2007-2018 Chevy/GMC Silverado/Sierra 1500 – 4 Inch Rear Lowering Kit
Ultimate Rear Drop Solution for Control, Style, and Ride Quality

If you're looking to add that perfect balance of aggressive stance and smooth ride quality to your 2007-2018 Chevy Silverado 1500 or GMC Sierra 1500, the 4 Inch Rear Lowering Kit from DJM Suspension is exactly what your truck needs. Designed to move the axle from beneath the leaf spring to the top of the leaf spring (“axle flip”), this kit delivers a clean and reliable 4” rear drop without cutting corners—or sacrificing comfort.

Precision-Engineered Rear Drop: How It Works

On the Silverado and Sierra 1500, GM welded the forward leaf spring hanger directly to the frame, which prevents a conventional hanger change. To offer a safe, high-quality alternative, DJM engineered a system that flips the axle and repositions the suspension geometry:

• The axle is moved to the top of the leaf spring.

• Then the shackle hanger is inverted and paired with a longer shackle, which allows the end of the leaf to move into the correct arc as the suspension cycles.

• You can choose between different shackle mounting holes to achieve either a 4-inch or 5-inch drop, depending on how aggressive you want the stance to be.

• The kit includes exclusive pinion-adjustable axle brackets, allowing you to dial in your pinion angle for optimal driveline alignment and zero vibration.

This isn’t a “one size fits all” approach—DJM has studied these trucks and figured out how to safely lower the rear while still maintaining factory alignment specs, suspension travel, and towing capabilities.

This is the same proven design trusted by thousands of Silverado and Sierra owners, and ideal for daily driving, weekend show cruising, or even mild towing when paired with the recommended shock setup.

Why This Rear Lowering Kit Outperforms the Competition

Lowering a late-model Silverado or Sierra isn’t as simple as “moving parts around.” With GM’s frame-mounted spring hanger and limited driveline clearance, you need a precision-engineered solution that keeps the truck safe and functional. DJM’s kit succeeds for the following reasons:

 Maintains Factory Ride Quality

Because the leaf spring is not re-arched or cut, your suspension keeps its factory spring rate. That means less bottoming-out, more comfort on rough roads, and preserved load capacity (especially when supported with DJM shocks).

 Corrects Pinion Angle for Vibration-Free Driving

DJM’s included pinion adjustable brackets are a major advantage over cheap flip kits. Once the axle is repositioned, the driveline angle changes — but with adjustable brackets, you can dial it back into perfect alignment (no more buzzing or humming at highway speeds).

 Fully Bolt-On Installation

No welding or frame cutting is required. The kit bolts directly to the frame using supplied hardware, making it a safer and clean installation for both DIYers and professional shops.

 Two Drop Height Options in One Kit

Whether you want a conservative 4” or more aggressive 5” drop, this kit has you covered. You simply choose the appropriate shackle mounting hole during installation.

Application Fitment

This kit fits the following vehicles:

• 2007-2018 Chevrolet Silverado 1500 (2WD / RWD only)

• 2007-2018 GMC Sierra 1500 (2WD / RWD only)

It does not fit heavy-duty 2500HD/3500HD or 4WD models.

Suggested Complementary Products

To complete your rear drop and maintain a controlled ride, we strongly recommend adding the following DJM components:

• Rear Shock 2100 (Sold Each) – specifically valved for lowered Silverado/Sierra

• DJM Front Lowering Control Arms – Ideal if you plan a complete 4/7 drop in combination with this flip kit

• Rear Shock Extenders – If you plan on using OEM shocks temporarily, extenders help keep the operating angle correct
  
  

Installation Tips & Best Practices

When lowering the rear of a Silverado 1500, proper preparation is key. Below are a few pro tips to make your install smooth and trouble-free:

✔ Use Jack Stands on a Solid Surface
Support the rear frame securely before unbolting the leaf spring u-bolts.

✔ Test-Fit Components Before Final Torque
Position axle flip brackets and shackles finger-tight, cycle the suspension, then torque everything once you’re satisfied with clearance and alignment.

✔ Set Pinion Angle With Weight on the Suspension
After the truck is back on the ground, use an angle finder to adjust pinion angle via the supplied brackets. Proper pinion alignment prevents vibration and premature u-joint wear.

✔ Upgrade Rear Shocks
Factory shocks were not designed for the shorter suspension travel. The DJM 2100 Rear Shocks are valved specifically for lowered applications and help eliminate bounce and instability.

Performance Meets Style: Benefits of Lowering Your Truck

Lowering the rear of your Silverado/Sierra is about more than just appearance. Here are the real-world benefits:

• Lower Center of Gravity = less body roll in turns

• Improved Aerodynamics = reduced drag and more stable highway cruising

• Enhanced Traction = rear tires stay planted under acceleration

• More Aggressive Stance = blends perfectly with 2-3” front drops

• Level Ride Profile = eliminates the factory “rake” for a sportier look

• Better Bed Access = loading/unloading becomes easier

Frequently Asked Questions

Q: Do I need to cut or weld anything to install this kit?
A: No, this kit is completely bolt-on. All hardware is included.

Q: Can I still tow after lowering the rear?
A: Yes — light to moderate towing is fine when combined with properly valved DJM 2100 Rear Shocks. For heavy towing, consider load-assist air helper bags.

Q: Will I need a pinion shim or driveshaft spacer?
A: No. The included pinion-adjustable axle brackets allow you to dial in the correct angle without shims or spacers.

Q: Will this work with aftermarket leaf springs?
A: It is designed for OEM leaf springs. For aftermarket leaf packs, please contact us with your spring specifications for compatibility.
