3-Inch Front Lowering Control Arm – Passenger Side Only

Precision 3" Front Drop • Torsion-Bar Suspension Compatible • Alignment-Correct Design • Heavy-Duty Ball Joints & Urethane Bushings Installed

---

Heavy-duty GM trucks are built strong, built to last, and built to work. But they also sit tall—very tall—especially in the front. The 2001–2010 C1500HD, C2500HD, and C3500HD 2WD trucks are known for their rugged stance, but for builders who want a cleaner, more aggressive appearance with improved handling and a sport-truck style ride, the factory height simply doesn’t cut it.

For those who want a true, geometry-correct 3-inch front drop on GM’s torsion-bar suspension—without compromising ride quality, ball joint angles, or alignment—the best solution is a set of DJM 3-Inch Front Lowering Control Arms.

This listing is for the:

Passenger Side Only

To complete the kit, you’ll need the matching Driver Side Control Arm – CA2602L-3D.

These control arms are engineered specifically for GM’s torsion-bar HD platforms, offering the smoothest, safest, and most reliable 3-inch front drop available.

WHY LOWER GM TORSION-BAR HD TRUCKS WITH CONTROL ARMS?

Unlike half-ton trucks that use coil springs, your 2001–2010 C1500HD/C2500HD/C3500HD uses a torsion-bar suspension. While some shops try to lower these trucks by simply adjusting (or “re-indexing”) torsion keys, that approach causes major issues:

• Harsh, bouncy ride

• Reduced travel

• Poor alignment

• Premature ball joint wear

• Bottoming out

• Unsafe geometry

Lowering keys may drop the height, but they destroy ride quality and component life.

DJM’s lowering control arms correct all the geometry problems and allow you to achieve a true 3-inch front drop while maintaining:

• Proper ball-joint angles

• Proper caster and camber range

• Full suspension travel

• Factory torsion-bar preload

• Safe steering geometry

• Smooth, controlled ride feel

In other words, these arms lower your truck the right way.

WHAT THESE CONTROL ARMS DO

These DJM lower control arms drop the front suspension a true 3 inches by repositioning key pivot points while maintaining proper angles for:

• Ball joints

• Steering knuckles

• Shock absorbers

• Control arm travel

• Torsion bar load

You get:

✔ A genuine 3-inch drop
✔ Full suspension travel
✔ OEM-like ride characteristics
✔ Corrected geometry
✔ Safety and performance engineered into the arm

This is the same drop height people try (and fail) to achieve with torsion keys—but with none of the issues.

WHAT A 3-INCH FRONT DROP DOES FOR YOUR HD TRUCK

Lowering the front end of your C1500HD/C2500HD/C3500HD dramatically changes both appearance and driving feel.

1. Gets Rid of Excessive Factory Rake

These trucks sit nose-high by design. A 3” drop levels the stance or sets up a perfect leveled look with a rear drop.

2. Enhances Wheel Fitment

A lowered front end pairs perfectly with:

• 17”

• 20”

• 22”

• Even 24” custom wheels

Wheel gap is dramatically reduced, improving aesthetics.

3. Better Handling and Stability

Lower center of gravity =
✔ Less body roll
✔ More confident cornering
✔ Stronger road feel
✔ Improved braking response

4. Cleaner Custom Look

The truck immediately looks:

• More aggressive

• More modern

• More proportional

• Show-ready

5. Maintains OEM Comfort

Because geometry isn’t distorted like it is with torsion keys.

If you want a lowered look without ruining the HD ride quality, these control arms are the ideal solution.

INSTALLATION DETAILS

Difficulty: Moderate

Time Required: 3–5 hours

Recommended Tools:

• Jack & stands

• Ball joint separator

• Metric socket set

• Torque wrench

• Torsion bar unloading tool

• Impact gun (optional but helpful)

Steps (General Overview):

1. Relieve torsion-bar pressure using proper unloading tool

2. Remove factory lower control arm

3. Install new DJM 3-inch drop control arm

4. Reinstall torsion bar

5. Install recommended shock (see below)

6. Torque to manufacturer specifications

7. Complete professional alignment

After installation, always perform a full front-end alignment.

SHOCKS ARE REQUIRED (NOT INCLUDED)

To maintain correct damping and travel, DJM requires the use of:

Front Shock #1415

Using factory shocks will result in:

• Harsh rebound

• Bottoming out

• Bouncing over bumps

• Poor handling stability

Always pair the control arms with the recommended shocks for the best ride performance and longevity.

PERFECT FOR EVERY TYPE OF GM HD BUILD

These control arms are ideal for:

✔ Daily drivers

✔ HD towing rigs (front drop does not reduce towing capability)

✔ Street performance trucks

✔ Lowered work trucks

✔ Show trucks

✔ Custom wheel/tire fitments

✔ OBS/NBS inspiration builds

Whether you're building a functional lowered HD truck or a full show-quality custom, these arms are the correct foundation.
