Adjustable VSSB

Quadstar Tuning LLC

We offer these modified VSSB (Vehicle Speed Sensor Buffers) to correct your speedometer reading, shift points, and torque converter lockup MPH after changes in gear ratio or tire size.  In order to correct all of the above, you need this module on both stock or tuned trucks.  If your speedometer doesn't match a GPS reading, then this will fix it. 

These come pre-set for gear ratio and tire size you specify and are adjustable if you ever change the vehicle in the future. For example, if you go from 31 to 35" tires, you can adjust the switches and correct the speedometer without buying another VSSB!

Full adjustment instructions are provided via email for each order.

Fits all 1994 or newer 6.5L Diesel vehicles. Both OBDI and OBDII vehicles use the same VSSB, as do automatic vs manual trucks.

*Core return label is included, for domestic USA shipments
