08-16' SD Rear Spring Swap - 1980-1997 Ford F-Series

Super Duty Rear Leaf Spring Conversion Kit (2" or 4" Flip) – 1980–1997 Ford Trucks & Vans

Description:
Upgrade your ride quality and towing capability by adapting modern Super Duty rear leaf springs to your 1980–1997 F-250/F-350, E-Series, Bronco, or F-150. This kit relocates the shackle and hanger mounts to accept longer 2008–2016 Ford Super Duty springs, offering a smoother ride, better load support, and modern geometry—all without needing factory blocks. No guesswork needed—mounts align with factory frame holes.
