When worn factory springs start to sag, stability takes a hit. This 6-leaf double-eye spring restores the strength your setup needs. It’s rated for 7,000-lb axles (3,500 lbs per spring) and measures 24-7/8" from center eye to center eye. Each of the six 3/8" thick steel leaves flexes to absorb road shock while keeping your trailer level and steady under load, mile after mile.
Every bump and dip transfers force through your suspension. The layered steel design allows the spring to flex just enough to smooth out vibration and impact. That means less bounce, less sway, and less wear on your frame and components when driving through uneven or rutted surfaces.
Rust and friction can wear out a suspension fast. This spring is built from sturdy steel and comes with nylon bushings that fit a 9/16" diameter bolt hole. The bushings help reduce metal-on-metal contact so the system runs quieter and parts last longer.
Measuring your old springs is easy—just go center to center of the eyes when unloaded. Because leaf springs flatten and lengthen over time, this 24-7/8" spring is typically the right match when your old one reads around 25-1/4". It mounts to a hanger at one end and connects through shackle straps or an equalizer at the other, fitting standard double-eye suspension hardware already welded to most frames.
Leaf springs wear together. Replacing both sides at the same time keeps ride height even and axle alignment true. That means smoother tracking down the road and less stress on tires, hangers, and shackles—so your trailer rolls straight and solid wherever you take it.

Will take over 30 minutes to install. I don’t care what the you-tube video says.
Perfect fit. Just wish they came with bronze bushings.
Brought trailer back up to factory level, have not towed it yet
The Timbren SES are the easiest installation. I have to let you know about the ride when we hook up and tow our 5th wheel.
Shipped out very quickly.
As always top notch service!
spring were not good within 5000 miles they were hitting the bottom of trailer .carrying same weigh for 10 years i just rebuilt my old springs
Very helpful for everything
Naomi was great to deal with was very sharp about product super friendly got it shipped out quick had it in 2 days thank you
Great upgrade for my 5th wheel! Easy install and amazing customer support. Unfortunately I cannot attest to further use of these as someone crashed into my rv and totalled it. I will say, given the upgrades (including these), the rv suspension helped maintain control while being hit at around 80mph right into the axles. The leaf springs actually took much of the impact and didn't break, which was surprising given the axles all bent.
Great to do business with your company
Replaced all four springs, fit perfect, but broke one after 6 months, two more within the first year. 3 out of 4 broken in the first year. No warranty as they’re considered “consumable”. Bummer.
The parts ordered came without issue and were exactly what I needed to repair my suspension issues. The assistance I received from Sarah was outstanding.
Perfect fit
Excellent service! We were stranded with a broken leafspring, and this product was delivered overnight. Love etrailer!
I am very satisfied with the parts I receive from etrailer. They have ben providing exactly what I need and in a timely manner. The installed parts have performed well. The service they provide when I call is very helpful. I am very satisfied.
These springs are a direct replacement for the OEM springs on my 2018 Bighorn 3575EL. My OEM leaf springs broke after 54,000 miles.
As described, delivery was good right on time as promised. Too bad you can't find a domestic source for this product rather than buy from China.
Easy install watching Yourube video! So far great product!
Excellent replaced the rear axle springs on my Jayco 5th wheel. went together with no problem
etrailer is always great. They have exactly what you need at a fair price and they ship it quickly. Highly recommend them for all of your RV needs

With more then 20000 mile on these springs they are like day 1 great product
Got the right part fast and was able to get back on the road. Thanks etrailer!
A great shout out to E trailer for helping me get my trailer spring shipped so fast and it worked perfectly. I will be using E trailer in the future. And a big shout out to salesperson Austin for following up and making sure everything was shipped and up to my satisfaction.
One year ago we were stranded in the Poconos with three busted leaf springs. After a few shipping snafu’s we received our leaf springs for our 2018 Grand Design Solitude 377MBS.
They are still in great shape and we’ve had zero issues with them!
Would definitely recommend!
