The 1st gen frontier has the ability to adjust ride height via "pre-loading" the torsion bars... or as its better known as.... adjusting or cranking them.... Basically the torsion bar is a spring... It is connected to the LCA (lower control arm) in the front of your truck, and connected to a crossmember and adjuster in the central area of your truck. If you look under the truck, you will see on each side, just inside of the frame rails, a long bar that extends back from the LCA.. thats your torsion bar...
ALL LIFTS with the exception of very high dollar SAS or Coil Over conversion lift your truck via a torsion bar crank... Some kits have the option of upgrading to aftermarket torsion bars, but this is NOT needed.. some prefer, some prefer stock bars... The stock torsion bars have more than enough ability to give you well over the maximum 3+" of lift.
0" to 2" - You can simply adjust your torsion bars...
2.5" to 3" - You can either purchase a complete lift kit, or purchase aftermarket UCA's
To adjust your torsion bars... You simply jack up the front end of your truck, secure it with the wheels slightly off the ground, to remove any tension on the front suspension, and tighten the adjuster bolts.. There are two 19mm nuts on the top of the adjuster bolt... the top being a lock nut... simply loosen the top nut, then tightned the adjuster bolt to adjust ride height... lower truck, measure... and repeat untill you have desired height.... REMEMBER.... you want a minimum of 1/2" of room between the bottom of your UCA, and the bump stop which is below it.....

It is said to always get an alighnment after adjusting torsion bars, however in MOST cases, it will not effect your alignmnt, however this is YOUR CHOICE... if it needs the alignment, GET IT DONE.
You always have the option of purchasing a lift "kit" that is complete with all that is needed... However there are lots of people who do the lifts in steps... Lots of people start off with a simple torsion bar adjustment, then decide they want more.... Here are your options...
1) Add aftermarket UCA's. Basically as you adjust the height of your truck with your stock UCA's, the angle that they sit changes, which also changes the ball joint angle and slightly changes your camber. Aftermarket UCA's DO NOT ACTUALLY LIFT YOUR TRUCK... The torsion bars do... The aftermarket UCA's are simply designed at a differant angle, so that when the truck is adjusted by 2.5-3", the ball joint angles, and your camber are at the correct points... There are several options, and most of them are in the $350.00 range.
AS I UNDERSTAND IT... Now keep in mind, because we use torsion bars, there is the ability to adjust... but... the lift amounts below are what I've come to understand the aftermarket UCA's to be designed to provide...
AC (4x4parts) and Rancho - 2.5"... both of these are almost identical.
Calmini and SLR Econ's - 3"... both of these are almost the same exact design.
SLR Stage series - 3" plus added down travel....
STOCK TORSION BARS VS. AFTERMARKET
Aftermarket torsion bars are basically the same thing, except they have a higher spring rate... Basically they are stiffer... Some like this, as they feel them to be stronger, some don't because its said that the stock bars will flex better... This is 100% a matter of personal preferance...They are NOT needed to achieve the lfit..
RE-INDEX - In the even that you are adjusting your torsion bars, and the adjuster bolts run out of adjusting room.. (the brackets they go through have no more movement available)... you can reindex the stock bars... Basically the ends of the bars are splined... you simply remove the adjuster bolt, back the bars out of the ends... rotate them by 1 or 2 splines, which will give you the extra ability to adjust higher...
SHOCKS... With a simple torsion bar adjustment, its not requried to upgrade shocks, but lots of people do.... If you are lifting to the 2.5 to 3" range... you will need to upgrade...
Now... There are wide spread comments on the good/bad effects of adjusting your torsion bars.... As most of us have found... There really is no DOWN side to doing this....
Will your truck's ride get stiffer due to adjusting the torsion bars? NO!.. however people do tend to say it does... And the reason has little to do with the torsion bars, but more in the fact that they are adjusting to much. When you adjust your torsion bars for more lift, you are changing the angles that your control arms sit. Just under your UCA (upper control arm) there is a little black rubber bump stop. This is there so that when the front end goes up, and the wheels "droop" or drop down, it prevents the suspension from drooping to far, and causing your CV's (axles) to bind, and possibly brake. Normally when you go over a bump, your front suspension has plenty of room to travel before that bump stop, so it never actually contacts it. But by lifting more than 1.5-2" this way, you are causing the front end to contact those stops more than regular, resulting in what seems to be a stiff ride. Worn out shocks can also play a part in this, however the simple answer, is distance between UCA and bump stop... You can purchase "low profile" bump stops from Nissan Parts, Nissan Truck Parts, Nissan Suspension Kits, 4x4 Parts | 4x4parts.com
which can help with some of this.
you have 3 basic options....
3) AAL's (add a leaf) or custom leaf packs.
I personally don't like blocks.. but they work... but i won't go into details on the
SHACKLES... You have several options... the aftermarket parts places listed do sell them... OR... AutoZone and several other places do sell universal ones that can be used for aprox $14.00... The aftermarket ones available are stronger, but the universal ones are usable... Shackles will provide the most flex of all these options...
AAL's.. they sell Add A Leafs that range from cheaper 1pc to more exspensive 3pc sets... This is the BEST way.. however they don't flex as good as shackles, so lots of people combine shackes and aal's..
