1999–2006 Silverado/Sierra 1500 4WD (Torsion Bar Front End) 3" Front / 5" Rear Complete Lowering Kit with Shocks

Give Your Silverado or Sierra a Bold Stance with Superior Ride Quality

If you own a 1999–2006 Chevy Silverado 1500 4WD or GMC Sierra 1500 4WD equipped with a torsion bar front end, you know the combination of rugged reliability and performance these trucks offer. But while GM nailed durability, many truck enthusiasts prefer a sleeker, lowered stance that adds style without sacrificing capability.

This 3-inch front / 5-inch rear complete lowering kit with shocks is engineered specifically for your 4WD Silverado or Sierra. Using precision lowering control arms designed to work seamlessly with factory torsion bars, and a rear axle flip kit with lifting shackles, this kit delivers a controlled drop with factory alignment specs and smooth ride quality.

What’s Included in the Complete 3/5 Drop Kit?

This isn’t just a collection of parts—it’s a comprehensive lowering system with every component you need to achieve a perfect stance:

Front Suspension – 3" Drop with Control Arms

• Lowering Control Arms engineered to work with factory torsion bars.

• Provides a true 3-inch drop while maintaining proper geometry and alignment range.

• Retains the ride quality and durability of your 4WD setup.

Rear Suspension – 5" Drop with Axle Flip & Shackles

• Axle Flip Kit relocates the axle from beneath the leaf springs to above, dramatically lowering the rear.

• Lifting Shackles raise the rear slightly to achieve a final 5-inch drop instead of a more extreme 7-inch flip.

• Includes pinion angle brackets for proper drivetrain alignment.

• Heavy-duty U-bolts, spring plates, and installation hardware included.

Shocks – Tuned for Lowered Applications

Factory shocks aren’t designed for lowered ride height. That’s why this kit includes performance shocks designed to maintain comfort and handling at reduced suspension travel:

• Front Shock #1415

• Rear Driver’s Shock #1900

• Rear Passenger’s Shock #2000

With these shocks, you’ll enjoy a balanced combination of comfort, stability, and control.
