Review on 🚀 Enhance Your Toyota Tundra/Tacoma with Readylift 66-5001 1" Rear Block Leveling Kit in Stylish Silver by Kurt Manning

I am giving three stars because the blocks and u-bolts work and I had no problems installing them on my 2000 Toyota Tundra except for the nuts that came with the kit. As you can see in my picture the nuts have what appears to be screw retaining threads that lock them in place, breaking the u-bolt and being exceptionally difficult to tighten with a hand tool. The nut got quite warm as I tightened the bolt, so I stopped, unscrewed it with even greater difficulty, and then put in the original washer and nut from my truck. After threading this original nut onto the same bolt, I got to the point where threading was difficult because the ReadyLIFT nut was messing up the threads. Once past that point, I was able to finger tighten the truck's original nut and finally apply 98 ft-lbs of torque after installing all four of the original washers and bolts. ReadyLIFT nuts are not suitable for this application.
