i have an 89 sidekick jlx 2dr with the stock 1.6L 16 valve and auto tranny.  i am planning on installing 33x13.5 super swampers, and i need to know what kind of gearing changes ill need to do.  can my suzuki handle 33s with stock gearing?  this is a daily driver, with weekend trips down tight trails and mudbogs.  if i need new gears, what company sells ring and pinions for my zuki?

calmini sells lower r&p's but what you can do is search the r&p from manual trannys, they are lower than auto ones, 33 will be bit big with stock gearing for daily use tho.

You can not get the rear 5.83 r&p's so forget that.

The 1600 16V 4 spd auto's have the same stock r&p's as the manuals so forget that too.

Gearing is a major problem unfortunately

wouldnt a 89 1.6l be the 8v?
 i dont think they switched to the 16v with the 2 drs till 95,and the 4drs in 92. if it is a 8v, then it should have the 4.62 gears,  you could switch to the 5.13's but i dont know if that would be good enough for everyday use, you could always get some new transfer case gears, that should be more than enough.

I ran a 16v and 4 speed auto with 33x9.5's. It is driveable but it does hurt. The best thing I did was alter the cam timing to bring the power in earlier. You may be able to hunt around and find some 5.6 diff gears.

Anyone daily drive a kick with 31's with stock gearing.  1.6l 8v manual.  How well does it do with only 31's. 

   My Kick has 31x10.5 and the 5.12 gears and its fine on the street.  Not sure about the 4.62 gears though.

calmini says that the transfer case gears only lowers high range on samurais, so that wont help me on the street.

I thought 89 kicks had 10 bolt rears if so Calmini should have 10 bolt 5.8 R&P's for the rear.

Blacknight,

I thing you will find the 10 bolt r&p's are for the smaller front 10 bolt diffs ( Vitara ) or smaller front and rear 10 bolt diffs ( 413 / Sammies ).

Hell if it was that easy I would go get a rear 10 bolt Vitara diff and do my r&p's. But sadly it is not  :'(

ZeusZuki 

so the front and rear 10 bolt r&p's are different sizes in a sidekick?

Yes, the front of a SideKick is the same size
as the front and rear of a Sammy, if there were
a way to use the front of a SideKick, or a Sammy
carrier in the rear of a SideKick, you could get 5.38
gears all day long, but sadly the 5.38 ratio is not
much lower than a 5.12 stock R&P from a manual
trans, but the Sammy gears are available from Yukon
for like $150 per set.

do sidekicks with auto trannys have different r&p from manual trannys?  mine has auto.  so...if an 89 kick with a manual tranny has 5.12's, and if mine is geared higher, i would benefit from the 5.12's, right?  how much would that help turn the 33" tires i have?  what ratio does mine have now?  4.62?  sorry if i dont pick up on this stuff real quickly, but im new to suzukis, and dont know too much about them yet, but im learning a lot.
thanks!

Calmini used to list 10 bolt rears, I used one in mine. Their web site only lists the 12s now and they are still shown as unavailable.

Yes, you are right, you have 4.62's now, and 5.12's from
a Man Trans would help, but 33's is a big tire, and tough
to rotate, I had them on with 4.62's and the turbo, but I
was afraid for the transmission (auto) so I got the 5.83's
to help reduce the load.

With the gear calculator I once figured out that 35" tires
make the 5.83's the same ratio as stock on 235 tires, unless
I did something wrong, but I show faster on the speedo than
my real rate of travel, so my calculation is probably right .
