DJM and Belltech are both good. Some say the belltech is better since it boxes the frame, but I believe my DJM is just as good. I am sure Mcgaughys makes a nice piece too since everything else they have is good quality.

 

I Have The Djm Notches. I Had Them Bolted In At First, And They Would Flex When The Truck Would Bottom Out (because Of The 4/6 Drop) And Bent The Bed Floor......i Had Them Welded And Boxed After That. Djm And Belltech Are Both Good. Just Make Sure You Weld Them To Be Safe.
