KSP PERFORMANCE 2" Lift Block for Silverado/Sierra 2500HD (2000–2010) — CNC Steel, Square U‑Bolts

KSP PERFORMANCE 2" lift block kit raises the rear of compatible Silverado/Sierra 2500HD trucks by two inches using a CNC-machined steel block and heavy-duty square U-bolts for stronger support and improved tire clearance.

This lift block set is engineered to add a modest rear lift to 2000–2010 Chevrolet Silverado and GMC Sierra 2500HD trucks (non-dually, non-3500, and not for models with factory overload springs). The kit combines a precision-machined steel spacer, corrosion-resistant black powder coat, and extended M16 U-bolts to restore ride height, allow larger wheels/tires, and deliver an aggressive stance without cutting or welding. Installation is straightforward with common hand tools and typically takes about two hours per axle; wheel alignment is recommended after fitment.

How does this block improve rear clearance and stance?

The 2" spacer lifts the rear axle relative to the leaf springs, increasing ground clearance and enabling the use of taller tires while correcting sag from heavy loads. The block’s larger contact footprint distributes load more evenly than narrow OEM blocks, reducing stress on spring leaves.

• 2-inch lift height for noticeable clearance and stance changes
• Wider contact area minimizes concentrated pressure on springs
• CNC-machined steel resists deformation under load
• Black powder coat resists corrosion for long-term durability

Will these parts fit my truck and what vehicles are excluded?

This kit is built for Silverado/Sierra 2500HD trucks from the 2000–2010 model years but does not fit dually (dual‑rear-wheel) models or any 3500 series trucks. It is also not intended for vehicles equipped with factory overload springs; always verify your exact year, model, and axle configuration before ordering.

• Compatible: 2000–2010 Chevy Silverado 2500HD and GMC Sierra 2500HD (single rear wheel)
• Not compatible: Dually models, 3500 models, or trucks with factory overload springs
• Confirm axle type and spring setup prior to purchase

What hardware and materials are included, and how durable are they?

The kit pairs a CNC-machined steel lift block with extended square U-bolts using a coarse M16x1.5 thread pitch. The bolts are grade 10.9 with a black electrophoretic finish that helps prevent rust, while the block’s powder coat provides additional corrosion resistance and a factory-clean appearance.

• CNC-machined steel block for precise fit and strength
• Extended M16x1.5 square U-bolts for secure clamping
• Grade 10.9 bolts with black electrophoresis finish for corrosion resistance
• Cross gusset plate design locks the block for added support

How difficult is installation and what should I prepare?

Installation is designed for do-it-yourselfers familiar with basic axle and suspension work. No cutting or welding is required; common hand tools and a jack with stands are usually sufficient. Plan approximately two hours for a rear-side installation and schedule an alignment after the lift is installed to ensure correct handling and tire wear.

• Tools needed: jack, jack stands, wrenches, torque wrench
• Typical install time: ~2 hours per axle with common hand tools
• No cutting or welding required—bolt-on design
• Alignment recommended after installation

Who is this kit for? Owners of single-rear-wheel Chevrolet Silverado or GMC Sierra 2500HD trucks (2000–2010) who want a modest 2" rear lift to correct sag, fit larger tires, or achieve a more aggressive rear stance will find this kit well suited. It’s ideal for DIY mechanics who prefer bolt-on upgrades with durable materials and corrosion-resistant finishes. If your truck is a dually, a 3500 model, or uses factory overload springs, choose a different solution or consult a specialist for proper fitment.
