PSC Full Hydraulic Steering Kit 2.5 x 8 Single-Ended 1405X Pump
FHK200P
The PSC Full Hydraulic Steering Kit 2.5 x 8 Single-Ended 1405X Pump provides a single-ended full hydraulic steering package for custom off-road vehicles running 40–44-inch tires. The PSC 1405X pump supplies a 160cc orbital valve and 2.5-inch-bore cylinder for builds that need hydraulic steering control matched to a heavy-duty axle and linkage arrangement.
The package includes the FHA160-B accessory kit, PK-FHK-P pump package with remote reservoir, and SC2205K cylinder with 8 inches of stroke. PSC identifies GM big-block, small-block, and Vortec LS projects using a P-pump as the intended engine families. These are custom installations: pump mounting, cylinder travel, axle brackets, and linkage clearance must be checked together. A single-ended cylinder must be laid out for the actual axle rather than substituted into a double-ended installation without redesign.
Includes:
- FHA160-B 160cc full hydraulic accessory kit
- PK-FHK-P pump kit with remote reservoir
- SC2205K single-ended cylinder
- Hoses, fittings, mounting brackets, and PSC 715 fluid

FAQs
How is FHK200P different from FHK100P?
FHK200P uses a 160cc valve package and a single-ended 2.5 x 8-inch cylinder; PSC lists it for 40–44-inch tires. FHK100P uses a 125cc package and double-ended cylinder for 32–40-inch tires.
What is this kit designed to be used for?
Provides a single-ended full hydraulic steering package for custom off-road vehicles running 40–44-inch tires. The PSC 1405X pump supplies a 160cc orbital valve and 2.5-inch-bore cylinder for builds that need hydraulic steering control matched to a heavy-duty axle and linkage arrangement.
What installation checks matter most?
Verify mounting clearances, hose routing, and steering travel with the complete axle and suspension configuration. Keep hydraulic hoses clear of exhaust heat, moving components, sharp edges, and pinch points.
What is included with this SKU?
The Includes section identifies the listed package contents. Where options are offered, choose the matching model year or steering system; do not assume components listed for a different SKU are supplied.
How should the hydraulic system be prepared?
Follow PSC’s installation procedure for system flushing, approved fluid, and thorough bleeding. Confirm hose connections and inspect for leaks before loading the steering system.
Why does steering fluid cooling matter on the trail?
Repeated high-load steering inputs generate heat in the hydraulic circuit. Install the supplied cooler where specified, or plan suitable cooling according to PSC’s recommendations for the complete system.
