Clutch Bell & Spur GEARING CHART

Post by SeeJeepGo » Mon Dec 15, 2003 1:00 pm

There are tons of posts about what gearing is better and what makes the difference, clutch vs. spur, etc. I put this chart together to see the relationship between the options and you can judge for yourself what works for you. If any of you ever worked on real cars, the similarity between the spur/clutch bell gearing is just like the rear end ring & pinion setup on a jeep or race car. For bigger tires you go to higher number ratio, and for faster top end on a race car you use lower numbers. This is the same with the Savage. If you have a more powerfull motor, try a setup with lower ratio cause when the motor revs out youll have faster top end. But if you want quicker accelleration off the line, use a higher number. Also if you run bigger diameter tires like Hotbodies or Big Joes, use a higher number to prevent bogging or clutch burnup. Also good for slower offroading like climbing or rocks. Also remember that certain setups may require modifications to the TVP. The list is sorted by ratio lowest to hightest. Notice some similarities like 52/17 is the same as 49/16.
