SSR-610-40 | SumoSprings Rear for Toyota Tundra, Toyota Tacoma, Nissan Frontier, Nissan Titan

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.

Mounted on 2009 Toyota Tacoma Crew Cab TRD. Incredibly pleased with the performance.Easy installation with socket wrench and torque wrench.Empty Truck Daily Ride: Ride is tighter. Do feel bumps a bit more, but this is a truck - not a luxury car.Minimizes rebound from heavy breaking. (yes my shocks are good)Empty Truck Off Road: Ruts can bounce you around as there is less absorption, but nothing you cannot get used to.Loaded Truck to the Dump: Level and stable, rounds out bumps with ease. no bottoming out on big bumps.Towing Loaded 16' Camper: No more "see saw" smooth ride, actually better gas +1.5 MPG as ride is smoothed out.

after 5 years air bag blew out on drivers side causing truck to ride hard on bumps..big job to replace for me with everything rusted so planned to grind them off when I came upon these suggested by another person in same situation. Much easier install but I should have sprayed spring nuts with penetrating oil days before. Used air impact to loosen nuts, battery driver did not touch them. Ride is a bit retro truck but comfortable and helps keep nose down trailering livestock

Install was easy to do with the right tools. No negative effects felt with empty bed. Drives amazing with weight in the back. Pleasantly surprised at how effective this product was at reducing bed.

These are good and stabilizes the rear of the truck. You will bottom out on them but they provide a stiffer ride and hold the rear especially under load.

What a world of difference from stock...I had never heard of these before and how easy it is to install them (plenty of youtube videos on this) I was a bit skeptical at first but not that I have then installed I am super glad I did. My only complaint is the price, I wish they were a bit more affordable or go on sale that would be great but other wise it is an awesome product and would highly recommend for a much better ride quality.

Inexpensive way to solve and otherwise very expensive problem. I recently added a four wheel camper to the back of my Tacoma. The camper itself weighs around 370 pounds empty so after it’s loaded up it sags the rear end quite a bit. My truck already has after market leaf springs but after I added these the truck drove completely different. It is stiffer but it greatly smooths out the ride and overall handling of my truck even with all the added weight.This is a great product, highly recommend.

These served me very well when towing trailers and campers. Also for over loading my tacoma. They really help for stability and eliminate sway.However I've now had them on for 2 years. I don't tow or load much in the winter so not sure when this happened but they have fallen off. I found one on the road near my home. The adhesive which holds them to the bottom mounting plate let go. I think for the money they should have better longevity.Supersprings did send me a warranty replacement but when the replacement falls apart, I will definitely be going with Timberin for my next set. Other brands like Timberin have through bolts to hold them on.
