TORCH 1.5"-2" Rear Add A Leaf Lift Kit for 1999-2021 Toyota Tundra 4X4 2WD TRD SR5

Truck: 2016 Tundra CrewMax I used the instructions and some videos online, and the installation was actually easier than I was worried it would be. It gave me about a 1.5" lift, and the ride feels no different than stock. I got it to prevent squat while towing our trailer. I have not tried it yet, but I have had around 500lbs in the bed and it only brought the bed down a little. I do have some advice: -Get the entire kit (U-bolts and shims), you will need all of it -Watch a few videos online and decide for yourself the best way to install it (I did not follow their instructions exactly) -Do not include the overload leaf when you clamp the leaf springs, and keep the other leaf springs clamped the entire time (install at first step, remove at last step) -The overload leaf does have a pin, and WD-40 can help remove it -Do not compress this add-a-leaf with the single bolt on top, use a jack and the weight of the truck (raise the jack a bit, then tighten the bolt a bit, and then continue that until there is no light between) -I definitely recommend installing a sway bar (Amazon has them for cheaper than the TRD one) ***EDIT*** Not long after I added this leaf spring, my truck started creaking and popping when I articulated the axle. It took a while to figure out, but the issue is that the new leaf spring puts pressure on the original leaves that was not there before, and that was where the creaking was coming from. I separated the original leaves with a large screwdriver and sprayed white lithium grease very liberally. Now everything is quiet back there!

So far, these have been an outstanding upgrade! Paired with 5160 Bilstein shocks, Firestone airbags, Falken ATW4 35s, and a Hellwig sway bar, the added leafs have completely transformed my ride. The truck is smooth, stable, and far more controlled—definitely a huge improvement over running blocks. Couldn’t be happier with the setup!

2017 Tundra TRD Off-Road 4wd. Install was fairly easy and straightforward, but I did make a couple mistakes on one side, but the other side was much easier. There is a metal dowel on the stock spring pack that you will have to remove, I just hope the isolators on these things keep the springs aligned. I recommend going to a home improvement center and buying some thicker stainless steel bolts for the spring pack, I actually broke one of these that came with the sat while tightening it down. Mostly did these because I have a 17’ trailer now, so I removed the 2 inch lift blocks I had for better spring performance and load capacity, and of course it’s just better on your entire suspension overall compared to blocks. I also do some fairly technical trails while overlanding. I did notice because I carry a 12V fridge in my bed and have a camper shell, that it now sits about a quarter inch lower than my blocks did, but my truck is still 100% level, so I don’t really care. Can’t wait to hook up my trailer and see if it took care of that squat.

These were relatively easy to install if you know what you’re doing, and are incredibly worthwhile. The stock Tundra suspension is incredibly weak and seems to bottom out under less than half its listed capacity. I added these to my truck in addition to my existing RoadActive Suspension and SumoSpring bump stops, and it is exactly what the truck needed. Squat is absolutely eliminated when towing and the ride quality is still absolutely perfect. It added roughly 1 1/2 inches of height to the rear of the truck. Everything is now much firmer and the truck doesn’t feel like it’s being injured every time you go over a speed bump with a heavy trailer. Word to the wise - get the extended U bolts and shims. Both are required for install. Photo shows my Tundra with a 5,500 lb dump trailer (including cargo), still holding upward rake and not squatting.

Lifted/leveled my 2012 Toyota Tundra 4X4 with extra load capacity and no issues with them for a couple of years.

They explain it all

Perfect height addition to the back end. Virtually no difference in stiffness to the ride. The truck sits like it should now instead of squatting. During installation I could compress the spring pack together with the bolts provided down to about 1 inch of gap between the springs. I then put on the new u bolts to compress them all the way together which allowed me to tighten the nuts down all the way. Next I backed the u bolts off enough to slip the bump stop back in then torqued them back down. It's not possible to compress the springs all the way together with just wrenching the bolts and the weight of the truck.

Noticeable difference pulling our camper with my 04 tundra. Seems so simple but sooooo effective! Glad I got these before I spent LOTS of money on suspension
