6-Inch Front Lowering Control Arm – Driver Side Only

Extreme 6" Drop • Torsion-Bar Suspension Compatible • Full Alignment Capability • Heavy-Duty DJM Calmax Construction

---

Lowering a heavy-duty GM truck is a task that requires more than simple torsion key adjustments or unsafe aftermarket shortcuts. When you’re working with 2001–2010 C1500HD, C2500HD, and C3500HD (2WD) models—GM’s 8-lug, big-frame, big-capacity workhorses—you’re dealing with suspension components engineered to carry immense loads and operate under extreme conditions. But what if you want that same heavy-duty capability and a dramatic, show-stopping slammed stance?

For builders who want a true, geometry-correct, fully functional 6-inch front drop without destroying ride quality, ball joints, tire life, or alignment accuracy, there is only one correct solution:

DJM Calmax 6-Inch Lowering Control Arms — Driver Side Only.

To complete the system, purchase:

• Passenger Side Arm – CA2699L-6P

• Upper Control Arms – CA2699U

This listing is for the Driver Side only.

With these arms, you’re not compromising—you're upgrading to the only engineered lowering method that safely delivers a full six inches of drop on a torsion-bar GM HD platform while maintaining alignment to factory specifications.

This is the deepest front drop possible on these trucks without frame cutting, custom fabrication, or full air-ride systems.

WHY DROP A GM HD TRUCK 6 INCHES IN THE FRONT?

GM designed the HD line to ride high for towing, plow packages, clearance, and load handling. That’s great for work—but not ideal for:

• Custom street trucks

• Show builds

• Wide wheel/tire setups

• Modern stance designs

• Lowered work trucks

• Performance-handling builds

A 6-inch front drop drastically transforms:

• The look

• The feel

• The drivability

• The wheel gap

• The center of gravity

• Overall performance on the street

A lowered HD instantly becomes sleek, aggressive, planted, and far more modern. It’s the foundation of any serious static drop or show-truck stance.

WHY YOU CANNOT LOWER GM HD TRUCKS 6" WITH TORSION KEYS

People often attempt extreme drops on torsion-bar trucks using:

• Drop keys

• De-cranked torsion adjusters

• “Cheater” torsion key flips

• Unsafe suspension hacks

Every one of these methods results in:

• Destroyed ride quality
• Bottoming-out suspension
• Zero travel
• Unfixable alignment problems
• Ruined ball joints
• Dangerous steering geometry
• Premature tire wear
• Unsafe handling

GM torsion-bar HD trucks cannot be safely lowered 6 inches without redesigned suspension geometry.

DJM’s Calmax 6-Inch Lower Control Arms solve all of these issues by:

✔ Repositioning pivot points
✔ Correcting ball-joint angles
✔ Engineering proper travel range
✔ Ensuring full alignment adjustability
✔ Maintaining torsion-bar preload
✔ Providing safe steering and suspension movement

FEATURES OF DJM 6-INCH LOWER CONTROL ARMS

These control arms are engineered specifically for the massive weight and strength demands of Chevy’s HD platforms.

Not by cranking torsion bars, but by repositioning the suspension architecture.

2. Corrected Ball-Joint Angles

Prevents binding, premature wear, and dangerous joint stress.

3. Heavy-Duty DJM Calmax Construction

Built from thick-gauge steel to handle the weight of 8-lug GM HD trucks.

4. Urethane Bushings Installed

Increases control, reduces deflection, and improves longevity.

5. "Twin Tube" Pivot Sleeves

Ensures smooth arm articulation even under load.

6. New HD Ball Joints Included

No need to buy or press in new joints—ready for installation.

7. Retains OEM Torsion Bar Functionality

The ride remains smooth, controlled, and stable.

8. Maintains Full Alignment Capability

Caster, camber, and toe can be set to OEM specifications with the required upper arms.

THE REQUIRED COMPONENTS — THIS IS IMPORTANT

To run these 6-inch arms correctly and safely, you MUST also use:

1. DJM Upper Control Arms – #CA2699U

These solve the alignment and geometry challenges created by a deep drop.
Stock uppers WILL NOT work.

2. Passenger Side 6-Inch Arm – #CA2699L-6P

This listing is the driver side only.
You need the passenger arm for a complete left/right system.

3. DJM Front Shocks – #1415

Lower ride height requires corrected shock length and valving.

Having all three ensures:

• Proper ride quality

• Safe ball-joint movement

• Full suspension travel

• Correct steering behavior

• Accurate tire wear

• Professional-grade handling

DJM even sells a complete kit:

DJM2699-6/8

For convenience and cost-efficient purchasing.
