  • Selecting The Correct Cushioned Equalizer and Wet Bolt Kit For a Grand Design 2800BH
    The Lippert Equa-Flex # LC145546 is the closest cushioned equalizer from Lippert to fitting your Grand Design 2800BH. This particular kit is rated for 5K-8K axles. The MORryde CRE3000 # MR27ZR is going to be the best option for your camper. While this is rated for axles up to 8K all of the CRE3000 equalizers carry this same weight capacity. Do understand the different constructions for these equalizers mean while they may look similar they actually operate differently and since the Lippert...

  • Is Correct Track Trailer Alignment and Lift Kit Compatible With MORryde Suspension Upgrade Kit
    If you install the Correct Track Trailer Alignment and Lift Kit # RR23QX it will require longer bolts but MORryde makes a kit specifically for this. To find the right MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track you will need the center to center bolt hole measurement from your current shackle straps. If you have 2-1/4" shackles you need the MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track # MR58ZR. If you have 3-1/8" you need the # MR98ZR...

  • Will MORryde Suspension Upgrade Kit MR98ZR Work With Road Armor Equalizers?
    As long as your trailer has the Correct Track and 3-1/8" long shackles measured center to center of the holes the MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track - 3-1/8" Shackle Straps # MR98ZR will work just fine with your Road Armor Equalizers. If you have Correct Track but have short shackles you will need the # MR58ZR with 2-1/4" shackles instead. Now if your trailer does not have the Correct Track you will need either # MR76ZR if you have 3-1/8" shackles...

  • What Size Shackle Straps Do I Need for a 2022 Grand Design Imagine XLS 17MKE Travel Trailer?
    Yeah I wouldn't trust AI on that one. The easiest way to determine what size shackle straps you need is going to be to measure yours. The shackles on the MORryde item # MR58ZR measure 2-1/4" long and the shackles with item # MR98ZR are 3-1/8" long. You'll want to measure from center to center of the bolt holes as shown in the included diagram. Which ever one is closest to what you currently have is what you will want to go with. How did you decide on the MORryde Shock Absorbing Suspension...

  • Recommended Shock Dampening Equalizers for a Tandem Axle Trailer w/ 6-1/8" Wide Equalizers
    Hey Pat, thanks for the information! To upgrade your current equalizers to ones that dampen road shock, I recommend the MORryde Rubber Equalizers for Tandem Axle Trailers item # MR87ZR. They measure 6-1/2" from bolt hole to bolt hole and are 3-1/4". They're a bit shorter but that won't negatively affect the movement or height of your suspension. These cushioned equalizers will help to extend the life of your suspension components by absorbing the harsh road shock and reducing back and...

  • 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.

  • Lippert Road Armor Equalizer and MORryde Shackle Strap Replacement Kits
    Hey Dan, thanks for reaching out! The Road Armor Kit # LC696740 is a great upgrade to your current equalizer system, but I do recommend referencing the attached dimensional photo to make sure it lines up well with what you already have. When it comes to the shackle strap kits, you'll want the MORryde # MR46ZR which replaces a standard system. The other MORryde kit, part # MR58ZR, is designed to work with a suspension system using the Correct Track system, which according to your photos,...

  • Can MORryde Cushioned Equalizers Replace TREQ104 in 2020 Winnebago Trailer 2401RG
    Hey Dennis, yes the MORryde CRE3000 part # MR87ZR that you referenced will replace the # TREQ104 equalizers you have now as the dimensions are close enough. I would recommend going with a slightly shorter shackle strap to help offset the dimensional differences though. How long are your current shackles? We have the shorter length available with the part # MR58ZR which are 2-1/4 inches long.

  • Can Both MORryde Suspension Upgrade Kit Shackle Strap Lengths Be Used With MORryde 3000
    Hi Hallzy; the # MR46ZR and # MR76ZR can both be used with the MORryde 3000. The 3-1/8" might get you a little height but at the cost of potentially throwing off your suspension geometry like I mentioned before. If you want to risk throwing off other components and adding increased wear that is up to you but I still recommend adding taller hangers. If you really don't want to cut off and weld on taller hangers you can use the Correct Track # RR23QX which will raise the trailer 1-1/4"...

  • Recommended Equalizer for a 45" Wide Wheelbase
    Hey Mike! I am sure we have an equalizer that will work. It's easier to find a replacement set if you match up the dimensions of your current equalizers. We have the MORryde 14-3/4" Shock Absorbing Equalizers for Tandem Axle Trailers item # MR34AR, that measures 14-3/4" center on center from the outer shackle bolt holes. It is 3-1/4" tall from the shackle bolt hole to hanger bolt hole as shown in the picture below. If you could get me the same measurements off of your current equalizers,...

  • Which MORryde Cushioned Equalizer Fits Freedom Express 248RBS
    Hey Alan, the two MORryde part numbers you mentioned are correct for your Freedom Express 248RBS. For your 42 inch wheelbase you would need the part # MR34AR for the correct size cushioned equalizer and then the heavy duty shackle kit part # MR58ZR is also the correct kit for that as well. At this time there isn't a Road Armor version of cushioned equalizer that matches what you need but these MORryde equalizers will work great so that would be what I would recommend. Is your ride quality...

To replace the bearings in your 2023 Grand Design with Dexter 7,000 lbs axles you will need the following parts: Inner Bearing - Replacement Trailer Hub Bearing item # 25580 Outer Bearing - Replacement Trailer Hub Bearing item # 14125A These part numbers are for the individual replacement bearings.

  • 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...

  • Lift Kit and Wet Bolt Kit for 2019 Dutchmen Voltage 3815
    We do have what you're looking for, but some more information will be required to find the right parts. If your leaf springs run under your axle you can use a flip kit for a lift. Based on your GVWR I'm assuming you have 6,000 - 7,200 lb axles which would have a 3" diameter. If that is the case, you can use the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00. This will raise your trailer by the diameter of the axle plus the height of the leaf spring stack. If your leaf springs...

  • Selecting the Equa-Flex Cushioned Equalizers For a Forest River Cherokee Artic Wolf 23MLE 5TH Wheel
    You will want to use the Equa-Flex Cushioned Equalizers # LC279687 on your Forest River Cherokee Artic Wolf 23MLE 5th wheel. These equalizers are much closer to your 6-1/8" spread at 5-1/2". They are also designed for the lighter axles you have under your 5th wheel since they were designed for axles with individual capacities ranging from 3,000-6,000lbs. The Equalizers # LC279688 you found are not going to work correctly as the 7-1/2" bolt centers are much more than the difference above...

  • Recommended MoRryde Equalizer and Replacement Shackles for a 2023 CrossRoads Sunset Trailer
    Thanks for the measurements and additional information! To determine which MORryde Equalizer you need you'll want to measure the distance at the bottom of your current equalizers from the center to the center of the bolt holes. The MORryde item # MR87ZR measures 6-1/2" and is for 33" wheelbases. The MORryde item # MR27ZR measures 8" and is for 35" wheelbases. I have linked a couple of diagrams below.

  • Can I Use MORryde Suspension Bolt Kit with Road Armor Equalizers?
    You can definitely use the MORryde suspension bolts if that's what you're wanting to use. The correct kit depends on what your trailer is currently equipped with and how long your shackle straps are (see attached photo of where to measure). If you have the Road Armor and Correct Track 2-1/4" Shackle Straps - # MR58ZR 3-1/8" Shackle Straps - # MR98ZR If you only have the Road Armor 2-1/4" Shackle Straps - # MR46ZR 3-1/8" Shackle Straps - # MR76ZR We always recommend when you do something...

  • How Many MORryde X-Factor Crossmember Supports Are Needed For A Tandem Axle Trailer?
    The MORryde X-Factor Crossmember for CRE, SRE, or Stock Leaf Spring Suspension # MR33WR includes one adjustable crossmember. Your existing hardware will be too short due to the extra thickness of the crossmember, so you will need to add # MR58ZR if your current shackles are 2-1/4" long, or # MR98ZR if your current shackles are 3-1/8" long. This will install to the leaf spring hangers, located in-between the front and rear axle. So, for full support, a tandem axle trailer will utilize 3.

  • Troubleshooting Lower Suspension Height On a 371 Fuzion 5TH Wheel Toy Hauler With MORryde CRE3000
    It is normal for the rubber to push out of your MORryde Shock Absorbing Suspension Equalizers # MR27ZR the way it is. The main issue I see is your Shackle Strap # TRSL313 is wearing out. I can see a bit of the hole on the top left strap which means the holes in the strap are being elongated. I recommend replacing these immediately with one of the following kits.

    The correct wet bolt/ shackle upgrade kit for your MORryde CRE/3000 axle will depend on the length of your current shackle links, measured center hole to center hole. For 2-1/4 inch shackle links, use # MR46ZR or for 3-1/8 inch shackle links, use # MR76ZR. If your suspension uses the Correct Track alignment/lift kit, use # MR58ZR for 2-1/4 inch links or # MR98ZR for 3-1/8 inch shackle links.

You don't have to have sides of the axle off of the ground at the same time. Since you're swapping out equalizers you will want to change your shackles too.
