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



by:

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:

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:

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



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:

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.

  • Replacement Equalizer, Shackles and Shock Kit For a 2022 Nash 23D Travel Trailer
    The Triangular Equalizer # TREQ310 is a replacement for the Dexter 13-10 on your 2022 Nash 23D travel trailer. You should consider upgrading to the MORryde ALLTREK 4000 Shock Absorbing Equalizers # MR89DR. These will pair with either the 2-1/4" # MR46ZR or 3-1/8" # MR76ZR shackle kits depending on the length from center hole to center hole on your shackle links. While we do not carry the same KYB shocks installed by Nash we do have the Lippert Bolt-On Shock Kits. These are available for...

  • Recommended Cushioned Equalizer Replacement Options For Factory Equalizer 6" Wide and 4" Tall
    I understand your worry Tom, and I have a couple recommendations. First is the MORryde ALLTREK 4000 Shock Absorbing Equalizers # MR89DR which has a height of 4-1/2" for the mounting bolts. This is also 6-1/2" in width like the shorter Equalizer # MR87ZR and don't worry the additional width as the shackle straps will accommodate for the difference. If you chose either the shorter MORryde or Road Armor # LC696740 you may be able to switch to a shorter shackle strap. If you have the longer...

  • 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...

  • What is the Difference Between the MORryde CRE3000 and AllTrek 4000 Suspension Kits
    Hey Ian, great to hear from you again! The differences between the MORryde CRE3000 # MR87ZR and AllTrek 4000 # MR89DR that fit a 33" wheelbase is the height between the hanger and equalizer bolts, and the amount of travel the suspension style will offer. For the CRE3000 the height distance is 3-1/4" and it can have up to 3" of travel, while the AllTrek 4000 has a 4-1/2" height distance, and it can have up to 4" of travel. I personally like the CRE3000 a little better so I recommend going...

  • 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...

  • 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.

  • Upgraded Equalizer to Replace Dexter 13-10 Equalizer on 2015 Heartland Prolwer P289
    Hi Myles; the best upgraded equalizer is typically the one that is the closest match to your stock equalizer. The 13-10 is the same as the # TREQ310 which is 4" tall and measures 6" between the outer shackle bolt holes. the MORryde ALLTREK 4000 # MR89DR is 4-1/2" tall and measures 6-1/2" between the outer shackle bolt holes making it the closest match in height and width. This means the ALLTREK 4000 would be a good replacement for your Dexter 13-10. I also recommend adding the MORryde...

  • 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 Trailer with 33 inch Wheelbase
    For a trailer like your 2017 Shadow that has a 33 inch wheelbase the best cushioned equalizer upgrade is the MORryde ALLTREK 4000 part # MR89DR which is only option that has vertical and horizontal cushioning. To upgrade your shackles you'd want the part # MR76ZR for if you need 3-1/8 inch shackles or part # MR58ZR for if you need 2-1/4 inch. This comes with new bushings, wet bolts, and heavy duty shackles.

  • 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?

  • Correct Orientation of MORryde ALLTREK 4000 Shock Absorbing Equalizers
    It looks like your MORryde ALLTREK 4000 Shock Absorbing Equalizers # MR89DR are longer than your previous equalizers were because your leaf springs are way too close to each other. The shackles should be creating more of a "W" shape instead of being all scrunched together like what your photos show. I'm attaching a photo of what the system should look like when it's installed. You definitely should have the shop that did the installation for you fix what's going on. At the very least you...

  • Upgraded Equalizer for 2021 Wildwood X-Lite With EQ310 Equalizer
    Hey Dan! I don't have an exact reason for the measurement restrictions on one vs. the other. It is what MORryde has found works based on the designs. Regardless, the best replacement for an EQ310 like yours is the MORryde ALLTREK 4000 # MR89DR. That particular equalizer isn't as common and has that extra height to it. The ALLTREK 4000 is the closest match (which is the most important factor) and will keep your suspension geometry the same. While you're at it, I also recommend adding the...

  • 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...

  • Best Cushioned Equalizer Replacement for Equalizer that is 6 inches Wide
    The absolute best cushioned equalizer that fits the dimensions you mentioned having would be the MORryde ALLTREK 4000 part # MR89DR as this is only option to provide vertical and horizontal cushioning. This would make a big difference and you'd be really happy with it. Then for an HD upgraded shackle kit that comes with brass bushings and wet bolts you'd also want the part # MR46ZR.

  • Cushioned Equalizer Recommendation for Trailer Suspension
    Hey Rich, so I am not totally sure what components you are looking for a recommendation for but since your question came in off the Dexter EZ Flex part # K71-652-00 I would assume you are looking for a set of cushioned equalizers. For that I would recommend the MORryde AllTrek 4000 kit part # MR89DR as it's only option that has vertical and horizontal cushioning. This also fits the same 33 inch wheelbase as the EZ Flex kit you mentioned. If instead you have a 35 inch wheelbase what you...

  • Will MORryde AllTrek 4000 Replace 5-1/2" Equalizer
    Choosing the MORryde AllTrek 4000 # MR89DR comes with more requirements than simply matching up the size. At about 5-1/2" you should stick with the Equa-Flex # LC279687 from before or the Dexter # K71-652-00 which you can see installed on my trailer below. The # MR89DR is designed for a trailer with a 35" wheelbase. It also requires 15" or larger wheels for an overslung axle and 16" or larger for an underslung. In addition to this there are clearance calculations to be made. See the diagram...

    Hey Chad this is a great question. So the MORryde ALLTREK part # MR89DR does offer additional vertical suspension but it does sit a little taller than the equalizers it replaces so you wouldn't have to worry about your tires hitting fenders or anything.

    I can get the parts from that video but what I don't know 100% is the bolt size on that brake kit. Based on our own installation video I believe it is the 1/2". It is also worth noting that the brakes are designed for 7k axles with # 25580 inner and # 14125A or # 02475 outer bearings.

  • Do Leaf Springs Need to be Changed Going to AllTrek 4000 Equalizers
    Hi David; nope, the leaf springs don't need to be changed if going to the AllTrek 4000 equalizers. You just need to choose the right one based on your wheelbase (measured center-to-center of your wheels): - 33" Wheelbase: MORryde AllTrek 4000 Shock Absorbing Equalizers # MR89DR - 35" Wheelbase: MORryde AllTrek 4000 Shock Absorbing Equalizers # MR29DR

  • Replacing/Upgrading Equalizer On A 2012 Heartland Greystone 27RK Fifth Wheel
    Hello Chris, it sounds like you are definitely on the right track here. When replacing an equalizer, it is critical that the replacement equalizer is identical in size to the original equalizer. There is a small amount of tolerance there, like maybe 1/2" or less. I will also add that you really cannot select an equalizer off of only the wheelbase measurement. With the current equalizer being only 5" from hole-to-hole, the MORryde ALLTREK 4000 # MR89DR is going to be much too large to be...

  • Cushioned Equalizer Recommendation for RV with 31.5 inch Wheelbase
    The MORryde ALLTREK 4000 part # MR89DR should fit but you'd need to measure your equalizers first to be sure since your wheelbase is not one of the more common ones. If your equalizer has a distance of 6-1/2 inches between the bolt centers (or pretty close to that) this kit will fit and give you the best cushioned equalizer setup out there as it has ability to cushion vertically and horizontally.
