Outfit your semi truck to be Ready for the Road Ahead with smooth and reliable steering, with the CRC Sta-Lube Power Steering Fluid. Thanks to its ability to transmit hydraulic pressure from the steering wheel to the steering mechanism, this replacement fluid allows operators to efficiently change directions without excessive wheel play. Increased steering effort, vibrations, warning lights, and other similar types of issues can all be signs of low fluid levels or a potential leak. FleetPride is your First Click in Heavy Duty .
