I would like to upgrade the gearing a bit on my x-90 , 1997 , 1.6l , 16v .... i am running 30" bf mud terrains now but may get 31's next ...what would be the ideal pinion and ring gear ratio for me to drop in it ? Right now i have no take off power till i get up over 3000 rpm which sometimes takes awhile, especially on the hills.
Would just changing the rear ring and pinion do the trick ? the front end is stock independant , i wouldn't really need to modify this as well would i ?
And where is the best place to get a good ring and pinion gear set for my x-90 ?
-
The optimum would be the factory 5.63 gears. They would have to be sourced used as they are no longer carried by Suzuki and no one makes R&P's in the aftermarket for the sidekick/tracker/x90. Expect to pay a premium price.
-
Really , noone makes aftermarket gears ? so what can i look for when parts searching to determine the gear ratio of the rear end ? and compatibility ?
-
What would my stock rearend be running for gears? just woundering the reduction % from stock to 5.63 ?
-
The stock X90 should be 4.66s or thereabouts so you would get a reasonable reduction with the 5:12s from a 5sp Track/Kick
-
The factory offered the 5.63 and a 5.38 R&P on a very limited amount of sidekicks years ago, Calmini used to have a 5.88 but they were discontinued. Those are your only real options, if it fits a sidekick it fits the x90 as they have the same frame and drivetrain, just different bodies.
Not sure what your current gear ratio is, what transmission do you have? I am not for sure positive but I thought i remember reading some x90's didnt have 5.12 R&P from the factory so that would be an improvement.
Another option is to go with a 260 torquer cam and a Doug Thorley tri-Y header for more power down low in the rpm range where you are mostly driving.

Yah it definatly need more power ...lol , i have found a couple site that are selling 5.38 ring gears but they are backordered . How hard is it to change a ring and pinion on these zukies , will i have to heat the ring gear like i've seen others do , i have never changed one before , quick learner though !! I also discovered 4:62.1 tranny case gears for low range torque %134 gain , might be a future upgrade .

I just installed 4.24:1's in my Tracker TC..very high crawl reduction..redline in low range 5th is 25mph!!
-
That sounds too low for my driving applications . I use my rig for hunting and playing , dirt roads and maybe logging trails .
-
That is exactly the types of terrain I drive on in the mtns, mostly logging/skidder trails, hunting, and back/dirt road driving, as well as just running into town(20 minute drive on dirt and pavement).
I am running 31x10.5's with 5.12 gears in my 98' Sidekick and she is slightly down on power, the 4.24 transfercase gears are the very next upgrade planned here shortly, even before the torquer cam.

Buddy just posted a t case with those gears in it for 550.00 in classifids .
-
you need around 5.62 to bring you back to stock. trying to get to the same place.
-
I wouldn't even mind having a little better out of the gate punch than stock , she only goes 100 km's /h full out now , the lower gears will will cause me to loose even more top end speed won't they ? still a good trade off !!
-
You will gain power everywhere and get a hiigher top speed, with your current gearing the engine just cant provide enough power to get to a higher speed.
-

I don't think any X90s had 5:12s from the factory
-
If i just swap my rear end with a sidekick rear end that should do the trick ...or should i swap front ends as well ?
-
You must make sure both differentials are running the same ratio.
Put 5.125 diffs in (easy to find), and with 30-31inch tires you'll be back close to factory gearing.
FYI, your x-90 came with 4.625 diff gears stock.
-
A couple of things.... Rhino is correct, X-90's did NOT come with the 5.12 gears They are 4.?? stock so a factory 5 speed Kick R&P will help you out and they are easy to come by.
Second, (I dont know if this was covered) The T-Case reduction is an AWESOME addition to any trail 4x4 BUT the Kick/X-90/Tracker reductions leave high range stock, there will be no on road benefit/rediction, so done be expecting it.
And Last (yea, I know, more than a couple) ;), there was a company (one of our sponsors) that was coming out with a in line reduction about a year or so ago. I can not remember who or what it was called, but one hell of an idea.... Hopefully someone else can jump in here and remind me who/what it was.

I'm suspecting you're referring to trail tough and the Undertaker (http://www.trailtough.com/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=233&category_id=46&option=com_virtuemart&Itemid=53). While I find it a nice solution, I just don't think it's worthy for a SWB trac/kick ...

Yeah, I remembered it was something like that. Simon Touron who built Generation-X90 years ago put a 5:12 axle in his and it wouldn't go anywhere in 4wd! it stuck in my mind ::) ::)
