ROX4D Alpha & Apex Flat Floor
The industry's lightest weight steel dump bodies. 15% stronger and 1,200-2,500 lbs lighter than competitors.
Revolutionary Lightweight Design
ROX4D has redefined what's possible in steel dump body engineering. Using advanced Hardox 500 Tuff steel for the body and Strenx 110XF high-strength steel for longsills, ROX4D bodies deliver 15% more strength at approximately 4,500 lbs - that's 1,200-2,500 lbs lighter than traditional steel bodies.
Choose from two model lines - the versatile Alpha with multiple height options and fender materials, or the premium Apex with innovative single-piece sidewall and fender construction. Both available in three grades (Haul, Edge, Beast) to match your specific application.
