2nd Gen Non-Engine/Transmission speedo gear question

[Mbschmidt]

i recently changed my '96 3500's tire size from 235/85R16 to 225/75R16 and would like to know what speedometer gear i need to get it calibrated correctly. the truck has a 3. 54 rear end gear and an automatic transmission. i called the local dodge dealer, but they were little help to say the least.

Use This Jeep Speedo Gear Applet and/or the info from Jeeps Unlimited to get the size gear you need. The 96 takes the short gear. Just got a 33T gear for my 96 from moparpartsamerica.com.
