These rubberized equalizers replace the standard equalizers on your tandem-axle trailer's double-eye leaf spring suspension. The rubber cores absorb road shock and help reduce chucking for a smooth ride. Greasable pivot offers easy lubrication.


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


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


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.

  • 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.

  • 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.

  • 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...

  • 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.

  • 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...

  • Recommended Upgraded Equalizer for Trailer with 7,000 Lb Axles and 5-3/4 Long Equalizers
    The upgraded equalizer kit I recommend for you is the E-Z Flex Heavy Duty Rubber Suspension System part # K71-652-00 which will be an exact fit for the 5-3/4" long equalizers that you have now. The E-Z Flex Heavy Duty Rubber Suspension System are cushioned therefore will improve the ride quality of the trailer which also translates to less stress on other suspension components. I understand the E-Z Flex Heavy Duty Rubber Suspension System says it is rated for use on axles up to 6,000...

  • 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.

  • 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...

  • 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...

  • 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...

  • 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.

  • 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.

  • Recommendations to Improve Suspension System on Keystone Outback 33RL Travel Trailer
    The basic suspension components that come on most travel trailers like your Keystone Outback 33RL and 5th wheels do not address any of the road shock and vibration like a traditional suspension system. I recommend the Dexter E-Z Flex Suspension Kit # K71-652-00 to help your suspension flex properly. 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...
