HOW TO CHOOSE THE RIGHT CPP SPINDLES
| Selection Step | What to Consider |
|---|---|
|
1
Start With the Vehicle Application
|
Identify the exact year, make and model. Similar-looking spindles may use different ball-joint tapers, steering arms, bearings, hubs, tie-rod locations or brake brackets. Do not select a spindle based only on appearance or general vehicle family. |
|
2
Choose Your Ride Height
|
Decide whether you want to:
Final ride height is affected by the spindle, springs, control arms, tire diameter and overall vehicle weight. |
|
3
Identify the Brake System
|
The spindle must match the brake package you plan to use. Confirm:
A spindle designed for one brake system may not accept another rotor or caliper without the correct CPP brackets and components. |
|
4
Check the Wheel Bolt Pattern
|
The spindle itself may not determine the final bolt pattern, but the matching hub or rotor will. CPP offers spindle systems supporting several common patterns, including 5-lug and 6-lug truck configurations. Mustang II CS Series options are also available in several bolt-pattern combinations. |
|
5
Choose a Bearing or Sealed-Hub System
|
Traditional spindles normally use serviceable inner and outer wheel bearings. CPP CS Series and selected X10 systems use modern sealed-hub assemblies. Choose the system that best fits your:
|
|
6
Verify Steering and Suspension Components
|
Before ordering, determine whether the spindle requires specific:
Some CPP truck spindle packages include conversion ball joints, tie rods and sleeves, while other products are sold as spindles only. |
|
7
Check Wheel and Tire Clearance
|
Drop spindles and large brake systems can affect clearance between the wheel and:
Always verify the minimum wheel diameter for the complete brake and spindle package. |

CPP SPINDLE INSTALLATION OVERVIEW
- Confirm that all components match the vehicle and brake package.
- Inspect the control arms, ball joints and tie rods.
- Compare the new spindle with the original component.
- Verify the steering-arm and caliper-bracket orientation.
- Test-fit the rotor, hub and caliper.

Frequently Asked Questions
| Question | Answer |
|---|---|
| How much do CPP drop spindles lower a vehicle? | Many CPP car drop spindles lower the front approximately 2 inches. Many CPP C10 truck drop spindles provide approximately 2.5 inches of lowering. The exact drop depends on the application and part number. |
| Will drop spindles change the ride quality? | Drop spindles lower the wheel mounting position without requiring an equally large reduction in spring height. This can help retain more suspension travel than achieving the same drop with extremely short springs. Final ride quality still depends on the springs, shocks, control arms, alignment, tires and vehicle weight. |
| Can I use my existing brakes with new spindles? | Only when the spindle is designed for those brake components. Rotor, caliper, bracket, bearing and hub compatibility must all be verified. Some CPP spindles are designed for specific D52, D154, Wilwood or Corvette-style brake systems. |
| Do CPP spindles include hubs? | Some do and some do not. CPP CS Series spindle kits generally include sealed C7-style hubs, while many traditional spindle products use separate hubs, rotors and wheel bearings. Check the individual product description before ordering. |
| What is the benefit of a sealed hub? | A sealed hub combines the wheel-bearing assembly into a preassembled unit. CPP’s C7-style double-row hub design is intended to increase rigidity and load capacity while reducing spindle flex and maintenance compared with a traditional tapered-bearing spindle pin. |
| What is a modular spindle? | A modular spindle uses interchangeable or application-specific caliper brackets so the spindle can support different brake configurations. The exact combinations depend on the vehicle and CPP brake package. |
| Do I need new ball joints or tie rods? | Not always. Some spindle conversions reuse the original-style suspension connections, while others require different ball joints, outer tie rods, sleeves or taper adapters. Certain CPP C10 packages include the required conversion components. |
| Will I need a front-end alignment? | Yes. Any time a spindle, ball joint, tie rod or control-arm component is replaced, the front suspension should be aligned before normal driving. |
| How do I know whether my spindles need replacement? | Inspect the spindle and bearing surfaces for scoring, wear, heat damage, cracks or damaged threads. Grinding, chattering or roughness while the wheel rotates may also indicate a bearing or spindle problem that requires inspection. CPP recommends replacement when the bearing surfaces no longer allow the bearings to operate smoothly. |
