Installed on 2015 Tacoma Double Cab. I'm loading a truck with about 500 pounds. + - Goods for camping. I have a Lear Topper and a T@B Teardrop Trailer. SUMO springs (1000lb) keep the rear of the truck level for a great ride and eliminate most of the sway. I am 72 years old and did the install myself using a jack and a very good scissor jack. Use a 54mm torque wrench on the U-bolts. Check torque after 500 miles. I wish I had installed SUMO springs a few years ago. Good price, great guarantee. The unloaded ride is a little stiffer than the stock Tacoma suspension, but quite comfortable and better in my opinion.
