Complete 3-Inch Front / 4-Inch Rear Lowering Kit with Shocks
If you’re ready to dramatically upgrade the stance, handling, and overall road presence of your truck, this complete 3-inch front / 4-inch rear lowering kit with shocks delivers everything you need for a smooth, predictable drop with true DJM quality. Designed for owners who demand a performance-oriented ride without sacrificing durability, this kit combines 3-inch DJM lowering control arms, a 4-inch rear hanger & shackle drop system, and a passenger-side rear shock extender—plus all recommended shocks included.
No guesswork. No piecing together parts. No compatibility concerns.
Just a clean, balanced drop engineered for real-world performance.
DJM has been building industry-leading lowering components for decades, and this kit follows the same core principles: OEM-level fitment, unmatched reliability, and ride quality that performs on the street, freeway, and daily commute. Whether you're chasing tighter handling, a leveled stance, or a full custom truck appearance, this setup gives you the right combination of ride comfort and precision geometry correction.
Why This 3/4 Lowering Kit Is the Perfect Choice
Lowering a truck the right way means more than simply reducing ride height. Geometry, alignment adjustability, shock performance, and suspension travel all need to work together. This kit was designed as a complete solution—not just a pile of parts—to deliver factory-like drivability with the aggressive stance today’s custom truck enthusiasts demand.
With 3-inch lowering control arms, you maximize suspension travel and maintain correct ball joint angles, eliminating the harsh ride associated with cut springs or stacked components. The 4-inch rear drop uses a hanger/shackle relocation design, which preserves your leaf spring geometry, keeps load-handling characteristics intact, and prevents bottom-outs—something cheaper flip kits struggle with.
Pair that with the included shocks— Front 1415, Rear Driver 1900, and Rear Passenger 2000—and you get a suspension system that feels settled, controlled, and confidence-inspiring in all daily driving situations.
FRONT DROP: 3-Inch DJM Lowering Control Arms
Lowering the front of your truck by 3 inches requires much more precision than simply trimming coils or using inferior components. DJM’s legendary 3-inch lowering control arms are built specifically to maintain proper suspension geometry while improving ride quality.
Key Benefits of DJM 3" Lowering Control Arms:
✔ Corrected Ball Joint Angles
No binding. No premature wear. Your suspension moves through the full travel range smoothly and safely.
✔ Maintains OEM Coil Spring Rate
Ride quality stays comfortable—not stiff or bouncy.
✔ Increased Suspension Travel
Unlike drop spindles or cut coils, these arms allow the front end to move naturally without hitting bump stops.
✔ Heavy-Duty Construction
DJM uses thick-gauge steel, reinforced welds, and precise jigs to guarantee alignment, strength, and long-term durability.
✔ Direct Bolt-On Installation
Nothing to cut. Nothing to modify. Everything fits as intended from the factory locations.
The result is a clean 3-inch front drop that looks incredible and functions exactly the way a modern suspension system should.
REAR DROP: 4-Inch Hanger & Shackle Lowering System
Lowering the rear of your truck by 4 inches while keeping ride quality intact can be a challenge—but DJM’s hanger and shackle drop design gets it right. Instead of forcing your leaf springs into unnatural angles or sacrificing towing strength, this kit relocates the spring mounts upward toward the frame, producing a smooth, predictable drop without compromising load-carrying potential.
Why the Hanger/Shackle Design Is Superior:
✔ Maintains Factory Spring Rate & Rear Geometry
Your truck rides like it’s meant to—not harsh or bottomed-out.
✔ No Drastic Pinion Angle Changes
Your driveline stays happy with correct alignment and no vibration.
✔ Keeps Rear Suspension Travel Intact
Unlike flip kits, this method avoids reducing travel to the point of constant bump stop contact.
✔ Heavy-Duty Brackets Built for Strength
DJM’s brackets are thick, rigid, and designed to handle real-world torque and stress.
✔ Consistent 4-Inch Drop
A reliable, measured drop that gives your truck an aggressive but functional stance.
With this rear setup, your truck benefits from a lower center of gravity, sharper handling, and a sleek stance that flows perfectly with the front 3-inch drop.
Passenger-Side Shock Extender Included
Lowering the rear suspension changes shock angle and travel, especially on the passenger side. Instead of forcing your shocks to operate at a poor angle, this kit includes a precision-engineered shock extender designed to restore optimal shock geometry.
Improved Shock Performance Includes:
-
More consistent damping
-
Better rear-end stability
-
Reduced bottoming-out
-
Extended shock lifespan
This extender keeps the included DJM shock operating within its ideal range, improving ride smoothness and overall performance.
This Kit INCLUDES All DJM-Recommended Shocks
To ensure optimal ride quality and proper suspension performance after the drop, DJM includes the correct shock absorbers for each specific location:
Front Shocks: DJM 1415
Engineered for lowered control arm geometry, offering a stable and responsive front-end feel.
Rear Driver Shock: DJM 1900
Tuned for the relocated hanger/shackle drop setup, providing consistent damping under load.
Rear Passenger Shock: DJM 2000
Matched for use with the included shock extender, ensuring balanced rear suspension performance.
This matched shock set eliminates the guesswork and prevents common lowering problems like:
-
Excessive bounce
-
Harsh bottoming-out
-
Unstable rear-end movement
-
Shock overextension
With this kit, you get a complete, optimized suspension solution, not mismatched components.
