Apoc Industries proudly builds these premium fabricated steel lift blocks right here in East Tennessee for Super Duty owners who refuse to compromise.

Why Apoc Anti-Wrap Lift Blocks with Bump Stops Excel
- β Compound Taper Technology β Top taper perfectly matches factory OEM leaf spring angle for ideal seating and load distribution. Bottom taper maintains proper pinion angle β keeping wheels centered, protecting your drivetrain, and eliminating vibrations or U-joint stress even on taller lifts.
- π‘οΈ Integrated Bump Stops β Built-in bump stops prevent harsh bottoming out, improve ride control, and add extra protection when loaded or off-roading β a premium feature you won't find on standard blocks.
- β Anti-Wrap Design β Reinforced wider footprint dramatically cuts axle wrap, wheel hop, and spring twist under heavy torque or towing.
- πͺ Built Tough for Work & Play β Pressure-bent 1/4" steel, precision robotic welds, and durable satin black powder coating deliver zero-flex durability that stands up to the harshest conditions.
- π Exact Super Duty Fit β Vehicle-specific for 2017-2025 F-250 & F-350 leaf springs with precise center pin locations β no modifications required.
Perfect for achieving that aggressive lifted stance, extra ground clearance for bigger tires, improved towing capability, or off-road readiness β all while keeping your Super Duty stable, reliable, and protected.

Compound Taper Technology
Apoc Anti-Wrap Lift Blocks are the first ever with exclusive compound tapers. The top taper matches your factory OEM leaf spring angle for perfect seating, while the bottom taper maintains proper pinion angle at your chosen lift height.
The Problem with Standard Blocks
Most lift blocks only correct pinion angle and ignore the leaf spring angle. The taller the block, the further back they push your axle β throwing wheels off-center in the fenders and over-extending your driveshaft, which can damage your transfer case.
Benefits of Apoc Anti-Wrap Lift Blocks
Our heavier-duty steel construction with precision robotic welds delivers zero flex and maximum strength. The anti-wrap geometry keeps your axle centered, protects your drivetrain, and provides a stable ride β perfect for serious off-roaders, daily drivers, and tow vehicles.
FAQ'S
Lift Blocks
Here are some of the most common questions we receive about lift blocks, installation, and related components. Our goal is to help you make the best decision for your build with clear, practical information.
A: Yes. Apoc lift blocks are true to sizeβthe height listed is the actual block height, providing that exact amount of rear lift when installed. For example, a 3" block adds 3" of lift over your current leaf spring height.
A: Apoc lift blocks are vehicle-specific and engineered to match your truckβs factory leaf spring setup. The alignment hole and center pin locations are precisely positioned to match OEM specs, ensuring a secure, direct fit with no modifications required.
The main U-bolts are required to secure the axle and block assembly to your leaf springs. You do not have to purchase them from us if your existing U-bolts are long enough. However, if you are changing the size of your lift block, you will need longer U-bolts. Simply measure the difference in height between your current block and the new block β your new U-bolts will need to be that much longer than your current ones.
Anti-wrap U-bolts are optional. They are designed to secure the wider footprint of the block more firmly to the leaf spring, helping to reduce axle wrap, spring twist, and wheel hop. The taller the block, the more beneficial anti-wrap U-bolts become. For block heights over 6 inches, we recommend also installing ladder bars for added stability and to prevent driveline issues.
A: Standard blocks provide basic lift, while anti-wrap blocks feature a wider footprint and additional bracing to reduce axle wrap and wheel hopβespecially important for lifted trucks with big tires or high torque output.
A: No, stacking lift blocks is not recommended and can be dangerous. It compromises stability, increases the risk of axle shift, and can cause premature wear or failure of suspension components. Always use a single, properly sized Apoc lift block for safe, reliable performance.
