When you have a service body truck, finding a headache rack that fits that truck can be virtually impossible. Magnum’s Truck Bed Headache Rack meets that need, giving you the superior protection of a back rack that actually fits your vehicle. Created from templates based on every model of truck on the road, you’ll get a custom fit that you wouldn’t expect from an after-market back rack. The strong welded all aluminum frame has a black matte powder coat to provide durability while the light weight ensures you won’t lose more fuel efficiency from the addition.All truck racks include complete installation hardware kits (including a set of stake pocket tie downs where applicable).
