2007-2018 Chevy/GMC Silverado/Sierra 1500 – 5 Inch Rear Lowering Kit
Precision-Engineered Axle Flip System with Adjustable Pinion Angle for a Clean and Aggressive 5” Drop

If you’re looking to dramatically improve the stance and street performance of your 2007-2018 Chevy Silverado 1500 or GMC Sierra 1500, the DJM 5 Inch Rear Lowering Kit is the ultimate solution. This complete axle flip kit moves the axle from underneath the leaf spring and repositions it above, creating a reliable and consistent 5-inch drop that levels the truck and gives it a true performance stance. By incorporating an inverted shackle hanger and a longer shackle setup, DJM created a kit that doesn’t just look good—it performs.

Because GM welded the forward spring hanger to the frame, traditional hanger swaps are not possible on these models. Instead of cutting or fabricating your frame (which can affect structural integrity), DJM engineered a bolt-on axle flip system that uses adjustable axle brackets to correct your pinion angle for smooth and vibration-free driving.

 Why This 5” Rear Drop Kit Is the Preferred Choice

Unlike cheap flip kits that ignore geometry, this DJM Rear Lowering Kit protects suspension travel and driveline angles with proper bracket positioning and premium hardware. Every component in this kit was specifically designed for the GMT900 platform, which includes both the Chevy and GMC 1500 trucks (2WD models) from 2007 through 2018.

Here’s what makes it the industry’s top-rated solution:

✔ Factory Ride, Aggressive Stance

The axle flip does not alter your leaf spring rate, so you maintain a smooth factory-like ride, even with the more aggressive stance.

✔ Adjustable Pinion Brackets for Driveline Precision

Once the axle is moved above the spring, your factory pinion angle is no longer correct. DJM includes adjustable axle brackets that let you dial the pinion back into alignment—eliminating the vibration and premature U-joint wear that cheaper kits often cause.

✔ Built-In Flexibility (4” or 5” Drop)

Although this version is designed to net a 5" rear drop, the shackle assembly includes two mounting holes, which allow you to set up a 4-inch drop if desired. This is ideal for customers who may raise the truck back up in the future or match a different front drop.

✔ No Cutting, No Welding

Everything in this kit bolts onto the factory frame using existing holes or premium mounting hardware, meaning the structural integrity of your frame is never compromised.

 What’s Included in the DJM 5” Rear Lowering Kit?

Shocks NOT Included.
For optimal ride quality and safe suspension travel, DJM recommends using Rear Shock 2100 (sold individually)

Key Benefits of the 5-Inch Rear Drop on Silverado/Sierra 1500

• Improved Handling – Lower center of gravity reduces body roll during cornering.

• Enhanced Appearance – Eliminates the factory rake for a flat, level, performance-inspired profile.

• Better Bed Accessibility – Easier to load/unload cargo.

• Factory Load Capacity Maintained – Leaf spring is untouched, so towing performance remains stable (when paired with proper shocks).

• Correct Driveline Alignment – Adjustable bracket ensures vibration-free, long-term use.

• Bolt-On Install – No cutting or welding of the frame or suspension mounting points.

Installation Tips from the Pros

Taking the time to properly align and tighten everything ensures the best results. Below are some recommendations from professional installers and DJM:

• Use High-Quality Jack Stands
Always support the truck on the frame rails and keep the rear axle free to drop as needed.

• Mock Up Before Final Torque
Install all brackets finger-tight first, cycle the suspension, and verify clearance at full travel before final torque.

• Set Pinion Angle with Truck on the Ground
After installation, lower the truck to the ground and use an angle finder to align the pinion via the adjustable axle brackets.

• Don’t Forget the Shocks
Factory shocks are too long for a 5-inch drop and will bottom out. Pair this kit with DJM 2100 Rear Shocks for the best damping and travel.

Recommended Add-Ons  

 Real-World Benefits: Why Lowering Is More Than Looks

A properly lowered truck not only looks better—it performs better. Whether you use your Silverado or Sierra as a daily driver, weekend cruiser, or light hauler, a 5” rear drop offers meaningful advantages:

Better Aerodynamics

Lowering the rear end smooths airflow under the chassis, reducing turbulence and drag at highway speeds.

Increased Traction and Stability

Lowering shifts the vehicle’s center of gravity lower to the ground. That means less body roll and improved rear-tire traction during hard acceleration.

Maintained Payload Stability

Unlike lowering blocks or spring-cutting methods, this rear flip kit keeps the original spring rate intact, allowing you to retain load capacity.

Precision Appearance

A level, 4/5 or 3/5 drop is considered by many builders to be the “ideal stance” for these trucks. It looks aggressive while still usable every day.

Frequently Asked Questions

Q: Can I still tow with this kit installed?
A: Yes. Light and moderate towing is totally acceptable as long as you use properly valved DJM 2100 shocks. For heavy towing, consider adding helper bags.

Q: Does this kit require any cutting or drilling?
A: No. The system is 100% bolt-on and designed to work with factory frame mounting points. Drilling is not required.

Q: What if I want a 4” drop instead of 5”?
A: This kit supports both. It comes with two shackle mounting positions that allow either a 4-inch or 5-inch drop depending on which hole you use.

Q: Will I need a driveshaft spacer?
A: No driveshaft spacer is required. The included adjustable pinion brackets handle all driveline correction.
