DISCLAIMER: Leaf springs are shipped and handled in bulk and we consider them to have a "trail-ready" finish. Meaning the finish is not perfect and may have some scratches and other small blemishes that do not affect performance. If you would like the finish on the leafs to be flawless, then we recommend a DIY method such as painting them before installation. The image below is how leaf springs are shipped from Z1.

I was concerned that these would give my Frontier a rough ride, but they haven’t. They are much better than the OEM suspension. I installed them with new Bilstein shocks, and a new bushing kit. The ride is much smoother. They also lifted the back of my truck over three inches. I have a truck bed slide in camper, so now I’ll ride level front and back.
I definitely recommend these leaf springs.

Great springs but I do think they were a little stiff for my truck and mine is heavier than most. If I could go back I would’ve gone with the regular Heavy’s.
