Hooker BlackHeart Suspension CrossmemberThis rear suspension crossmember is designed for use on lowered trucks and eliminates driveshaft clearance issues & maintains proper pinion angle.

This crossmember replaces the factory part in the stock location, and works with the factory trailing arms, along with all Hooker Blackheart
