1 Inch Lift Block Compatible With 1999-2024 Silverado 1500 and Sierra

In this review of the 1 inch rear lift block, the bottom line is simple: it is a practical, affordable way to raise the rear of 1999-2024 Silverado 1500 and Sierra 1500 trucks by 1 in for improved clearance and a more aggressive stance. The kit stands out for using 6061-T6 forged aluminum and CNC processing to deliver accurate fit and stable performance, and most owners will appreciate that installation can be completed in about 1-2 hours with no cutting or strut disassembly required.

Key Features

• Compatibility: Designed specifically for 1999-2024 Silverado 1500 and 1999-2024 Sierra 1500 models in both 2WD and 4WD, so fitment is straightforward for those trucks.
• Material and strength: Made from 6061-T6 aluminum forged alloy for a sturdy, corrosion-resistant lift block that balances weight and durability.
• Precision machining: CNC automatic processing with tight tolerances provides accurate hole positions, which simplifies installation and reduces alignment issues.
• Hardware quality: The kit includes pre-installed heat-treated 12.9 grade studs to ensure reliable clamping and long-term strength under load.
• Function: Raises the rear by 1 in to increase ground clearance, help clear off-road obstacles and allow fitting larger rims and tires for a more aggressive look.
• Installation ease: No cutting or drilling is required and no strut/coil disassembly is necessary, letting many owners finish installation within 1-2 hours.

Who It's For

This kit is aimed at Silverado and Sierra owners who want a modest, reliable rear lift to improve clearance, accommodate slightly larger tires, or correct a front-heavy rake. It is especially useful for drivers who prefer a quick, bolt-on solution that does not require complex suspension work.

Those who need larger lifts, full suspension overhauls, or modifications to front-end geometry should look elsewhere. Also, buyers who expect a larger change in ride height than the kit's 1 in lift or who require longer U-bolts for heavily modified trucks should double-check hardware fit before purchase.

Pros & Cons

Pros

• High-quality 6061-T6 aluminum construction provides a durable, lightweight lift solution.
• CNC precision machining ensures accurate hole positions for easier installation.
• Pre-installed heat-treated 12.9 grade studs add reliability and reduce initial assembly time.
• Simple, fast installation with no cutting or strut disassembly required.

Cons

• Lift is limited to a 1 in rear rise, so it is not suitable for drivers seeking larger lifts.
• Some customers report the supplied U-bolts may be short for certain setups, so replacement may be needed for modified trucks.
