PMF 8″ Alpha Suspension Lift Kit for '23–'24 Ford Super Duty

Upgrade your 2023–2024 Ford Super Duty (F-250, F-350) with performance, comfort, and towing strength.

The PMF 8″ Alpha Suspension Lift Kit offers a smooth street ride, added suspension travel, and a reinforced rear setup that handles high horsepower and heavy towing with ease.

Key Features & Benefits

• Comfort + Control:
  Dual-rate coil springs in front provide over 3″ more travel and a smoother ride on- and off-road.
  
  
• Strong Rear Performance:
  Maintains your factory leaf pack for load capacity, while adding a traction bar for stability and reduced axle wrap under heavy load.
  
  
• Heavy-Duty U-bolts:
  Upgraded to 3/4″ U-bolts (vs stock 5/8″) for increased strength. Available for both single-rear-wheel (SRW) and dual-rear-wheel (DRW) setups.
  
  
• Multiple Configuration Options:
  Customize based on bed length (Short or Long), front suspension setup, rear block height, leaf pack type, and shock options.
