PSC Full Hydraulic Steering Kit 1405X Pump for 32-40-inch Tires
FHK100P
The PSC Full Hydraulic Steering Kit 1405X Pump for 32-40-inch Tires combines the core full hydraulic steering components with a PSC 1405X pump package for custom off-road builds running 32–40-inch tires. It is suited to rock crawlers and similar GM-engine projects where the builder wants a matched valve, hydraulic supply, and double-ended cylinder rather than selecting each major assembly separately.
The 125cc accessory package is paired with a 2.5-inch-bore cylinder offering 8 inches of stroke and a P-pump system with remote reservoir. The double-ended layout must be mounted and linked to suit the axle’s steering geometry, with travel checked before loading the system. GM-based engine fitment still requires confirmation of the pump drive and bracket arrangement. Plan a fluid cooler, protected hose routing, and PSC-recommended fluid as part of the complete installation.
Includes:
- FHA125-B 125cc full hydraulic accessory kit
- PK-FHK-P P-pump kit with remote reservoir
- SC2212K double-ended cylinder
- Hoses, fittings, mounting brackets, clevis joints, and tie rod link kit

FAQs
Does FHK100P include the pump?
Yes. PSC lists PK-FHK-P alongside FHA125-B and SC2212K, providing the P-pump package as well as the valve accessory kit and cylinder.
What is this kit designed to be used for?
Combines the core full hydraulic steering components with a PSC 1405X pump package for custom off-road builds running 32–40-inch tires. It is suited to rock crawlers and similar GM-engine projects where the builder wants a matched valve, hydraulic supply, and double-ended cylinder rather than selecting each major assembly separately.
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.
