Perfect for the Pro4x/ Offroad Frontiers. This kit makes the Frontier look how it was supposd to look from Nissan. A 1.5" front lift spacer and 1" rear block will make the truck sit a bit taller and more level. Add cam bolts and you can clear a 285 tire on the factory wheels....and it looks great. With the 1.5" front spacers there is little to no percievable coil bucket contact and the factory bumpstops still function properly. The rear kit includes stronger 1/2" ubolts and our billet 6061. Stock rear shocks work great and the blocks will not promote wrap or spring sag.
