Sweet Manufacturing's standard servo control valve for power steering. For use with rack and pinions that utilize integrated servos such as Howe Performance, Fortin Racing and Sweet Manufacturing.

If you're trying to replace a servo already on your car/truck/vehicle, if you look carefully at the old servo, Sweet always engraves the torsion bar size into the control valve. The thicker the torsion bar the stiffer your steering will feel. The thinner the torsion bar is, the softer/easier your steering will feel.
