The PSC SG441MR Ported Steering Box for your 1980-1991 GM 4WD Full Size Truck is built to be as tough as any steering gear on the market. PSC's years of experience has led to developing a line of steering gears that are built with a combination of time proven components that work off-road. Cases get full machine shop attention. They are honed, trued and sleeved if required. O.E. spool valves are completely dis-assembled, inspected, modified with proper T-bar, reassembled and tested for proper flow balance. All reconditioned components are inspected for wear, and are magnafluxed to find cracks that are not normally visible.
All steering gears modified for cylinder assist applications are built to flow fluid throughout the circuits as efficiently as possible. There is actually a science to getting a cylinder assist system to work at its optimum performance. When it comes to cylinder assist steering gears, PSC builds one of the best you will find. You must achieve a balance, and there's no replacement for over 20 years experience.
