i want to gear my scrambler for more low end power and since i need to replace my chain and sprockets what size sprocket should i get to help me get the best low end with out loosing to much mid and top end power??

 

try an 11...u can try to find a used oen on ebay

 

NOOOOOOOOOOOOO!!!!!!!!!! you can not change your sprockets, tbsleeper u should now that. u will mess up your 4x4 for sure. jsut add a pipe and a filter and re jet.

 

Yup mudmaster250 is right.

 

Woah i had no idea, glad i asked, thanx guys[img]i/expressions/face-icon-small-shocked.gif[/img]

 

anytime

 

I want to bring this post up again...

Changing sprockets is no different than changing your tires to the same size tires front and rear. Several people have advocated that this is okay to do as it will only change the speed of 4x4 engaugement (and disenguagement).

Based upon this, I've done a little math...

Follow me here: The ratio of the stock tire circumferences front and rear is .957:1. If you want to change to the same size tire w/o affecting the speed of enguagement, you'd want to match up this ratio with your sprocket ratios. Basically, to match it up correctly, we'd have to take the stock ratio (13:36 or 1:2.7692) and raise the gear ratio by what you lost from the tire size difference. The closest combination I could find is 12:35 which is .949:1 different from stock. This means it would be .992:1 of the stock ratio. The question to ask is: since we're making the gearing in the rear (very slightly) shorter, it should enguage 4WD a little quicker, but how far off is the stock rear gearing from the front to let it outrun it to put it back into 2WD.

My guess is that it should be okay since we're talking such a small difference here. As the front tire rotates 100 turns, the rear would rotate 99.2 (compared to stock ratio).

 

uhh so that means u can change the gear ratio

well, it's not really changing the final drive ratio. It's actually changing the gear ratio to keep the final drive relationship between the front and the rear wheels as close as possible to stock. That's what's important for the 4WD system to work as designed. The 12 and 35 sprockets simply fascilitate the rear tires to be the same size and not mess with the 4WD system at all. Some people will tell you it's not going to make any difference as it is. Maybe that's true. I'm just working in theory to bring things back to the way they should be.

 

oh, and I almost forgot the best part of doing it this way. You get bigger tires, and therefore get your rear axle off the ground a bit more, but the gearing makes it seem as if they're a size smaller like they are from the factory. This will definitely help out at least a little in the torque department since you'll be losing some going to larger tires.
