Changed dad to a chain drive last year. His gearing was 5.13 rear and 4.88 in the front. We ran a 23 tooth sprocket at both ends because we wanted the gears staggered. Running 32x14 scoops in the rear, and 14.50 DT's in the front. Putting a 9" rear in and going to a 5.43 gear.

So....how do I figure out my sprocket I need so I can get the staggered gearing so it's the same as it was with the 5.13/4.88? How do you figure out the tooth count?

OK, I have a second. This is purely and example since I don't know the rollouts of your tires.

Rear Tire Rollout / Rear Gear = Front Tire Rollout / X

or Reararranged: X = (Front Tire Rollout*Rear Gear) / Rear Tire Rollout

X = Needed front gear Ratio. So if you have a 4.88 and you need a 5.13 you need to slow down the front. That would be a gear ratio for the chain drive of: 5.13/4.88 = 1.05

So in your case you would need a 1.05 Chain Drive Ratio. So if you have a 23 sprocket at the trans you would need a 24 on the front driveshaft. (24 / 23) = 1.04 That would make you about 1% overdriven on the front. Always be a little overdriven so you don't end up in big trouble in the shutdown area.

Hopefully everybody else that figures these agrees with me.
