DJM 5"/7" Complete Lowering Kit for 1999–2006 Chevy Silverado & GMC Sierra 1500 

Looking to drop your Chevy Silverado or GMC Sierra 1500 deep into the weeds with a clean, aggressive stance and uncompromised drivability? DJM’s 5-inch front / 7-inch rear complete lowering kit is the ultimate static drop setup for the 1999–2006 model years, including the 2007 Classic. Designed to give your truck a slammed street look without sacrificing handling or safety, this kit includes everything you need—from premium Calmax control arms to a heavy-duty flip kit with frame reinforcement and adjustable pinion brackets.

Whether you're chasing show-quality stance, improved center of gravity, or just want to ride low and turn heads, this DJM drop kit delivers maximum drop with factory alignment capability and suspension travel preserved.

* What Makes the DJM 5"/7" Drop Kit Unique?

This isn't just a generic lowering kit cobbled together with springs and spindles—it's a purpose-built suspension system developed by the experts at DJM Suspension. The key difference? Calmax upper and lower control arms allow you to achieve a full 5-inch front drop while retaining factory coil springs, OEM alignment specs, and proper ball joint geometry.

With other setups, you'd need to compromise comfort, risk binding ball joints, or give up your factory ride quality. Not with DJM.

* What’s Included in the Complete 5"/7" DJM Lowering Kit?

This all-inclusive suspension kit is engineered for:

• 1999–2006 Chevy Silverado 1500 (2WD)

• 1999–2006 GMC Sierra 1500 (2WD)

Kit Contents:

Front Suspension – 5-Inch Drop

• Calmax Upper and Lower Control Arms
  These control arms deliver 5 inches of front drop without changing your stock coil springs. Their geometry is optimized to correct ball joint angles, minimize binding, and allow for accurate alignment—even at this extreme drop.

Rear Suspension – 7-Inch Drop

• Rear Flip Kit with C-Notch and Adjustable Brackets
  The axle is relocated above the leaf springs using DJM’s high-quality flip kit, dropping the rear by 6 inches. A set of extended rear shackles adds another inch to complete the 7" drop.
  DJM’s flip kit also includes:

  • Frame reinforcement plates for C-notch

  • Pinion adjustable axle brackets – unique to DJM kits!

• Rear DJM Shocks

  • Driver’s Side Shock – PN: 1800

  • Passenger’s Side Shock – PN: 1900
    These rear drop shocks are specifically valved for the lowered geometry, improving rebound control and ride quality.

* Why Lower Your Silverado or Sierra with a 5”/7” Drop?

Lowering your truck isn't just about style—though that slammed stance looks amazing—it’s also about performance and road feel. Here's what you get:

• Aggressive Street Stance: Flush wheel arches and minimized wheel gap for that show-ready appearance.

• Better Handling: Lower center of gravity = reduced body roll and more stable cornering.

• Factory Geometry Retained: DJM’s unique control arm design allows you to keep factory spec alignment and stock spring rate.

• Ride Quality Preserved: Unlike spring-only drops, this setup uses geometry correction to maintain suspension travel.

* Installation Overview

Skill Level: Moderate to Advanced
Estimated Time: 8–10 hours
Tools Required:

• Floor jack & jack stands

• Socket and wrench set

• Torque wrench

• Drill (for C-notch install)
