Built from CNC machined T6 billet steel, this kit aims to deliver durability and corrosion resistance for on road and light off road use.\u003c\/p\u003e\u003cp\u003eDesigned for 2007 to 2021 Silverado 1500 and Sierra 1500 4WD models, it is not compatible with 2007 Classic variants. Z71 and LTZ trims may require longer bolts to fit, and models equipped with SU4 or SU5 Differentials, such as certain 2019 to 2023 Silverado RST and Sierra Elevation, are not supported. After installation that changes vehicle height, an alignment is recommended to help ensure optimal steering and handling.\u003c\/p\u003e\u003ch3\u003eWhy consider a differential drop\u003c\/h3\u003e\u003cp\u003eDrivetrain geometry is key to smooth operation. The MZS kit may help minimize drivetrain bind by maintaining a more level transfer of power from front to rear, especially when the suspension is loaded or traversing uneven ground. It is a possibility you might notice a steadier feel under acceleration and during cornering, with potential improvements to axle alignment under load.\u003c\/p\u003e\u003ch3\u003eKey features and build quality\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNOTE: Only fits 6 Lug models.
