6 Inch Lift Kit | Rear Springs | M1 | Ford F-250/F-350 Super Duty 4WD (1999)

Take your 1999 Ford F-250/F-350 Super Duty 4WD to the next level with this purpose-built 6 Inch Lift Kit featuring rear springs. Designed specifically for the rigors of a heavy-duty leaf-spring rear suspension, this kit delivers a substantial height increase while preserving the fundamentals that matter for work, play, and weekend adventures.

Why this rear-focused lift stands apart:

• Rear-only elevation delivers a bold, capable stance without altering the factory front geometry, giving you the look and clearance you crave while maintaining steering and handling behavior typical of a Super Duty.
• Enhanced ground clearance for rough trails, rock crossings, and muddy backroads—less risk of underside contact and improved ability to crawl over obstacles.
• Larger tire potential—the extra rear height creates more fender and wheel well clearance, opening up wheel and tire options to suit your off-road or work-day needs.
• Load-aware design to help maintain usable payload and towing capability for everyday tasks, long trips, or hauling gear on rugged ground.

What to expect in the installation and setup:

• Engineered specifically for the Ford F-250/F-350 Super Duty 4WD (1999) rear suspension, ensuring fitment with the truck’s leaf-spring layout.
• Professional installation is recommended to ensure proper alignment and to assess driveline angles, pinion angle, and potential shock or linkage adjustments.
• After installation, recheck alignment and inspect fasteners. Depending on your setup, longer shocks or updated rear components may be advised to optimize ride quality and control.

Ideal for drivers who demand confident off-road capability, payload-ready performance, and a standout stance from their classic Super Duty. Whether you’re tackling weekend camping trips, ranch work, or wilderness trails, this 6 Inch Lift Kit with rear springs helps you clear obstacles with more confidence and carry your gear with ease.
