1973–1987 Chevy C-10 – 2 Inch Lowering Shackles

Classic Drop • Perfect Stance Correction • Simple Bolt-On Upgrade • The Original Sport Truck Mod

---

Lowering a classic 1973–1987 Chevy C-10 (“Squarebody”) is one of the most satisfying upgrades you can make, both visually and performance-wise. These trucks are icons—known for their timeless lines, rock-solid frames, and unmatched presence on the road or at a show. But from the factory, they also came with one unmistakable trait:

The “Stink Bug” Rear-End Stance.

High in the back.
Low in the front.
Unbalanced and awkward.

For decades, C-10 owners have corrected this look with one of the simplest and most effective suspension mods ever created: the 2-Inch Lowering Shackle.

This set of DJM 2” Rear Lowering Shackles is designed specifically for the 1973–1987 Chevy C-10 truck platform and remains one of the most popular and most trusted ways to achieve the perfect rear drop without affecting ride quality, load capability, or suspension geometry.

Whether you're building a daily-driven Squarebody, a restomod cruiser, a bagged show truck foundation, or a performance street machine, these shackles provide the cleanest, easiest, and safest way to get the back of your truck down where it belongs.

WHY LOWERING SHACKLES ARE STILL THE #1 MOD FOR C-10 REAR DROPS

Shackles have been around since the earliest days of sport truck culture because they check ALL the boxes:

• Affordable
• Easy installation
• Predictable drop height
• Loaded with benefits
• Maintain factory ride quality
• No negative side effects

For a classic C-10, shackles remain the best method for minor-to-moderate rear drops, especially when your goal is:

• Reducing the factory rake

• Leveling the truck with a front drop

• Preparing the truck for bags later

• Improving stance with minimal effort

• Enhancing the look without harming drivability

DJM Shackles deliver a true, consistent, 2-inch drop.

WHAT A 2-INCH DROP DOES FOR A SQUAREBODY

1. Levels out the stance

The factory “nose-down” posture disappears instantly.

2. Improves aesthetics dramatically

Your C-10 suddenly looks:

• Lower

• Longer

• Meaner

• More aggressive

• Balanced

3. Enhances handling

Lower center of gravity = improved cornering stability.

4. Better wheel and tire appearance

Especially beneficial with:

• 20” wheels

• 22” wheels

• Deep-dish setups

• Classic rally wheels

• Custom offsets

5. Ideal for mild drops or combining with front lowering options

Pair with:

• 2-inch lowering coils

• 2.5-inch drop spindles

• 3-inch front arms

• Full 4/6 static drop kits

A 2” rear shackle drop integrates perfectly into any overall lowering plan.
