After lifting your 99-04 Ford Super Duty over six inch's without crossover steering or massive sector shaft sheering drop pitman arms, those over a 4 inch drop, you will likely need a steering coupler extension for your drag link.
This Extended Steering Coupler replaces the factory drag link steering coupler with a stronger, heavier duty, extended version of the factory part.
Sky Manufacturing has been using these huge machined steering couplers for years and have released them to the public now.
Machined from massive 1.5 OD hex rod, full size locking jam nuts, these make stamped steel with coupler bolts tiny in comparison.
6.125 inches overall length
2.5 inches of internal thread on each side
This is 1"-16 thread which is specific to these trucks.
