Eibach Load Leveling System (aka height adjustable rear)
- Thread starter Ryan at Eibach
- Start date
thanks for the thorough
I installed these yesterday...With the 250 lb spring set. Could not agree more about the upper mount bolt!...pain in the a$$. Finally taped the nut and washer to my 19mm wrench. Took 45 minutes to figure it out on one side, 45 seconds on the other once I had figured out the trick.
Very similar ride on the non KDSS '19 TRD PRO. Also was able to level out the weight of a full tank of gas...both sides are within about 1/8 inch...passenger side ever so slightly higher. This is a great product! Simple and Effective! $$$ Well spent!!

Ryan, do you have these in stock? How about the pro lift springs for the 19 and up Fox shocks?

Adjustable kits in stock.
No PRO springs yet. We’ve temporarily shut production down so they will be delayed.
I went to website and it says to call. When will the option be placed on the website for add to cart?
I installed the kit last week not knowing you guys had this in the works and is now ready to sell.

Anyone running this adjustable rear setup yet that can provide a review? Trying to decide what Rear spring to combine with the TRDP eibach 1.6” lift springs when they finally come out.

X2 on the review. I had the 1" springs on my 19 and they gave awesome ride and less body roll! I'm wanting to know if these sacrifice ride and performance due to the space taken up by the adjuster??
In fact, no they do not. I believe there is a small but noticeable improvement in ride. (I am using them with the PRO FOX shocks...YMMV).
I have the 250-400 LB spring set. Remember, the 3 spring choices are made especially for the adjustable set. You cannot use the stock or any other brand spring with the adjuster set, EXCEPT the Eibach racing springs. These spring choices are ground to fit the adjuster and the new included upper mount.
They are on my DD and I am very pleased with the ride and handling. I just used this set to haul a 1300 LB "repurposed" car hauler with a couple of motorcycles total weight about 2400 pounds. While the truck had to stay in 4th to maintain 65 mph on the freeway, the spring set handled the 190lb tongue weight with no issues at all. No sway, no harshness over pavement dips and /or expansion joints. Barely knew the trailer was back there.
The truck is sitting level in the rear at 23.50 inches, hub center to fender, with about 2.0 inches of adjustment still left to use.
I can't say enough good things about this set from Eibach. Money well spent

Any off-roading/rock crawling with them yet? I like the adjustable height function to deal with my driver side sag plus I can dial in the perfect rake, but I dont want to sacrifice off-road capabilities vs simply using a taller coil. I never trailer anything and don’t have much added weight. Just sliders and full skids incl steel gas tank skid.
Minimum lift at zero load for 300 lb kit?
So can Mark or someone tell me what would the lift be for the 300 lb system at the minimum setting with zero load weight?

Ryan, Can we buy just the bump stop? For us who already have a lift setup but want your better rear bump stop.
Thanks.
Toda, Ryan no longer works for Eibach. I have been told that Eibach includes that specific bump stop ONLY with the Adjustable Rear Set.
Despite the fact that there is clearly a market for them by themselves..

Well that sucks... Thanks for the response.

Eibach Load-Leveling System
Suspension That Grows with Your Build
Text and Images by Ryan Gibbons
While some would argue adding a lift and bigger tires are the way to get a build started, it all depends on what you’re looking to get out of your rig. If you’re going for a true rock crawler, an overlander or just looking to add flare, where you start can vary significantly. Over the course of a build, it’s not uncommon to go back a step or two or change something out for a second time. You can have the best plan in the world for your build but when a really great product hits the market, you might have to deviate from that plan a bit. Or, your build plan changes and you’re wanting more out of your vehicle. It goes without saying, all of this can be costly and return policies on used equipment are virtually nonexistent!
On our 5th generation 4Runner, we’re now at that stage in the build where we need to go back to the drawing board with the suspension. Initially, we went with Dobinsons comfort-rated springs in the front and a 250lb load rating with the rear springs. What was once planned to just be a camping/fire road vehicle morphed into an overland build. Significant weight was added to both the front and rear with steel bumpers, a winch, rock sliders, a steel drawer system, recovery accessories and on occasion, a rooftop tent.
So, our current suspension setup just wasn’t cutting it anymore and the ride was becoming less comfortable by the day. In search of a new rear setup (since that’s where a bulk of the weight was added), we stumbled upon Eibach’s new Load-Leveling System. Designed for Toyota’s with a solid-axle coil spring suspension, the Load-Leveling System offers three different load ratings with varying heights depending on the weight:
• 0lbs to 200lbs (2.0” to 1.5”)
• 200lbs to 400lbs (2.5” to 2.0”)
• 400lbs to 500lbs (2.5” to 2.25”)
The interesting thing about this particular kit is that Eibach leverages their standard 3.57”ID Off-Road Race Springs and an adjustable perch; this allows the height to be raised or lowered depending on the weigh and your desired height. So as your build changes over time, the suspension can truly grow with your build without it taking a toll on your wallet or having to change the build plan. Even more important to us was how adaptable the kit itself is. Changing out the springs can be a straight-forward DIY task with a set of spring compressors. Each kit comes with your desired load capacities springs, two progressive polyurethane bump stops, billet aluminum threaded spring seats, polyurethane spring seat isolators, all the necessary hardware and two 6mm height adjustment tools.
To start, we picked up the 250lbs/in Load-Leveling System and another set of 300lbs/in springs. The springs themselves are reasonably priced, easy to swap out and fairly easy to resell (since they’re common springs). Because our 4Runner can have varying weight swings depending on the setup we’re running, we figured we’d test both out to get our sagging rear-end back to the desired 2.5” lift and comfort level.
Installation of the Load-Leveling System is fairly straight forward and can be done in a few hours with common automotive tools, a floor jack, jack stands, a screw or pole jack, and a little elbow grease. We opted to use spring compressors vs. temporarily uninstalling the rear shocks, which we’ll explain more below.
Simply start by raising the vehicle. Be sure it’s supported with the appropriate safety equipment. Since we wanted to capture the installation process and get the best photos possible, we took our 4Runner to a friend’s shop to get it up on a proper lift.
Next, swap out the OEM bump stops for the new progressive polyurethane stops using the M10-1.5 x 30mm L hex screws, the M8-1.25 x 35mm L Hex screws and M8 flat washers. You’ll notice Eibach’s new bump stops are “outboarded” making them far superior to the OEM stops. This will allow you to get more bump travel back.
Once the new bump stops are installed, you can then start removing the existing springs from the rear. Since we weren’t ready to completely swap out the entire suspension (and since our rear shock bushings are a bit seized up at the moment), we decided to use spring compressors to remove the Dobinsons springs. If you don’t have spring compressors or can uninstall the bottom of the rear shocks from the axle, you’ll just need to disconnect the end links from the anti-roll bar and a screw or pole jack to support the opposite side of the axle before doing so. This may make removing your existing springs easier than using spring compressors.
As you remove the springs, the upper isolators should be removed as well. It’s important to note that with the Eibach Load-Leveling System, the new isolators completely replace the OEM pair and will not be used moving forward with this kit.
Once the rear springs were removed, we then installed the spring perch adapter using the included M12-1.75 x 30mm hex screw and M12 washer/nut.
Next, we set the urethane adapter to the spring mount lining it up with the helical rise on the adapter, sat the spring on top and installed the assembly onto the axle sitting the top of the spring into the adapter. If spacing is an issue during this step, you could compress the spring down a bit with the compressors, then remove the compressor with everything in place ensuring the bottom sits properly on the axle and the top slides into the spring adapter.
Once we repeated the process on the passenger side of our 4Runner, we dropped the truck back to the ground to get an idea of where our ride height sat. Given all the weight we had on, we decided to raise the truck again and use the height adjustment tools to raise the rear ride height. We repeated this process one or two times before we were satisfied with the rear ride height. No more sagging for this 4Runner!
As mentioned earlier, we purchased two sets of springs with this kit. The initial set we installed and tested were the 250lbs/in rated springs. These certainly gave the 4Runner a more controlled feel, less body roll and an increased rate of stability. Given all the weight in the rear, we figured switching to the 300lbs/in springs would likely result in a better all-around feel (which was a correct assumption). With the ease of swapping out the springs on this set, we had an even more accurate ride height of 2.5” in the rear and we felt less back slide off the red light and bounce on the trails.
Because of how well this system has performed for us, we’re now considering swapping out the rest of our suspension to Eibach.
The Eibach Load-Leveling System can be used on most 2000+ Toyota’s, including 80 and 100 series Land Cruisers, FJ Cruisers, 3rd through 5th generation 4Runners, and Tacoma’s. When we spoke to Eibach about this particular kit, they told us that they’re working on a promotional program for those who purchased the kit and also want to switch out the rear springs like us. This further hits our point that this kit can grow with you, and Eibach wants to continue to be a part of your evolving build!

Data shows we got an average of 2" at lowest setting with zero load.
YES, YOU CAN NOW!
We saw that and have created a part number for JUST the bump-stop kit.
Part Number: AK31-82-071-BMP
Price: $199
We just added this so you may have to give your vendor the part number for special order. We have plenty in stock at the moment.
