Methods for Lowering a 1987 Chevy Silverado:
* Lowering Springs: This is the most common and often least expensive method. New springs with a lower spring rate are installed, reducing the vehicle's ride height. This is a relatively straightforward job if you're comfortable with basic wrenching, but requires spring compressors for safety. You'll likely need new shocks to match the lower ride height. Consider these factors:
* Drop Height: Springs come in various drop heights (e.g., 2/3 drop, 2/4 drop, 3/4 drop, etc.), indicating the amount of drop in the front and rear. A 2/4 drop means 2 inches in the front and 4 inches in the rear.
* Ride Quality: Lowering springs generally result in a firmer ride.
* Cost: Relatively inexpensive compared to other methods.
* Lowering Blocks (Rear Only): These are simple blocks of metal that are inserted between the axle and the leaf springs in the rear. They're easy to install but can negatively impact ride quality and handling, especially with larger drops. Generally not recommended for significant drops.
* C-Notch (Rear Only): This involves cutting and modifying the rear frame to allow for more axle travel and a lower stance without limiting suspension articulation. This is more involved and requires welding skills or a professional shop.
* Air Suspension: This allows for adjustable ride height and a smoother ride. It's the most expensive option, requiring a complete air suspension system including compressors, tanks, and control valves. This is a complex installation generally best left to professionals.
* Combination of Methods: Often, people combine lowering springs with lowering blocks (rear) to achieve their desired drop. This is common but again, carefully consider ride quality and handling implications.
Before You Begin:
* Research: Research specific lowering kits for your 1987 Chevy Silverado's model and configuration (e.g., 2WD, 4WD, short bed, long bed). This will ensure compatibility and proper fitment.
* Tools: Gather the necessary tools, including wrenches, sockets, jack stands, spring compressors (for springs), and potentially a welder (if C-notching).
* Alignment: After lowering your truck, you must get a wheel alignment. Lowering changes the suspension geometry, and an alignment is crucial for safe driving and tire wear.
Professional Installation:
If you're not comfortable working on your vehicle, or if you're planning a more complex lowering method (like a C-notch or air suspension), it's highly recommended to take your truck to a qualified mechanic or suspension shop. They have the expertise and tools to do the job safely and correctly.
In short, lowering your 1987 Chevy Silverado can dramatically change its appearance, but it's essential to choose the right method and ensure proper installation to maintain safety and handling. Research thoroughly and prioritize safety.
