Lowering your 1999-2006 Chevrolet Silverado can dramatically improve its stance and handling, giving it a customized look that stands out from the crowd. A 4/6 drop kit achieves this by lowering the front end by 4 inches and the rear by 6 inches, resulting in a raked, aggressive appearance. However, choosing the right kit and understanding the implications are crucial for a successful and safe modification. This guide will delve into the details of 4/6 drop kits for your Silverado, addressing common questions and concerns.
What is a 4/6 Drop Kit?
A 4/6 drop kit is a suspension modification package designed to lower your truck's ride height. The "4/6" refers to the amount of drop achieved: 4 inches in the front and 6 inches in the rear. This specific configuration creates a noticeably lower profile, enhancing the truck's aesthetic appeal. The kit typically includes components for both the front and rear suspension systems, allowing for a balanced and controlled drop.
What Components are Included in a Typical 4/6 Drop Kit?
Most 4/6 drop kits for 99-06 Silverados include:
- Lowering spindles (front): These replace the stock spindles, effectively lowering the front suspension.
- Lowering blocks or shackles (rear): These either replace the existing blocks under the axle or the shackles connecting the leaf springs, lowering the rear suspension.
- New shocks or struts: Often, the kit will include shocks or struts that are designed for the lowered ride height to maintain proper suspension travel and prevent bottoming out. Sometimes, these are sold separately.
- Hardware: All necessary bolts, nuts, and washers for installation.
How Much Does a 4/6 Drop Kit Cost?
The cost of a 4/6 drop kit for a 1999-2006 Silverado can vary depending on the brand, quality of components, and included parts. You can expect to pay anywhere from a few hundred dollars to over a thousand dollars for a complete kit. Remember that installation costs are separate and should be factored into your budget.
What are the Pros and Cons of a 4/6 Drop?
Pros:
- Improved aesthetics: The lowered stance significantly enhances the truck's appearance, giving it a more aggressive and customized look.
- Improved handling (potentially): A lower center of gravity can lead to improved handling in some cases, though this depends on other factors like tire choice and driving style.
- Better aerodynamics (slightly): A lower profile can slightly reduce aerodynamic drag, improving fuel efficiency.
Cons:
- Reduced ground clearance: This is a major drawback. You'll need to be more careful when driving over bumps, dips, and inclines to avoid scraping the undercarriage.
- Potential rubbing issues: Lowering the truck can cause tire rubbing against the fenders or other parts of the body, requiring modifications like fender rolling or different wheels and tires.
- Ride quality changes: The ride quality can be harsher than stock due to reduced suspension travel. The type of shocks included in your kit will greatly affect this.
- Increased stress on suspension components: The lowered suspension can experience increased stress, potentially leading to premature wear.
Will a 4/6 Drop Affect My Truck's Reliability?
A properly installed 4/6 drop kit shouldn't significantly affect your truck's reliability if you maintain it properly. However, the increased stress on suspension components mentioned above means that regular inspections and maintenance are more crucial than ever.
What Kind of Tires Should I Use with a 4/6 Drop?
Selecting the right tires is essential to avoid rubbing issues. Smaller diameter wheels and tires with a lower profile are typically necessary. You may need to consult a tire professional or online forums to determine the appropriate tire size for your specific setup.
Is Installing a 4/6 Drop Kit Difficult?
Installing a 4/6 drop kit is a moderately complex project that typically requires mechanical experience and the right tools. While some individuals attempt DIY installation, it's often recommended to have a professional mechanic perform the installation to ensure proper alignment and to avoid potential damage.
Do I Need an Alignment After Installing a 4/6 Drop Kit?
Yes, a wheel alignment is absolutely necessary after installing a 4/6 drop kit. Lowering your truck significantly alters the suspension geometry, and failing to get an alignment can lead to uneven tire wear, poor handling, and potential safety hazards.
This guide provides a comprehensive overview of 4/6 drop kits for 1999-2006 Chevrolet Silverados. Remember to always research thoroughly and choose reputable brands for your parts. Careful planning and professional installation are key to ensuring a successful and safe modification.
