Deciding whether to use upper control arms (UCAs) as part of a lift kit depends on several factors, including the type of lift you're planning, the vehicle you have, and your specific driving needs. Let's explore the considerations that can help you make an informed decision:
1. Lift Height:
The amount of lift you're aiming for plays a significant role. In general, if you're going for a moderate lift (1-2 inches), your stock upper control arms might be able to accommodate the changes without major issues. However, if you're planning a larger lift (2+ inches), upgrading to aftermarket upper control arms could be beneficial.
2. Alignment Adjustment:
Lifting a vehicle can often alter its suspension geometry and affect alignment settings. Aftermarket upper control arms are designed with adjustable ball joints or bushings, allowing you to fine-tune your vehicle's alignment after the lift. This helps maintain proper tire wear, steering response, and handling characteristics.
3. Suspension Travel and Articulation:
If your vehicle sees off-road use or requires increased suspension travel, aftermarket UCAs can offer improved articulation. They provide extra clearance for larger tires and better control over wheel movement during off-road adventures.
4. Increased Strength:
Aftermarket upper control arms are typically built with stronger materials and more robust designs compared to stock components. This increased strength can handle the additional stress that comes with lifting your vehicle, especially if you're using larger tires or subjecting it to demanding terrain.
5. Cost and Budget:
Upgrading to aftermarket upper control arms can add to the overall cost of your lift kit. Consider your budget and whether the benefits they provide align with your needs and driving style.
6. Manufacturer Recommendations:
If you're planning to install a lift kit, check the recommendations of the lift kit manufacturer. Some lift kits might include upgraded UCAs as part of the package, while others might provide guidelines for using stock components.
7. Professional Installation:
Regardless of your decision, it's important to have any lift kit components, including upper control arms, installed by professionals who understand the intricacies of suspension systems and proper alignment procedures.

8. Long-Term Goals:
Consider your long-term plans for the vehicle. If you anticipate further modifications or more aggressive driving, investing in aftermarket UCAs now could save you from needing to upgrade again later.
In summary, while using upper control arms in a lift kit can offer benefits such as improved alignment adjustability, increased suspension travel, and enhanced strength, it's essential to evaluate your specific lift height, driving style, and vehicle type. If you're planning a substantial lift, off-road adventures, or precision alignment adjustments, upgrading to aftermarket upper control arms could be a wise choice. However, if you're opting for a smaller lift and your driving needs are more casual, your stock upper control arms might suffice. Consulting with suspension experts or your lift kit manufacturer can provide valuable insights tailored to your situation.
