Review on Timbren Suspension Enhancement System - TORTUN4L: Boost Your Vehicle's Performance by Mohammed Prude

I'm not a mechanic but I can follow instructions and do basic car maintenance. Thanks to the manufacturer's instructions and watching some YouTube videos, I was able to easily install the timbrens in about 15 minutes per side. Essentially jack up under the car and mount a separate support (to relieve pressure) from the rear leaf spring, remove the tire, mark the tops of the leaf spring studs (where they meet the axle) with a marker, remove Bolt from the center of the leaf spring, remove the fender and simply replace with Timbrens, align the bolts with the sharpie marks, tighten the bolts to spec, reinstall the tire, tighten the lugs firmly, lower the vehicle and repeat the process on the other side. Then I attached my trailer - no more sagging. The headlights are aimed directly in front of the car while driving, there is no restless jumping. Since without a trailer (and an unloaded platform) there is about a 1/2 inch gap, my Nissan Frontier drives perfectly as if nothing has changed. The perfect solution for my purposes!
