3 Inch Front / 5 Inch Rear Complete Lowering Kit

Designed for Crew Cab trucks with leaf spring eye hangers welded to the frame

If you are looking to give your 2003–2006 Chevy Silverado or GMC Sierra 1500 Crew Cab a clean, aggressive stance without sacrificing ride quality, drivability, or alignment, this 3/5 Complete Lowering Kit is engineered specifically for your truck. Designed for 2WD Crew Cab models with factory leaf spring eye hangers welded to the frame, this system delivers a true 3-inch drop in the front and a 5-inch drop in the rear, creating a balanced, performance-inspired profile that looks right from every angle.

This is not a “cut springs and hope for the best” setup. Every component in this kit is purpose-built to work together, maintaining proper suspension geometry, improving handling, and ensuring long-term reliability. Whether you are building a street truck, daily driver, show truck, or audio demo vehicle, this lowering kit provides the foundation you need for both looks and performance.

Engineered Specifically for 2003–2006 (2007 Classic) Crew Cab Trucks

Lowering a Crew Cab Silverado or Sierra presents unique challenges, especially on trucks where the rear leaf spring eye hangers are welded to the frame from the factory. Many generic kits overlook this detail, leading to poor fitment, alignment issues, or unsafe suspension geometry.

This kit is designed specifically for those welded-hanger Crew Cab trucks, eliminating guesswork and ensuring correct installation. Every bracket, shackle, and control arm is engineered to bolt into place while preserving proper suspension travel and driveline angles.

3-Inch Front Drop Using Lowered Control Arms (Factory Coil Springs Retained)

The front suspension is lowered using precision-engineered lowered control arms, allowing you to achieve a full 3-inch drop while retaining your factory coil springs. This approach delivers multiple advantages over traditional spring cutting or lowering springs:

• Maintains factory spring rate for ride comfort

• Preserves suspension travel

• Keeps alignment within correct adjustment range

• Improves steering response and stability

Each control arm comes fully assembled with:

• New heavy-duty ball joints

• High-quality urethane bushings

• Durable “twin tube” pivot sleeves

This pre-assembled design simplifies installation, reduces shop time, and ensures every critical wear component is brand new when your truck hits the road.

5-Inch Rear Drop with Axle Flip + Corrected Shackle Geometry

Lowering the rear of a Crew Cab truck properly requires more than just flipping the axle. This kit uses a complete rear axle flip system combined with new shackle hangers and extended shackles to achieve a true 5-inch rear drop while maintaining correct suspension geometry.

How the Rear System Works

1. Axle Flip Kit
   Moves the rear axle from under the leaf springs to on top, providing the bulk of the drop.

2. New Rear Shackle Hangers & Longer Shackles
   After the axle flip, the new hangers and extended shackles raise the rear suspension mounting points back up, dialing the drop in precisely to 5 inches while improving ride quality and suspension travel.

3. Pinion Adjusting Axle Brackets
   Correct driveline angles to prevent vibration, premature U-joint wear, and driveline stress.

4. Heavy-Duty Hardware Included
   New U-bolts, spring plates, and all necessary mounting hardware are included for a complete, bolt-on installation.

This system not only lowers the truck correctly but also ensures it drives straight, rides smooth, and stays reliable mile after mile.

Matched Shock Package for Proper Damping

Lowering a truck without addressing shock length is one of the most common mistakes. This kit includes application-specific shocks designed to work with the new ride height, ensuring proper damping, control, and ride comfort.

Shock Configuration Included

• Front Shocks: 1415 (Qty 2)

• Rear Driver Side Shock: 1900

• Rear Passenger Side Shock: 2000

The staggered rear shock lengths account for the factory shock mounting geometry, ensuring correct travel and consistent damping on both sides of the truck.

Ride Quality You Can Feel

One of the biggest concerns when lowering a truck is ride quality. Thanks to the retained factory coil springs, corrected suspension geometry, and matched shock valving, this kit delivers a controlled, comfortable ride that works equally well on daily commutes, highway cruising, and long road trips.

Benefits include:

• Reduced body roll

• Improved steering response

• Predictable handling

• No harsh bottoming or excessive bounce

This is a lowering kit you can drive every day, not just park at shows.

Built for Strength, Longevity, and Real-World Use

Every component in this kit is manufactured using high-strength materials, precision welding, and proven designs trusted by enthusiasts and builders nationwide. The control arms, brackets, and hardware are built to withstand real-world driving conditions, from potholes and highway miles to loaded beds and weekend cruising.

Urethane bushings provide improved durability over rubber while still allowing controlled suspension movement, reducing deflection and improving handling without introducing excessive noise or vibration.
