I believe the 96 and ups have the 26 splines.
and you will need to find a rear sammie center section machined out to fit the kicks axle.
THats also, I believe, to be avilable from Hawks Suzuki.
I got mine form a friend who installed an ARB up front and didn't need his anymore.
BTW. The Sammies rear center section has 4 spider gears where the kicks only have 2.
And since youll be running the 5:12s, you'll also need the pin can thingie that holds the spider gears pins in. (5:12s are too small to hold the pins in)
Cuase, If you broke yours, the spider gears will be bent ever so slightly and cause problems later.
It's hard to tell but learning by my freinds mistake. He's had to replace his front gears more than once to discover that problem.
Quote from article:Front end modifications for the Suzuki Sidekick You will need a ring and pinion retainer sleeve kit. This can be purchased from Hawk Strictly Suzuki or Spidertax. This kit is designed to put a Tracker/kick ring and pinion into a Samurai axle. This kit is a two-piece kit. Since we are putting a Samurai carrier in a Tracker/kick housing, we will only need the barrel from this kit. The barrel is to hold the pins for the locker in place so they do not hit the pinion. Assemble into the Steel housing.
