Need to raise my deck over trailer deck. Purchased four of the spring seats. Dropped the four shackles, pulled axels out and measured and welded them on opposite the existing ones. Refastened the shackles and installed axels under axels on new sets. Worked great!

No issues with the bearings

Axles flipped, and going down the road.

Perfect fit as described! Uploaded picture for proof. So far i couldent be happier with etrailer.com, great prices and fast shiping. I haven't had an issue with anything so i have no opinion as far as customer service goes. I would definitely recommend to a friend.



by:

The axles that I ordered last year are still working out great. But even better than the parts was the service I got from etrailer. It was so great working with a company who took the time to listen to my project and help me get the right parts I needed, especially coming right off the heels of a terrible experience dealing with bad information and wrong parts from a competitor. Even with some damages in shipping, the returns/ and replacements were no hassle, with most issues being quickly resolved and not even costing me any additional downtime. As a contractor keeping a small fleet rolling, your competency and professionalism have made me a customer for life!! You guys at etrailer will be my first stop for trailer parts.

Received my parts today and after examining everything all looks good.
The quality of parts looks excellent and can't wait to start installing them.
Shipping was fast and arrived as they said.
Great company to buy with.
Will was very helpful and very knowledgeable about parts.
If you call would definitely ask for Will.

just what I needed

Products were as advertised, worked well and installation went as planned. Accomplished task - moved under hung leaf springs to over axle (tandem drop) on older horse trailer, to regain bumper clearance - new truck sits higher than old, also allowed extended goose neck to eliminate tail gate damage, while leveling trailer (nose no longer stuck in air). I would purchase again without hesitation.

Works as expected, Im happy with the product and results- would purchase again if I have a trailer in the future that needs a lift.

Not much to say, they are consistent and fit the axle tube well. Clean welding material.

Thanks

I replaced my leaf springs, drums, brakes and added the Dexter E-Z Suspension kit to my Keystone Cougar Fifth Wheel trailer last year. This was my first time working with etrailer and I can’t say enough about how well it all went from the ordering to the install.
Tammie P did a amazing job with knowing what parts would work best on my trailer. Tammie also gave me updates on my deliveries that I appreciated. I had a trip planned short after I received my parts. So having someone at their end checking on arrival dates helped. In the future I will definitely use etrailer for all my trailer needs. Thanks again for all the help! Great Team....



by:

The parts arrived quickly and were an exact fit, thank you!



by:

I installed a set of these spring mount brackets one year ago and I am glad I purchased it from etrailer. I purchased it on line just to make sure it would work on the 1964 axle that I was going to weld it to in order to complete the install of a new set of springs that I also purchased from etrailer. Everything fit perfectly and etrailer is now my go to for all my trailer needs. George J. was very professional and knew the product(s) would work. And it did!

Thank you George and etrailer.



by:

Great product and great company to work with. I ordered regular shipping and they upgraded me to 3 day shipping an no charge. Very satisfied with the product and company.



by:

Product was exactly as described. Used the info on website for location of mounts. Couldnt be happier.
Awesome customer service as well.



by:

Parts were Exactly what I ordered delivered fast will shop from this company again



by:

The seats were just what I needed Last year I moved the trailer
springs from the bottom of the axel to the top when I did I had
to turn the axel end to end it caused the trailer to wear tires out .
brakes to wear out .I am turning axel back and welding new seats
leaving hubs running right. Back to factory only on top of axel.

Thank You



by:

I used these to flip the axles on my 2005 Weekend Warrior FS3000 30 ft toy hauler. This was by far the best price around and they worked well for my application. I did have to hit them with a grinder to clean up some burrs so they would sit flush but other than that they are great.



by:

I am using two second hand axles for my trailer and the spring seats were in the wrong place. They were hard to find because I didn't know what to call them, but I was really grateful they were available. They will complete the installation of the axles and are sturdy and cut perfectly.



by:

I had ordered some parts online to rebuild the suspension on one of our trailers. Customer service called me a short time later to inform me that they were out of stock on some items, they asked if it was possible to substitute some items. She was able to find the exact parts I needed in a different kit. The parts came within 3 days, very well packed, and they fit perfectly! This is the 3rd time I've ordered from etrailer and they have exceeded my expectations every time. EXCELLENT customer service and quality parts.

  • Do Dexter Axles With 86-1/2 Inch Hub Face Have 71-1/2 Inch Spring Centers
    Each of the 86-1/2 inch axles we offer, such as the 5,200 lb Dexter Trailer Axle w/ Electric Brakes # 8327816-EB and 6,000 lb part # 8327826-EB have 71-1/2 inch spring centers. So what you would have to do is get new spring seats welded on at the correct position, and for that use Spring Seat for Typical 5,200-lb to 7,200-lb, Round Trailer Axles with 3" Diameter # TRSS300.

  • Replacement Axles for 2017 Grand Design Reflection 29RS
    What you're looking for is an 86-1/2" long replacement axle. Since you will need new hubs and drums, along with brakes, I recommend getting the # 8327816-EB. This has a 71-1/2" spring center length so you will also need to cut off the spring seats and weld on # TRSS300 to match the current 68-1/2" measurement. Grand Design does a great job listing their parts, but unfortunately they don't include the leaf spring information. You will need to measure your current leaf springs to find the...

  • Replacement For 86-1/2 Inch Long 5,200 lb Axle
    Appreciate the photo, and what that shows is you have a 5,200 lb axle that is 86-1/2 inches hub face to hub face with a spring center to spring center measurement of 68-1/2 inches. We do have a replacement with that capacity and the correct length, but you'll have to have new spring seats welded on as we don't have one with the spring center measurement. So what you'll need is the following: - Dexter Trailer Axle Beam with E-Z Lube Spindles - 86-1/2" Long - 5,200 lbs # 8327816 - Spring...

  • Can New Spring Seats Be Welded Onto The Top Of An Trailer Axle Beam
    Yes, you'd just need to reach out to a qualified welder and have them weld on spring seats like part # TRSS300 to the top side of the Trailer Axle Beam with Easy Grease Spindles # e45GR. It's super common to do for people who have an underslung setup and want to raise the height of the trailer. When you remove the old axle you'll also want to replace the u-bolts with ones like part # CE23003 since they get stretched when torqued down and shouldn't be reused.

  • Different Size Equalizers on Triple Axle Trailer
    The equalizers on your triple axle setup will not be identical and there is nothing to worry about with your hanger spacing. However, since they appear to be worn it may be a good idea to go ahead and upgrade them. It looks like the Dexter E-Z Flex Suspension Kit - Double-Eye Springs - Triple Axle - 6,000 lbs # K71-656-00 is the closest match to what you have right now. As you can see in the kit, and others like it, there is a difference between the two sets of equalizers. The shorter...

  • Replacement of Lippert 5200lb Axle, Electric Drum Brakes, and Hub and Drum Assembly
    Since time is a factor and we do not have the complete axle brake and hub set up, Item # 8327816-EB, in stock (August 2021). I recommend the Dexter Trailer Axle with E-Z Lube Spindles item # 8327816. This axle is 86-1/2" Long with a 5,200 lbs capacity that will replace your Lippert axle. The TruRyde spring seats item # TRSS300 will work well with these axles. Unless your trailer hubs are brand new you should replace both of them and keep the passenger side one around as a spare.

  • Replacement 3 Inch Diameter Axle Beam with 95 Inch Hub Face Dimension
    An axle with a 3 inch diameter axle tube typically has a 5200, 6000 or 7000 lb capacity. The inner and outer wheel bearings would be the determining factor that would tell you the actual capacity. We do have 95 inch axles (hub face to hub face dimension) but none of our offerings have the proper spring seat spacing, so you'd need to add seats in the correct locations. • For a 95 inch 5200 lb axle with spindles compatible with a 25580 inner/LM67048 outer bearing, use # e55GR • For a 95...

  • Replacement for 5,100 Pound 86-1/2 Inch Long Overslung Dexter Axle
    When choosing a replacement axle you want one that is the same length. Since you have a hub face measurement of 86.51" a better choice would be an 86-1/2" axle. The # e65SR is an 89" axle so it is several inches longer. Also, you don't need a 6k axle, a 5,200 lb axle is fine. You can use a 6k axle but you need to keep in mind that this will not increase the capacity of your trailer. For an axle that is equivalent to the # e65SR I recommend the # e73SR, or if you just need the axle itself...

  • Replacement Option for 5,200 lb Dexter Axle on 2016 Arctic Fox 25R
    We don't have an exact match for all of your measurements but you can use the Dexter Trailer Axle Beam # 8327816 as a replacement. This is 86-1/2" long so it will stick out 1/4" more on either side of your trailer, something you won't even notice. The spring center is also different but that is fairly common when replacing an axle. What you can do is cut off the spring seats and weld on # TRSS300 to match your existing 67-1/24" measurement. Also, unless you're dead set on a Dexter axle...

  • Can 7,000 lb Trailer Axle e35GR Replace 94 Inch Hub Face, 77 Inch Spring Center Axle
    Even though the spring centers are different, since you have the same hub face to hub face measurement of 94 inches, you can replace your Lippert axle with the Trailer Axle Beam with Easy Grease Spindles # e35GR. However, the spring seats do need to be in the same spot, so you'll need to weld on new Spring Seat for Axles with 3" Diameter # TRSS300. The hub face measurement is the most important one as it is common to move the spring seats, so that's all you'd need to do to use the Trailer...

  • Spring Seat for 7k Trailer Axle w/ Electric Brakes # e23SR for Underslung Axle
    We only have the 7k Trailer Axle w/ Electric Brakes # e23SR in an underslung configuration so what you can do is install a different set of spring seats on the opposite side of the axle like with # TRSS300.

  • Replacement Axle For a Grand Design Imagine 2670MK With Higher Weight Capacity
    We have either a 5,200LB # 8327816-EB or 6,000LB # 8327826-EB axle you will be able to use to replace your current 4,400lb axle. Both these axles have the 86-1/2" hub face spread and include hubs with electric brakes and the 6 on 5-1/2" bolt pattern your wheels and tires require. The brakes are the larger 12" diameter but will fit with the ST225/75R15 tires I see the Grand Design Imagine 2670M comes with. You will need to have 2 new Spring Seats # TRSS300 welded to the axle at the 68-1/2"...

    For your 2018 Grand Design Reflection 337RLS you need a 6,000 lb axle with an 86-1/2" hub face measurement and 68-1/2" spring center length. Since the spring seats can be moved, you can use the Trailer Axle Beam with Easy Grease Spindles # e33GR as a replacement. This axle matches your current axle length and has a spring center measurement of 71-1/2". You will need to cut off the spring seats on the # e33GR and weld on # TRSS300 to match your current spring-center-to-spring-center length....

  • Parts Needed to Upgrade from a 2-3/8 Inch Axle to a 3 Inch Axle
    We do have a 3" axle with a 86-1/2" hub face to hub face measurement. It is the Dexter Axle Beam with E-Z Lube Spindles item # 8327816. The spring seats sit at 71-1/2" so you will need to move them. You'll want to replace them with two of the 3" Spring Seats Item # TRSS300 for each axle. We do not have a 2-3/8" axle in your dimensions. You will also need to replace your u-bolts and plates. You will want the U-Bolt Kit for Mounting 3" Round Trailer Axles item # APUBR-9.

    You can definitely use the # e35SR. As you said, you can cut off the spring seats and weld on new ones to match your 78" measurement. This is not a service we offer, but we do have the spring seats # TRSS300 available. Also, swapping out the springs and shackles isn't going to do what you want. The other option would be to flip the axle assuming your leaf springs are currently under the axle. For that you would need the Dexter Trailer Springs Over-Under Conversion Kit # K71-385-00. This...

    The Dexter Trailer Axle Beam with 4" Drop # 8327860 has the 95" hub face to hub face measurement that you are needing. You would need to remove the spring seats from the factory and add 2 new Seats # TRSS300 to the axle in the 78" center position you are needing. This particular axle is rated for 7,000lbs. If you are needing a different weight capacity please let me know.

    Hey John we do have a potential axle option for you. We have axles with the 86.5" hub face, such as the Trailer Axle Beam # e33GR, which is rated for 6,000. This axle has spring seats at 71-1/2", and they are underslung. We are not able to weld on spring seats for you here, but we can sell you a few loose spring seats # TRSS300. You would just have to have them welded to the top of the axle tube in your desired location. This axle is also available in a 5,200 lb capacity # e45GR if that...

The Dexter Trailer Axle Beam with 4" Drop E-Z Lube Spindles - 95" Long - 7,000 lbs item # 8327860 axle you were looking at is what Dexter recommended. There are no available axles with a 77" spring seat. These have a 79-1/4" spring seat and the replacements you will need are Item # TRSS300.

Basically you install the new spring seats on the opposite side of the axle and then move the axles to the other side and secure them with new u-bolts.

    Thanks for the picture! I couldn't get all the information I needed off of the tag but our best option to replace the axle on your Keystone Montana is the Dexter Trailer Axle w/ Electric Brakes item # 8327826-EB. This axle has a 6,000 lbs capacity so depending on your specific model of High Country it should work. It includes electric brakes and hubs with a 6 on 5-1/2 bolt pattern.

We have an option to replace that with a 6,000 lb axle, but the spring centers will be different on the axle we offer so you'll have to have new ones welded on 68-1/2".

Unfortunately, 4,400 lb axles are no longer being made so you will also be replacing the hubs and drums. When choosing a replacement axle you typically want to match the hub face measurement. You will also need a higher capacity axle (5,200 lb) since moving down in capacity wouldn't be enough for your 7,800 lb GVWR. I recommend...

    It sounds like you're looking for the Dexter Trailer Axle Beam part # 8327816 which is 86.5" long at the hub face and has a 5,200 lb weight capacity. The spring seats however will need to be moved in for your application which requires tack welding so bear this in mind, you'll likely want part # TRSS300 to go with as removing the old ones cleanly is difficult. If you're looking to save some cash we do have this same axle through our in-house brand as part # e45GR.
