It is true that there is little aftermarket for Nissan 4x4s------ OH Well
It just makes for a challenge. It reminds me of building a Jeep back in the 1970s! You had to do most of the modifications from scratch!
Well you guys, You can do a lot with a stock Nissan with 31 inch tires anyway. If you want a seriously modified 4x4 you need more power, Big tires,
lower gears anyway. I know that a lot of guys think that you can just bolt aftermarket parts on to a factory 4x4 to create a modified rig, but I disagree.
You need MORE Engine-- like a Buick or Chevy V6 that has torque! -----Even with a Toyota or Jeep, you will usually want to do
an engine swap! So in the end, no aftermarket solution is NOT a simple solution anyway. You are also going to need lower gears! and stronger gears at that!
For Gears, even Jeeps and Toyotas get expensive and are not just bolt-on. If you have a Buick or CHevy engine swap, do the SM420 or SM 265
swap.
As for axles, the Jeep and Toyota gang trade axles all the time too, so why not do the same with a Nissan. A model 44 Dana or 8 inch Toytot solid front
axle.
So no matter if you have a Jeep or Toyota, ---------or a Nissan, IF you actually build a highly modified 4x4 you are going to change Engines, Transmissions,
and axles/suspension. Otherwise, why not just stick to a stock machine with 31 inch maximum tires???
In the end, a serious highly modified 4x4 is custom fabricated anyway.
