6-Inch Front Lowering Control Arm – Passenger Side Only

Extreme 6" Front Drop • Heavy-Duty Torsion-Bar Compatible • Full Alignment Capability • Precision DJM Calmax Engineering

---

Lowering a GM heavy-duty truck is not like lowering a half-ton pickup. Your 2001–2010 C1500HD, C2500HD, and C3500HD (2WD) is built on one of the strongest frames GM ever made, using an 8-lug torsion-bar front suspension engineered to haul, tow, and work. But when your mission isn’t hauling gravel—but achieving clean stance, show-ready appearance, or modern street performance—you need a suspension system that lowers the truck the right way.

That’s exactly what these DJM Calmax 6-Inch Lowering Control Arms are designed to do.

This listing is for the:

Passenger Side Only — CA2699L-6P

To complete the system, you also need:

• Driver Side Lowering Control Arm – CA2699L-6D

• Upper Control Arms – CA2699U

• Front Shocks – DJM 1415

DJM’s 6-inch lowering arms are the only engineered method to achieve a true 6-inch front drop on a torsion-bar HD truck while maintaining factory alignment and safe suspension geometry. These arms transform your tall, work-ready HD truck into a slammed, aggressive, road-dominating machine—without sacrificing drivability or ruining suspension components.

If you want the deepest static drop possible without cutting frames or going full air ride, these DJM arms are the gold standard.

FITMENT — BUILT FOR GM’S HEAVY-DUTY TORSION-BAR TRUCKS

These 6" lowering arms fit:

(2WD torsion-bar only)

2001–2010 Chevrolet C1500HD (2WD)

2001–2010 Chevrolet C2500HD (2WD)

2001–2010 Chevrolet C3500HD (2WD)

Not compatible with:

• 4WD models

• Coil-spring front ends

• 2011+ HD platform

• Trucks not using DJM upper arms (#CA2699U)

These arms are intentionally engineered only for HD 2WD torsion-bar builds needing a correct, safe, and functional 6-inch front drop.

WHY A 6-INCH DROP REQUIRES ENGINEERED CONTROL ARMS

Most lowering kits don’t stand a chance on HD torsion-bar suspensions.

Owners often try:

• Torsion keys

• De-cranking torsion bars

• “Drop keys”

• Cheap leveling kits reversed

• Cranking adjusters down to the stops

But these create catastrophic suspension issues:

• Harsh, bone-shaking ride
• Bottomed-out front end
• No shock travel
• Excessive ball-joint angle
• Constant alignment problems
• Tire wear that destroys rubber in weeks
• Dangerous bump-steer
• Premature suspension failure

GM did not design HD torsion-bar geometry to operate at such extreme angles.

DJM did.

• A true 6-inch drop
• Correct geometry
• Proper camber/caster range
• Preserved ride quality
• Safe ball-joint articulation
• Smooth steering
• Predictable handling
• Deep drop without destroying components

These control arms reposition pivot points to achieve the full 6" drop naturally, without forcing other components into unsafe angles.

WHAT THESE 6-INCH LOWER CONTROL ARMS PROVIDE

1. True 6-Inch Static Front Drop

Not by key-cranking—but through engineered suspension geometry.

2. Corrected Ball-Joint Positions

Ensures proper articulation and prevents wear.

3. Maintains Torsion Bar Functionality

The truck drives like a lowered HD should—smooth, stable, and strong.

4. Factory Alignment Capability

Once paired with DJM Upper Control Arms, alignment returns to full OEM range.

5. Heavy-Duty DJM Calmax Construction

These aren’t passenger truck arms—they’re built to withstand 8-lug HD loads.

6. Urethane Bushings Installed

Provides improved steering feel and longer lifespan.

7. New Ball Joints Included

No rebuilding, pressing, or modifying needed.

8. Perfect Foundation for Show, Street, or Stance Builds

A 6-inch front drop completely transforms the HD appearance.

If you want to tuck wheels, achieve aggressive rake, or build a static-dropped HD, this is where it starts.

WHY YOU MUST USE DJM UPPER CONTROL ARMS (#CA2699U)

The upper arms are not optional.
With a deep 6-inch drop, the upper control arms must be replaced for:

• Correct caster & camber

• Safe ball-joint angles

• Proper suspension travel

• Reduced bump-steer

• Full alignment adjustability

Stock upper arms cannot accommodate the geometry changes created by a 6-inch drop.

Without upgraded uppers:

• The truck cannot be aligned
• Ball joints will bind
• Ride quality will suffer
• Safety is compromised

Pairing lower + upper arms creates a complete engineered system.

---

SHOCKS REQUIRED — DJM 1415

With a 6-inch drop, factory shocks will bottom out instantly.

Using DJM 1415 shocks ensures:

• Correct travel length

• Proper damping

• Improved ride quality

• Safe suspension motion

• No topping or bottoming out

Each shock is sold individually.

WHAT A 6-INCH DROP LOOKS & FEELS LIKE

A truck lowered with these arms experiences:

✔ Dramatically improved appearance

✔ Better wheel stance

✔ Lower center of gravity

✔ Improved cornering behavior

✔ Sharper turn-in feel

✔ Less body roll

✔ More aggressive front rake

✔ Better road feedback

Static-dropping your HD creates a look that air ride can't perfectly replicate:

• Clean

• Solid

• Static strong

• Street-ready

• Show-ready

If you're aiming for the signature HD 6/8 drop or a slammed HD street cruiser, these arms are essential.
