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.

I just got them I have not installed them yet. I was a little disappointed and the time it took to get them from the time I ordered them they seem to keep adding a day onto each day, but I have them now



by:

Was totally surprised how fast and efficient my order was received ordered on Saturday was delivered Monday morning



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.

I'm sorry to hear about the zerk fitting busting off, Pierre. Let me know how your first few tows go and if you notice any issues at all.

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

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


by:

Etrailer had a back order on these once in stock they shipped them all most 2 weeks sooner than first thought they could. Great service and every knowledge on there products. I have not installed them yet as forest river and my cannot seam to repair my unit correctly which going on the forth month now which has nothing to do with etrailer or morose



by:

much smoother ride



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:

Noticed a big difference in ride towing trailer compared to morryde cre3000



by:

Very good i would recommend these parts again. They assist me very professional.
Thank you so much.



by:

Much better than the 3000



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.



by:

5 star of course. Needed help getting the correct moryde equalizer and wet bolts. Aaron kept in touch even notified me when parts were delivered.

Service like this.... I am a customer for life.

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:

Just what I expected. Great upgrade



by:

Great upgrade. After years of travel, it was time. Great fit and installation went ol



by:

They greatly improved the ride of our 2001 Montana. Things inside aren’t being tossed around like they were before we installed them. I watched them from the side when it was moving forward slowly and I couldn’t believe how they moved to the ground roughness to keep the camper from getting thrashed around.



by:

The plastic buffer is cracking and not sure if it should be fixed.



by:

These made a huge difference when hauling my 5th wheel. Easy to install.



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.

Update after 1 year. Ride quality has substantially improved over the stick setup. I just completed a 2 week 3000 mile round trip journey and had no issues. The suspension system is working well



by:

Neither good or bad. I don’t notice any difference in ride in the tow vehicle. May be better in the trailer but who knows without putting a meter in there and comparing.



by:

It appears our 5th wheel travels smoother. We had a bit of a hiccup on the install but
Once we got proper information from mooryde we were able to install properly.
We highly recommend this system to improve ride of any dual axel 5th wheel or trailer.



by:

Product was great. I ordered the X-Factor crossbar. They need to update the video in that installation because, the video shows it mounting to the rear of the equalizer but if you install the MORryde equalizer,then you need to use the wet bolt that comes with the cross member. FYI open all boxes and read every instruction book before starting so that you don’t have to pull off all the tires again.



by:

Installed the CRE3000 on previous 5th wheel & it improved the ride & handling.
Installed the AllTrek 4000 which is heavier 5th wheel. Have not driven the rig yet, but i expect the same results as the CRR3000.
I would highly recommend the installation of the upgraded hangers.
Completed installation in approximately 6 hours.

  • 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...

  • 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...

    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 David. Based off of wheel base the MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers item # MR29DR is going to be the closest option. However, I recommend measuring one of your current equalizers so we can be sure this is the best fit. A longer or shorter equalizer will throw off the geometry of your suspension. The MORryde AllTrek 4000 Equalizers 35" Wheelbase item # MR29DR has a hole spacing of 8" from center hole to center hole. The MORryde AllTrek 33" Wheelbase item # MR89DR...

    Hey Joe, welcome back! With a 35" wheelbase the MORryde AllTrek 4000 Equalizers for Tandem Axle Trailers # MR29DR is the correct fit. I verified your Reflection has 6k axles on the Grand Design parts site so the # APUBR-8 is also correct and so is the capacity on the # e88SR. Did you account for the leaf springs flattening out over time? Assuming you did, these will work as a replacement with the 26" eye to eye measurement.

  • 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.

  • 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...

  • Will MORryde X-Factor Crossmember Work With AllTrek 4000
    Hey Jeff! I'm not sure who told you that but the information is incorrect. The MORryde X-Factor Crossmember can be used with the AllTrek 4000 like # MR29DR. The correct X-Factor crossmember is the # MR33WR which is the same as the XF12-001. You can see the compatibility chart from MORryde attached below.

  • 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.

  • Will Roadmaster Comfort Ride Shock Absorbers Improve Ride With AllTrek 4000 Installed
    Hey Bruce, welcome back! Adding the MORryde AllTrek 4000 # MR89DR (33" wheelbase) or # MR29DR (35" wheelbase) will improve the ride on your Fox Mountain 235RLS. Adding the Roadmaster Comfort Ride Shock Absorbers # RM-2460 will be a significant improvement on top of that. It is hard to say if just the equalizers is "enough" since that depends on a lot of things. I have upgraded equalizers (Dexter E-Z Flex) and they did improve the ride quite a bit. If we towed more often I would definitely...

  • What Upgraded MORryde Equalizers do I Need for My 2022 Pioneer BH270 Travel Trailer?
    Hello Martin, Happy to help you get into the right equalizers! I don’t have a database that tells me exactly what was installed on each trailer, so we’ll need to rely on a quick measurement to make sure you get the correct fit. You asked about the AllTrek 4000, which is a great option! We list it by wheelbase on the product page, but since there isn’t a true standard for trailer suspension, the best way to match it is to what you currently have. You’ll want to measure the hole to hole...

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

  • Can I Use the MORryde CRE4000 to Lift My Trailer?
    Hi Bill, The MORryde AllTrek 4000 Equalizer part # MR29DR is not intended to raise the height of your camper, it would offer little to no lift. The 4" of suspension travel listed on the product page is in reference to how much the suspension can move up and won to absorb any bumps in the road. Instead, to lift your trailer I suggest using an over-under conversion kit to "raise" the axles by moving your leaf springs over the axle and give you more clearance.

    Hey Doug! More than likely the Lippert Center Point # LC1565391 will fit your 2017 Jayco 2035 RKDS. The system is designed for standard center hangers at least 3" wide and measuring at least 2-1/2" from the equalizer hole to the top of the hanger. Hanger spacing must also be 29-1/2" or 30-1/2" apart. As long as you meet these requirements it will work. Any big trips planned with your Jayco this summer?

The first is the 4000 is constructed with 40% more rubber than the CRE3000, which means more shock absorption as you tow. It also has another inch of suspension travel, 4" compared to 3", that further smooths out your ride.

    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...

The wheelbase is measured from the center of the front wheel to the center of the rear wheel. I'm not sure what this is on your Grand Design, but it's a fairly simple measurement to take. While you're out getting the wheelbase, I also recommend measuring the length of your shackle straps center to center. This will tell you if...
