Best 2016 GMC Sierra 3500 Trailer Suspension Parts

All parts fit my rebuild of new springs for my 1999 Bear trailer that my G3 Bassboat sat on for 26 yrs(used a lot for fishing on weekends)

Direct replacement, good quality

New suspension parts made a real difference in trailer handling. Original shackles holes were severely elongated, spring eye mounts were also needing attention. Thank you, etrailer for the needed parts and support.

These parts were a perfect replacement for my old rusted u bolts. I would recommend buying flat and lock washers to place on the u bolts under the nuts due to the holes in the plates being big enough that the nuts get a little torn up when you tighten them, also the nuts it came with aren't lock nuts.

Great product. Probably the best out of all the equalizers as they are cast steel and not welded leaving weak points. Couple of the zerks were non functionable and had to be replaced. Not a big deal. Be careful if you have support V gussets in you spring hangers. The zerks may interfere with gussets. Overall a quality product and a quieter ride providing some cushion from road shock.

etrailer support staff gets 5 stars. However... The kit I received was incomplete. Bushings were missing, two shackle links and a shackle link assembly were missing. Additionally, one of the shackle link assemblies would not accept its' mating link - the bolt shafts were spread apart. one of the equalizer assemblies did not have that gold anodize coating, another had incomplete anodize coating. see pic. etrailer staff shipped me the bushings and the shackle link assemblies to complete my project. As for the finish, POR 15 gloss black is a lovely color. The issue here is with Dexter, not etrailer

By far the best upgrade to our 5th wheel RV. It pulls and rides like a dream now.

Ridiculous... I spent all that time and money. Cracking my head on the bottom of my fifth wheel while crawling around underneath it. I said ridiculous because when I took it for a test drive, it exceeded my expectations! Worth every penny and the headaches! It feels just as if I have a heavy load in the back of my pickup. There is no bucking and the only bumps I feel are what is under my truck tires. Couldn't even feel rumble strips in the road when coming up to a stop sign. I told my wife that I will not own a double axle trailer without a comfort ride system again!

Looking forward to season opener trip! Not that many miles on TT, and am shocked at condition of original plastic bearings. Image shows worst 3 of the 8 removed. The other 6 I didn't drive out of the triangular pieces. Admittedly, I'm retired and not in a hurry but took a total of 7 hours to install both sides including break for lunch and total clean-up of tools. Not a difficult install if you have basic mechanical skills.

After installing the Dexter easy flex and traveling around 7K mile. We are well pleased with the performance. I would recommend the product.

This product did exactly what we needed it to. Bought a replacement axle from Dexter but it created clearance issues in the wheel wells. After installing this kit we have much more clearance and the trailer rides like a dream.

Outstanding product. I am so grateful the install video was added to the page. I am a hands on individual and struggle reading directions with numerous steps at times and it made it so much easier to install this. The explanation of how the mount has to sit flush with the axle seat once you tighten down the spacers was very helpful during the alignment stage. I still have to weld the brackets to the axle for extra support as recommended but I did notice that I will be gaining roughly 4” of clearance height to my trailer. This will allow me to sit more evenly with my lifted truck and get my trailer in my driveway easier since I have a water drainage built in to the entrance way with a big dip.

Exactly what I needed, such an easy upgrade with new heavier springs and the wet bolt upgrade kit. etrailer techs helped answer some questions to be sure I got exactly what I needed.

Replaced 50 year old u Bolts on my horse trailer. Fit like a glove, no issues with install and everything fit as it should.

I bought these as spare hardware to keep with my trailer. They appear to be manufactured well and will be a direct replacement if I have a failure while transporting.

Delivery was faster than expected and well package in the follow up was great. Thank you, E trailer same great service as before your eternal customer.

The holes to mount to top of axle fit fine. It's the holes the mount on the side, to the frame bracket are filled too low. They're off by half a diameter.

I purchased this item for 2015 micro mini with torsion axles.Simply put, the suspension lift for this trailer is no longer available.Three of the holes lined up perfectly.The 2 bottom holes and the one front one that bolts to the trailer. With an angle grinder, I cut the button rail of the lift kit with an angle gri der and had to drill the top hole of the bracket on the trailer to install the fourth screw and torque all bolts. It fits and operates perfectly and my minor mini went from 6 inches of ground clearance to 9 inches of clearance at the lowest part of the trailer. A beautiful retro fit for an item that is no longer available for purchase anywhere!!! If.your handy with an and grinder this modification is possible with this kit and well worth it!!! Sorry no photos as of yet.

We purchased these parts for a custom build trailer for hauling heavy tool boxes over steep grades. Since completion of the build about a year ago, we have been using it and put a lot of miles on it. The hydraulic surge brake system makes it worry free. We can tow it behind different vehicles of differing weights and wheel bases and not worry about setting trailer braking, it is very nice. We will continue to use etrailer for our trailer needs.

Could you please share some info as to what is the hanger spacing measurements for the APT8 kit with 25-1/4" eye to eye springs? I've tried researching it but no luck. Would really like to get this welded on this weekend Thanks

I love this suspension its quiet and the handling and ride is the best I have ever used on a trailer. Gonna buy another set for my gooseneck trailer. Will never go back to leaf springs!

I used these to replace the leaf springs and equalizers on a 20’ gooseneck cattle trailer that I rebuilt. The ride is great and the usual rattling and clanging of the trailer going down the gravel road is gone. So far I am very happy with the ease of installation and the performance of the suspension. I guess only time will tell about the durability of the rubber components in the long run.

Sumo springs work great. I was a little skeptical if they would work since the Dexter 5100 lb axles on my trailer have two ribs going across them, I'm assuming for strength. The sumo spring bracket was just wide enough to sit on top of the rib center point. The bracket could be 1/2" wider, it would help. I tapped the bracket in and torqued it. As you can see it didn't go in all the way but seems to be ok. Took a road trip, highway, gravel and a rough forest road. Checked the torque after the trip and nothing moved. Sumo springs helped with the trailer sway and should take some load off the springs and shackles. I am pleased so far with this product.

Been great so far..fabbed removable axle system with the timbrens

Seems like a great product and service was excellent. UPS lost one of the three parts and was a week long in delivering it, and then said that it was because it was packaged poorly from etrailer. I used a 4x6 steel rectangular tube spacer to get my trailer back up to the original height. Seemed pretty straight forward, but it would be nice if the system could be designed so the user doesn't have to cut the mounting brackets off the axle and re-attach the Timbren brackets.

these work to replace the plastic bushings in the leaf springs. nothing fancy, they work as they should, easy to install.

Correct part to replace the junk/garbage plastic bushings from factory that wear out in about 4 miles. Use with wet bolts, great upgrade

Just what I was looking for to add another 1 or 2 leaf spring to the springs on the truck. Great service, fast shipping. great company to do business with.

Part worked awesome and was the perfect fit thank yall for the support.

Just what I needed. Fast delivery and easy to install. Adam did a great job finding this part for a older trailer.

I have a 2001 travel trailer and I had a spring break on the front axle, thank God I was only a quarter mile from home. I went on the E trailer site easily found the springs I needed, the Triangular equalizer, and the bolts I needed. My order arrived 3 days later, I was very pleased with the quality of all my parts. Some reviews complain about the parts made in china, well lets be honest what is made in the USA any more. Every thing fit as expected and my project is done. Would definitely recommend E trailer to anyone who wants a good product at a fair price . Thanx E trailer!!

fast shipping, cheapest price. what more could you ask for? For it to work perfectly! well of course etrailer only sells great quality products. again thank you for always having what I need to keep my tilt deck on the road!!!!

part came just as described and exactly what i needed. thank you

Less bouncing, furniture doesn't move around when traveling on rough roads, better stability.

Great product! Excellent installation instructions (for the DIYer inclined to step up!). Excellent support... I ordered the wrong kit (my axle size was different) but customer service worked with me to correct it. I installed the shocks incorrectly but the service team quickly pointed out that I misread the instructions. I have a 12,000 pound, 38' trailer with a lift on the back for my 900 pound motorcycle. I've put around 7500 miles on it including a couple times across the Rockies and absolutely love the handling. Self installation is not for the feint of heart but it saved me around $10k labor not having a dealer install it.

These fit perfectly on my triple axle Kaufman trailer where I replaced all 4 of them. I got some commercial quality spray paint and painted them black. I'll also include some pictures of my old ones that were original with the trailer. You can see they definitely needed to be replaced! I always use etrailer for my trailer parts. Everything is good quality, fits perfectly, and arrives on time.

Trash !!!! 4 equalizers and just one it’s holding the weld now I’m losing money because my trailer suspension its not functioning

Very good quality and quick delivery

Installed a year ago, I made a drilling template to help locate the frame mounting bracket screw holes. Installed a set on (2) fivers, spent average of 2.5 hours for total installation per fiver. Helped the ride of the trailer. Would certainly recommend the shock kit.
