12.5" Square U Bolts 2.5" wide 9/16" Ubolt

Add a Leaf made all the difference

I installed the TORCH 1.5"-2" Rear Add A Leaf Spring Lift Kit for my Nissan Frontier PRO-4X. The rear leaf springs were totally flat. I had previously installed a set of override rubber bumpers, and the frame rails were riding on the bumpers 100% of the time with only the weight of my tools in the bed. This was even worse when towing my GoneCamper cargo trailer. As advertised, the Add- A-Leaf added 2-inches. With the extra leaf and the override bumpers on top of the spring mounts, I needed the longer U-bolts. They were obviously WAY too long, but easily cutoff to fit. My truck rides slightly higher unloaded, but perfectly level with my trailer now. GREAT product!. PS. My local shop charged $250 to disassemble the rear leaf springs and install the Add-A-Leaf kit.
