Chevy Silverado / GMC Sierra 2WD Crew Cab – 2" Front / 4" Rear Complete Lowering Kit with Shocks
For Crew Cab trucks with factory leaf spring hangers welded to the frame
Your Silverado or Sierra Crew Cab is built for strength, versatility, and daily dependability—but the factory suspension tends to leave these GMT800 trucks with excessive wheel gap, a tall rear rake, and handling that feels more like a work truck than a performance street machine. If your goal is to enhance the stance, improve cornering, and give your truck a cleaner, more controlled ride without sacrificing drivability, this DJM 2-inch front / 4-inch rear lowering kit with shocks is the ideal upgrade.
Designed specially for 2003–2006 and 2007 Classic Silverado/Sierra 2WD Crew Cab models equipped with welded factory leaf spring hangers, this complete lowering package provides a true leveled appearance, improves highway stability, and gives your truck a smooth lowered stance that complements any wheel and tire setup—from OEM 17-inch wheels to upgraded 20s, 22s, and more.
This is not a pieced-together drop. It’s a fully engineered system designed to preserve OEM geometry while offering a more refined, street-ready suspension feel.
Engineered 2-Inch Front Drop Using Precision Lowering Coil Springs
Unlike generic lowering springs that compromise suspension geometry and ride comfort, the front of this kit uses engineered DJM coil springs tuned specifically for the weight and dynamics of the Crew Cab platform.
Why Engineered Lowering Springs Matter
Crew Cab trucks carry more weight over the front end than regular or extended cab models. Using springs designed for lighter trucks can result in:
-
Harsh ride quality
-
Coil binding
-
Inconsistent ride height
-
Uneven settling
-
Steering instability
DJM eliminates these issues by manufacturing purpose-built 2” lowering coils that maintain proper spring rate, balance, and compression characteristics.
Key Benefits of DJM 2-Inch Front Coil Springs
✔ Consistent, true-to-spec 2-inch drop
✔ Maintains OEM spring travel and comfort
✔ Eliminates excessive bounce from cut coils
✔ Improves steering response
✔ Optimized spring compression for Crew Cab weight
These springs produce a cleaner stance, improved stability, and a refined feel, making your Silverado or Sierra more enjoyable to drive whether you're commuting, cruising, or hauling light loads.
Rear Suspension: 4-Inch Drop Using Axle Flip + Lift-Correction Shackles and Hangers
The rear of the truck is lowered using a time-tested and performance-proven combination: a DJM axle flip kit paired with new rear shackle hangers and longer shackles. This approach achieves a deep drop without sacrificing ride quality or suspension travel.
How It Works
A standard axle flip kit typically lowers the rear 6 inches, which is too much for a balanced 2/4 drop and can negatively impact drivability. To solve this, DJM includes:
-
New shackle hangers
-
Longer DJM shackles
These components raise the rear back up after the flip, creating a perfect 4” total drop that aligns beautifully with the 2-inch front.
What’s Included in the Rear Drop System
-
Axle flip brackets
-
Replacement rear shackle hangers
-
Longer lowering shackles
-
Pinion angle adjustment brackets
-
High-strength U-bolts
-
Spring plates
-
All installation hardware
This engineered combination creates a visually aggressive stance while keeping the leaf springs operating within their ideal range. The rear end remains predictable, stable, and capable of handling factory-rated loads within reason.
Pinion Angle Correction for Vibration-Free Driving
A major consideration when lowering any rear-wheel-drive truck is the driveshaft angle. Lowering changes how the pinion aligns with the transmission output shaft, which can cause:
-
Highway vibration
-
Driveline wear
-
U-joint stress
-
Reduced acceleration smoothness
To eliminate these issues, DJM includes pinion-adjusting axle brackets, allowing you to restore proper angle alignment during installation. This ensures:
✔ A smooth ride with no driveline vibration
✔ Proper universal joint operation
✔ Optimized power transfer
✔ Long-term drivetrain reliability
This is a critical feature many cheaper lowering kits overlook—and it makes a major difference in the driving experience.
Shocks Included – Tuned Specifically for Lowered GM Crew Cab Trucks
Lowered suspension requires specialized shock absorbers to maintain proper damping, prevent harsh bottoming out, and keep handling consistent. DJM includes the exact shocks engineered for this drop:
Included DJM Shock Package
-
Front Shocks: DJM 1415
-
Rear Driver Shock: DJM 1900
-
Rear Passenger Shock: DJM 2000
These shocks are valved to match the suspension geometry of the lowered GMT800 platform.
Benefits of DJM's Lowering Shocks
✔ Improved ride comfort & damping control
✔ Reduces bounce commonly found with stock shocks after lowering
✔ Ensures full suspension travel without bottoming out
✔ Enhances highway stability and cornering precision
✔ Maintains safe shock travel after axle flip modification
With these shocks installed, your truck feels planted, predictable, and much sportier—without losing everyday comfort.
Ride Quality: What You Can Expect After Installation
A 2-inch front / 4-inch rear drop dramatically changes how your Silverado or Sierra handles. By lowering the center of gravity and optimizing suspension geometry, you’ll experience:
✔ Sharper cornering & reduced body roll
The truck feels more agile and composed through turns.
✔ Better braking control
Less nose dive and more stable deceleration.
✔ A smoother, more controlled ride
The engineered springs and shocks work together to soften harsh road impacts.
✔ A cleaner, more aggressive stance
The unsightly factory rake is gone, replaced by a balanced, modern profile.
✔ Improved performance feel
Your truck will feel more responsive, precise, and enjoyable to drive.
This is the ideal drop for daily drivers, weekend cruisers, or show builds wanting a clean look without radical suspension changes.
