Like others out there that didn't get the 8 way seats in their trucks, I am very unhappy with the adjustment of the stock seat. So much so that I planned on getting rid of my frontier. I am a tall guy at 6'3" with very long legs. Without being able to tilt the seat up my only parts contacting the truck are my hands, heels and tailbone while driving. I decided to see if there were any modifications I could do to save me from having to get a different truck.
I searched around and didn't see this on the forum, so please delete or merge if this is old news.
Its a very simple mod that only requires a few things.
Stack of 5/16s fender washers
2 8mm X 1.25mm bolts (length dictated by stock bolt + the amount of washers used)
2 lock washers
First remove these 2 bolts
Then insert your washer stack and new longer bolt with lock washer.
I'd say use your discretion on how many washers to use. The rear of the cushion is still bolted down and the mounts are being flexed. I still plan on finding a 8 way seat from a wrecking yard but for a couple bucks and a few minutes of work you can be a bit more comfortable.
Why the SV with a premium package comes with the basic seat is beyond me. You'd have to add the appearance package most of which I'd pay to not have on my truck (big wheels, giant sticker, white gauges) just to get the good seat. Nissan, if your listening please included the 8 way seat in the SV trim level, also sell the part for a decent price so owners can add it later instead of being SOL.
Hope this helps out some others and Cheers (beer)
