DJM Suspension 4″ Front / 6″ Rear Complete Lowering Kit for 1999–2006 Chevy & GMC 1500 (2WD)

The Classic 4/6 Drop—Timeless, Proven, Legendary

If you ask truck diehards for the most iconic drop, they’ll say the 4/6—famously pioneered by the ‘88–’98 C1500. It’s not just a drop; it’s a benchmark. Now DJM brings you that legacy with a kit that uses control arms up front (no spindles), retains factory springs, and lowers the rear 6 inches using a frame-supported flip kit. You get a head-turning stance with a smooth ride—no bouncing, no rubbing, just flawless form and function.

* What’s Inside the Kit & How It Works

Front Suspension – 4″ Drop Using Control Arms

DJM Lower Control Arms (Front) – Engineered to give you a factory-feel 4″ drop while maintaining proper ball-joint geometry and full suspension travel. These are far superior to spindles or drop coils.
Internal Link: Check out the front lowering control arms.

Rear Suspension – 6″ Drop via Flip Kit

DJM Axle Flip Kit with C-Notch Reinforcement – Designed to drop your rear 6 inches with robust frame support. It includes pinion-adjustable brackets for driveline alignment.
Internal Link: View the rear flip kit.
Extended Leaf Spring Shackles – Complete the drop and refine leaf spring geometry for ride quality.

Shock Absorbers Included

Front Shock – Model 1415
Rear Driver Shock – Model 1800
Rear Passenger Shock – Model 1900 (includes shock extender hardware in the flip kit)

* Why the 4/6 Drop is Still the Gold Standard

Significant Stance Change — Unmistakable visual impact without being too low to live with.
Factory-Ride Feel — Geometry stays correct; ride remains smooth.
DIY-Friendly, Performance-Driven — Ideal for show trucks or everyday cruisers.
