Most likely will be 3.55s. Gearing won't give it any more power but if you have bigger tires it will help turn them and get some of the stress off the tranny.

True, lower gears will not give an engine more power, but the torque at the axle will be increased so it will feel like more power.

Neither hp or torque will change by changing gears........ mechanical leverage will change.....toe-may-toe, toe-mah-toe. LOL A ratio numerically higher than 3.55 will feel like a little more power, if all else stays the same.

gearing will only make it seem like you have more power, like every one said. you might be able to get goin faster but your top speed will be down. if your goin with bigger tires you would want to regear. if so what size tire? if your looking for more power go with a bored tb, new exhaust and a cold air intake.

True torque at the engine will be the same. Torque at the wheel will be higher when lower or numerically higher gears are used. Mechanical leverage on a rotating mass is torque.

check randys ring and pinion, thats where i got mine at, they start at like 130 a set for the r&p. 410s would be a good gear, if your running 31s+ id go somewhere between 456s and 488s
