2019–2026 Chevy Silverado / GMC Sierra 1500 Lowering Shackles | 1", 1.5" or 2" Rear Drop
Lower the Rear. Dial In Your Truck’s Stance.
Give your truck a cleaner, more balanced profile without lifting the front. The Apoc Industries rear lowering shackle kit for the 2019–2026 Chevy Silverado 1500 and GMC Sierra 1500 reduces rear ride height to help bring down that tail-high factory stance. Choose a 1", 1.5" or 2" rear drop to match the look you want.
IMPORTANT: This kit will NOT fit a mono-composite leaf spring. Check your truck’s rear leaf-spring configuration before ordering.
Built for a Cleaner Reverse-Level Look
- Your choice of rear drop: Select 1", 1.5" or 2" using the Drop Size option. Each kit includes the selected size.
- Leave the front suspension alone: Lower the rear to reduce rake rather than adding front lift.
- Bolt-on design: Uses factory mounting points without drilling or welding.
- Heavy-duty steel construction: Finished in satin-black powder coat for corrosion resistance and a clean appearance.
- Pre-installed polyurethane bushings: Supplied in the shackles so you can get straight to installation.
- Made in the USA: Engineered and built by Apoc Industries.
Vehicle Fitment and Exclusions
- 2019–2026 Chevrolet Silverado 1500, new body style only.
- 2019–2026 GMC Sierra 1500, new body style only.
- 2WD and 4WD models, subject to the suspension exclusions below.
- Does NOT fit mono-composite leaf springs.
- Does NOT fit Classic body style, Active Ride, MagnaRide or aluminum mono-leaf rear suspension models.
Do not select this kit based on model year alone. Confirm the rear spring type and suspension equipment on your specific truck. If you are unsure, contact Apoc Industries with your vehicle and spring details before ordering.
What’s Included
- Two rear lowering shackles, driver and passenger side, in your selected drop size.
- Pre-installed polyurethane bushings.
- Installation instructions.
Installation and Drop Selection
Plan approximately 2 hours for installation using basic hand tools, a floor jack and jack stands. No drilling or welding is required. Follow the supplied installation instructions.
Choose the drop based on your truck’s current stance and desired rear ride height. Actual drop can vary with the spring configuration, spring condition and vehicle load; the selected size is not a guarantee that every truck will sit perfectly level.

Premium Bushings – Built for Life:
Apoc Premium Polyurethane Bushings
Backed by a Lifetime Warranty, Apoc Premium Polyurethane Bushings are built to outlast and outperform—delivering long-term reliability, quiet operation, and zero-compromise performance in every shackle kit we build.
Our premium bushings are crafted from high-density polyurethane to outperform standard rubber in every category:
- Resists cracking, shrinking, and dry rot – holds up in all climates and under load
- Low-deflection design – improves suspension responsiveness without harshness
- Noise-free fit – precision-molded for a tight, rattle-free connection
- Grease-retaining channels – accepts PTFE-based bushing grease for smooth, long-term articulation
Like all Apoc components, our bushings are built for abuse but refined for street use—giving you a durable, quiet, and dependable ride whether you're hauling, cruising, or cornering.
Important Installation Fitment Note:
Clearance Note – Rear Bed Support Trimming
- Rear bed support trimming is required for proper shackle clearance on some models.
- Contact may occur only at full suspension drop, such as when the vehicle is lifted off the ground for service.
- At normal ride height, the shackle remains clear and does not interfere with the bed support.

FAQ'S
Ford Lowering Shackles
Our customer support is available Monday to Friday: 9am-5pm EST. 865-983-5004
Do Lowering Shackles Affect Ride Quality?
In most cases: No, not significantly.
Lowering shackles drop the rear of the truck by relocating the rear leaf spring mounting point—not by removing leaf springs or altering spring rates. This means the suspension system continues to function much like stock.
✅ Why Ride Quality Usually Stays the Same
- Leaf Spring Geometry Is Preserved: The springs still carry the load the same way—they’re just mounted higher relative to the frame.
- No Change to Spring Rate or Shocks: Since you’re not swapping springs or shocks (for mild drops), the ride feel remains largely OEM.
- Polyurethane Bushings: Help maintain quiet operation and reduce flex, improving long-term ride consistency.
⚠️ Situations Where Ride May Be Affected
🔸 Reduced Suspension Travel: A 2" drop brings the axle closer to the frame. If bump stops aren't adjusted, you may hit them sooner over large bumps.
🔸 Increased Axle Angle or Leaf Spring Arching: Rare, but possible if combined with other drop components or a flip kit.
🔸 Towing and Hauling: With less rake, trucks may appear to sag more under load. Suspension upgrades like helper bags may be needed for heavy-duty use.
💬 Summary
For 1"–2" lowering shackles, ride comfort remains nearly identical to factory, making them one of the easiest and cleanest ways to drop the rear of your truck without compromising everyday drivability.
⏱️ Installation Time for Lowering Shackles
For most vehicles—including the 2004–2014 Ford F-150—installing rear lowering shackles typically takes:
🕒 Estimated Install Time: 1 to 1.5 hours
🔧 Install Overview
- Skill Level: Beginner to moderate (depending on experience with suspension work)
- Tools Needed:
- No cutting, welding, or fabrication is required. This is a bolt-on installation using factory mounting points.
- Most installs are done with basic hand tools in a home garage.
💡 Pro Tips
- Loosen leaf spring bolts with the truck on the ground before lifting for easier access.
- Use a pry bar or lift the axle slightly to relieve tension when aligning the new shackles.
- Always torque bolts to factory specs once the vehicle is back on the ground under full weight.
Can I Use Factory Hardware?
Yes — most 2004–2014 F-150s can reuse factory bolts. On some trucks, one bolt per side may need to be cut due to frame clearance. However, many have successfully removed the bolt without cutting.
A replacement bolt is included.
Replace hardware if rusted, damaged, or upgrading finishes.
Always torque at ride height for proper bushing preload.
🛢️ What Type of Grease Should I Use in Polyurethane Bushings?
Using the correct grease is essential for maintaining quiet, smooth operation and extending the life of polyurethane bushings—especially in suspension components like lowering shackles.
✅ Recommended Grease: Synthetic Waterproof Grease with PTFE (Teflon)
This type of grease is specifically designed for polyurethane bushings. It creates a slick barrier between the bushing and sleeve, preventing noise, binding, and premature wear.
🔧 Key Features to Look For:
- 🟩 PTFE-Based or Silicone-Based – Both are bushing-safe and reduce friction
- 🟩 Waterproof & Non-Petroleum – Resists washout and won’t degrade polyurethane
- 🟩 Thick, Tacky Formula – Stays in place during articulation and suspension travel
- 🟩 Non-Reactive – Safe for all types of polyurethane and metal sleeves
⚠️ Avoid These:
- ❌ Petroleum-Based Grease (like standard lithium or chassis grease) – Can cause polyurethane to soften, swell, or degrade over time
- ❌ WD-40 or Spray Lubricants – Not a true lubricant and quickly evaporates
💡 Pro Tip
Apply a generous coat of grease inside the bushing bore and on the sleeve during installation. If your shackles include zerk (grease) fittings, pump fresh PTFE grease in every 6–12 months for best performance.
