2003–2006 (2007 Classic) Silverado/Sierra 2WD Crew Cab Complete 2" Front / 4" Rear Lowering Kit with Shocks

Upgrade Your Silverado or Sierra with a Perfect Drop and Premium Ride Quality

If you own a 2003, 2004, 2005, or 2006 Chevrolet Silverado or GMC Sierra 2WD Crew Cab, or the 2007 Classic, you know these trucks were built for durability, utility, and style. But factory ride height leaves a big gap between fender and tire—something most custom truck enthusiasts can’t stand.

This 2" Front / 4" Rear Lowering Kit with Shocks was engineered specifically for your GM Crew Cab. Designed for trucks with factory leaf spring hangers welded to the frame, it provides a precise stance, smooth ride quality, and reliable components. With a 2-inch front drop via coil springs and a 4-inch rear drop via axle flip and hanger/shackle system, this kit balances aggressive looks with everyday drivability.

FITMENT NOTES:

Note: For crew cab trucks with factory leaf spring hangers welded to frame.

What’s Included in the 2/4 Lowering Kit?

This isn’t a piecemeal suspension package—it’s a complete lowering solution with all the parts you need to get your stance right the first time.

Front Components: 2-Inch Drop Coil Springs

• Precision-engineered lowering coil springs designed for the weight of Silverado/Sierra Crew Cab models.

• Maintains alignment geometry while lowering ride height.

• Heavy-duty spring steel construction for long-lasting performance.

Rear Components: Axle Flip + Hanger & Shackle Setup

• Axle Flip Kit moves the rear axle from below the leaf springs to above, providing a dramatic drop.

• New Rear Shackle Hangers + Longer Shackles bring the rear back up slightly for a net 4-inch drop.

• Pinion angle adjusting brackets included to maintain proper drivetrain geometry.

• Heavy-duty U-bolts, spring plates, and all hardware included for a secure installation.

Shocks: Tuned for Lowered Applications

This kit includes performance shocks designed specifically for lowered ride height, ensuring improved handling without sacrificing comfort.

• Front Shock #1415

• Rear Driver’s Shock #1900

• Rear Passenger’s Shock #2000

With this setup, you get not only the drop but also the ride quality and handling improvements your truck deserves.

Why Choose a 2/4 Drop for Your Silverado or Sierra?

The 2-inch front / 4-inch rear drop is one of the most popular configurations for GM trucks because it delivers:

1. Balanced, Aggressive Stance

   • Reduces wheel gap for a sleeker, custom look.

   • Provides a mild rake that enhances body lines.

2. Improved Handling and Control

   • Lower center of gravity reduces body roll in corners.

   • Suspension feels tighter and more responsive on highways.

3. Better Ride Quality than Extreme Drops

   • 2/4 is low enough to stand out but not so low that ride quality suffers.

   • Shocks tuned for lowered stance keep comfort intact.

4. Show and Street Ready

   • Great for daily driving, weekend cruises, and car shows.

   • Works perfectly with aftermarket wheels and tires (20–24” recommended).

Kit Design for Welded Factory Leaf Spring Hangers

Many GM trucks from this era were manufactured with factory leaf spring hangers welded directly to the frame, which makes installation trickier if you don’t have the right kit.

This 2/4 lowering kit is designed specifically for these trucks:

• Includes new rear shackle hangers that bolt in properly.

• Corrects rear axle geometry with pinion angle brackets.

• Ensures your driveshaft, U-joints, and suspension angles remain in safe operating ranges.

By choosing the right kit for your truck’s frame setup, you avoid issues like vibration, uneven tire wear, or poor ride quality.

Installation Overview

While professional installation is recommended for best results, experienced enthusiasts can install this kit with basic tools and mechanical knowledge.

1. Front Coil Spring Installation

   • Remove factory coil springs.

   • Replace with engineered 2-inch drop springs.

   • Retains factory-style mounting for straightforward install.

2. Rear Axle Flip & Hanger/Shackle Install

   • Unbolt axle and move it to top of leaf springs.

   • Install new shackle hangers and longer shackles.

   • Secure with included hardware, U-bolts, and spring plates.

   • Add pinion angle brackets to ensure proper drivetrain alignment.

3. Shock Replacement

   • Bolt in included lowered shocks at front and rear.

   • Designed to handle reduced travel of lowered suspension.

4. Final Alignment & Torque

   • Always torque bolts to spec.

   • Alignment highly recommended after installation.

Ride Quality & Performance

One of the most common fears when lowering a truck is a harsh, bouncy ride. This kit is engineered to provide:

• Smooth Ride Comfort – Comparable to stock suspension for daily driving.

• Improved Handling – Reduced body roll and tighter steering response.

• Maintained Utility – Still capable of hauling and towing within rated limits.

Matched shocks (#1415, #1900, #2000) are the key—keeping suspension travel controlled and eliminating bottoming out.
