1. Lowering Springs:
* How it works: This is the most common and generally easiest method. You replace the factory springs with shorter, lower-rate springs designed for lowering.
* Pros: Relatively inexpensive, straightforward installation (if you're mechanically inclined), good ride quality if you choose springs designed for a balance between lowering and comfort.
* Cons: Can reduce ground clearance significantly. May affect ride quality negatively if you choose overly aggressive lowering springs. May require adjusting or replacing other suspension components (such as shocks/struts) for optimal performance.
* Installation: Requires basic mechanical skills, jack stands, wrenches, and possibly spring compressors (highly recommended for safety).
2. Spindles:
* How it works: These are replacement components that bolt onto your existing suspension, effectively lowering the height of the control arms.
* Pros: Offers a more significant drop than lowering springs alone, often allowing for a more aggressive stance.
* Cons: More expensive than lowering springs. Can affect camber (wheel angle), potentially causing tire wear. May require further adjustments (alignment). Often requires more advanced mechanical skill.
* Installation: Requires a good understanding of suspension geometry and alignment.
3. Drop Shocks/Struts:
* How it works: These are shorter shocks/struts designed to work with a lowered suspension. They don't lower the truck on their own but are necessary to prevent damage to the suspension components.
* Pros: Improves the handling and ride quality, especially when paired with lowering springs or spindles.
* Cons: Should be only used in conjunction with other lowering methods. Can reduce suspension travel if too short.
* Installation: Straightforward once other lowering components are installed.
4. Combination Approach:
Many people combine lowering springs and spindles for a more dramatic drop. This often requires additional modifications, potentially including different control arms, shocks, and even modifications to the steering components.
Important Considerations:
* Ride Height: Decide how much you want to lower the truck. Excessive lowering can negatively impact ride quality, handling, and potentially cause damage to other components.
* Alignment: After any lowering modification, a professional wheel alignment is crucial to ensure proper tire wear and safe handling.
* Brakes: Lowering the front end might interfere with brake lines, necessitating adjustments or replacement.
* Bump Stops: You'll likely need shorter bump stops to prevent the suspension from bottoming out after lowering.
* Safety: Work safely. Use jack stands, proper tools, and follow all safety precautions. If you're not comfortable working on your vehicle yourself, take it to a qualified mechanic or suspension shop.
Recommendation:
For a beginner, starting with lowering springs is the best approach. Research reputable brands offering springs specifically for your 1984 Chevy Silverado to ensure proper fit and quality. Always prioritize safety and consult with experienced mechanics if you have any doubts about your capabilities.
