This rear frame crossbeam sells steadily in my store. Solid steel structure, zero deformation under heavy loads, my truck clients keep placing repeat orders.
Mounting holes match perfectly with original frames, no cutting needed. Anti-rust coating holds up well on muddy roads, great aftermarket replacement part.
