Modified GM DRAC – To Adjust for Different Tires / Gear Ratios – TBI

$119.99

SKU: WTB005 Categories: ,

Description

These DRACs have been modified with a 6 pin DIP switch to enable calibration for different tire sizes and gear ratios. This style works with the ’87-92 style ECMs like the 1227747 and is also used in 1993 TBI trucks. Instructions are included. If your setup has the DRAC built into the gauge cluster, this probably isn’t a good replacement. If you need the ’94-95 style VSSB instead, let us know.
