Upgrade your GM 2500HD/3500 truck with McGaughy’s 4″ Premium Lift Kit, engineered to raise your truck’s stance, improve off‑road capability, and enhance ride quality on and off the pavement. Designed for both 2WD and 4WD models, this lift kit provides a balanced 4‑inch increase in ride height while maintaining solid handling and drivability.

This kit is built around McGaughy’s in‑house M84 Controlled Shocks , offering dampening performance designed to handle the added lift while providing a comfortable ride and reliable support for larger tires. All major components are powder‑coated black for durability and corrosion resistance.

Compatibility

Notes:

These lift kits fit standard suspension variants and AT4 trims but are not compatible with factory Multimatic DSSV Dampers found on AT4X or ZR2 models.

Whether you’re installing bigger tires, seeking improved clearance for off‑road trails, or aiming for a more aggressive stance, McGaughy’s 4″ Premium Lift Kits deliver a high‑quality, complete suspension upgrade that enhances both capability and ride quality on your GM HD truck.
