Rear Block Kit 2.25in 99-06 GM P/U

The ReadyLift Rear Block Kit 2.25in for 99-06 GM P/U trucks delivers a straightforward suspension lift solution engineered for full-size General Motors pickup trucks spanning the 1999–2006 model years. This leaf spring block kit raises the rear axle 2.25 inches, establishing a foundation for leveled stance or multi-stage lift configurations. The kit arrives complete with all necessary hardware, eliminating the need to source fasteners separately—a practical advantage for DIY installations and professional shops alike.

Constructed from iron in natural finish, the rear blocks integrate directly between the leaf springs and axle housing to achieve predictable, mechanical lift without the complexity of air suspension or coil conversions. The 2.25-inch specification represents a moderate elevation suitable for restoring factory rake geometry or pairing with complementary front suspension upgrades. At 17.33 lbs per kit, the blocks maintain reasonable weight addition while delivering the rigidity required for load-carrying trucks. Installation is accessible to owners with basic mechanical skill; the straightforward bolt-and-block design requires no extensive modification to the frame or suspension pickup points.

This kit appeals to truck owners seeking practical height gain for improved approach angles, enhanced appearance, or accommodation of larger tire diameters—without transitioning to full coilover or independent rear suspension systems. Common applications include work trucks prioritizing durability and serviceability, weekend haulers looking for modest visual stance correction, and multi-lift builds where staged elevation provides flexibility. The natural iron finish requires protective coating to resist corrosion in prolonged off-road or salt-exposure environments; aftermarket powder coating is a recommended maintenance step for long-term durability.
