Video Transcript for MORryde Tandem Axle Trailers AllTrek 4000 Equalizers Review

Hello neighbors, it's Brad here at etrailer and today we're taking a look at the MORryde AllTrek 4000 Suspension Equalizer. Now our previous equalizer here you can see that it does have rubber and that's gonna allow this to kind of move up and down and have that cushion. These are pretty loose here, which is fine. It does have that movement and each of them are about I'd say an inch and a half. So you have some movement up and down and that's where putting it side by side you can see the AllTrek is not only it seems like it's a little bit taller but that's because you have four inches of movement here because you have this rubber that's supporting that weight, and as this moves up and down it's gonna be nice and even it's not gonna be sloppy and you're gonna get more of that suspension travel which allows your suspension to move a little bit more giving you a better ride overall. And that's gonna not only make for a smoother ride and kind of just be easier on your camper and it's contents but also that's gonna transmit all of that energy up to the pin box.

So it's really gonna cut down on that porpoising because the suspension can kind of settle out and take those bumps away from your connection point. Now this is bolt on installation. In fact, you can reuse your old wet bolts. What I've found, you might wanna pick up a new wet bolt kit while you're here. That way you have, you know, all new components a new hardware in place.

Now it's not required to have a crossmember kit as well. We are gonna be putting one on here. So yours may not look like this but it is not required to get this installed. Not only are you gonna get more suspension travel allowing the suspension to work better but you also have 40% more rubber absorbing those shocks. It's also gonna be progressive so as it kind of presses up, it's gonna fight against that and really settle out the suspension.

So having a little bit more cushion and more travel just means that suspension can really do what it needs to do. Now this does come as a quantity of two so it's gonna allow you to get your tandem axle set up with the one kit. But if you do have a triple axle you are gonna wanna pick up another kit. That way you can get all of your equalizers done. Installation is pretty straightforward.

You are just kind of bolting it in and you will have to get your old wet bolts out which kind of can be a struggle. And you will have to obviously take your wheels off and be able to support the axles. Might wanna have a floor jack ready too just to kind of move it as you need to to get some of your hardware in place. But overall, it's not too bad to do. Now here's what they're gonna look like installed and this is gonna be a great pretty easy upgrade to install. It's gonna give you a lot better suspension because of the ability to have a little bit more travel. And that just means a better towing experience overall. And that was a look at the MORryde AllTrek 4000 Suspension Equalizer.

Welcome to the etrailer family, Jim! I'm glad that Aaron was able to get you exactly what you needed for your trailer. We will be here to help with your next project.



by:

Not a simple install, but doable. You're dealing with the weight of the axles connected to leaf springs, and trying to align holes for mounting bolts while "the other" spring is shifting and pivoting...
Again, not impossible, but took some finagling (midwestern word for 'place second hydraulic jack at an angle to push equalizer that way while blocking the other spring with a metal thing and preventing this spring from pushing too high in bracket...) Don't expect it to be bing bang boom, done.

@Eric Nice! How much of a difference did you feel with the ride quality?


by:

My 35 foot fifth wheel experienced much less bucking while traveling. I was extremely satisfied with the results verses the investment.



by:

Installed this on my 2019 Grand Design Momentum 328M. Replaced the existing factory Lippert Equa-Flex system. Installation went smoothly, also installed the Moyride upgraded shackle and wet bolt kit. I chose the mouride because I found that the brass inserts for the wet bolts on the Equa-Flex system were toast and couldn’t be easily replaced due to the size of the brass insert. The Morryde system seems to have replaceable brass inserts. Just installed today so can’t do any comparison or review on ride quality just yet.



by:

Paul was super helpful in getting my order filled properly and delivered in a timely manor. I am excited to install the product on our 5th Wheel to get a smoother ride with more security on the springs. The increased travel and sturdiness of this product is something I know will make our trips more enjoyable and give us that extra peace of mind.



by:

Products arrived one day late but products were as described and very pleased with the installation.



by:

I'm not sure how this product will hold up to the abuse it is intended for. Why? Because one of the grease zerks busted off the wet bolt as I was finishing up the install. I was able to remove the busted off threads and put a better grease zerk in and finish up. Time will tell how it holds up and performs. Not really sure if it was worth all the money and time to swap out the old bolts and equalizer because nothing was worn out. I think it took about 6 hours to do the whole job by myself. Hardest part was just getting it all back together. I usually haul the camper about 5,000 miles a year so we'll see how it all performs.

  • Want To Upgrade From CRE 3000 Suspension On 2023 Grand Design Momentum 336M
    Hello Lanny, thanks for reaching out. The CRE 3000 is already a pretty good suspension system, but if you want to upgrade, the first thing that comes to mind are the AllTrek 4000 equalizers. They have more rubber than the CRE 3000, 40% more, so you will get a lot more effective shock absorption. It also adds another inch of suspension travel. This will definitely be the best option for an upgrade that does not require any major modifications. You will just need to select the correct equalizer...

  • Upgrading Suspension Equalizers On 2018 Prime Time Trace Air 275 Travel Trailer
    Hey Scott, I can certainly point you in the right direction for picking out an equalizer upgrade kit for your 2018 Prime Time Tracer Air 275 travel trailer. You will need to measure your wheel base (aka axle spacing) to determine if you need MORryde ALLTREK 4000 Shock Absorbing Equalizers for Tandem Axle Trailers - 33" Wheelbase - 8K # MR89DR or the 35" Wheelbase version # MR29DR. This measurement is the center of the front axle to the center of the rear axle. For the wet bolt kit, I...

    Hey Nick, thanks for reaching out! The MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers # MR29DR will work as long as you have a 35" wheelbase (center axle to center axle) and it meets the specs in the attached photos for the qualifier.

  • Should I Switch Out My CRE3000 Equalizer for the CRE4000 Equalizers? How are the CRE4000's Better?
    Hello Jay, So, the good news is that yes, the CRE4000 # MR29DR can work with your 2023 Grand Design Imagine 2500RL. It’s built for tandem axle setups with axle ratings from 3,500 to 7,000 lbs, just like the CRE3000. As long as your axle spacing is the standard 35 inches (which it usually is on the 2500RL), it will fit great! Where the CRE4000 really stands out is in performance. It gives you an extra inch of vertical travel (4 inches total vs. 3 inches on the CRE3000), and it includes...

  • MORyde Cushioned Equalizer that Fits 2017 Jayco Jayflight 212QB
    Hey Mike, since your wheelbase is 33 inches the correct MORryde Alltrek is the part # MR89DR. The distance between the bolt holes left to right is 6-1/2 inches which is close enough to what you have and the vertical dimension is 4-1/2 inches which is also close enough. The correct shackle kit would be the part # MR46ZR which is 2-1/4 inch like you mentioned as well.

  • Best Equalizer Suspension Upgrade Recommendation for 2023 Grand Design Imagine 2760MK

  • Comparing MORryde AllTrek and SRE4000 Premium Rubber Suspension Equalizers
    The MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers # MR29DR are the new upgrade to their counterpart - the MORryde Premium Rubber Suspension Kit for Tandem Axle Trailers MR47ZR. According to MORryde, the AllTrek has been through more intense testing than any of their other equalizer systems and since it doesn't have to have the crossmember that's just an added bonus. Unless you like the idea of having that extra crossmember, I recommend going with the AllTrek.

  • Is It Worth Upgrading to MORryde AllTrek 4000 From CRE3000 on Jayco 5th Wheel Trailer
    Hey Luis, We can answer both your questions in one as yes, you can change from the CRE3000 to AllTrek 4000, and it's definitely an upgrade worth making, as the AllTrek 4000 is better in a couple ways from the CRE3000. The first is the 4000 is constructed with significantly more rubber - 40% - than 3000, which means more shock absorption as you tow. It also has another inch of suspension travel - 4" compared to 3" - to further smooth out your ride. So this is a true upgrade to make towing...

  • Cushioned Equalizer Recommendation for 2006 Eclipse Attitude 21AK
    Hey Sherry, I really like the MORryde AllTrek 4000 cushioned equalizer kits like the part # MR29DR for 35 inch wheelbase or part # MR89DR for 33 inch wheelbases. Reason being this is only option to have vertical and horizontal cushioning. Is your ride quality pretty rough?

  • Replacement Pin Box Option For A Lippert Turning Point Rotating Pin Box
    The Lippert Turning Point has a specific bolt pattern that only has one replacement so far, the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box # GY48GR. This is a gooseneck adapter though so you'd have to switch out the hitch for a gooseneck ball for this to work. The torsion head will help reduce road shock and chucking transferred to your truck so it is worth considering, but you'll also be moving your pivot point back to the truck so you could run into clearance issues if...

  • Best Cushioned Equalizer and Shackle Kit Recommendation for Tandem Axle Trailer w 33 inch Wheelbase
    Hey David, it sounds like you have the correct length equalizers on your trailer based on the shackle angles you mentioned. Sometimes the equalizer lengths do match up with the wheelbase like you mentioned but it's not always the case as leaf spring lengths vary which throws everything off. I would say that sticking with the length you have now is the best option so for a cushioned setup I would recommend the Alltrek 4000 part # MR29DR which is correct size and provides the best cushioning...

  • Are ALLTREK 4000 Cushioned Trailer Suspension Equalizers the Best Available
    The AllTrek 4000 kits provide the best cushioning so if you were to upgrade from your CRE3000 kit to the Alltrek you would see a big improvement. If you have a 35 inch wheelbase you'd want the part # MR29DR or if you have a 33 inch wheelbase you'd need the part # MR89DR. These kits have vertical and horizontal cushioning unlike all other options so they are going to make a huge improvement.

  • How To Select The Correct MORryde AllTrek Equalizer For a Tandem Axle Trailer
    The best way to find the correct replacement for your equalizer is by measuring the distance from the front shackle hole to rear shackle hole on your current equalizer. The 33" AllTrek # MR89DR has the holes spaced 6-1/2" on center while the 35" AllTrek # MR29DR spaces the holes 8" on center. While the MORryde qualifier is very helpful I find that measuring is best since different trailer manufacturers do not always follow the same practices for welding on the spring hangers and setting...

    I have a couple options for you to replace the suspension on your 2019 Grand Design Solitude 380FL 5th wheel camper. First the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 which I see you already found is one option. The benefit of this is you get a more independent suspension on the axles so as one axle goes up over a bump it does not affect the wheel and tire behind it. Best of all everything including shocks comes in one kit. If you would rather...

  • Is It Okay To Mix & Match Lippert Cushioned Equalizers With MORryde Shackles On Tandem Axle Trailer?
    It is okay to mix and match the Lippert Road Armor # LC696740 with the MORryde 2-1/4" # MR46ZR or 3-1/8" # MR76ZR shackle straps. The MORryde shackles are superior in construction to the Lippert kits we currently carry. MORryde did just release their MORryde AllTrek 4000 Equalizers # MR29DR. These provide up to 4" of suspension travel in the equalizer alone which is much greater than than Lippert offerings. We have installed this on a few trailers so far in our shop and have been very happy...

With the Road Armor bolts only spread 6" on center and your current leaf spring sitting relatively flat I worry going to the shorter equalizer may cause the shackle to flip on the equalizer more easily.
