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.

1/24/2024

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



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:

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



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.

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

  • 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.

  • 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.

  • How to Choose Correct Equalizer Upgrade For Heartland RV 5th Wheel
    Sure thing, though we don't have any way of knowing what equalizer is on any one 5th wheel trailer, so to get the correct upgrade for your Heartland RV 5th wheel you'll need to do a wee bit of measuring. It's pretty simple though, as you'll just want to measure from center to center of the bolt hole, and from the center of the equalizer to the center of the top bolt hole. I have added a photo which shows an example of this for the Road Armor Shock Absorbing Equalizer Kit # LC696740. As...

  • Correct Equa-Flex Cushioned Equalizers To Use In Place of Dexter 13-10 Equalizers
    It sounds like you are looking to swap out the Dexter 13-10 Equalizers. If that is the case then you could go with the Equa-Flex Cushioned Equalizers part # LC279687 like you were looking at but to be on the safe side I would install shackle straps that are 1/4" longer than the ones you have now. I have attached a list of options below as well as a review/install on the equalizers. Please note, the weight capacities listed for the equalizers are just a guide not an actual capacity.

  • 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...

  • 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.

    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.

    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.

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.

  • Replacement for Equa-Flex Equalizers on 2017 Northwoods Fox Mountain 235RLS
    I think your measurements are a little off because the equalizer is worn and compressed. What you have there is definitely the Equa-Flex # LC279687. This is going to be the best option for a replacement since it is what came on your trailer. Using this equalizer will ensure that your other suspension components work together properly since it has the same dimensions. There are other options out there, but the dimensions will be different and could throw off other components. Also, you...

  • 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.

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.

  • Are the MORryde Wet Bolts Compatible With Equa-Flex Equalizers on 2018 Momentum 395M?
    Yes, you will be able to use the MORryde Suspension Upgrade Kit # MR86ZR with the Equa-Flex Cushioned Equalizers # LC279689 on your 2018 Grand Design Momentum 395M. I do recommend using the LubriMatic LMX Industrial Strength Grease # L11390 with a Grease Gun # L30416 to fill the wet bolts. I prefer this grease as it is specifically designed to work well in both hot and cold climates. It also will not wash away as easily when driving in wet conditions.

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...

  • Cushioned Equalizer and Lift Kit for 2016 K-Z Durango 286BHD
    For cushioned equalizers you'd want to measure the distance between the left and right bolt holes and we can pick out what you'd need from there. For example if the distance is between 7-1/4 inches and 8-1/4 inches the EZ Flex part # K71-653-00 would work great but if you have something else let me know. This kit comes with wet bolts and brass bushings too so that would be covered as well. Then for a lift kit the Lippert kit part # RR23QX would give you a lift of 2 inches.

You will need to confirm that your current equalizer has bolt hole center spread between 5-1/4" to 6-1/4" on the lower 2 holes. The kit includes new wet bolts that will allow you to add grease...
