    Customers say

    Customers like the leveling kit for its ability to keep the rear of the truck level. They say it helps reduce sag and eliminates any sagging in the rear end of the vehicle. They also appreciate the easy installation and stability. However, some customers have reported that the ride quality is a little bumpy and stiff for the first 1,000 miles. Opinions are mixed on softness and value.

    Customers are satisfied with the level of the o rings. They mention that it allows their truck to sit much more level when towing a 10k lbs trailer.

    Simply unbolt your u-bolts from the rears, slide these under, and re-tighten them. Took about 30mins for the install.I have a 2001 Toyota Tundra with an AAL installed in the rear from Wheelers off-road. The ride wasn’t stiff by any means but with the sumo springs, it smoothed out and got a little firmer. No more harsh jarring feeling on bumps.

    5.0 out of 5 stars I'm quite pleased.
    Reviewed in the United States on May 16, 2017
    I waited a bit before writing this review. Initially I did not like these. But now I really like them.

    Installation on my 2016 tacoma was easy. Loosen the u bolts, remove the factory bumpstop, install the sumospring mounting plate, torque the u bolts. I found the torque for the 2016 tacoma rear axle ubolts online. It's 52 ft lbs. I torqued mine to 58. Once bracket is installed then screw down the sumospring to the mounting bracket using the blue loctite included pitting a decent amount on the sumospring mounting screw which is welded to the plate. Many people seem to think that the loctite is for the axle ubolts. But the directions clearly state it's for screwing the sumospring down. Axle ubolts don't need loctite. I rechecked mine at 500 miles and 1000 miles. All good.

    I needed to shift one sumospring slightly back on the spring to get it to line up perfectly with the bumpstop bracket on the passenger side. Easy adjustment.

    Now have about 1000 miles on them. Initially I thought they rode a bit hard. But they seem to wear in. Maybe slightly harder than factory springs on the trd off-road. But I like it. They raise the back of the truck just about 5/8 inch as other states, which is just perfect as the gen3 tacoma has a higher hood so even unloaded it looked low in the back. With a load they are great. No where near as much squat. Best part is when towing my 3000# travel trailer. Trailer has a 330# tongue load. Generator and other gear in the back is about another additional 200#. Before the back end squatted. It was fine before, no bottoming or anything. But headlights were high and it looks stupid with rear end squatted. Now it's perfectly level. Ride is a little stiffer when loaded, but it's good. It is a truck. I hate that toyota has gone out of way to soften ride too much, compromising loading ability.

    So far I really like them. Of all the options these were far by far the easiest. Helper springs seem to have challenges hitting the gas tank or frame. Airbags I've had before. They always seem to leak in the New England salt. This seems to be a great compromise for the person that rides empty much of time but then heads off to Home Depot for a large load or takes off like I do with a travel trailer and another couple hundred lbs in back. I really researched these. On website after website I could not find a single review that said they damaged the truck in any way. Some people did not like the ride. But most people seem to really like them.

    We shall see how they hold up long term. I kept the factory bumpstops just in case. I did think these were just a little bit overpriced for essentially two pieces of engineered foam and a couple brackets. I'd say $150 would be more reasonable. But they seem great in spite of maybe being overpriced.

    Remember to do one side at a time. Loosening both sides at once would be dangerous and could throw off your alignment. And if you are using a lift like I did use a pole jack under the axle to support the axle.

    5.0 out of 5 stars Transformed the handling of my older model 2006 Nissan Frontier truck, tow vehicle
    Reviewed in the United States on June 7, 2021
    I installed these on a 2006 Nissan Frontier in order to improve squat problems with loads in the bed and while towing. I chose them because of the set it and forget it nature of the design.

    I chose them over airbags, and I chose them hoping to get enough towing improvement to avoid needing a weight distribution hitch on the times I pull a +/- 4500lb trailer. I know the tongue weight of my trailer is nearly the same with these installed and that suspension enhancements are not the fix that a WDH would offer. Even so, the support these are providing has improved the way my trailer pulls.

    The results were noticeable the first time I pulled the truck out after finishing the install and the truck feels safer with these on. Bed squat is noticeably improved and the ride quality improved loaded or unloaded. I have less stutter from the rear end. It feels supported, like a hand is gently gripping the back end of the car. It also improved the way the truck feels in turns on mountain roads, lessening body roll. I installed the blue, thinking that my loads in the bed rarely go over 300 lbs and that I'd prefer the softer ride most of the time; If it squats a little for some future max load it's not a big deal to me.

    Previously I'd put on new shocks on this same truck because the old ones were toast. So it was stock suspension plus new shocks that handled loads poorly and adding these mattered more than the shocks.

    5.0 out of 5 stars The good the bad and the ugly!!!
    Reviewed in the United States on May 2, 2023
    2021 Toyota tundra with the blue. This is the softest they make and yet it could be a little softer. I tow a 24ft travel trailer and these are perfect. Before the back of the truck would bounce even with bilstein shocks, the good, but now it rides smooth with out the bouncing. Also helps with steering. The bad is thier not adjustable. What you got is what you get. The ugly is when your not carrying a load the back end is a little stiffer and can bounce around a little if your not careful. Unloaded it's not terrible but I do notice it. Fortunately it's a truck and I'm usually carrying something.
