4-Inch Rear Lowering Kit (Hanger & Shackle System)

Achieve the perfect lowered stance on your long bed GM truck with this 1999–2006 Chevy Silverado & GMC Sierra 2WD Long Bed 4-Inch Rear Lowering Kit. Designed specifically for long bed two-wheel-drive models, this rear suspension upgrade delivers a true 4-inch rear drop by relocating both ends of the leaf spring closer to the frame—without sacrificing ride quality, reliability, or everyday drivability.

If you want more drop than a basic shackle provides, this kit is the ideal solution. By combining a rear leaf spring hanger and shackle system, you gain additional lowering capability while maintaining proper suspension geometry and smooth rear suspension operation. The result is a clean, aggressive stance that looks right and drives right.

Why a 4-Inch Rear Drop Is the Ideal Choice

A 4-inch rear drop is one of the most popular lowering options for Silverado and Sierra owners because it strikes the perfect balance between visual impact and street-friendly performance.

Benefits of a 4-Inch Rear Drop

• Eliminates excessive factory rake

• Levels the truck when paired with a lowered front

• Improves overall stance and appearance

• Enhances wheel and tire fitment

• Maintains suspension comfort for daily driving

• Avoids overly aggressive geometry changes

This setup delivers a noticeable, aggressive look while remaining practical for everyday use.

How This Rear Hanger & Shackle System Works

This lowering kit achieves a total of 4 inches of rear drop by relocating both ends of the factory leaf spring upward toward the frame.

Suspension Geometry Explained

• The rear shackle moves the back of the leaf spring upward

• The leaf spring hanger relocates the front mounting point upward

• Each end of the leaf spring is moved 2 inches closer to the frame

• Combined, this results in a true 4-inch rear drop

Because the factory leaf springs remain in place, the suspension retains much of its original ride quality and load-handling characteristics.

---

Why Add the Leaf Spring Hanger?

Many rear drop setups rely only on shackles, which typically provide a mild drop. If you want more lowering without harsh ride quality, adding the leaf spring hanger is the correct approach.

Advantages Over Shackle-Only Kits

• More total drop without compromising ride

• Better axle positioning

• Maintains suspension articulation

• Reduces axle wrap compared to more aggressive methods

• Cleaner stance on long bed trucks

This makes the kit ideal for truck owners who want a deeper drop done the right way.

Ride Quality That Matches the Look

Lowering your truck shouldn’t mean living with a stiff, uncomfortable ride. This rear hanger and shackle system is engineered to maintain smooth suspension travel, even with the truck sitting lower.

What You’ll Notice on the Road

• Improved rear-end stability

• Reduced body roll

• Better highway control

• Smoother ride over uneven pavement

• Balanced feel when paired with a front drop

For daily-driven long bed trucks, this is a major advantage over harsher lowering methods.

---

Perfect for Daily Drivers, Street Builds & Show Trucks

This 4-inch rear lowering kit is versatile enough to work with a wide range of build styles, including:

• Daily-driven Silverados and Sierras

• Clean street trucks

• Audio and show builds

• OEM-plus style builds

• Custom wheel and tire setups

Whether your truck sees commuting duty, weekend cruising, or show appearances, this kit provides the right combination of stance, comfort, and reliability.

Shock Information – Shocks NOT Included (Important)

Shocks are NOT included with this rear lowering kit.

Because lowering the rear suspension reduces available shock travel, proper shock length is critical for ride quality and suspension performance.

DJM Recommended Rear Shocks

For best performance, DJM recommends the following shocks (sold separately):

• Rear Driver Side Shock: 1900

• Rear Passenger Side Shock: 2000

These shocks are sized correctly for a lowered rear suspension and help ensure:

• Proper suspension travel

• Controlled damping

• Reduced harshness

• Prevention of shock bottoming or topping out

• Extended shock life

Important: Using factory-length or incorrect shocks may result in poor ride quality and premature shock failure.

---

NOTE: Factory Rear Shock Mount Configuration

Your factory rear shock mounts are staggered, with:

• One shock mounted in front of the rear axle

• One shock mounted behind the rear axle

This staggered configuration is normal for these trucks and is the reason different shock part numbers are required for the driver and passenger sides. The recommended DJM shocks account for this design to ensure proper fitment and performance.

---

Why Proper Shocks Matter on a Lowered Long Bed Truck

Lowering a long bed truck changes suspension dynamics more than many owners realize. Proper shocks are essential to control:

• Axle movement

• Suspension rebound

• Ride comfort

• Stability under load

• Overall handling performance

Matched shocks allow the suspension to operate within its designed range, keeping your lowered truck comfortable, controlled, and safe.

---

Heavy-Duty Construction for Long-Term Reliability

This rear lowering kit is built using high-strength steel components designed to handle the demands of long bed trucks.

Construction Highlights

• Heavy-duty steel hangers and shackles

• Precision-engineered mounting points

• Durable, corrosion-resistant finish

• Designed for real-world driving conditions

These components are built to last, making this kit a reliable choice for long-term use.

This kit is designed to install using factory mounting locations, making it a straightforward upgrade for professional installers or experienced DIY builders.

Installation Notes

• Fits 2WD long bed trucks only

---

Pairing With a Lowered Front Suspension

Most long bed Silverado and Sierra owners pair this rear kit with a front lowering setup to achieve a level stance.

Popular front drop combinations include:

• 2-inch front lowering kits
