They will work with 4 cylinder frontiers.
They are a direct bolt on replacment hub, CNC machined Chromoly steel, bullet proof, I have been selling them for 7 years and never had 1 complaint! there are lots of guys on here using them, especially for mazdas. They are more reliable than swapping toyota parts, as they are machined to the exact specs of the factory hubs (other than bolt pattern of course), and toyota hubs and spindles are made for toyotas not nissans! All hubs are 2 bolt patterns 5x4.5" (114.3) and 5x4.75"(5x120)
They use factory bearings and seals, a slightly different brake rotor and thread in (euro style) wheel studs. Included in the $240 is just the hubs for nissan, the rotors studs bearings and seals are extra. I can supply you with part numbers for the brake rotors so you can get them yourself if you wish. I recommend buying the rotor to hub bolts and wheel studs from me as they may be trickier to find for you, cost $55.
