How Do You Determine The Axle Ratio In A Dodge Ram?
When determining the axle ratio in a Dodge Ram for the purpose of changing to a different ratio, several things should be considered. On newer vehicles, the shift points in the transmission, the speedometer and the cruising rpm will change accordingly. On four-wheel-drive vehicles, both the front and rear ratio must agree. The higher the number of the ratio, the lower the gearing. For instance, a 4:11 gear means the driveshaft will turn 4:11 times for every revolution of the tire. Conversely a 3:50 will turn three and a half turns to every revolution. A high number will give more acceleration and less top end, with the reverse for a smaller gear. Look on the rear axle carrier housing for a metal tag with the gear ratio stamped on it. In lieu of a tag, proceed to the next step. Raise and support the truck on jack stands. Place the drive pan under the carrier housing cover. Remove all the 13mm bolts in the cover on the housing, using a socket. Pry the cover off slowly from the bottom, pa
