Apoc Industries Ford Super duty radius arm drop moves the radius arm mounting point down to maintain correct caster angles; when adding lift without a radius drop or proper radius arm for the lift, your alignment angles will be off, causing poor handling characteristics. Like death wobble and wandering (not wanting to stay straight while driving). 

Parts Included;

• Drivers and passenger side radius drop bracket
• 4- 3/4" bolts to mount the bracket to the factory bracket.

Install time;

• 1.5 hours
• Basic hand tools
