a good ride and stop wearing my tire out. 327087

I installed them this spring, here are a few pictures. I also installed all new bushings and greasable pins. It was a good thing I replaced these as the center bushing on my old equalizers were broken. The new equilizers are a couple inches taller than the old one, raise my trailer over an inch. This worked well as my new truck is higher than my old one. 848019

Review from a similar Equa-Flex in Trailer Leaf Spring Suspension


This was a great upgrade. I installed myself, the only issue I had was getting them lined up with the leaf spring. However, I got it figured out and the opposite side went much faster. I think the trailer pulls much better and you don't get the bounce after hitting a bump, RR tracks etc.. Glad that I made this upgrade. If I had one negative, it would be the packaging, the powder coat on one was scratched through. 764473

Have a 30' toy hauler and first added Sumo shocks which made a difference but after adding these Equa - Flex cushioned equalizers what a BIG change in the ride and towing. E trailer shipping was very fast and they were very easy to install . To me this is a must for people with an RV. 721098

Fit finish and performance great. Took longer than expected to complete. Is best done on flat level pad with multiple jacks to get proper alignment. Made huge difference in ride and vibration transfered to the to tow vehicle. Really smooths and quiet ride. Would buy and install again. 717843

  • Best Suspension Upgrade for Keystone Raptor 3712 Toy Hauler Triple Axle
    The Equa-Flex Cushioned Equalizers part # LC279689 is the best suspension upgrade option for a Keystone Raptor 3712 Toy Hauler and what I recommend that you use as it will be a direct fit replacement. The Equa-Flex is pretty much the same thing as the Road Armor which is only for tandem axle trailers. I was recently able to get my hands on the Equa-Flex equalizers and I must say I was very impressed on how well they performed and how easy they were to install. I have attached a review/install...

  • Which Equa Flex Kit is Designed for a Triple Axle Trailer with 7k Axles
    The issue is that when you add an axle to a trailer you have to move all of the axles to allow the axles to sit in the correct spot. Otherwise you'll have ride issues. So your current center hanger location for your tandem setup would become the location for the middle axle center. The Equa Flex kit you'd need for a 7k, triple axle setup is the part # LC279689. I wouldn't recommend having Equa Flex equalizers for the front two axles but not the third one.

  • Suspension Upgrades for a 2011 Forest River Cedar Creek 36RE
    Yes! There are a few options and which set fits will depend on the measurements of your existing equalizers. If the eye center to eye center on your equalizers is 5-1/4 to 6-1/4 inches with a height from the top center hole to the eye center holes of around 2 inches then you can use # K71-652-00. If your equalizer length measurement is 7-1/4 to 8-1/4 inches then you can use # K71-653-00. If your equalizers are 7-1/2 inches long with a height of around 5 inches you can use # LC279688.

  • Possible Suspension Equalizer Upgrade Kit for 2020 Keystone Premier 23 RB
    The widest upgraded equalizer we have for trailer suspension is the Equa-Flex part # LC314336 which is 14-5/8 inches from bolt center to bolt center. This is a cushioned kit that is designed for use with 5,200 lb trailer axles which most likely would work well for you but I'd I verify you have 5,200 lb trailer axles. I attached an install video for this kit for you to check out as well.

  • Could Having Different Axle Spacings on Trailer Contribute to Leaf Spring Failure
    Uneven axle spacing isn't a great sign and most likely is related to the issue. If the leaf springs are the same length and the hangers are spaced differently that would not be the safest setup though and it would be wise to move the hangers to allow you to have even axle spacings. To prevent leaf springs from braking best option is to make sure you aren't overloading the springs that are installed and that all of the suspension components are installed properly in the correct locations....

  • Picking Between Equaflex Models # LC279689 # LC281314 For 2007 Cyclone 3210 with 5.2k Axles
    Your best option is to measure the horizontal distance between the holes of the equalizers you have on the trailer currently and pick the EquaFlex that matches that dimension. The part # LC281314 has this distance at 5-1/2 inches (see first picture), and the # LC279689 has this distance at 7-1/2 inches (second picture). Going with the kit that has the closest dimensions to what you currently have will be your best option.

  • Can 25-1/4" Long Leaf Spring Replace 25-1/2" Long Leaf Spring Currently on Trailer
    Over time leaf springs can stretch out so the 5-Leaf Double-Eye Spring # SP-111275 which is 25-1/4" long, 1-3/4" wide, and rated for a 6,000 lb axle should work great for your application. The Equa-Flex Cushioned Equalizers # LC279689 come with the hardware needed to mount them so as long as you are reusing old shackle straps and bolts you won't need to change anything else out. U-Bolts are a little more specific and since I don't know the tiny details about your trailer I have linked...
