Features to know about
Smoother Ride Over Rough Roads: Rubber Shear Springs with 4" Suspension Travel
Rough pavement and potholes can shake a trailer to pieces. The MORryde Rubber Suspension Upgrade takes that harsh impact and turns it into smooth motion. Its rubber shear springs soak up road shock and give you up to 4" of suspension travel. That extra movement cushions the trailer and helps everything inside ride steady and quiet.
Less Frame Stress and Chucking: Built-In Lateral Support
Over time, constant bouncing and back-and-forth motion can wear on your trailer frame. This system reduces that stress by adding lateral support through the rubber equalizers and the included X-Factor crossmember. Together they cut down on chucking—the forward-and-back jolt you feel when towing—so the frame stays solid and the ride feels settled.
Heavy-Duty Upgrade for Demanding Loads: Rated for 5,200-7,000-lb Axles
When your trailer carries serious weight, the suspension has to keep up. This kit is designed for triple-axle setups with 33" wheelbases and double-eye leaf springs, rated for 5,200- to 7,000-lb axles. It’s a solid step up from standard equalizers, giving you stronger parts that hold up mile after mile under heavy loads.
Simple Bolt-On Design: Install and Go
You don’t need a full shop to get this upgrade in place. The kit bolts directly on, with hardware included for mounting the crossmember and equalizers. That straightforward setup means you can get the suspension dialed in and ready to roll without complicated fabrication work.
Built to Last: 3-Year or 70,000-Mile Warranty
Durability matters when you spend long hours on the road. The MORryde system is backed by a 3-year (or 70,000-mile) warranty, so you can tow with confidence knowing it’s made to perform and stay strong through years of travel.

Morryde 4000 equalizers and X factor crossmember went on in a couple of hours in my driveway. Liked the function of the crossmember so much I ordered one for the front and rear hangers as well. Notable difference in how contents rode on test drive, no open drawers like usual....

One of the equalizers (SRE4000) failed after less than 500 miles. Had to go through MorRyde and they sent me replacements and stated that the SRE4000 has been replaced by AllTrek4000 (which is the replacements they sent. They are also cheaper than what I bought but they would not refund the difference or the labor I had to pay to the the SRE4000’s installed. I ended up installing the AllTrek 4000’s in the campground while I was on vacation due to the failure.

I feel so much more confident the suspension will hold up to many miles of travel. I love that I can grease the bronze bushings and know that there is maximum protection in those joints. Of course I also love the smooth ride and less disruption inside the camper.

Part of MORryde premium suspension kit. All together they work great. If you are careful ….with plenty of jacks ….job can be done by yourself.

Improved the ride of my trailer tremendously!! Stuff is where I put it when I arrive. Was hoping for a lift out of it but got less than 1/2”. The ride quality is enough for 5 stars. Very little chucking now.

Our middle leaf hanger was starting to bend. We bent it. Ack the best we could, welded a couple supports on the frame and installed this to help keep the hanger from bending in again. Was a nice kit that allowed us to upgrade the equalizers while we were at it. Pretty simple install but we did have a little trouble getting the two crossmember pieces to line up just because the one hanger was still a little bent. We were able to get it straightened out and got it all bolted together. Like the piece of mind that this will bring

This looks to be a great product and I’m excited to get it installed and take the camper for a test the ride. Unfortunately it will still be winter for awhile here. The equalizer looks like it will really soak up some road bumps with the rubber suspension. And the cross bar will help out with the sway.

The bolt kit arrived promptly, as is almost always the case with etrailer products, which I appreciated. The packaging however was of poor quality. The packaging inside the box had broken open and the bolts and nuts were loose everywhere inside the box. The box had also been damaged and I thought for sure there must be some parts missing. Thankfully, after getting everything sorted out, I could see I had the same number of bolts and nuts, so I thought I must have all the parts. I didn't contact etrailer about the substandard packing because I thought all the parts were there, and after all I don't think the seller has a great deal of responsibility in how the the actual shipper smashes up the shipping boxes. The only thing I was shocked about was that there were no instructions. ZERO. I realize it's a pretty straight forward process, But, a few basic instructions would have been helpful. And, after watching a few [online videos], there are plenty of 'helpful hints' that could have been included in the package. After laying out all the loose pieces and figuring out where everything goes, it's fairly straight forward (watch a few [online videos] first, and I don't recommend the one from Morryde, they edit out a couple critical parts the are a pain in the butt to do). I ordered the bolt upgrade as well as the Morryde SRE-4000 suspension with the cross support bar. The box that came a couple days later with the SRE-4000 and cross bar was in perfect shape, had all the contents, but again ZERO instructions. Watched a couple more [online videos] and figured it out. And just FYI, all the parts did NOT fit my Forest River 2916-G Toyhauler. The small 3" bracket plate that goes behind the trailer bracket that holds the new cross piece support bar is too short for that trailer frame. It's not a huge deal to temporarily put the support bar in place and mark the bracket so you can drill a hole through the bracket and then you can use the supplied parts (basically making the parts fit). So, for me this was a 2 day job (4 hours each day) for a 69 year old man with a bad back, working by himself with 2 floor jacks,4 jacket stands, outdoors on a concrete driveway.

The SRE 4000 equalizers made my Jayco Northpoint camper tow better, more stable with much less bouncing than the old CRE 3000. very happy with the product.

- What AllTrek4000, Sumo Springs, and Leaf Springs do I Need for My 2016 Voltage 4150 5th Wheel?Hello Nathan, I reached out to MorRyde, and they informed me that the SRE4000 has been discontinued and is being replaced by the AllTrek4000. I went out to our warehouse and was able to confirm that the 35" wheelbase # MR77ZR is indeed the AllTrek4000. Unfortunately, I don’t have access to a database that shows what suspension system is installed on specific campers (though it would be pretty sweet if something like that existed), so you'll need to verify your axle spacing. Based on my...
view full answer... - Comparing MORryde CRE3000 and SRE4000 Suspension Enhancement Kits for TrailerHey Vernon, so I like the SRE4000 kit part # MR67ZR over the CRE3000 as it has better cushioning with more travel. The 3000 has 3 inch of travel whereas the 4000 has 4 so it's going to give you a nicer ride quality.
view full answer... - WIll MORryde Rubber Suspension Upgrade for Triple Axle Trailers Fit 2019 Grand Design Momentum 395MHi Michelle; the MORryde Rubber Suspension Upgrade for Triple Axle Trailers # MR77ZR will fit as long as you have 35" axle spacing on your 2019 Grand Design Momentum 395M. If you have 33" you need the # MR67ZR instead. I was able to determine that you have 2-1/4" long shackle straps so if you want to upgrade to heavy duty shackles and wet bolts while you're at it you can use the # MR86ZR.

It will keep your trailer's suspension from buckling when making tight turns or driving on rough roads. I have attached a picture below and linked a couple of review and installation videos so you can better understand the functions of the X-Factor Crossmember.

- Determining Correct MORryde Rubber Suspension Upgrade Kit For 2008 Keystone Raptor W/ Triple AxlesI would be happy to help you determine which MORryde Rubber Suspension Upgrade for Triple Axle Trailers you will need for your 2008 Keystone Raptor Toy Hauler with triple axles. First you will need to verify that the hangers on your trailer are at least 3-1/4" long if the leaf springs are installed on top of your axle, or 4-1/4" tall if the leaf springs are underneath the axle. Next you will need to verify the axle spacing on your trailer. You will measure this from the center of one...
