4 Inch Lift Kit | 56 Inch Rear Springs | Chevy/GMC 3/4-Ton Suburban/C25/K25 Truck (73-76)

Elevate your classic GM workhorse with confidence. This 4 Inch Lift Kit is purpose-built for 1973–1976 Chevy/GMC 3/4-Ton trucks, including Suburban, C25, and K25 models, delivering a robust upgrade that respects the truck’s heavy-duty heritage. Paired with 56 inch rear springs, it creates a balanced, capable stance that enhances both payload handling and off-road potential.

Why this lift kit stands out

• 4-inch front lift engineered to preserve steering geometry and braking response on heavy-duty 3/4-ton Chevy/GMC chassis, so you gain ground clearance without compromising control.
• 56-inch rear springs designed to support substantial payloads while maintaining a level, stable ride under load, reducing rear sag during hauls or towing.
• Classic compatibility precisely matched for 1973–1976 Suburban, C25, and K25 configurations, keeping the truck’s original feel while expanding capability.
• Rugged, durable construction built for the rigors of heavy-duty use—trail, job site, or daily driver—with components chosen to withstand the demands of old-school GM suspension.
• Wider tire options and improved stance with a lift that improves approach/departure angles and ground clearance, enabling more versatility in terrain and applications.

What you gain in real-world use

Whether you’re swapping to a larger tire for off-road adventures, carrying heavier loads, or just restoring a classic with a more commanding presence, this kit delivers a practical mix of height, stability, and control. The front lift opens up room for upgraded wheels and tires, while the rear springs keep your RPO-equipped chassis level when loading up gear, tools, or passengers.

Fitment, installation, and care

Designed specifically for 1973–1976 Chevy/GMC 3/4-Ton trucks, including Suburban, C25, and K25, this lift kit is best installed by a qualified technician familiar with vintage GM suspensions. Expect required checks for ride height alignment, steering geometry, and possible driveshaft or brake-line considerations after a lift. Regular inspection of leaf springs, mountings, and hardware helps preserve performance over time.

Ideal for

• Classic GM 3/4-ton owners looking to reclaim off-road readiness without sacrificing payload capability
• Collectors and restorers adding a functional lift to a Suburban or heavy-duty pickup
• Truck enthusiasts seeking a balanced stance that complements heavy-duty axles and leaf-spring setups

With the 4 Inch Lift Kit and 56 Inch Rear Springs, your 1973–1976 Chevy/GMC 3/4-Ton Suburban/C25/K25 will stand taller, ride steadier under load, and open the door to broader wheel-and-t tire choices—while preserving the rugged, reliable character these classic GM trucks are known for.
