CPP POWER STEERING BOX COMPARISON


| CPP Series | Best Suited For | Primary Advantages | Fitment Considerations |
|---|---|---|---|
| 400 Series | Compact classic-car and custom conversions | Small housing, quick response and manual-box-style packaging | May require column, linkage, pitman-arm or clutch-linkage changes |
| 460 Series | Classic truck manual-to-power conversions | Larger internal bore, increased assist and compact frame-rail fitment | Verify column type, mounting brackets, pitman arm and engine clearance |
| 500 Series | Popular GM cars and C10 trucks | One-piece housing, new components and modern steering feel | Confirm input shaft, sector shaft, hoses, rag joint and column requirements |
| 575 Series | Modern performance-oriented steering upgrades | Dual thrust bearings, progressive valve, large piston and improved stability | Availability and included components vary by vehicle and kit |
Important: Specifications vary by application. Always confirm the individual product listing before purchasing.
HOW TO CHOOSE THE RIGHT CPP POWER STEERING BOX


| Selection Step | What to Check | Why It Matters |
|---|---|---|
| Start With the Exact Vehicle |
Identify the vehicle’s:
|
Similar-looking vehicles may use different frame mounts, steering linkage, pitman arms, sector shafts, input shafts, or steering columns. |
| Identify the Current Steering System |
Determine whether the vehicle currently has:
|
A manual-to-power conversion may require more components than replacing an existing power steering box. |
| Check the Steering Column |
Confirm the column type and output before ordering:
|
Some installations require shortening the original shaft, replacing the lower shaft, adding a rag joint, or installing a steering U-joint. |
| Verify the Pitman Arm and Sector Shaft |
Confirm:
|
The pitman arm connects the steering box to the steering linkage. Do not assume the original pitman arm will fit a new steering box unless the product listing specifically confirms compatibility. |
| Confirm Hose and Port Compatibility |
Power steering boxes may use:
|
The pump, pressure hose, return hose, and steering box must use compatible fittings. Adapter fittings are available for many pump-and-box combinations. |
| Match the Power Steering Pump |
Verify that the pump provides the pressure and flow required by the steering box. Vehicles using a hydraulic brake-assist system such as CPP HydraStop must have a pump configured to support both the steering and braking systems. |
Too little assist can make the steering feel heavy. Excessive pressure or flow can make the steering feel overly sensitive or contribute to leaks and heat. |
| Check Engine and Chassis Clearance |
Inspect clearance around:
|
Clearance requirements can vary with the engine, transmission, headers, steering column, and previous vehicle modifications. |
| Decide Between a Box and a Complete Kit |
Choose an individual gearbox when the remaining steering and hydraulic components are already compatible. Choose a conversion kit when the vehicle also needs items such as:
|
A complete application-specific kit can reduce guesswork and help ensure the major components are designed to work together. |
Important: Steering-box specifications and included components vary by vehicle and part number. Always confirm the individual CPP product listing before purchasing.
POWER STEERING BOX INSTALLATION OVERVIEW


Power steering box installation varies by application, but the general process may include the following steps:
| Step | Installation Process |
|---|---|
| 1 | Disconnect the battery and safely support the vehicle. |
| 2 | Remove the steering shaft or disconnect the original steering column. |
| 3 | Disconnect the pitman arm and steering linkage. |
| 4 | Remove the original steering box. |
| 5 | Install any required frame brackets, mounting plates, or reinforcement components. |
| 6 | Position and securely mount the CPP power steering box. |
| 7 | Connect the correct pitman arm and steering linkage for the application. |
| 8 | Install the required rag joint, steering shaft, coupler, or steering U-joints. |
| 9 | Connect the power steering pressure and return hoses. |
| 10 | Fill the power steering reservoir with the recommended fluid. |
| 11 | Bleed trapped air from the hydraulic system. |
| 12 | Inspect all hose fittings, mounting hardware, and connections for leaks, looseness, or unwanted movement. |
| 13 | Check the steering-wheel position and verify the vehicle's front-end alignment. |
Power Steering Box Installation Tips
| Tip | What to Check |
|---|---|
| 1 | Center the new steering gearbox before connecting the pitman arm and steering wheel. |
| 2 | Never force a pitman arm onto an incorrect or incompatible sector shaft. |
| 3 | Route hoses away from headers, exhaust components, sharp edges, belts, and moving suspension parts. |
| 4 | Use fittings designed for the steering box and pump instead of stacking unnecessary adapters. |
| 5 | Do not use thread-sealing tape on flare or O-ring connections unless the product instructions specifically require it. |
| 6 | Completely bleed the power steering system before driving the vehicle. |
| 7 | Do not hold the steering wheel against full lock for an extended period. |
| 8 | Recheck the mounting bolts, hose connections, couplers, U-joints, and steering-shaft fasteners after the initial road test. |
| 9 | Complete a professional front-end alignment after major steering or suspension changes. |

FREQUENTLY ASKED QUESTIONS


| Question | Answer |
|---|---|
| Can I convert a manual-steering vehicle to power steering? | Yes. CPP offers application-specific power steering boxes and conversion kits for many classic cars and trucks. The conversion may also require a pump, brackets, hoses, pitman arm, steering shaft, rag joint, linkage components, or column modifications. |
| Will a CPP power steering box bolt directly to my frame? | Many CPP boxes are designed for application-specific installation, but the exact requirements vary. Some bolt directly to the original mounting location, while others require mounting brackets, spacers, reinforcement, or frame modifications. |
| Will my original pitman arm work? | It depends on the gearbox and vehicle. The pitman arm must match the sector-shaft diameter, spline pattern, master splines, length, and linkage taper. Check the individual product description before reusing the original arm. |
| Will I need to modify my steering column? | Some conversions require shortening or modifying the original column shaft. Others use a replacement steering shaft, rag joint, coupler, or U-joint. Aftermarket columns may also require application-specific adapters. |
| What does the steering ratio mean? |
The steering ratio describes how much the steering wheel must turn compared with the movement of the vehicle’s front wheels. A numerically lower or quicker ratio generally requires less steering-wheel movement, while a slower ratio usually requires more movement. The correct ratio depends on the vehicle, tire size, suspension geometry, intended use, and desired steering feel. |
| Can I use a CPP box with an aftermarket steering column? | Often, yes. The column output, shaft size, spline count, required collapsibility, and available space must all be verified. A compatible rag joint, coupler, shaft, or U-joint may be required. |
| Can I use a CPP power steering box with headers? | Many applications can be used with headers, but clearance depends on the vehicle, engine, header design, engine mounts, and steering-box location. Verify clearance before final installation. |
| Does the power steering pump need to match the box? | Yes. Pump pressure, flow, fittings, pulley speed, and reservoir capacity affect steering operation. A mismatched pump can cause heavy steering, excessive sensitivity, noise, heat, leaks, or poor return-to-center characteristics. |
| Can the same pump operate power steering and HydraStop? | A properly configured pump can support both systems. The pump must provide the required flow and pressure, and the hoses must be routed correctly through the hydraulic brake-assist unit and steering box. |
| Should I buy a gearbox or a complete power steering kit? |
Buy the individual gearbox when the vehicle already has compatible hydraulic, steering-shaft, and linkage components. Choose a complete kit when converting from manual steering or when several existing components are worn, missing, or incompatible. |
| Do I need a front-end alignment after installation? | An alignment is recommended after steering-box, linkage, suspension, or ride-height changes. The installer should also verify that the steering wheel is centered and that the gearbox reaches its intended travel without binding. |
