Designed Specifically for 2001–2010 Chevy Silverado 1500HD 2WD Trucks

This lowering system is engineered exclusively for:

• 2001–2010 Chevy Silverado 1500HD

• 2WD models only

The 1500HD platform uses a unique heavy-duty front suspension and rear leaf spring configuration that requires specialized components for proper lowering. This kit is designed to work with the factory torsion bar front suspension and heavy-duty rear leaf springs while maintaining proper geometry, steering alignment, and suspension durability.

This is not a universal lowering kit or a generic solution — it is purpose-built for the 1500HD chassis.

A Balanced Drop – 3 Inches Front, 5 Inches Rear

This kit provides a carefully engineered drop that levels the truck perfectly for an aggressive yet practical stance:

• 3-inch front drop using Calmax lowering control arms

• 5-inch rear drop using a hanger and shackle relocation system

This combination delivers:

• A level, sporty stance

• Reduced wheel gap front and rear

• Improved center of gravity

• Enhanced handling characteristics

• Excellent street drivability

Unlike extreme drop kits that compromise suspension travel and ride quality, this setup keeps your HD truck low enough to look great while still functioning like a proper daily driver.

Front Suspension – Calmax Lowering Control Arms for Factory Ride Quality

The front of this kit uses premium Calmax lowering control arms — one of the most proven and respected lowering methods for torsion bar GM trucks.

Instead of cranking torsion bars or using drop spindles, Calmax control arms lower the truck by repositioning the suspension geometry itself.

Key benefits of Calmax lowering control arms:

• Retain factory torsion bar spring rate

• Preserve near-factory ride quality

• Correct ball joint angles

• Maintain proper steering and alignment geometry

• Reduce stress on factory suspension components

• Improve handling and steering response

The control arms are a direct bolt-on replacement for your factory upper control arms. Simply remove the stock arms and install the Calmax units — no torsion bar cranking, no harsh ride, and no compromised suspension travel.

Premium Construction – Urethane Bushings & Heavy-Duty Ball Joints

Each set of Calmax control arms features:

• High-performance urethane bushings for improved response and durability

• All-steel heavy-duty ball joints engineered for lowered ride height

• Reinforced control arm design for heavy-duty truck use

The urethane bushings reduce deflection and improve steering precision while maintaining excellent ride comfort. The upgraded ball joints are designed specifically to operate at lowered angles, preventing binding, premature wear, and alignment issues that often occur when lowering heavy trucks improperly.

This ensures:

• Long service life

• Quiet operation

• Proper alignment range

• Safe suspension articulation

---

Front Shocks – Matched for Lowered Suspension

To complement the lowered front suspension and maintain proper damping control, DJM recommends:

• Front Shock #1415 (Qty 2)

These shocks are valved specifically for lowered torsion bar suspensions and provide:

• Improved ride control

• Reduced body roll

• Better bump absorption

• Proper travel length for lowered ride height

Using the correct shocks is critical to maintaining ride comfort and protecting suspension components on lowered HD trucks.

---

Rear Suspension – 5 Inch Hanger & Shackle Lowering System

The rear of the truck is lowered using a proven 5-inch hanger and shackle relocation system.

Instead of using lowering blocks — which can create axle wrap, traction issues, and stress on leaf springs — this system repositions the leaf spring mounting points higher on the frame to achieve a true 5-inch drop safely and correctly.

Rear drop achieved by:

• Relocating the front leaf spring eye hanger upward

• Installing matching lowered shackles

• Maintaining proper leaf spring geometry

This method delivers:

• Stronger axle control

• Improved traction

• Reduced axle wrap

• Better ride quality

• Long-term suspension durability

---

IMPORTANT Fitment Note – Inspect Your Factory Leaf Spring Hangers Before Ordering

Due to production variations across the 1500HD platform, it is extremely important to inspect your factory leaf spring front eye hangers before ordering.

While nearly all 1500HD trucks use the correct hanger style, GM did produce minor variations.

Before ordering, take a moment to:

• Visually inspect your factory front leaf spring eye hangers

• Compare them to the reference photo provided with the kit

This quick inspection can save you time, frustration, and installation delays by ensuring you receive the correct components for your specific truck.

---

Rear Shocks – Proper Damping for Lowered HD Trucks

Lowering the rear suspension requires shocks with the correct extended and compressed lengths to maintain proper travel and ride control.

DJM recommends:

• Rear Driver Side Shock: DJM 2200 (Qty 1)

• Rear Passenger Side Shock: DJM 2400 (Qty 1)

These shocks are valved specifically for the 5-inch rear drop and provide:

• Improved ride comfort

• Better axle control

• Reduced bottoming

• Extended shock lifespan

Using the proper shocks ensures your lowered rear suspension performs safely and smoothly.
