Looks great and probably very much functional, but I only received one of the equalizers rather than the pair. Emailed etrailer for the second one and waiting on response. Hopefully I get it promptly because I have a time slot budgeted out next weekend to work on this trailer.

UPDATED REVIEW: eTrailer is get me the missing equalizer and they were easy to work with. Appreciate that. These are installed on a horse trailer and it definitely smooths the ride out to almost air ride like. When traversing thru potholes or over speed bumps, the axles articulate like a centipede crawling over and dont even hardly notice the trailer bounce. 5 stars for the ride quality! Unfortunately, durability wise, only 2, maybe 3 stars at best. We sue this trailer on a daily basis and they are already worn out after 6 months, even with them being greaseable. I have been having continuing problems with the wet bolts plugging up see my review on the Lippert wet bolt shackle kit and the pivot bushing wore itself into the equalizer housing. I had to weld and re-bore this hole just to replace the bushing I didnt have time to wait for replacements, the trailer had to get back on the road right away. The bushings in the lower flex arms are worn out as well. I am meticulous on maintenance and have tried everything to help these last but in the end, spending $450+ every 6 months to keep replacing these is not sustainable. The root cause I believe to this problem is the leverage the axles have on upper pivot when making turns. I do not know how to avoid this as it is simply a matter of where the shackles are mounted in relation to where the pivot is. I will probably be looking at an air ride conversion ultimately, but in the meantime, I will be ordering another set of these along with the wet bolts and see how long I can make it.

@ChadC What is the capacity of your axles?

Chad C.

@Mike L - they are 7000 lb axles. Trailer is rarely over 10k lbs gross loaded.

Very easy to assemble



by:

We went on a cross country trip right after I installed the new equalizers and I will say that the towing was smoother, softer with less jarring especially over RR tracks and uneven bumpy pavement.



by:

As much as I paid for these, the mounting hardware should have been included instead of having to order a hardware kit costing an extra $XXX. If I didn’t need these so bad I’d return them.



by:

Direct replacement for existing Equa Flex suspension component. The original didn’t last long (5000 miles) but a replacement with the greasable pivots and replacement to beefier stock linkages should help. Time will tell. Installation easy enough - did it at the RV park with some wood blocks, 8 ton jack and hand tools. Not an excellent review because I’m a bit disappointed the original didn’t last long.



by:

Wow! Trailer rides a lot smoother, between new leaf springs and the new equalizers the trailer rides better than it did when new.



by:

Went together like it was supposed to, step up from previous equals flex equalizers.

    The difference between the Equa-Flex Cushioned Equalizers # LC145546 and the Equa-Flex Cushioned Equalizers # LC279688 is that # LC145546 can also work with 5K axles and has a greaseable pivot for easy lubrication, whereas # LC279688 can only work with 6K - 8K axles and does not have a greaseable pivot. Also, the Equa-Flex Cushioned Equalizers # LC145546 does include the 4 wet bolts and flange nuts for install.

  • Option to Replace Equa-Flex Equalizers on Grand Design Reflection
    I could not find any reference to part 435251, though we can help you find the correct replacement for the Equa-Flex on your Grand Design Reflection. To find the right one you need to measure your equalizer from center hole to center hole horizontally and its height from the middle center hole to the top hole. For example, the Road Armor Shock Absorbing Equalizer Kit # LC696740 is 6" from center to center of its bolt holes, and 3-1/4" tall. Then the Equa-Flex Cushioned Equalizers # LC145546...

  • How to Determine Correct Equalizer Upgrade Kit
    I believe you are asking about an equalizer upgrade kit, and we have no way of knowing what is on a 2003 Sunnybrook but can tell you how to determine it. What you need to do is simply measure from center to center of the bolt holes horizontally, and from the center of the equalizer to the center of the top bolt hole; you'll also need to know your axle's weight capacity. For example, if your equalizers measured 7-1/2" from bolt hole to bolt hole and 4" from center of the equalizer to the...

  • Replacement Equalizers and Wet Bolts for Crossroads Elevation 4012
    The Equa-Flex Cushioned Equalizers are not repairable so they will need to be replaced entirely. That said, you have an older model so the new ones will be a nice upgrade. The correct replacement is the part # LC145546. The correct wet bolt kit is the Lippert Tandem Axle Equa-Flex AP Kit part # LC64FR.

  • What is Difference Between Equa Flex LC145546 and Dexter EZ Flex K71-652-00
    The big difference between the Equa Flex equalizer # LC145546 and the Dexter EZ Flex part # K71-652-00 is the dimensions as they basically provide the same cushioning. The EZ Flex has a distance between the mounting holes of 5-5/8 inch and the Equa Flex has 7-1/4 inches for that dimension.

  • Which Equa-Flex Equalizer Fits as Replacement for TREQE1
    Since the TREQE1 is 7-1/2 inches between bolt hole centers from left to right the correct Equa Flex equalizer is the part # LC145546. The part # LC279687 wouldn't be quite long enough.

  • Choosing Between Lippert Equa-Flex Or Roadmaster Comfort Ride For 2018 Grand Design Momentum 351M
    Personally Russ, if you are planning to keep your 2018 Grand Design Momentum 351M toy hauler and want to benefit from a better ride then upgrading to the Roadmaster Comfort Ride Leaf Spring Suspension Kit # RM-2460-2570 makes the most sense. If you choose to keep the Equa-Flex # LC145546 system you can go with the heavier springs but just know that it will likely wear the equalizer even faster since the springs will not flex as much under the weight. This means the Equa-Flex will actually...

  • Recommended Equalizer Upgrade For A 5,200 Pound Axle On A Horse Trailer
    With your axles having a 33 inch wheel base and 5,200 pounds of capacity, we definitely have a couple options available. Both of these options will definitely work with your 33 inch wheel base and can be used with 5,200 pound axles. The first will be the Lippert Equa-Flex Cushioned Equalizers - Double Eye Springs - Tandem Axle - 5K to 8K - Greasable Pivot # LC145546. This will match your 4 inch height, but will be a bit longer at 7-1/2 inches. This shouldn't be an issue, but it may end...

  • Can Rubber Cores On Equa-Flex Cushioned Equalizers Be Replaced
    The Equa-Flex Cushioned Equalizers # LC145546 are not designed to be rebuilt, and replacement rubber cores are unavailable. Although it is a less than ideal solution, if the rubber cores wear out the only choice is total replacement with a new # LC145546.

  • How to Determine Correct Equa-Flex Cushioned Equalizers for 5,200 lb Tandem Axles
    So I can help you determine which are the correct cushioned Equa-Flex cushioned equalizers are for your 2019 Vanleigh Pinecrest, though this will require you to take a measurement. The reason for that is because there is no such thing as a list of replacement parts or parts that fit specific years, makes and models of trailers - there are just way too many trailers. But it is still an easy thing to determine with a simple ruler, since you already have the important information in that...

  • Replacement Suspension Components For a 2015 Keystone Carbon 327 5TH Wheel Toy Hauler
    I do see your 2015 Keystone Carbon 327 5th wheel toy hauler comes equipped with 7,000lb axles. I recommend going with the AllTrek 4000 Equalizers # MR29DR since you are replacing your suspension components. This is a superior equalizer to the Equa-flex # LC145546 style you are using. You should also add either the MORryde X-Factor Crossmember # MR33WR or Drop Crossmember # MR84AR if you have any sewer or other components that interfere with the standard crossmember. This will provide more...

  • What Axle Capacities Does Equa-Flex Cushioned Equalizers # LC145546 Work On
    The Equa-Flex Cushioned Equalizers # LC145546 that you referenced is a kit of two equalizers. These are rated for use on axles with capacities between 5,000 lbs and 8,000 lbs. So since your 15k trailer would most likely have a pair of 8k axles this kit would work great at smoothing out your ride quality as well as being properly weight rated.

  • Replacement Shackles and Equalizers for a 2015 American Auto Hauler w/ 5,200 lbs Axles
    I wasn't able to find any specific information on your 2015 AML Auto Hauler open trailer with tandem 5,200 lbs axles current suspensions. There isn't a database I can look at and tell you exactly what part number you will need. The Lippert Tandem Axle Equa-Flex AP Kit - Wet Bolts - 3-1/8" Long Shackles item # LC64FR are a great option and work with 3,000 lbs - 8,000 lbs equalizers. If you're going to replace the rusty old shackles you should go ahead and put in new equalizers. You will...

  • 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...

  • Comparing Lippert Equa-Flex Cushioned Equalizers # LC279688 and # LC145546
    The Equa-Flex Cushioned Equalizers # LC145546 that includes the 4 wet bolts has greaseable pivot points. This means you can replace the lower bolts that hold the pivot arms in place and replace them with the 4 wet bolts. This kit is rated for 5,000lb to 8,000lb trailer applications. The Equa-Flex Cushioned Equalizers # LC279688 does not have greaseable pivot points and is rated for 6,000lb to 8,000lb trailer applications. Beyond those differences these are the same size with a 4" bolt...

  • What Is The Correct Wet Bolt Replacement For The Equa-Flex Trailer Suspension?
    The Wet Equalizer Bolt with Locknut and Grease Zerk # 126B2 and Bronze Bushing # D014-077-00 can be used to replace the wet bolts that are frozen on your 2020 Grand Design Momentum 351M. The wet bolts on the Momentum were most likely not serviced properly from the dealer/owner of the camper is my guess. If water got into the bushings and caused rust to develop this is what I feel may be causing you to not be able to install grease into the bolt. Typically the grease zerk will be the first...
