CPP TIE RODS FOR CLASSIC CARS AND TRUCKS

MODERN STEERING CONTROL IN A BOLT-ON, APPLICATION-SPECIFIC PACKAGE
 
Upgrade your classic car or truck with a CPP power steering box designed to provide easier low-speed steering, improved road feel, quicker response, and more confident control. CPP offers power steering gearboxes for a wide range of classic Chevrolet, Ford, Dodge, Mopar, GM, and custom vehicle applications. Available options include compact manual-to-power conversions, direct-fit replacement boxes, modern performance gearboxes, and complete conversion kits. Whether you are restoring a comfortable cruiser, improving a daily-driven classic, or building a performance-oriented street machine, CPP can help you find a steering box that fits the vehicle and the way you want it to drive.
 
A power steering box, also called a power steering gearbox or steering gear, converts steering-wheel movement into the mechanical motion that moves the vehicle’s steering linkage. Hydraulic pressure from the power steering pump assists the internal movement of the gearbox, reducing the effort required to turn the wheels. This is especially helpful during parking, low-speed maneuvering, and driving vehicles equipped with wider modern tires.
 
 WHY UPGRADE YOUR CLASSIC VEHICLE’S STEERING BOX?
 
Original manual and early power steering systems were designed around narrow tires, factory suspension geometry, and the driving expectations of their time. Decades of wear can also create excessive play, inconsistent response, fluid leaks, and a loose feeling at the steering wheel. Replacing an outdated or worn steering box can make a noticeable difference in how the vehicle feels from the driver’s seat.
 
LESS EFFORT AT LOW SPEEDS: Power assistance makes it easier to turn the wheels while parking, navigating a crowded event, or maneuvering inside a garage.
 
IMPROVED STEERING RESPONSE: Modern steering ratios and internal components can provide a more direct connection between steering-wheel input and vehicle movement.
 
BETTER HIGHWAY STABILITY: Improved internal control can reduce unwanted steering movement and help the vehicle feel more settled at cruising speeds.
 
GREATER DRIVER CONFIDENCE: A tighter and more predictable steering system makes a classic car or truck more enjoyable to drive in modern traffic.
 
SUPPORT FOR COMPLETE VEHICLE UPGRADES: A power steering box can complement other improvements such as tubular control arms, modern brakes, sway bars, coilovers, upgraded steering linkage, and wider performance tires.

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:

  • Year
  • Make
  • Model
  • Two-wheel-drive or four-wheel-drive configuration
  • Factory manual or power steering system
Use the CPP Part Finder
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:

  • Factory manual steering
  • Factory power steering
  • A previously installed conversion
  • An aftermarket steering column
  • A stock column that has already been modified
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:

  • Original or aftermarket column
  • Tilt or non-tilt
  • Column shift or floor shift
  • Round splined shaft or Double-D shaft
  • Shaft diameter and spline count
  • Collapsible shaft or solid column design
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:

  • Sector-shaft diameter
  • Spline count
  • Master-spline location
  • Pitman-arm length
  • Standard or reverse taper
  • Manual or power steering design

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:

  • Inverted-flare fittings
  • O-ring fittings
  • Metric fittings
  • Application-specific adapters
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:

  • Headers or exhaust manifolds
  • Engine mounts
  • Clutch linkage or factory Z-bar
  • Radiator
  • Frame rails
  • Suspension components
  • Steering shaft
  • Oil pan and accessory drive
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:

  • Power steering pump
  • Pump bracket
  • Pump pulley
  • Pressure and return hoses
  • Pitman arm
  • Rag joint
  • Steering shaft
  • Mounting brackets
  • Center link or drag link
  • Idler arm
  • Steering linkage components
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

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.
Important Installation Notice Always follow the instructions supplied with the specific CPP part number. Steering components are safety-critical and must be installed with the correct hardware, torque specifications, steering-shaft engagement, and component clearance.

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.
