Default 4x4 questions and upgrades

I have a 1997 Nissan Pickup Se 4x4 5 speed manual and have some questions about it. I do a fair amount of off-roading and its also my daily so keep that in mind. I would like to make it a more capable rig then it currently is and don't really know where to start. So first question is about ifs. Is it possible to make ifs better without sas? I've heard lifting it makes it ride rough. Second is what can I do to get more power and low end from the ka24e without swapping? its done ok so far but I would like to be able to pull out on highways without too much difficulty and climb a little better. Also since this is my first post I wasn't quite sure where to post this so sorry if its not quite in the right spot.

Welcome to IN... no worries on your first post. You have a 4x question...

So, how "stock" is your copy? Got a PIC? (we like eye-candy)

Probably at least as bad as a Jeep so worse than a cow.

Dunno what you mean about make IFS better. I've taken my truck to Moab, run fins n things on 235/75/15s and had jeeps getting out of my way. If that's the kind of thing you do you'll be fine.



Look into idler arm braces as those like to break with serious off road.



The KA doesn't make a ton of power. Some.of the 4cyl guys should be able to chime in there.



Turning the t bars up on IFS will make.it ride rough and flex.less. It will also wear out CVs quicker with the more aggressive angle.

I have one of the idler braces. It really stiffened the steering. The brace fixes one of the worst design flaws the 4x4 chassis ever had.

From what I understand its completely stock. Ive looked at the idler arm brace and from what everyone says I think it would be worth it since its pretty rocky on the trails. Ive been thinking about some larger tires due to some slight scrapping on some trails where I live. Is there a way to get the from end to have more clearance without torsion bars? Also my suspension is clapped, anyone know some good suspension?

I'm guessing you have HG46 axles which is nice. There are several ways to make the truck more capable.

Obviously, the idler arm bracket.

31" tires,

Find a pathy in the junkyard with a V6, HG46 axle code, and LSD (limited slip differential). Pull both axles. Or get a lunch box locker like Loc-Rite.

The LSD will allow for lifting one rear tire and not getting stuck. The front axle from the pathy is a R200 which is a little bigger than you're R180. You can then get a R200 LSD and install that.

You will have to crank the T-Bars to raise the front end up. The key thing is to leave room for down travel.

How would the hg46 code work. Would I just have to take it from a pathy and then put it onto my computer? And then it would just be putting the axles onto my truck? After that then I could but the lsd on fro the front. Just making sure I read that right.

HG46 denotes a H233b axle with 4.6:1 gears.

Yes, the HG46 is the axle code. You can find it on the door jamb sticker.

It's not a simple as it sounds. The pathy rear axle is a 5-link suspension. But you could swap the center chunks but need to measure that axles as the axle shafts are shimmed to the housings.

The front axle will just swap out but you need to possibly swap the outer shafts if the spline count is different for the hub. (some years the hubs had different splines 27 or 29 IIRC)

@Dave, his is a '96 like yours. I thought those were already R200A in the front with the 29 spline axles.


The best upgrade you can make is to add a winch.

I say keep it at stock height and challenge your driving skill. Lifting gets expensive and can leave you bent or broken on the trail. Better to ride the trails than ride on the trailer.
That said, all of the above info is valid from my experience.

Deerhurst is stock IFS and has done some respectable wheeling with it.
dvdswan has been through the evolution from stock to linked SAS with a 5.3L v8.
I have been through the axle swap he described, plus aftermarket arms, Sway-a-Way t-bars, and Calmini steering before going SAS and 5.3L v8.
But if I had a stock one in good shape today, I would keep it that way and challenge myself to see what I can get it through. It was fun in the beginning, then it got tough for several years. Now it is fun again, but not the same truck. Not by a long shot.
