THP/PCF Series Power Steering Gears (North America)
Enhanced Performance and Compact design
The THP/PCF Power Steering Gear performance has been improved over the current gear design in several ways. A faster steering ratio provides improvements in lock-to-lock turns. Lower internal gear friction enhances the return-to-center response. And, the optional PCF feature improves the steering gear on-center feel, without an increase in steering park efforts.
Advantages
- Increased pressure
- Lightweight design
- PCF (positive center feel) option
- Reduced package size provides increased wheel cut
