Description
Custom Ratio Adapter, Speed Up or Slow Down your Speedometer with a custom built ratio percentage.
The male side can be turned 180 degrees, just remove the 4 screws and flip one side to make it offset.
This adapter is only used at the transmission or at the transfer case, not behind the speedometer head.
Unfortunately we cannot refund special orders, but we can rebuild your adapter for a rebuild fee!
So if your new percentage is not working out for you, give Jim a call!
If you need assistance with figuring out which percentage you need, please call us with these speed readings:
| When your GPS shows: | What your Speedometer displays: |
| 40 mph | ?? |
| 50 mph | ?? |
| 60 mph | ?? |
Please be sure to give us these readings in this EXACT order (40,50,60) to prevent receiving the incorrect percentage.
For information, please call 888.201.2066 or send an email to jim@transmissioncenter.net
