I know the 3rd gen Tacoma are using them I just wanted to know if any one try them on the frontier I believe there longer. I'm debating to get 5100 and just use 607 or if 888 well work I have 2017 frontier
If its made for a Tacoma, they won't work on 5100s made for a Frontier as the spring perches are a different size. If you swap the spring perches to those made for a Toyota then they would fit but your guess is as good as mine regarding lift heights, ride quality, etc.
Typically, Toyota likes to use higher rate springs compared to Nissan. That coupled with the fact that you say they are longer will probably mean a stiff ride and too much lift.
