So far so good, I hate doing reviews right after the install but I will update if things go south. Hint- the shackles do not press tight against the springs. Its obvious why when I thing about it because it needs room to travel. But while tightening the bolts there was a little slop until I figured out why...

The Grade 5 or maybe 3 ?? greaseable bolts have really cheap flange nuts. They easily strip. Grade 8 hardware would be a much better choice for an HD Upgrade kit.

Review from a similar Shackle Upgrade Kit in Trailer Leaf Spring Suspension


This is a very well put together kit. Fairly easy to install. It’s nice that the bolts are already seated into one side of the shackle. I will definitely buy this kit for my other trailers. I highly recommend this kit. Just make sure you grease them once and while.

Review from a similar Shackle Upgrade Kit in Trailer Leaf Spring Suspension


I open box. Plastic is torn away from cardboard and parts are floating in box. No problem Put all parts together and sorted them out book comes with package but no numbers are listed to what your supposed to have. So I got 4 shackles with all the parts one had damaged threads 4 of the same size pins and bushings as shackles. And 2 shorter pins and bushings. Remove from axle old pins and equalizer pins notice pins for front leaf spring and equalizer pin needs to be smaller then shackles pins My kits got 4shackles pins and 2 short pins needs to have 6 of them. The parts I have do look good just disappointed quality of shipment


Comments
Sorry to here about the loose parts and damage. Customer Service will contact you.

  • How To Determine Correct Wet Bolt/Shackle Upgrade Kit For Tandem Axle Trailer
    I can help you figure out how to determine the best option for a wet bolt/shackle upgrade kit, though in order to determine the correct one you will need to take a quick measurement of the shackle straps on your Jayco Jay Flight. The reason for that is these kits aren't specifically designed for any trailer, so to ensure the best fit you want to get the kit with the same length of shackle straps. There are a pair of options for you, depending on the length of your shackle straps: -...

    Thanks for the information! The Equa-Flex 145545 you have is the Equa-Flex Cushioned Equalizers - Double Eye Springs - Tandem Axle - 6K to 8K # LC279688. Since you measured your shackle straps and found they are 3-1/8" center to center of the holes then the MORryde Suspension Upgrade Kit for Tandem Axle Trailers - 3-1/8" Long Shackle Straps # MR76ZR will work perfectly. This kit includes new heavy duty 3-1/8" shackles straps, wet bolts, nuts, and new bronze bushings. I included...

  • My 1971 Ideal Camper Has a Different Leaf Spring On One Wheel and Random Hardware In Suspension
    With the age of your 1971 Ideal 22' Camper I am going to recommend changing out all the suspension components. I happened to notice some of the hardware was also replaced at some time as well and it does not look like they used the correct parts either. For the Leaf Springs you will need to jack up the camper to remove as much weight from the suspension as possible. You will need to measure the spring in a few places to be able to ensure that you find the correct replacements. I have...

  • Shackle, Bushing, and Wet Bolt for Shackle Length of 2-3/4 inches
    We have shackle straps that are 2-3/4 inches in length like the part # CE14103G but this isn't one of the heavy duty kits. For a bronze bushing you'd want the part # D014-077-00. Then for a wet bolt you could use the part # 126B2.

  • Does the Lippert Road Armor Come with Mounting Hardware
    The Lippert Road Armor # LC696740 does not come with the bolts you'll need for installation, so you'll still need the hardware. However, the # LC64FR you're referring to are only 3/8" wet bolts and you'll actually need 9/16" diameter wet bolts. The best solution is going with something like the MORryde Suspension Upgrade Kit for Tandem Axle Trailers # MR46ZR (2-1/4" shackles) # MR76ZR (3-1/8" shackles). These kits come with the bronze bushings, wet bolts and shackle straps. There are some...

If you have different length shackles or have the Correct Track system, there are MORryde upgrade kits that will work, you can see them by clicking the provided link.

    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.

To determine if either the Equa-Flex Cushioned Equalizers # LC279687 or MORryde Rubber Equalizers for Tandem Axle Trailers # MR87ZR will fit your 2019 Heartland Pioneer 250 RL you will need to measure the length of your current equalizers between the two horizontal mounting holes on center.

  • Upgrading To a Shock Absorbing Suspension Equalizer With A 42" Wheelbase Tandem Axle Trailer
    It is a good way to measure for a replacement equalizer, but I always recommend verifying the equalizer length as different springs will allow for different length equalizers. As you have a 42-1/2" spacing you most likely have the 14-3/4" equalizer. This is the measurement from the center of front bolt eyelet to center of rear bolt eyelet on your equalizer. I recommend the MORryde 14-3/4" Shock Absorbing Equalizers for Tandem Axle Trailers w/ 42" Wheelbase # MR34AR. This CRE3000...

  • Can 7-3/4" Dexter EZ Flex Be Replaced By 6" Road Armor Shock Absorbing Equalizer LC696740?
    You are correct. Since the Dexter E-Z Flex Equalizers you have on your 2021 Grand Design Reflection 337RLS measure 7-3/4" on center between the horizontal mounting holes, and the Road Armor Shock Absorbing Equalizer # LC696740 is only 6" as shown in the included diagram, you will need to use longer shackle straps. Since you mentioned your current shackle straps are 2-1/4" the 3-1/8" shackle straps # TRSL313 would be what you need to keep your suspension geometry the same. Another...

  • What Length Heavy Duty MORryde Shackle Kit to Use CRE3000 Equalizer
    If you went with the shorter shackle kit part # MR46ZR you'd slightly increase the ride height of your trailer or if you went with the longer one # MR76ZR you'd lower it ever so slightly but either would work great. Either will work great with the MORryde Equalizer Kit for 42 inch wheelbases part # MR34AR.

  • Will the MORryde Suspension Upgrade Kit for Tandem Axle Trailers Work With Equa-Flex Equalizers
    Yes, the MORryde Suspension Upgrade Kit for Tandem Axle Trailers part # MR76ZR will work with the Equa-Flex Cushioned Equalizers part # LC279687. I would however just retain the bushing already installed in the equalizer. The dimensions of the equalizer from the left and right bolt holes should be within about 1/4" of one another to remain compatible.

  • Will the MORryde Premium Rubber Suspension Kit Replace Equa-Flex System with Correct Track
    The Equa-Flex equalizers # LC279688 are already a cushioned equalizer that's designed to provide an upgrade to a stock suspension and being completely honest, it's rather subjective to say whether the Equa-Flex system is better than the MORryde Premium Rubber Suspension Kit # MR47ZR. With that said, I really like the fact that the MORryde system gives you a cross-member that's attached to the equalizers which acts to help provide some added support to the trailer frame, so it does have...

If the axles measure 33" apart then use part # MR87ZR but if they are 35" apart then use part # MR27ZR. If you want to add shackle straps and wet bolts, part # MR76ZR is for 3-1/8" long and part # MR46ZR is for 2-1/4" long. If you can inform of which LRE system you have I would be glad to inform of which CRE replaces this.

  • Wet Bolt Kit to Use with MORryde CRE3000 Cushioned Equalizer Kit
    The Correct Track setups are basically an alignment/lift kit for trailer suspension that attaches between the hangers and the equalizers. You'd know if you had them or if you had them installed so since you aren't sure what they are I'd assume you don't and instead the wet bolt and shackle kit you'd want is the part # MR76ZR. This will work great with the MORryde Shock Absorbing Equalizers part # MR27ZR as well.

    The lengths of the shackles that come with the equalizer kit part # K71-449-00 that you referenced are 2-7/8 inches measured from hole center to hole center. If yours are currently 3-1/8 inches this change would slightly lower the height of the trailer but it would still work. To match the shackle lengths and also be the thicker style you'd need the kit # MR76ZR with the # K71-655-00 which is cushioned. Or for just a standard equalizer and shackle kit you'd want the # e99ZR.

  • Will Adding the Lippert Road Armor Raise My Trailer to an Unsafe Height
    We've seen a lot of our neighbors raise their trailer considerably more than 1/2" without adversely affecting handling on their trailers; many of them use spacer blocks or axle flip kits to gain as much as 4 to 4-1/2" of additional clearance. As long as your trailer tows level with your truck, I don't believe that extra 1/2" of height will have the negative effects you might expect.

Please note, the above are for models with the Correct Track system. For standard models you'd simply use part # MR46ZR or part # MR76ZR. The shackle straps are measured from the center of each eye.
